Background

Due to anterior bone defects, high and/or posterior placement of an acetabular cup is often required to achieve sufficient coverage in patients with hip dysplasia. We examined whether posterior cup placement affected the postoperative range of motion (ROM) in primary total hip arthroplasty (THA).

Methods

Using computer software, bone coverage and ROM were examined in 32 patients with unilateral osteoarthritis of the hip with Crowe type II or III hip dysplasia. We determined the cup position to satisfy cup center-edge (Cup-CE) angle ≥0° and the required ROM. The cup was placed at the anatomic hip center and moved in 2-mm increments anteroposteriorly and 10-mm increments vertically.

Results

At vertical anatomic hip center, less than 68.8% hips fulfilled Cup-CE ≥0° regardless of anteroposterior position. Significantly more hips at higher hip center with posterior cup placement achieved Cup-CE ≥0° than hips at vertical anatomic hip center, and 10 mm higher hip center was the most suitable for achieving bone coverage. However, posterior and superior cup placement significantly decreased the flexion and IR due to early bone impingement, whereas ER and extension were not affected. A smoothing spline curve demonstrated that more posterior cup placement than 4.8 mm and 3.6 mm did not satisfy the required ROM at 10 mm and 20 mm higher hip center, respectively.

Conclusions

Posterosuperior cup placement gained more bone coverage but decreased the range of hip flexion and internal rotation. Consequently, posterosuperior cup placement did not satisfy the required ROM.  相似文献

Background

Biologic agents (BAs) enabled not only a reduction of disease activity but also a slowing down of structural damage to the joints in patients with rheumatoid arthritis (RA). However, the incidence of cervical lesions in patients with RA is still high.

Purpose

To elucidate the predictors for the progression of two different cervical lesions in patients with RA under BA treatment.

Methods

Of 151 subjects who received more than two years of continuous BA treatment, 101 subjects who had cervical X-ray images taken at baseline and final visit were enrolled. The mean disease duration and mean radiography interval were 10.6 years and 4.4 years, respectively. The existence and progression of cervical lesions (atlanto-axial subluxation [AAS], vertical subluxation [VS], and subaxial subluxation [SS]) were investigated. And predictors for the AAS or VS progression were analyzed by multivariate logistic regression analysis.

Results

The incidence of cervical lesions at baseline were no pre-existing cervical lesion (none) in 50 cases (50%), AAS only in 32 (32%), both AAS and VS in 12 (12%), and VS only in 7 cases (7%). In the none group, only 4 cases of AAS progression (8%) was observed during the follow-up. In contrast, in the groups with pre-existing cervical lesions, a high incidence of VS progression was observed (63% in the AAS only group, 58% in the AAS + VS group, and 71% in the VS only group). Multivariate regression analysis demonstrated that the DAS-CRP value at baseline (odds ratio [OR] = 9.23) and matrix metaloprotease-3 level at baseline (OR = 1.01) were significant predictors for the progression of AAS, and pre-existing AAS (OR = 18.38) was a sole significant predictor for the progression of VS.

Conclusions

Cervical lesions progressed irrespective of disease activity after AAS development. Strict disease control before the development of AAS is crucial for preventing further progression and development of cervical lesions.  相似文献

Objective

The aim of this study was to evaluate the radiologic outcomes of open reduction and lateral plating with wiring in the treatment of Vancouver B2 periprosthetic femoral fractures.

Methods

We retrospectively recruited 37 patients treated with ORIF with lateral plating and wiring for Vancouver B2 fractures. The 27 patients (15 men and 12 women; mean age: 70.8 ± 8.3 years) without follow-up loss had achieved complete bony union without notable complications. The average union period was checked after operation with radiologic findings. Radiologic outcomes were evaluated by ipsilateral limb length discrepancy (LLD) and subsidence between immediate postoperative length and length at postoperative 1 year after adjusting for magnification differences. The average distance to which the retained stem sunk down was investigated between immediate postoperative radiographs and final radiographs showing union.

Results

Ten patients could not be evaluated, because of mortality or failure to follow up. The average time to union was 18.3 weeks, and the average distance of stem sinking was 2.5 ± 1.7 mm (range: 0–7.2 mm), which was significantly different between immediate postoperative radiographs and final radiographs. There was no case with loss of reduction or loss of fixation, requiring revision surgery.

