Purpose: Spontaneous isolated dissection of the celiac artery (SID-CA) and superior mesenteric artery (SID-SMA) are rare vascular diseases with similar presentation, yet comparative studies have not been reported. In this study, we compared their characteristics with the aim of providing insights into their etiology. Materials and Methods: Patients diagnosed with symptomatic SID-CA and SID-SMA between July 2009 and December 2018 were included. Demographics, clinical presentation, radiologic findings, treatment strategies, and outcomes were analyzed. Results: Twenty-one patients with SID-CA and 40 patients with SID-SMA were compared. Demographics and initial abdominal pain characteristics were similar, but pain severity was significantly higher and associated mean fasting time was significantly longer in patients with SID-CA than in those with SID-SMA (fasting time 3.2 vs 2.1 days, P= 0.001). Most patients were successfully treated conservatively without recurrent pain or aneurysmal dilatation, but 33.3% patients with SID-CA and 17.5% with SID-SMA required endovascular intervention. More favorable remodeling in terms of dissection regression on follow-up computed tomography was found after stenting, where patients with SID-CA showed better remodeling than those with SID-SMA. The overall median follow-up period was 22-31 months, while for patients with stent insertion, it was 55-77 months, and no stent occlusions were found during this period. Conclusion: Patients with SID-CA presented with severer and longer- duration abdominal pain than those with SID-SMA. Stenting in both groups showed good long-term patency and favorable remodeling, with a higher regression rate for SID-CA. Based on our results, patients with SID-CA may benefit more from active endovascular intervention.

Objective: The purpose of this study was to evaluate the incidence of gonadal vein refluxes associated with lower-extremity varicose veins with Doppler ultrasonography (DUS). Method: A total of 6279 patients with venous disease-related symptoms of the lower extremity were evaluated with DUS in the vascular lab. Gonadal vein reflux using abdominal ultrasound was further evaluated in patients with unusual varices, defined as varices in the inguinal, inner or upper thigh and the vulvar area without refluxes in the saphenofemoral junction (SPJ). Those patients who showed gonadal vein reflux were diagnosed as having pelvic-origin varicosity. Results: Unusual varices were found in a total of 237 patients (3.8%), and of these patients, pelvic-origin varicosity was discovered with transabdominal ultrasound in 156 (65.8%). A total of 66.7% (n = 38/57) of unusual varix patients with pelvic pain had gonadal vein reflux. The measurement of gonadal vein diameter was larger in ultrasonography than CT scans (8.835 vs. 8.81, p < 0.001). Two patients with severe symptoms but no obstructive venous diseases were treated with gonadal vein embolization. Conclusion: The incidence of pelvic-origin varicosities was 2.5% (n = 156/6279). However, more than half of the patients with unusual varices had gonadal vein reflux and 24.4% of these patients also presented with pelvic pain. The evaluation of pelvic-origin varicosities should be performed in patients who present with unusual forms of varices of the lower extremity.

Background and Objectives: The primary objective of this study was to determine the predictive factors of limb salvage and wound healing in patients presenting with diabetic foot ulcers (DFUs) following successful below-the-knee endovascular angioplasty. Materials and Methods: Between January 2014 and January 2019, we retrospectively analyzed the wound healing and limb salvage rates of 85 patients (88 limbs) who underwent infra-popliteal endovascular treatment (EVT) for DFUs. Numerous variables were explored, including age, sex, comorbidities, and the scores from three DFU grading systems (Wagner grade, University of Texas (UT) grade and stage, and Wound, Ischemia, and foot Infection (WIfI) stage). Univariate and multivariate Cox proportional hazards analyses were conducted to determine the associations between adverse events and these variables. Results: During follow-up, 44 wounds healed completely, 47 limb amputations (major, 25; minor, 22) were required, and 17 limbs needed reintervention for wound healing. Nine patients who received treatment died of cardiovascular and cerebrovascular diseases, pneumonia, and other causes. At 1, 3, 6, 9, and 12 months, total wound healing rates were 4.6%, 16.9%, 27.5%, 34.5%, and 64.5%, respectively. At 6 months, 1 year, 2 years, and 5 years, amputation-free survival rates were 77.6%, 72.4%, 63.3%, and 63.3%, respectively. In multivariate Cox analyses, the UT grade and stage were associated with increased wound non-healing, while the UT grade and Wagner grade were associated with increased major lower-extremity amputation rates. Importantly, the UT grade was the only simultaneous risk factor predicting both wound healing and limb salvage. Conclusions: Despite successful below-the-knee angioplasty, a significant proportion of patients experienced wound non-healing and major amputation. The UT grade may serve as a predictor for both wound healing and limb salvage outcomes.

Spinal cord ischemia after open repair of abdominal aortic aneurysm (AAA) is an unpredictable and devastating complication. We present a case report of a patient who developed paraplegia 6 hours after open repair of suprarenal AAA. A 74-yearold man presented with asymptomatic 5.5-cm suprarenal AAA, for which he underwent open repair under general anesthesia. The paraplegia was identified 6 hours after the operation. Postoperative magnetic resonance imaging showed T2 signal hyperintensity and swelling of the spinal cord, which were consistent findings with subacute spinal cord infarction. Although intravenous steroid was administered and lumbar cerebral spinal fluid drainage was instituted, his neurological outcome did not improve. He was discharged after vigorous rehabilitation but still has paraplegia and requires wheelchair for ambulation.
