Purpose
The aim of this investigation was to suggest practices to improve the delivery of work-integrated learning (WIL) in radiography training in South Africa (SA).Methods
An extensive survey was conducted among all universities in SA involved in the training of radiography students, to investigate the current delivery of WIL. Data were collected by means of quantitative questionnaires with open-ended qualitative components. The questionnaire was distributed to lecturers (n = 32), clinical supervisors (n = 44) and final-year students in Radiography (n = 146).Results
The quantitative (closed questions) and qualitative (open-ended comments) findings from the stakeholders with regard to the improvement of practice in the delivery of WIL in radiography training are presented in this article. The main themes discussed relate to curriculum design for WIL, teaching/learning of WIL, assessment of WIL and management and coordination of WIL.Conclusion
WIL is a powerful pedagogy if implemented and managed correctly. The results from this study may enable lecturers in radiography programmes in SA to improve the delivery of WIL in the training of high quality, employable graduates. 相似文献2.

Purpose
To address the feasibility of infusion of yttrium-90 (90Y) glass microspheres directly through the right inferior phrenic artery (RIPA).Materials and Methods
From November 2015 to May 2017, 20 patients underwent 90Y radioembolization through the RIPA. When the systemic-to-pulmonary shunt was demonstrated on C-arm computed tomography (CT) of the RIPA, prophylactic embolization by polyvinyl alcohol (PVA) particles was performed prior to infusion of 90Y glass microspheres. Follow-up CT scans were retrospectively reviewed for pulmonary complications. Tumor response was determined by the modified Response Evaluation Criteria in Solid Tumors.Results
Nine (45%) patients had systemic-to-pulmonary shunts on C-arm CT images of the RIPA. The feeder of the systemic-to-pulmonary shunt was the azygoesophageal branch (n = 7) and the anterior branch (n = 2). The mean activity of 90Y glass microspheres infused into the RIPA was 0.49 GBq (range, 0.19–1.55 GBq). No patient had symptomatic radiation pneumonitis or cutaneous complications during follow-up. Seven patients had focal atelectasis (n = 5), focal ground-glass opacity (n = 2), and/or a small amount of pleural effusion (n = 2) on follow-up image. Best tumor response fed by the RIPA was complete response (n = 4), partial response (n = 9), stable disease (n = 2), progressive disease (n = 4), and unevaluable (n = 1).Conclusion
The administration of 90Y glass microspheres through the RIPA may be safe after embolization of a systemic-to-pulmonary shunt identified on C-arm CT. 相似文献3.

Purpose
To assess safety, efficacy, and long-term outcome of repeat bronchial artery embolization (BAE) for recurrent hemoptysis.Materials and Methods
This was a retrospective study of patients referred for repeat BAE to manage recurrent hemoptysis after initial successful embolization. BAE was performed in 223 patients; 36 (16.1%) of these patients underwent 59 repeat BAE procedures because of recurring symptoms. The most frequent underlying lung diseases were bronchiectasis (n = 8; 22%), cystic fibrosis (n = 7; 19%), and idiopathic hemoptysis (n = 7; 19%).Results
Most patients (64%) underwent 2 embolization procedures owing to vessel recanalization (71%) as the most frequent pathophysiologic mechanism of recurrent hemoptysis. No serious adverse events requiring prolonged hospital stay were noted. Risk for relapse of hemoptysis was significantly lower for bronchiectasis compared with other chronic infections (P = .0022) and cystic fibrosis (P = .0004). Overall survival after 3-year and 5-year follow-up was 92% and 84%, respectively.Conclusions
Repeat BAE for recurrent hemoptysis after initial successful BAE is safe and efficacious, especially in patients with bronchiectasis as the underlying lung disease. 相似文献4.

