Objective
The natural history and parameters for successful nonoperative management of blunt traumatic aortic injuries (BTAIs) involving the descending aorta are poorly understood. We examined our experience with nonoperative BTAI treatment (anti-impulse, blood pressure) and evaluated for determinants of successful outcomes.Methods
We performed a review of our institutional prospective trauma registry database for all BTAI patients from 1999 to 2015. Computed tomography angiography was used to classify aortic injuries on the basis of severity: grade I, intimal tear; grade II, intramural hematoma; grade III, aortic pseudoaneurysm; and grade IV, free rupture. Grade IV injuries were excluded from nonoperative management. Baseline characteristics, clinical outcomes, and follow-up lesion resolution were compared within the medically managed cohort and between surgical and nonoperative groups using univariate and multivariable analysis.Results
Among 338 BTAI patients admitted between 1999 and 2015, 67 BTAI patients were managed nonoperatively; 26 (54%) had grade I BTAI, 22 (46%) had grade II, and 2 (4%) had grade III. Both grade III injuries required a late thoracic endovascular aortic repair after initial medical management and were excluded from analysis. In all, 48 were managed with initial medical therapy, and the remaining 19 died on admission or before definitive treatment. Among the 48 medically managed, the median age was 34 years, and 14 (29%) were female. Six of the 48 (12%) were transferred from other facilities. There was no significant difference in baseline characteristics or early outcomes between BTAI grades. Median injury resolution time was 39 days for grade I and 62 days for grade II (P = .03). Compared with a surgical cohort, BTAI grade and Abbreviated Injury Scale score for the chest were the only significant determinants of propensity to operate.Conclusions
Based on these limited data, it appears that patients with minimal aortic injuries (grades I and II) may be managed medically, with the majority resolving within 8 weeks. Minimal aortic injury is associated with low mortality and excellent intermediate-term outcomes. Further prospective studies are required to validate these findings. 相似文献2.

Objective
Technical progress in angioplasty expanded its application to very distal arterial lesions of the lower extremity. In cases of unsuccessful angioplasty tibiodistal bypass surgery may be required for limb salvage. We investigated the long-term outcome of this technique in patients with critical limb ischemia. The purpose of this study was to evaluate whether tibiodistal bypasses done after unsuccessful tibial angioplasty had inferior patency, limb salvage, or survival rates compared with primary tibiodistal bypasses.Methods
This single-center, retrospective data analysis included all distal bypass procedures originating from a tibial artery. Primary study end points were primary patency, secondary patency, and limb salvage. Secondary end points included survival, wound healing, and systemic and local complications. Society for Vascular Surgery reporting standards were applied.Results
There were 61 tibiodistal vein bypasses for critical limb ischemia performed in 23 years. Indications for tibiodistal bypass was Rutherford category 5 in 41 cases (67%) and category 6 in 20 cases (33%). Procedures were allocated to group A (primary bypass; n = 28) and group B (bypass after unsuccessful tibial angioplasty; n = 33). Primary patency was 55% versus 53% at 1 year and 47% versus 44% at 3 years (P = .58). Secondary patency was 59% versus 64% at 1 year and 52% versus 55% at 3 years (P = .36). Limb salvage was 96% versus 90% at 1 year and 91% versus 85% at 3 years (P = .44). Overall survival rates were 91% versus 97% at 1 year and 85% versus 92% at 3 years (P = .76). The median follow-up was 4.0 years in group A and 4.9 years in group B. In multivariate analyses for loss of primary patency and limb loss, no significant predictors could be identified.Conclusions
This study showed that tibiodistal vein bypass is a feasible, efficient, and safe technique in patients with critical limb ischemia. It provides acceptable primary and secondary patency rates to prevent major amputation and ensure survival. Previous unsuccessful tibial angioplasty had no significant impact on tibiodistal vein bypass outcome. This technique should be part of the armamentarium of vascular surgeons. 相似文献3.