Conclusion

Open reduction and lateral plating with wiring as a treatment for Vancouver B2 periprosthetic femoral fractures produced good radiologic outcomes with successful bony union. ORIF can be considered the alternative option for treating patients with Vancouver B2 PPF, instead of stem revision surgery.

Background

Because the relationship between coaches and athletes is unequal, verbal and physical abuse remains a common problem among sports coaches. We aimed to elucidate the characteristics of baseball coaches who verbally/physically abuse young baseball players.

Methods

A cross-sectional study was conducted on youth sports team coaches in Miyagi prefecture, Japan (n = 380), using a self-reported questionnaire. Multivariate logistic regression models were used for the analyses, evaluating the following variables: sex, age, educational level, smoking habits, years of coaching, level of baseball-playing experience, personal experience with verbal/physical abuse by former coaches, satisfaction with athletes’ attitudes, number of athletes on the team, team competition level, awareness of the recommendations of the Japanese Society of Clinical Sports Medicine, limitations in the total pitch count, difficulty in coaching in other positions, number of games per year, and acceptance of former verbal/physical abuse.

Results

The prevalence of verbal/physical abuse toward young athletes was 74.5% (n = 283) and 6.6% (n = 25), respectively. Verbal abuse was significantly associated with personal experience of verbal abuse by former coaches (odds ratio [OR]: 2.00, 95% confidence interval [95% CI]: 1.04–3.85), and acceptance of verbal/physical abuse (OR: 2.61, 95% CI: 1.34–5.10). Physical abuse was significantly associated with greater than 10 years of coaching experience (OR: 7.16, 95% CI: 1.36–37.78), personal experience with physical abuse by former coaches (OR: 4.25, 95% CI: 1.23–14.70), and acceptance of verbal/physical abuse (OR: 3.85, 95% CI: 1.51–9.84).

Conclusions

Coaches’ experiences with verbal/physical abuse by former coaches negatively affected young athletes. Breaking this cycle is necessary to keep athletes active and interested in playing baseball.

Objective

The aim of this study was to analyze the survivorship and clinical outcome of Cementless Spotorno (CLS) stem in young patients.

Methods

A total of 99 consecutive hip arthroplasties using CLS stem were performed on 84 patients younger than 50 years of age between 1993 and 2001. 63 patients were available for final follow-up (mean age: 39 ± 7.8 (range: 22–50)). Patients' Harris Hip Scores (HHS) and survivorship estimates were calculated. Radiographs were analyzed for acetabular implant status, canal fill index (CFI), stem alignment, osteolysis, and stress shielding.

Results

Mean follow-up time was 18 years (13–3), and mean HHS was 88.7 (58–100). Patients with femoral neck fracture had a more favorable functional outcome (p = 0.027), while those with stems in varus had lower scores (p = 0.017). 31 stems (49%) were undersized and 30 hips (47%) had perifemoral osteolysis. Acetabular impairment was strongly associated with osteolysis in Gruen zones 1 and 7 (p < 0.01). Seventeen of the osteolytic lesions occurred in Gruen zone 1, 4 lesions in zone 2, 9 in zone 6 and 22 in zone 7. Forty nine stems were well aligned, 10 were in varus and 5 in valgus. Six patients presented with grade 1 stress shielding, 42 with grade 2, 9 with grade 3 and 7 with grade 4. Pedestal formation was evident in 13 cases. Kaplan-Meier survivorship estimates at 18 years with revision for any reason as the end point and with septic revisions excluded were 91.2% (95% CI: 83.7%–98.7%) and 95.1% (95% CI: 89.5%–100%), respectively. There was no difference between survival estimates of patients with different etiologies.

Conclusion

CLS stems in young patients have high survival estimates in the long term with good-excellent results. Spotorno stems perform equally well in all etiologies with no difference in terms of survivorship.

Background

It is unclear whether smaller rotator cuff tears cause cartilage degeneration. This study was designed to detect early humeral head cartilage degeneration in patients with small-to-medium cuff tears using magnetic-resonance-imaging T1 rho mapping.

Methods

Five male and 5 female volunteers without shoulder symptoms (control group) and 5 male and 5 female patients with small-to-medium (<3 cm) rotator cuff tears underwent 3.0-T magnetic resonance imaging of a single shoulder. T1 rho values of the humeral head cartilage were measured and analyzed.