Purpose
To compare the feasibility and safety of mono-port catheter system and dual-port catheter system for advanced hepatocellular carcinoma (HCC) in patients with anatomic hepatic artery variation and portal vein tumor thrombosis.Materials and Methods
This retrospective study consisted of 22 patients with infiltrative or multiple HCC with unilateral or bilateral portal vein thrombosis who had hepatic artery variation. A mono-port or dual-port catheter system was determined according to the degree of blood supply to the entire tumor through the common hepatic and variant hepatic arteries. Intrahepatic perfusion pattern, hepatic toxicity, and tumor response were investigated on computed tomography, medical records, and follow-up imaging study.Results
The most common hepatic arterial variation was replaced right hepatic artery arising from the superior mesenteric artery (n = 16), followed by replaced left hepatic artery (n = 5) and replaced right posterior segmental artery (n = 1). Twelve patients were treated with mono-port catheter system, and 10 patients were treated with dual-port catheter system. All 10 patients in the dual-port group showed homogeneous distribution of contrast material in the entire liver after port implantation, and 6 patients (50%, n = 6/12) in the mono-port group showed heterogeneous distribution (P = .018). The objective tumor response rates (P = .361) were 18.2% and 40%, and the disease control rates (P = .395) were 36.4% and 60% in the mono-port and dual-port groups, respectively.Conclusions
The dual-port catheter system is a safe and effective technique that allows the even distribution of hepatic arterial infusion chemotherapy without hemodynamic modification of anatomic variation in the hepatic arteries. 相似文献5.

Purpose
To assess the frequency and potential predictors of prostatic central gland tissue detachment (CGD), an enucleation-like reaction that sporadically occurred in a randomized controlled trial assessing efficacy and safety of prostatic artery embolization (PAE).Materials and Methods
Trial data were analyzed to identify patients with CGD after PAE. Clinical parameters, MR imaging findings, technical details of PAE, and periinterventional data were compared between patients with and without CGD to identify parameters for prediction, induction, or early detection of CGD after PAE.Results
CGD occurred after PAE in 3 of 48 patients (6.3%); these cases had good functional outcomes, but CGD was associated with increased risk of ejaculatory dysfunction and occurrence of complications. Frequency of preoperative transurethral bladder catheterization (100% vs 13.3%; P = .005), central gland index (mean ± standard deviation, 0.86 ± 0.02 vs 0.69 ± 0.14; P < .001), amount of particles applied (1.93 mL ± 0.12 vs 0.96 mL ± 0.36; P < .001), maximum early postoperative pain score (7.33 ± 2.08 vs 1.89 ± 2.40; P = .009), and blood C-reactive protein (CRP) levels after 48 hours (69.0 vs 18.58 mg/dL; P = .045) and 1 week (113.50 vs 5.16 mg/dL; P = .004) were significantly higher in cases of CGD.Conclusions
CGD is a rare reaction that might be triggered by prostatic zonal anatomy, embolization technique, and mechanical or inflammatory processes. It should be considered in patients with severe postoperative pain and high CRP levels who experience voiding dysfunction after PAE to avoid complications. Investigation of larger cohorts might further elucidate this tissue response. 相似文献6.

Purpose
To determine technical feasibility and results of stent-assisted coiling of visceral artery aneurysms (VAAs) with self-expandable LEO PLUS neurointerventional stent.Materials and Methods
In this retrospective study, 11 consecutive patients (mean age 61.9 y ± 8.9; range, 45–76 y) with VAAs (splenic, n = 3; common hepatic, n = 2; renal, n = 5; celiac, n = 1) treated with neurointerventional stents were included. MR angiography was evaluated for aneurysmal occlusion and patency of the parent arteries.Results
Technical success was 90.9%. A minor technical complication developed in 1 patient (9%), and thrombosis of the distal part of the stent was seen just after deployment in another patient, but it resolved after tirofiban injection. Complete occlusion was determined in all patients on MR angiography at 6-month follow-up.Conclusions
Self-expandable LEO PLUS neurointerventional stents could become a useful tool in the treatment of VAAs. Studies with larger groups of patients, including control groups, are needed to assess the true outcome of this treatment method. 相似文献7.

Purpose
To compare treatment with hepatic arterial infusion of chemotherapy (HAIC) in patients with advanced hepatocellular carcinoma (HCC) with both extrahepatic spread (EHS) and intrahepatic tumor and patients with intrahepatic tumor only.Materials and Methods
This single-center retrospective study comprised 116 patients with advanced HCC with both intrahepatic tumor and EHS (EHS group; n = 50) or with intrahepatic tumor only (non-EHS group; n = 66) treated with HAIC including oxaliplatin, fluorouracil, and leucovorin between June 2014 and July 2016. Overall survival (OS) and radiologic responses to treatment were determined and compared between the 2 groups.Results
Both the objective response rate and the clinical benefit rate were higher in the non-EHS group than in the EHS group (37.9% vs 16% objective response rate, P = .010; 81.8% vs 62% clinical benefit rate, P = .017). Median OS was not statistically different between the 2 groups (14.8 months vs 9.8 months, P = .068). Subgroup analysis of OS found that patients with lung metastases survived for a shorter time (OS 7 months) than patients with other metastatic sites (P = .003) and patients free of metastases (P = .001).Conclusions
HAIC is a potential treatment option for advanced HCC with limited extrahepatic metastases in a population with hepatitis B virus infection. 相似文献8.