Introduction
In the assessment of hand and upper limb function, grip strength is of the major importance. The measurement by dynamometers has been established.Purpose of the Study
In this study, the effect of a simulated ulnar nerve lesion on different grip force measurements was evaluated.Methods
In 25 healthy volunteers, grip force measurement was done by the JAMAR dynamometer (Fabrication Enterprises Inc, Irvington, NY) for power grip and by a pinch strength dynamometer for tip pinch strength, tripod grip, and key pinch strength.Study Design
A within-subject research design was used in this prospective study. Each subject served as the control by preinjection measurements of grip and pinch strength. Subsequent measurements after ulnar nerve block were used to examine within-subject change.Results
In power grip, there was a significant reduction of maximum grip force of 26.9% with ulnar nerve block compared with grip force without block (P < .0001). Larger reductions in pinch strength were observed with block: 57.5% in tip pinch strength (P < .0001), 61.0% in tripod grip (P < .0001), and 58.3% in key pinch strength (P < .0001).Discussion
The effect of the distal ulnar nerve block on grip and pinch force could be confirmed. However, the assessment of other dimensions of hand strength as tip pinch, tripod pinch and key pinch had more relevance in demonstrating hand strength changes resulting from an distal ulnar nerve lesion.Conclusions
The measurement of tip pinch, tripod grip and key pinch can improve the follow-up in hand rehabilitation.Level of Evidence

Objective
Use of autologous veins as peripheral bypass graft may become critical in the presence of significant varicose degeneration of the harvested vein. External support of such dilated veins with standard polytetrafluoroethylene (PTFE) prostheses was recommended as an option to use these veins for peripheral bypass. A single-center experience with this technique regarding long-term graft function, secondary reinterventions, and potential graft degeneration is presented.Methods
Between January 1995 and January 2006, there were 54 patients with varicose veins who underwent 57 consecutive infrainguinal vein bypass operations with PTFE reinforcement in 57 limbs. Indications for surgery consisted of disabling claudication (5), chronic critical ischemia (40), popliteal aneurysm (11), and acute ischemia (1). Grafts were observed with duplex ultrasound scan supplemented by additional angiography in case of recurrent ischemia, with prospective documentation of follow-up data in a computerized vascular database. Graft patency, limb salvage, and possible degeneration of the vein grafts were retrospectively analyzed.Results
Mean follow-up was 79 months (range, 1-219 months). The 30-day mortality was 2%. Secondary procedures to maintain or to restore bypass patency were necessary in 12 grafts (21%). Primary, primary assisted, and secondary patency rates were 54%, 73%, and 73% after 5 years for all bypasses, with a limb salvage rate for limbs operated on for chronic critical or acute ischemia of 83%. Significant stenosis of a reinforced vein segment was detected in one case after 56 months, with subsequent replacement of the vein graft with a biologic vascular prosthesis.Conclusions
Good late graft patency and limb salvage combined with a low rate of late vein graft degeneration justify the use of external PTFE reinforcement of varicose vein segments in infrainguinal bypass surgery. 相似文献5.
Introduction
The purpose of this study was to determine if there are clinical features that raise suspicion for parathyroid hyperplasia.Materials & methods
We retrospectively reviewed patients with primary hyperparathyroidism who underwent parathyroidectomy from 1991 to 2017, analyzing demographics, calcium and PTH, and localizing studies for patients with hyperplasia and single adenoma.Results
549 patients underwent parathyroidectomy: 464 (85%) with adenoma, 44 (8%) with double adenoma, 38 (7%) with hyperplasia, and 3 (1%) with cancer. Compared to patients with a single adenoma, patients with hyperplasia were more likely to have negative sestamibi, ultrasound or both exams (92% vs 6%, p < 0.001; 96% vs 4%, p < 0.001; and 91% vs 2%, p < 0.001) and lower gland weights (619 ± 1067 mg vs. 1466 ± 1899 mg, p < 0.001).Conclusion
Parathyroid hyperplasia should be suspected in patients with lower gland weights and negative imaging. 相似文献6.

Objective
The neutrophil-to-lymphocyte ratio (NLR) has been used as a surrogate marker of systemic inflammation. We sought to investigate the association between NLR and wound healing in diabetic wounds.Methods
The outcomes of 120 diabetic foot ulcers in 101 patients referred from August 2011 to December 2014 were examined retrospectively. Demographic, patient-specific, and wound-specific variables as well as NLR at baseline visit were assessed. Outcomes were classified as ulcer healing, minor amputation, major amputation, and chronic ulcer.Results
The subjects' mean age was 59.4 ± 13.0 years, and 67 (66%) were male. Final outcome was complete healing in 24 ulcers (20%), minor amputation in 58 (48%) and major amputation in 16 (13%), and 22 chronic ulcers (18%) at the last follow-up (median follow-up time, 6.8 months). In multivariate analysis, higher NLR (odds ratio, 13.61; P = .01) was associated with higher odds of nonhealing.Conclusions
NLR can predict odds of complete healing in diabetic foot ulcers independent of wound infection and other factors. 相似文献7.