Results

The total mean T1 rho value was 40.4 ± 3.4 ms for the control group and 45.0 ± 5.3 ms for the patient group. In the control group, the T1 rho values in the inferior articular cartilage were significantly higher than those in the superior and middle articular cartilage. In the patient group, there was no significant difference between all regions. A comparison between the patient and control groups showed that the mean T1 rho values in the superior-to-middle articular cartilage were significantly higher for the patient group than for the control group. However, in the inferior articular cartilage, there was no significant difference between both groups.

Conclusions

This study showed the possibility of early cartilage degenerative changes in the superior-to-middle humeral head articular cartilage of patients with small-to-medium rotator cuff tears.  相似文献

Introduction

The refusal to consider death and the donation and transplantation of organs make Gypsies one of the subpopulation groups with the lowest donation rates in Europe. The approach of this social group implies the support of the most favorable social groups within their own ethnic group. In this sense, the young population with a high level of education is usually the most favorable toward organ donation.

Objective

To analyze the attitude toward the donation of one's own organs for transplantation among the Gypsy population under 45 years and with secondary or university studies.

Method

Population under study: The Gypsy population under 45 years old with secondary or university studies who currently reside in Spain. Assessment instrument: The attitude questionnaire for organ donation for transplantation PCID–DTO Ríos. Fieldwork: A random selection based on stratification. Anonymity and self-administered fulfillment. Statistics: Student t test and χ2.

Results

A total of 44 Gypsy people under 45 years of age were surveyed (mean age 31 ± 8.9 years); 66% were women, and the rest were men. Of these, 20 had university studies, and 24 had secondary or vocational studies. The attitude is favorable toward organ donation in 64% of the respondents, with 80% among university students and 50% among those with secondary or vocational education (P < .005).

Conclusions

The young Gypsy population with university studies has a very favorable attitude toward organ donation. This population subgroup must be key in the promotion of organ donation in the Gypsy population, so the transplant coordinators must request their collaboration in the promotion campaigns of organ donation and transplantation.  相似文献

Purpose

Creating a trough on the anterior glenoid rim is one of the methods used for arthroscopic Bankart repair with suture anchors. The purpose of this study was to analyze clinical and radiological outcomes of arthroscopic Bankart repair with suture anchors; to compare between the outcomes of surgical procedures with and without trough.

Methods

Clinical and radiological outcomes were evaluated for 116 patients who underwent arthroscopic Bankart repair at our institute from 2005 to 2011. The mean follow-up was 5.2 years (range, 2–8.8 years). All data were divided into trough group (n = 62) and non-trough group (n = 71). Clinical and functional outcomes were assessed pre- and postoperatively as range of motion (ROM), pain on the visual analog scale (p-VAS), function on the visual analog scale (f-VAS), and Rowe score. Radiological outcomes were also evaluated.

Results

The overall postoperative clinical and functional outcomes improved significantly (P < .001). A total of 8 patients (6.8%) showed recurrent instability. Radiologic findings showed mild arthritis in 27 cases (23.1%), moderate arthritis in 6 cases (5.1%), and no severe arthritis. 32 patients showed anterior apprehension after surgery, and 22 out of those 32 patients were from non-trough group. However, no significant difference between the trough and non-trough groups was found with respect to clinical and functional outcomes (P > .05).

Conclusion

The additional procedure of creating a trough did not improve clinical outcomes in terms of frank dislocation; however, at the final follow-up, patients with the trough showed less anterior apprehension. Overall, arthroscopic Bankart repair using suture anchors had relatively good clinical outcome, with a redislocation rate of 6.8%.

Objectives

The aim of this study was to evaluate the clinical and radiological results of the surgical treatment of acetabular fractures using modified Stoppa approach.

Methods

A total of 57 patients (mean age 37.8 years; range 15–84) who underwent surgical treatment for acetabular fracture with modified Stoppa approach from February 2013 to June 2016 were included into the study. The mean follow-up time was 28.1 months (range 24–35). The records were reviewed for fracture patterns, time to surgery, operative time, blood loss, reduction quality, and perioperative complications. Reduction quality was graded as anatomic, imperfect, or poor. The Harris Hip Score (HHS) and Merle d'Aubigné score were used for functional evaluation.