Purpose
To determine success and complication rates of percutaneous transjejunal biliary access (PTJBA) in patients with bilioenteric anastomoses.Materials and Methods
In a single-center, retrospective study, 169 PTJBA procedures were performed over a 13.8-y period in 60 subjects (47 male; mean age, 54.5 y). Indications for biliary interventions were cholangitis (137 cases, 45 subjects) or hyperbilirubinemia (32 cases, 18 subjects). All patients had antecolic bilioenteric anastomoses without surgical fixation to the peritoneum (liver transplantation with hepaticojejunostomy, n = 37; hepatectomy with hepaticojejunostomy, n = 8; hepaticojejunostomy only, n = 12; pancreaticoduodenectomy, n = 3).Results
Initial PTJBA was successful in 140 cases (82.8%) in 35 subjects (58.3%). Twenty-one additional PTJBAs (12.4%) in 18 subjects (30.0%) were performed secondarily following a conventional transhepatic approach. Radiographic markers on the Roux-en-Y limb (P = .14, odds ratio [OR] = 2.98) or preprocedural imaging (P = .13, OR = 10.00) did not increase the odds of successful PTJBA. There were 7 major complications (4.3%) in 6 patients (10.0%) requiring hospitalization longer than 5 d, and 37 minor complications (23.0%) in 19 patients (31.7%). No procedure-related mortality was observed. Minor and major complication rates were not affected by time between bilioenteric anastomosis creation and PTJBA (P = .70, OR = 1.00; P = .62, OR = 1.00), longer dwell time of a transjejunal drain (P = .68, OR = 1.02; P = .49, OR = 0.71), or access size (P = .40, OR = 0.85; P = .23, OR = 0.59).Conclusions
PTJBA is a relatively safe technique with a high success rate in patients with bilioenteric loops that are not surgically fixed to the peritoneum. 相似文献9.

Purpose
To identify technical factors that significantly change prostatic artery embolization (PAE) technical outcomes and to derive and test technical outcome predictive models.Materials and Methods
Retrospective analysis of PAEs performed by 2 operators (OPs) was performed: OP1, between April 2014 and May 2017 (n = 150); OP2, between February 2017 and December 2017 (n = 67). Multivariate analysis with mixed-effects modeling was used to test significance and derive predictive models. Mean difference was used to analyze prediction accuracy.Results
Moderate versus none subjective iliac tortuosity grade (SITG) and the presence of internal iliac atherosclerosis (PIIAA) versus none were associated with the following respective technical outcome increases: procedure time (PT): 43% (P < .01), 16% (P < .01); fluoroscopy time (FT): 47% (P < .01), 25% (P < .01); contrast volume (CV): 25.6 mL (P < .001), 13.7 mL (P = .01); and dose area product (DAP) 52% (P < .01), 20% (P = 0.03). Prostatic artery origin left obturator versus left superior vesical was associated with a 24% (P = .01) DAP decrease. For every 1 cc that prostate volume increased, CV decreased on average by 0.1 mL (P = .05). For every 1-cm decrease in patient height and 1-kg increase in weight, DAP increased on average by 0.02% (P < .01) for each. Unilateral versus bilateral versus 3-vessel embolization resulted in a 16.3-mL CV decrease on average for each additional vessel embolized (P = .03). The mean absolute differences between predicted and measured technical outcome values were: PT: 16 minutes, FT: 7 minutes, CV: 25 mL, and DAP: 44 Gy·cm2.Conclusions
In this study, higher SITGs and PIIAA most likely contributed to higher technical outcomes when controlling for the 2 OPs. 相似文献10.