Objective
The position of endovascular treatment in the algorithm of popliteal artery aneurysm (PAA) repair is still a matter of debate. Although several studies have described results similar to those of open surgery, follow-up of the endovascular group has been relatively short so far. The aim of this study was to describe the long-term outcome of endovascular repair of PAA with endografts.Methods
All patients with a PAA treated with an expanded polytetrafluoroethylene stent graft between June 1998 and November 2014 in a tertiary referral center were prospectively gathered in a database and retrospectively analyzed. The primary end point of this study was primary patency. Secondary end points included primary assisted and secondary patency, survival of the patient, stent fractures, secondary interventions, and limb loss.Results
A total of 75 PAAs were treated in 64 patients with a mean age of 68.1 ± 9.4 years. Unilateral PAA was present in 39 patients (61%) and bilateral PAAs in 25 patients (39%), of which 11 (17%) were treated bilaterally. Median follow-up was 68 months (range, 2-187 months). Primary patency at 1 year, 5 years, and 10 years was 84%, 60%, and 51%, respectively; primary assisted patency, 84%, 65%, and 57%; and secondary patency, 89%, 71%, and 60%. Stent fractures occurred in 28% of the cases (n = 21) in a median follow-up time of 47 months (range, 14-187 months). One-third of the fractures were associated with an occlusion that mainly presented with claudication, and only one was associated with acute ischemia. Reinterventions were performed in 12 cases (16%) during a median follow-up of 14 months (range, 1-47 months). The reintervention-free survival after 1 year, 5 years, and 10 years was 93%, 79%, and 79%, respectively. No major amputations were performed. The overall survival rate after 5 years and 10 years was 78% and 46%, respectively.Conclusions
Endovascular repair has established a definitive role in the treatment protocol for PAAs. It is associated with acceptable long-term patency rates. Stent fractures occurred in almost one-third of cases but never led to limb loss. Future developments should focus on the design of more dedicated and durable stents for this specific indication. 相似文献8.
Objective
To establish the long term outcomes of risk stratified management of differentiated thyroid cancer (DTC).Background
Guidelines for management of DTC lack a strong evidence base and expose patients to overtreatment. This prospective study of patients diagnosed with DTC between 1977 and 2012 describes the long term outcomes of a conservative risk stratified (AMES) management policy.Methods
Outcomes were analysed around patient and tumour characteristics, primary intervention (surgery ± radioiodine (RAI)), in terms of mortality, recurrence and reintervention.Results
Median follow-up in 348 patients was 14 years: mean age 48 (range 10–91) years, 257 (73.9%) female, 222 (68.3%) papillary cancer, tumour size 3.4 ± 2.0 cm (mean ± SD). 89 (25.6%) AMES high risk, 116 (33.3%) TNM stage III/IV and 16 (4.6%) had distant metastases. Primary surgery comprised lobectomy in 189 (54.3%): 11 (5.8%) patients had subsequent completion total thyroidectomy with cancer present in five. Primary nodal surgery was performed in 142 (40.8%) patients. 35 (13.5%) low and 43 (48.3%) high risk patients received RAI following initial surgery. Overall disease specific survival (DSS) was 92.1% at 10 years and 90.7% at 20 years. DSS at 20 years was 99.2% in low risk cases. AMES risk scoring predicted both survival and recurrence. Patients receiving RAI and AMES high risk were significantly associated with increased risk of death and recurrence.Conclusions
Routine total thyroidectomy and RAI are not justifiable for low risk DTC. Treatment should be tailored to risk and AMES risk stratification remains a simple reliable clinical tool. 相似文献9.