Results

Among the 63 acetabulum fractures of the 57 patients, 27 were associated with both columns, 12 were T-type fractures, 10 were transverse, 7 were anterior column/posterior hemitransverse, 5 were anterior column, and 2 were anterior wall fracture. A single surgeon performed all operations. Pfannenstiel incision was used in the first 19 cases while vertical midline incision in the remaining 38 cases. Average time to operation was 5.5 days, and supplemental lateral windows were used in 17 (29.8%) patients. Average blood loss and operation times were 660 mL and 152 min, respectively. Radiological outcomes were anatomic, imperfect, and poor in 52 (82.5%), 9 (14.2%), and 2 (3.2%) of the acetabulum fractures, respectively. Clinical outcomes at 2 years with HHS and Merle d’Aubigné scores were mean 86.6 (range 66–96) (Excellent in 27, good in 23, fair in 4, poor in 3 patient) and 16.7 (range 10–18) (Excellent in 25, very good in 18, good in 6, fair in 5, poor in 3 patient), respectively. There was a significant relation between the reduction quality and clinical outcome (p < 0.001), while there was no significant relation between the clinical outcome and the fracture type (p > 0.05). Iatrogenic external iliac vein damage was noted in 2 patients. Obturator nerve palsy was noted in 3 patients, who recovered spontaneously at mean time of 3.7 months (range 3–5). Rectus abdominus paralysis was noted in 2 of the 19 (10.5%) Pfannenstiel-incision patients but not in the vertical-incision patients.

Conclusion

Our experience in 57 patients shows that satisfactory results can be obtained, even in bilateral fractures with vertical midline incision.

Objective

The aim of this study was to evaluate the efficacy of conservative treatment (cast immobilization) for complex intra-articular distal radius fractures (AO type C) in elderly patients and to determine whether or not the application of a volar locking plate (VLP) is necessary.

Methods

A retrospective study on patients treated at two different clinics was conducted between 2014 and 2016. A total of 49 elderly patients ≥60 years old were treated either operatively with volar locking plate fixation (n = 25; 7 males and 18 females; mean age: 66.6 ± 7.4 years) or conservatively with cast immobilisation (n = 24; 7 males and 17 females; mean age: 68.9 ± 8.7 years) for complex intra-articular distal fractures. Clinical, functional and radiological evaluations were conducted at the final follow-up examinations of the patients.

Results

There was no statistically significant difference between the two groups of patients with respect to the follow-up periods, gender, age and fracture type (p > 0.05). At the end of mean follow-up time of 16 months the grip strength (p = 0.03), radial tilt (p = 0.06), radial inclination (p = 0.01), radial height (p = 0.01) and articular step-off (p = 0.02) were significantly better in the volar locking plate group, while there was no significant difference between the functional results (based on the Quick Disabilities of the Arm, Shoulder and Hand score) (p = 0.8) and range of motion. The grip strength was significantly higher in the VLP group when compared to the cast group (p = 0.03).

Conclusion

The results of this study suggest that the locking plate fixation for the complex intra-articular distal radius fractures provides better results for the grip strength and radiographic parameters than cast immobilization in patients ≥60 years old, while no difference was found between the clinical and functional results.

Study Design

Two-group randomized controlled trial.

Introduction

Upper limb orthoses worn during functional tasks are commonly used in pediatric neurologic rehabilitation, despite a paucity of high-level evidence.

Purpose of the Study

The purpose of this study was to investigate if a customized functional wrist orthosis, when placed on the limb, leads to an immediate improvement in hand function for children with cerebral palsy or brain injury.

Methods

A 2-group randomized controlled trial involving 30 children was conducted. Participants were randomized to either receive a customized functional wrist orthosis (experimental, n = 15) or not receive an orthosis (control, n = 15). The box and blocks test was administered at baseline and repeated 1 hour after experimental intervention, with the orthosis on if randomized to the orthotic group.

Results

After intervention, there were no significant differences on the box and blocks test between the orthotic group (mean, 10.13; standard deviation, 11.476) and the no orthotic group (mean, 14.07; standard deviation, 11.106; t[28], ?0.954; P = .348; and 95% confidence interval, ?12.380 to 4.513).

Discussion

In contrast to the findings of previous studies, our results suggest that a functional wrist orthosis, when supporting the joint in a ‘typical’ position, may not lead to an immediate improvement in hand function.