Purpose
To evaluate the effectiveness and durability of intra-arterial aneurysm sac embolization for the treatment of type Ia endoleak after endovascular aneurysm repair (EVAR).Materials and Methods
From February 2011 to December 2016, 22 patients underwent embolization of a type Ia endoleak after EVAR. Four patients (18%) were treated during the index EVAR and 18 (82%) in follow-up. Five patients (23%) were treated urgently and 17 (77%) electively. The embolization was performed with the use of liquid embolic agent, coils, and/or plugs. Adjunctive neck procedures were performed in 55% (n = 12) of the patients. The primary endpoint of this study was freedom from sac enlargement. Key secondary endpoints were technical success and freedom from endoleak-related reinterventions.Results
Technical success was 100%. The 30-day mortality was 5% (n = 1; acute coronary syndrome). At a mean follow-up of 15.4 months (range 0.1–65.4) the freedom from sac enlargement rate was 76% (16 out of 21). Reintervention-free survival rates at 6, 12, and 24 months were 80%, 68% and 68%, respectively.Conclusions
In patients with persistent type Ia endoleak the embolization of the aneurysm sac with or without adjunctive neck procedures can be safely performed, leading to acceptable clinical and radiologic outcomes. 相似文献11.

Purpose
To compare safety and efficacy of vascular plugs (VPs) and fibered platinum coils (FPCs) for embolization in pelvic congestion syndrome (PCS).Materials and Methods
A randomized, prospective, single-center study enrolled 100 women with PCS from January 2014 to January 2015. Patients were randomly assigned to 2 groups, and embolization was performed with FPCs (n = 50) or VPs (n = 50). Mean age of patients was 42.7 years ± 7.60, and mean visual analog scale (VAS) score for pelvic pain before treatment was 7.4 ± 7.60. Primary outcome (clinical success at 1 y using a VAS), number of devices, procedure and fluoroscopy times, radiation doses, costs, and complications were compared, and participants were followed at 1, 3, 6, and 12 months.Results
Clinical success and subjective improvement were not significantly different at 1-year follow-up (89.7% for FPCs vs 90.6% for VPs; P = .760). Mean number of devices per case was 18.2 ± 1.33 for FPCs and 4.1 ± 0.31 for VPs (P < .001). Three FPCs and 1 VP migrated to pulmonary vasculature approximately 3–6 months after the embolization procedure; all were retrieved without complications. The FPC group had a significantly longer fluoroscopy time (33.4 min ± 4.68 vs 19.5 min ± 6.14) and larger radiation dose (air kerma 948.0 mGy ± 248.45 vs 320.7 mGy ± 134.33) (all P < .001).Conclusions
Embolization for PCS resulted in pain relief in 90% of patients; clinical success was not affected by embolic device. VPs were associated with decreased fluoroscopy time and radiation dose. 相似文献12.

Purpose
To evaluate the safety and efficacy of bronchial artery embolization (BAE) in patients with primary lung cancer-related hemoptysis and to identify factors associated with hemoptysis-free survival.Methods
Data from 84 patients with primary lung cancer (non-small cell [n = 74] and small cell [n = 10]) who underwent BAE from 1997 to 2018 for the management of hemoptysis were retrospectively reviewed. Of these, 53 patients had stage IV lung cancer. The hemoptysis volume prior to initial BAE was trivial (blood-tinged sputum) in 21 patients, moderate (< 300 mL per 24 hours) in 34 patients, and massive (> 300 mL per 24 hours) in 29 patients.Results
Technical success, defined as the ability to selectively embolize the abnormal vessel, was achieved in 83 patients (98.8%), and clinical success was achieved in 69 (82.1%) patients. Polyvinyl alcohol particles were used to embolize in 51 patients, gelfoam in 15 patients, and gelfoam plus microcoils in 17 patients. Hemoptysis recurred in 20 patients (23.8%) during follow-up. The median hemoptysis-free survival and overall survival periods were both 61 days. In the clinical-success and clinical-failure groups, the median overall survival period was 99 and 9 days, respectively (P < .001). In multivariable analysis, massive hemoptysis (P = .012) and cavitary lung mass (P = .019) were predictive factors for shortened hemoptysis-free survival.Conclusions
BAE is a safe and effective approach to control hemoptysis, although the prognosis in primary lung cancer patients presenting with hemoptysis is generally poor. Massive hemoptysis and cavitary lung mass are significant predictors of shortened hemoptysis-free survival. 相似文献13.