Objective
This study investigated the influence of the aortic bifurcation anatomy on the endovascular treatment of abdominal aortic aneurysms using Excluder (W. L. Gore & Associates, Flagstaff, Ariz) bifurcated stent grafts.Methods
This was a retrospective single-center study of patients treated with the Excluder stent graft. Analysis included anatomical factors of the aortic bifurcation (aortic bifurcation diameter [ABD], calcification, thrombus), characteristics of the stent graft limbs (sum of stent graft limbs diameters [SLD]), and the SLD/ABD ratio. Narrow bifurcation was defined as ABD <20 mm. Primary outcomes were intraoperative stenosis, need for additional intraoperative measures, limb stenosis, and occlusion during follow-up.Results
The study included 232 patients. Mean ABD was 24.6 ± 6 mm, with 53 patients (23%) presenting with narrow bifurcation (range, 12.5-19.5 mm). Median SLD in these patients was 28 mm, and the SLD/ABD ratio was 1.64. Calcification involving >50% of the bifurcation circumference was present in 32% of the patients, with 17% presenting thrombus in this area. Of 53 patients with narrow bifurcation, intraoperative stenosis >50% occurred in three (5.7%), which required adjunctive treatment. Computed tomography at 1 month showed limb stenosis >50% in nine patients (17%). No limb occlusions were recorded with a median follow-up of 34 months. Multivariate analysis of the overall series showed a higher risk of limb stenosis on the computed tomography at 1 month in patients with peripheral artery disease (hazard ratio [HR], 5.3; 95% confidence interval [CI], 1.2-24.4; P = .032), narrow bifurcation (HR, 5.7; 95% CI, 2-15.8; P = .001), higher SLD/ABD ratio (HR, 29.3; 95% CI, 4-215.2; P = .001), and calcium >50% (HR, 3; 95% CI, 1.1-8; P = .03), and lower in bifurcations with thrombus (HR, 0.3; 95% CI, 0.1-0.8; P = .017).Conclusions
Abdominal aortic aneurysms with narrow bifurcation can be treated with the bifurcated Excluder device without additional adjunctive measures. The presence of limb stenosis during follow-up is not associated with occlusion. Long-term follow-up studies are needed to confirm these results. 相似文献10.

Objective
The subintimal arterial flossing with antegrade-retrograde intervention technique has been used to overcome antegrade recanalization failures for peripheral lower limb arterial occlusive disease. There are few outcomes published for this technique and we sought to evaluate outcomes at our institution over a 7-year period.Methods
A retrospective review was performed of all subintimal arterial flossing with antegrade-retrograde intervention procedures of infrainguinal occlusive disease from 2009 to 2016. Retrograde and antegrade accesses were combined when occlusions could not be crossed from the antegrade direction. Baseline patient characteristics, procedures, procedure time, fluoroscopy time, contrast used, and radiation dose were collected. Posterior tibial waveforms, ankle-brachial index, limb salvage, vessel patency, and the presence of symptoms were assessed at follow-up.Results
Treatment was performed in 52 limbs in 52 patients (35 men and 17 women; mean age, 77.62 ± 11.61 years) with critical limb ischemia and no appropriate venous conduit for surgical bypass. Among the cohort, 63.5% were diabetics, 98% had hypertension, 53.8% had a prior myocardial infarction, and 36.5% end-stage renal disease. The average Rutherford Category before the intervention was 5.08 ± 1.01. Retrograde pedal access was most commonly obtained in the anterior tibial artery/dorsalis pedis (55.7%), followed by the posterior tibial artery (40.3%). The technical success rate was 63.5% (33/52); adjunctive stenting was needed in 19 (36.5%) to optimize results. Preprocedural ankle-brachial index score was 0.54 ± 0.25, which improved after the procedure to an ankle-brachial index score of 0.77 ± 0.25. The primary patency rates at 3 and 6 months were 65% and 60%, respectively. The limb salvage rate at a mean follow-up of 5.4 months was 78.8%. There were 5 complications; 4 were hematomas managed conservatively and 1 was a major retroperitoneal bleed resulting in patient death.Conclusions
Retrograde pedal access is a viable revascularization technique for achieving limb salvage in patients with critical limb ischemia with acceptable patency for limb-threatening ischemia. This technique expands revascularization options after failed conventional endovascular antegrade approaches. 相似文献11.

Background
There is a decreasing institutional percentage of surgical resident recipients of The Arnold P. Gold Humanism and Excellence in Teaching Award over time. The hypothesis was that this trend was a national phenomenon.Methods
This was a retrospective study from 2004 - 2015, utilizing data from the Arnold P. Gold Foundation. Multiple regression was performed using the estimated ratio of eligible surgical to non-surgical residents and the year as explanatory variables, utilizing an α = 0.05.Results
The percentage of surgical award winners was lower in the second study half compared to the first half (40.2% vs. 47.2%) (p = 0.02). Multiple regression showed that when controlling for the number of eligible residents, the number of resident awardees decreased over time (p = 0.01).Conclusion
There is a clear national trend that surgical residents are receiving the Arnold P. Gold Humanism and Excellence in Teaching Award less over time. 相似文献12.
Background
The integration of general and endocrine surgery was studied as a potential career model for fellowship trained general surgeons.Methods
Case logs collected from 1991–2016 and academic milestones were examined for a single general surgeon with a focused interest in endocrine surgery. Operations were categorized using CPT codes and the 2017 ACGME “Major Case Categories” and there frequencies were determined.Results
10,324 operations were performed on 8209 patients. 412.9 ± 84.9 operations were performed yearly including 279.3 ± 42.7 general and 133.7 ± 65.5 endocrine operations. A high-volume endocrine surgery practice and a rank of tenured professor were achieved by years 11 and 13, respectively. At year 25, the frequency of endocrine operations exceeded general surgery operations.Conclusion
Maintaining a foundation in broad-based general surgery with a specialty focus is a sustainable career model. Residents and fellows can use the model to help plan their careers with realistic expectations. 相似文献13.