Conclusions

Wearing a functional wrist orthosis did not lead to an immediate improvement in the ability of children with cerebral palsy or brain injury to grasp and release. Further research is needed combining upper limb orthoses with task-specific training and measuring outcomes over the medium to long term.  相似文献

Introduction

The sensitization of the population toward organ donation is fundamental; for that reason, it is important to determine the factors that condition the opinion toward donation on the population scope in order to carry out cost-effective campaigns.

Objective

To analyze the attitude toward the donation of the proper organs for transplantation among the population residing in Cienfuegos, Cuba.

Method

Population under study: Population who reside in Cienfuegos, Cuba. Inclusion criteria: Population over 15 years old as stratified by age and sex. Assessment instrument: The attitude questionnaire for organ donation for transplant—PCID–DTO Ríos. Fieldwork: A random selection based on stratification. The available data from the census were used. The completion was anonymous and self-administered. Verbal consent was requested to collaborate in the study. Statistics: Student t test, χ2, Fisher, and a logistic regression analysis.

Results

A sample of 636 respondents was included in the study, of which 71% (n = 453) are in favor of donating their organs after death, 16% (n = 103) are against, and 13% (n = 80) are undecided. This attitude is associated with different psychosocial variables (P < .001): age, marital status, having offspring, level of studies, carrying out prosocial activities, discussing with the family the subject of donation and transplantation, knowledge of the concept of brain death, the attitude toward the manipulation of the corpse, the religion of the respondent, and the attitude of the couple toward organ transplantation. The main independent factors obtained in the multivariate analysis (odds ratio >2.5): knowledge of the brain death concept, attitude toward the manipulation of the corpse, religion, and attitude of the couple toward transplantation.

Conclusions

The attitude toward organ donation among the population of Cienfuegos, Cuba, is favorable and is conditioned by several psychosocial factors.  相似文献

Background

Surgical strategy for pyogenic spondylitis is controversial when vertebral body erosion is severe. Radical debridement and anterior column reconstruction is indicated for the purpose of early ambulatory to prevent secondary complication for long bed rest. However, such aggressive debridement and risk of perioperative complications are trade-off. The purpose of this study was to evaluate the risk factor of poor prognosis after anterior column debridement and reconstruction for pyogenic spondylitis in lower thoracic and lumbar spine.

Methods

We performed a retrospective review of 40 patients diagnosed with pyogenic spondylitis in lower thoracic and lumbar spine who were introduced to our institution due to losing ambulatory ability and underwent anterior column debridement and reconstruction between January 2008 and May 2016. After the patient population was split into a regaining ambulatory group (Group A; n = 23) and a poor prognosis group (Group P; n = 17), we used Fisher exact tests and t-tests as appropriate for univariate analyses to compare patient characteristics and outcomes between the 2 groups.

Results

Univariate analysis showed that the significant variables were massive bleeding (>2000 ml) (P < 0.01), Charlson Comorbidity Index ≥3 (P = 0.01), and two-stage surgery needed (P = 0.04). Logistic regression analysis showed that the factors associated with poor prognosis were massive bleeding (Odds Ratio 11.9; 95% confidence interval 1.8 to 119.7; P = 0.04).

Conclusions

Massive bleeding was associated with poor prognosis after debridement followed by anterior column reconstruction for pyogenic spondylitis in lower thoracic and lumbar spine.  相似文献

Background

Esophagectomy has high cardiac and pulmonary complication rates that can reach 43% and 58% respectively. The original Ivor Lewis esophagectomy was a two-stage procedure. We revisited this procedure using a hybrid minimally-invasive approach.

Methods

Thirty-five consecutive patients with esophageal cancer were operated on over an eight-year period. The first stage used laparoscopic mobilization of the stomach, while the second stage used open thoracotomy. Six patients were aborted due to unresectable disease.

Results

Twenty-nine patients were studied. The mean operative times for stage-one and stage-two were 108?±?18 and 226?±?63?min respectively. All patients were extubated in the operating room. One (3.4%) patients had cardiac complication and one (3.4%) patient had pulmonary complication.

Conclusion

Metachronous hybrid two-stage esophagectomy was associated with a low rate of cardio-pulmonary complications. It may be considered as an alternative to the one-stage esophagectomy, especially in low-volume centers, to decrease these high-risk cardio-pulmonary complications.  相似文献

Introduction

Religious factors have conditioned the attitude toward organ donation and transplantation (ODT) since the beginning of transplantation, despite the fact that most religions are in favor of transplantation.

Objective

To assess the impact of religious beliefs of medical students on their attitude toward ODT.