Purpose
To determine if there is a correlation between intrahepatic tumor volume and future liver remnant (FLR) hypertrophy after portal vein embolization (PVE).Materials and Methods
Forty-four consecutive patients with hepatocellular carcinoma or metastatic colorectal cancer who underwent PVE from 2009 to 2017 and who had complete imaging follow-up were retrospectively reviewed. To maximize the accuracy of tumor volume measurements, 11 patients were excluded for having more than 5 intrahepatic tumors. Volumetric analyses of the patient livers before and after PVE, as well as pre-embolization intrahepatic tumor burden, were performed.Results
A significant inverse correlation was observed between tumor volume and FLR hypertrophy after PVE (Spearman ρ = -0.53, P = .002). Initial FLR volume was also inversely correlated with subsequent hypertrophy (P = .01). Fourteen patients received neoadjuvant chemotherapy 1 month prior to intervention. The number of chemotherapy cycles did not affect hypertrophy (P = .57). Patients with cirrhosis experienced less FLR hypertrophy than patients without cirrhosis (P = .02).Conclusions
Patients with large intrahepatic tumor burden may experience limited FLR hypertrophy. 相似文献14.

PURPOSE
Patients with large prostate glands are underrepresented in clinical trials incorporating brachytherapy due to concerns for excessive toxicity. We sought to compare health-related quality of life (HRQOL) outcomes between small (<60 cc) and large (≥60 cc) prostates treated with high-dose-rate brachytherapy (HDR-B).METHODS AND MATERIALS
One hundred thirty patients at Emory University were treated with HDR-B monotherapy (n = 75) or HDR-B in combination with external beam radiation therapy (n = 55). American Urologic Association Symptom Score (AUASS) and expanded prostate cancer index composite for clinical practice (EPIC-CP) scores were recorded. A linear mixed model was performed dichotomizing prostate volume (<60 and ≥ 60 cc) with AUASS, individual EPIC-CP domains (urinary incontinence, urinary irritation/obstruction [UIO], bowel function, sexual function, and vitality/hormonal function), and overall EPIC-CP HRQOL scores.Results
Median followup was 22.6 months (range 2.2–55.8). The median gland volume for the entire cohort (n = 130), <60 cc cohort (n = 104), and ≥60 cc cohort (n = 26) was 44 cc, 41.1 cc, and 68.0 cc, respectively. There were no baseline differences in HRQOL scores between cohorts. At 2 months, AUASS and UIO scores increased similarly between cohorts (AUASS p = 0.807; UIO p = 0.539), then decreased (longitudinal effect p < 0.001 and p = 0.005, respectively) to remain not significantly different at 12 months (AUASS p = 0.595; UIO p = 0.673). Overall, prostate volume was not significantly associated with change in AUASS (p = 0.403), urinary incontinence (p = 0.322), UIO symptoms (p = 0.779), bowel symptoms (p = 0.757), vitality/hormonal symptoms (p = 0.503), or overall HRQOL (p = 0.382).Conclusions
In appropriately selected patients, HDR-B appears well tolerated in patients with ≥60 cc prostate glands without an increase in patient-reported toxicity. Volume should not be a strict contraindication in those with adequate baseline function. 相似文献15.

Purpose
To evaluate the long-term results of and patient satisfaction with trapezius ports in breast cancer patients, as an alternative to chest ports.Patients and Methods
This retrospective study included all patients who underwent trapezius port placement from December 2007 to January 2017. Seventy female patients with breast cancer, with a mean age of 54 ± 9.9 years (range, 29–76 years), were included. Indications for trapezius implantation were bilateral breast surgery or unilateral breast surgery and contralateral breast involvement. Sixty-eight of 70 patients had long-term follow-up. A retrospective, questionnaire-based survey was conducted to assess satisfaction and the trapezius port’s effect on the daily life of the patient.Results
All implantations were technically successful. Total catheter service time for 68 patients was 65,952 days (2 patients were lost to follow-up). Mean catheter service time was 969.8 days (range 7–3,458 days; median 570 days; 95% confidence interval, 739–1199; standard deviation, 947.7). No immediate procedural complications occurred. Port complications developed in 4 patients (5.9%); port infection developed in 2 patients (0.03/1,000 days); skin dehiscence developed in 1 patient (0.02/1,000 days); and port malfunction developed in 1 patient (0.02/1,000 days). The overall infection rate was 2.9% (2/68). All patients (n = 44) or a close relative (n = 17) who were interviewed with a phone call reported satisfaction regarding their ports.Conclusions
Trapezius ports offer a safe and feasible option to patients with breast cancer who need an alternative site to chest ports. It is also associated with high overall patient satisfaction. 相似文献16.