Objective
The hybrid procedure of femoral endarterectomy and iliac artery stenting (FEIS) has been used as an alternative to traditional open surgical repair of iliofemoral arterial occlusive disease, but whether the severity of the iliac disease component affects long-term results is not well understood.Methods
This was a retrospective cohort study of patients undergoing FEIS at Geisinger Health System from January 1, 2004, through December 31, 2013, for the treatment of symptomatic iliofemoral atherosclerotic occlusive disease. The cohort was stratified according to the severity of the iliac occlusive disease component into patients with mild iliac disease (group 1) and patients with severe iliac disease (group 2).Results
Between January 1, 2004, and December 31, 2013, 99 patients underwent 111 total FEIS procedures. The mean age of the cohort was 67.4 years. Men composed 61% of patients. Indications for surgery were claudication (41%), ischemic rest pain (36%), and tissue loss (23%). At 5 years of follow-up, there was no difference in primary patency (73% in group 1 vs 68% in group 2 [P = .67]) and limb salvage (90% in group 1 vs 92% in group 2 [P = .51]). There was a trend toward higher overall mortality in group 2 patients vs group 1 patients (53% vs 81%; P = .08), but this did not reach statistical significance. Univariate analysis did not identify any device-related or anatomic factors predictive of patency.Conclusions
When combined iliofemoral arterial occlusive disease is treated with FEIS, the severity of the iliac disease component does not affect long-term patency or limb salvage. 相似文献14.
Background
Training in ultrasound is variable among residents and practicing traumatologists. Focused Assessment with Sonography in Trauma (FAST) may be underused in non-urbanized areas, possibly due to lack of training.Methods
State trauma registry data from January 2014–June 2016 were reviewed for FAST results. Trauma practitioners were surveyed querying training, confidence, and obstacles to performing FAST.Results
12,855 records revealed highest FAST use at the urban Level II center (39%, p < 0.0001). Despite similar injury patterns, non-urban/Level III centers' frequency of FAST was only 1–28%. 39 practitioners were surveyed, those with training (54%) were more likely to use FAST (p < 0.05). 61% of practitioners outside the Level II center cited lack of confidence in their ability to perform FAST as the primary reason for omitting the exam.Conclusions
FAST is relatively underused in non-urbanized areas of the state. Lack of confidence in ability to perform FAST was cited as the primary barrier. 相似文献15.

Objective
To compare continuous infusion preperitoneal wound catheters (CPA) versus continuous epidural analgesia (CEA) after elective colorectal surgery.Methods
An open-label equivalence trial randomizing patients to CPA or CEA. Primary outcomes were postoperative pain as determined by numeric pain scores and supplemental narcotic analgesia requirements. Secondary outcomes included incidence of complications and patient health status measured with the SF-36 Health Survey (Acute Form).Results
98 patients were randomized [CPA (N = 50, 51.0%); CEA (N = 48, 49.0%)]. 90 patients were included [ CPA 46 (51.1%); CEA 44 (48.9%)]. Pain scores were significantly higher in the CPA group in the PACU (p = 0.04) and on the day of surgery (p < 0.01) as well as supplemental narcotic requirements on POD 0 (p = 0.02). No significant differences were noted in postoperative complications between groups, aggregate SF-36 scores and SF-36 subscale scores.Conclusions
Continuous epidural analgesia provided superior pain control following colorectal surgery in the PACU and on the day of surgery. The secondary endpoints of return of bowel function, length of stay, and adjusted SF-36 were not affected by choice of peri-operative pain control. 相似文献16.