Method

Population under study: Medical students in Spanish universities. Study sample: Stratified by geographical area and academic course. Assessment instrument: Attitude ODT questionnaire PCID-DTO-Ríos, anonymous and self-administered.

Results

Of all students, 42% (n = 3907) declare themselves atheists or agnostics. The remaining 58% (n = 5368) declare themselves to be religious, the majority being Catholic (55%, n = 5102). Of the rest, 0.2% are Muslims (n = 8), 0.1% Protestants (n = 1), and the remaining 2.7% (n = 257) indicate other religious doctrines but do not want to specify it. Regarding their attitude toward ODT, those who consider themselves atheists or agnostics have a more favorable attitude than those who consider themselves religious (84% versus 76%; P < .001). Among those who follow some kind of religion, Catholics are more in favor of ODT than non-Catholics (77% vs 64%, P < .001). Note that among the religious, only 57% (n = 3050) know which religion is in favor of transplantation, while 22% (n = 1,152) consider that it has not been pronounced on the matter, 13% (n = 723) think the religion is against donation, and the remaining 8% (n = 443) do not know.

Conclusion

The religion professed by medical students conditions their attitude toward donation, with the atheists and agnostics being more in favor of donation.  相似文献

Introduction

Negative organ donation rates among the Gypsies is much higher than that of any other social group in Spain. However, living donation rates have not been raised much in this social group, despite the existence of several Gypsy patients on the waiting list for transplantation.

Objective

To analyze the attitude toward related living donation among the Gypsy population who reside in Spain.

Methods

This type of study is an observational sociological study. The study consisted of the adult Gypsy population residing in Spain, and a random sampling of 230 adult gypsies was conducted. Attitude questionnaires for live donation, both hepatic PCID-DVH-Ríos and renal PCID-DVR-Ríos, were used, and random selection was based on stratification. Questionnaires were self-administered and completed anonymously. Student t test, χ2, Fisher, and a logistic regression analysis were used.

Results

A sample of 206 Gypsies (52% women) with a mean age of 34 years is obtained. Seventy-two percent (n = 150) would donate an organ to a relative in life, 8% (n = 16) would not donate it, and 20% (n = 41) have doubts. Respondents with a favorable attitude toward living donation presented a more favorable attitude toward cadaveric organ donation (55% vs 0%, P < .001). The attitude toward living kidney donation was more favorable (81% in favor) than toward living liver donation (P < .001).

Conclusions

The Gypsy ethnic group is sensitized to live donor transplantation. The family and cultural roots of Gypsy people could condition this favorable attitude, a fact to be taken into account to sensitize this social group and promote donation campaigns with the aim of increasing donation rates.  相似文献

Objective

To compare perioperative and long-term outcomes in patients undergoing hemiarch and aggressive arch replacement for acute type A aortic dissection (ATAAD).

Methods

From 1996 to 2017, we compared outcomes of hemiarch (n = 322) versus aggressive arch replacements (zones 2 and 3 arch replacement with implantation of 2-4 arch branches, n = 150) in ATAAD. Indications for aggressive arch were arch aneurysm >4 cm or intimal tear in the aortic arch that was not resectable by hemiarch replacement, or dissection of arch branches with malperfusion.

Results

Patients in the aggressive arch group were significantly younger (mean age: 57 vs 61 years old) and had significantly longer hypothermic circulatory arrest, cardiopulmonary bypass, and aortic crossclamp times. There were no significant differences in perioperative outcomes between hemiarch and aggressive arch groups, including 30-day mortality (5.3% vs 7.3%, P = .38) and postoperative stroke rate (7% vs 7%, P = .96). Over 15 years, Kaplan–Meier survival was similar between hemiarch and aggressive arch groups (log-rank P = .55, 10-year survival 70% vs 72%). Given death as a competing factor, incidence rates of reoperation over 15 years (2.1% vs 2.0% per year, P = 1) and 10-year cumulative incidence of reoperation (14% vs 12%, P = .89) for arch and distal aorta pathology were similar between the 2 groups.

Conclusions

Both hemiarch and aggressive arch replacement are appropriate approaches for select patients with ATAAD. Aggressive arch replacement should be considered for an arch aneurysm >4 cm or an intimal tear at the arch unable to be resected by hemiarch replacement, or dissection of the arch branches with malperfusion.  相似文献