Purpose
To investigate the current state of gender diversity among invited coordinators at the Society of Interventional Radiology (SIR) Annual Scientific Meeting and to compare the academic productivity of female interventional radiologists to that of invited male coordinators.Materials and Methods
Faculty rosters for the SIR Annual Scientific Meetings from 2015 to 2017 were stratified by gender to quantify female representation among those asked to lead and coordinate podium sessions. To quantify academic productivity and merit, H-index, publications, and authorship by females over a 6-year period (2012–2017) were statistically compared to that of recurring male faculty.Results
From 2015 to 2017, women held 7.1% (9/126), 4.3%, (8/188), and 13.7% (27/197) of the available coordinator positions for podium sessions, with no representation at the plenary sessions, and subject matter expertise was concentrated in economics and education. Academic productivity of the top quartile of published female interventional radiologists was statistically similar to that of the invited male faculty (H-index P = .722; total publications P = .689; and authorship P = .662).Conclusions
This study found that senior men dominate the SIR Annual Scientific Meeting, with few women leading or coordinating the podium sessions, despite their established academic track record. 相似文献17.

Purpose
To evaluate treatment outcomes with percutaneous cryoablation (PCA) based on renal cell carcinoma (RCC) histology.Methods and Materials
Patients treated with PCA for a solitary, sporadic stage T1a RCC from 2003 to 2016 were identified from a single institution’s renal ablation registry. Patients with multiple tumors, history of RCC, or genetic syndromes associated with RCC (n = 60); no specific RCC subtype determined from core biopsy (n = 66); RCC subtype other than clear-cell or papillary (n = 7); or less than 3 mo of follow-up imaging (n = 5) were excluded. In total, 173 patients met study inclusion criteria. Oncologic outcomes, clinical outcomes, and complications were evaluated based on tumor subtype.Results
Of the 173 patients who underwent PCA for a stage T1a RCC, 130 (75%) had clear-cell RCC (ccRCC) and 43 (25%) had papillary RCC (pRCC). Median tumor size was 2.9 cm (range, 1.3–4.0 cm). Technically successful cryoablation was achieved in all 173 patients. Local tumor recurrence developed in 6 patients with ccRCC (4.6%), new renal tumors developed in 1 patient (0.8%), and metastatic RCC developed in 1 patient (0.8%) who also had local tumor recurrence. No patients with pRCC showed local tumor recurrence, new renal tumors, or metastatic disease. The 5-year disease-free survival rate in patients with ccRCC was 88%, compared with 100% in patients with pRCC (P = .48). Nine patients (5.2%), all with ccRCC, experienced major complications (P = .11).Conclusions
Percutaneous ablation is a viable treatment option for patients with clinical stage T1a pRCC and ccRCC. Percutaneous ablation may be a very favorable treatment strategy particularly for pRCC. 相似文献19.

Purpose
To evaluate 30-day safety and efficacy of superselective embolization for arterial upper gastrointestinal bleeding (UGIB) using N-butyl cyanoacrylate (NBCA).Materials and Methods
This single-center retrospective 10-year study included 152 consecutive patients with UGIB (gastric, n = 74; duodenal, n = 78) who underwent embolization with NBCA for angiographically positive arterial bleeding. The primary endpoint was clinical success rate defined as achievement of hemostasis without rebleeding or UGIB-related mortality within 30 days after embolization. Mean systolic blood pressure and heart rate were 121.2 mm Hg ± 27.4 and 97.9 beats/minute ± 22.5; 31.1% of patients needed intravenous inotropes, and 36.6% had coagulopathy. The etiology of bleeding was ulcer (80.3%) or iatrogenic injury (19.7%). Statistical analysis was performed to identify predictive factors for outcomes.Results
Technical success rate was 100%. Clinical success, 1-month mortality, and major complication rates were 70.4%, 22.4%, and 0.7%. There were significant differences in the clinical success rates between gastric and duodenal bleeding (79.4% vs 62.2%; P = .025). The need for intravenous inotropes at the time of embolization was a significant negative predictive factor in both gastric (odds ratio [OR] = 0.091, P = .004) and duodenal (OR = 0.156, P = .002) bleeding. The use of a microcatheter with a smaller tip (2 F) was associated with better outcomes in duodenal bleeding (OR = 7.389, P = .005).Conclusions
Superselective embolization using NBCA is safe and effective for angiographically positive arterial UGIB. 相似文献20.