Background
Dexamethasone adds a unique challenge to glycemic control, and it may complicate patient care if there is an association between intra-operative dexamethasone and blood glucose levels.Methods
We analyzed 396 diabetic patients who underwent general anesthesia for various surgical procedures and were hospitalized post-operatively for at least 24 h between January 2015 and June 2016. Patients were classified into two groups-those who received dexamethasone intra-operatively and those who did not. The groups were analyzed for blood glucose changes during and following their procedure.Results
A total of 396 diabetic patients (152 (38.8%) dexamethasone group; 244 (62.2%) control) were included. The dexamethasone group had significantly lower preoperative blood glucose (135.5 mmol/L) compared to the control group (144.4 mmol/L) (p = 0.04) and significantly lower proportion of patients who had received insulin during surgery (14.9%) compared to the control group (23.4%) (p = 0.04). Overall, glucose levels declined from pre-op to post-op day 1 by 9.6 (62.9) (p = 0.007).Conclusion
Diabetic patients receiving dexamethasone for control of post-operative nausea during surgery are at greater risk for increasing blood glucose levels and difficult glycemic control during and after surgery compared to patients receiving other medications to control post-operative nausea. 相似文献17.

Study Design
Case series (longitudinal).Introduction
Only few reports concerning the efficacy of commonly used strategies for preventing upper limb occupational disorders associated with prolonged typing exist.Purpose of the Study
We aimed to investigate whether the duration of typing and the use of 2 strategies (hand rest and wrist support) changes muscle physiological response and therefore the electromyography records.Methods
We enrolled 25 volunteers, who were unfamiliar with the task and did not have musculoskeletal disorders. The subjects underwent 3 prolonged typing protocols to investigate the efficacy of the 2 adopted strategies in reducing the trapezius, biceps brachii, and extensor digitorum communis fatigue.Results
Typing for 1 hour induced muscular fatigue (60%-67% of the subjects). The extensor digitorum communis muscle exhibited the highest percentage of fatigue (72%-84%) after 1 and 4 hours of typing (1 hour, P = .04; 4 hours, P = .02). Fatigue levels in this muscle were significantly reduced (24%) with the use of pause typing (4 hours, P = .045), whereas biceps brachii muscle fatigue was reduced (32%) only with the use of wrist supports (P = .02, after 4 hours). Trapezius muscle fatigue was unaffected by the tested occupational strategies (1 hour, P = .62; 4 hours, P = .85).Discussion
Despite presenting an overall tendency for fatigue detected during the application of the protocols, the assessed muscles exhibited different behavior patterns, depending on both the preventive strategy applied and the muscle mechanical role during the task.Conclusion
Hand rest and wrist support can successfully reduce muscle fatigue in specific upper limb muscles during prolonged typing, leading to a muscle-selective reduction in the occurrence of fatigue and thus provide direct evidence that they may prevent work-related musculoskeletal disorders.Level of Evidence

Objective
Acute limb ischemia (ALI) is the cause of significant morbidity and mortality. Although ALI after cardiac surgery is associated with high rates of morbidity and mortality, there are no robust, controlled analyses of the risk factors and outcomes of ALI in this setting. We aimed to identify risk factors for and to delineate outcomes after ALI in patients undergoing cardiac surgery.Methods
We performed a retrospective review of prospectively collected data on patients undergoing cardiac surgery at our institution between 2002 and 2012.Results
Between 2002 and 2012, there were 11,343 patients who underwent major open cardiac surgery, with 156 cases of ALI for an incidence of 1.4%. In a multivariable model, significant risk factors for ALI included body surface area (odds ratio [OR], 0.41; 95% confidence interval [CI], 0.18-0.92), current smoking status (OR, 2.2; 95% CI, 1.3-3.7), peripheral arterial disease (OR, 2.5; 95% CI, 1.6-3.7), nonelective operative status (OR, 1.9-5.0; 95% CI, 1.2-19.7), use of extracorporeal membrane oxygenation (OR, 5.6; 95% CI, 2.5-11.6) or intra-aortic balloon pump (OR, 4.7; 95% CI, 2.9-7.5), and valve operation (OR, 2.1; 95% CI, 1.1-4.0). There were 105 (67%) patients who developed ALI who required an operation, and 27 (17%) required an amputation on the index admission. ALI was associated with a significant reduction in long-term survival (hazard ratio, 3.72; 95% CI, 2.97-4.65; P < .0001).Conclusions
ALI is associated with significant morbidity and mortality, and it is also associated with reduced long-term survival.
