A 78-year-old man presented at Eulji University Hospital due to an abdominal aortic aneurysm with maximum diameter of 52 mm, which had been increased from 45 mm over 6 months. He underwent embolization of the left internal iliac artery with vascular plug, prior to endovascular abdominal aortic repair with a bifurcated stent graft system. Unfortunately, the inserted vascular plug was maldeployed and protruded into left external iliac artery, and caused acute limb ischemia. Because revascularization of the occluded segment was failed, emergent hybrid approach with aorto-uni-iliac stent grafting and femoro-femoral bypass was done, successfully.

Marfan syndrome is a connective tissue disorder associated with aortic dissection, aneurysmal degeneration and rupture. These cardiovascular complications represent the main cause of mortality, therefore repair is indicated. We present a 35-year-old woman who experienced acute onset of chest pain. Her imaging revealed a chronic DeBakey type I dissection with aortic root dilation and descending thoracic aneurysmal degeneration. She underwent a Bentall procedure and endovascular exclusion of the descending thoracic aortic aneurysm. She was closely followed and 2 years later a computed tomography angiography (CTA) revealed the aneurysmal degeneration of the thoracoabominal aorta and bilateral iliac arteries. The patient underwent a composite reconstruction using multi-visceral branched and bifurcated Dacron grafts. At 5 years from her last surgery, a CTA revealed no new dissection or further aneurysmal degenerations. Aortic disease in Marfan patients is a complex clinical problem that may lead to secondary or tertiary aortic reconstructions; close follow-up is mandatory.

PURPOSE: Totally implantable venous access devices (TIVADs) are commonly used in pediatrics for the administration of chemotherapy, antibiotics, or parenteral nutrition. TIVADs can be implanted using various techniques, including surgical cutdown (SC) and percutaneous puncture (PP). Recently, percutaneous TIVAD became popular in adults, but studies comparing between PP and SC group in pediatric patients are rare. MATERIALS AND METHODS: Data were collected and analyzed retrospectively from 23 patients who underwent TIVAD at a single institution between January 2013 and December 2015. We examined the clinical characteristics, insertion techniques, and clinical outcome. We divided the patients into 2 groups and compared PP with ultrasonography and SC using the insertion technique. We compared success rate, procedural time, and the patency rate between the 2 groups. RESULTS: Eleven TIVADS were inserted using PP, and 12 TIVADs were inserted using SC. No statistically significant difference in characteristics was found between the 2 groups. The procedural time in the PP group was shorter than that in the SC group, but the difference was not statistically significant (P=0.685). During follow-up, 1 patient in the SC group had an occlusion, and 1 patient in the PP group had an infection. CONCLUSION: PP of the internal jugular vein with ultrasonography appears to be the method of choice for TIVAD insertion owing to its similar success rate in terms of implantation and complication rate to that in SC, with shorter procedural times in pediatric patients.

PURPOSE: To investigate the pattern of referral of patients with superior mesenteric artery embolism (SMAE) and its effect on outcomes, and to evaluate the risk factors for bowel infarction. MATERIALS AND METHODS: This retrospective study included 66 consecutive patients diagnosed with acute SMAE between January 2001 and June 2016. Appropriate diagnosis by the referring physician was defined if the referral letter indicated that acute mesenteric ischemia was suspected or had been diagnosed at the referral center. Surgical delay was defined as the interval between symptom onset and surgery for definitive treatment. RESULTS: Among 54 patients transferred from other centers, 26 patients (48.1%) were diagnosed appropriately by the referring physician. The rate of appropriate diagnosis was differed significantly by the use of computed tomography (CT) scan at referral center (25/35 with CT and 1/19 without CT, P=0.00). The surgical delay was significantly longer in patients without appropriate diagnosis compared with the patients with appropriate diagnosis (53.5±52.3 hours vs. 28.8±23.6 hours, P=0.04). Initially, 56 patients received surgical treatment with 31 underwent bowel resection due to infarction, 6 received conservative treatment, and the remaining 4 patients refused any treatment. The surgical delay, abdominal distension, tenderness, rebound tenderness, and level of C-reactive protein were associated with bowel infarction at initial operation. Overall in-hospital mortality was 32%. CONCLUSION: A high index of suspicion with appropriate diagnostic modality, such as CT scan is crucial in patients with SMAE for reducing surgical delay as a risk factor of bowel infarction.

PURPOSE: Ruptured abdominal aortic aneurysm (RAAA) is a rare, extremely dangerous condition. Previous studies have published preoperative, intraoperative, and postoperative data; however, there are not enough studies on the preoperative factors alone. Here we studied the preoperative predictors of 30-day mortality in patients with RAAA. MATERIALS AND METHODS: We conducted a retrospective, consecutive review of the medical records of 57 patients who received management for RAAA between February 2005 and December 2016. We analyzed the association between preoperative predictors and 30-day mortality in patients with RAAA. The initial systolic blood pressure (SBP) and hemoglobin level (HbL), which were proven as significant predictors by multivariate logistic regression analysis, were compared using receiver operating characteristic curves. RESULTS: Overall, early mortality was 29.8%. Results of logistic regression analysis found that 30-day mortality in patients with RAAA was associated with the initial SBP (odds ratio [OR], 0.922; 95% confidence interval [CI], 0.874–0.973; P=0.003) and initial HbL (OR, 0.513; 95% CI, 0.289–0.91; P=0.023). Area under the curves were 0.89 for the initial SBP and 0.78 for the initial HbL. The initial SBP with a cut-off value of 90 mmHg had a sensitivity of 85% and specificity of 88.2%. At a cut-off of 10.5, the sensitivity and specificity of HbL for death were 75% and 70.6%, respectively. CONCLUSION: The initial SBP and HbL are independent preoperative predictors of early mortality in patients with RAAA.

Cilostazol belongs to the new generation antiplatelet agents that have been introduced and studied regarding a potential role in cardiovascular disease prevention or treatment. Although data on peripheral artery disease are sufficient, and the drug has been recommended as first line treatment for intermittent claudication, it has not been approved nor recommended as far as cerebrovascular events are concerned. However, a great volume of randomized as well as pooled data has been published during the last years. Therefore, this review aims to describe the basic mechanisms of cilostazol’s action as well as to present all recent clinical data in order to conclude on whether official guidelines should be extended.

A 52-year-old man was admitted with an incidentally detected right renal artery aneurysm (RAA). Computed tomographic angiography with three-dimensional reconstruction revealed that the aneurysm was 2.2 cm in diameter and located at the renal hilum. We performed hand-assisted laparoscopic nephrectomy with ex vivo repair of the RAA and auto-transplantation with minimal elongation of Gibson incision. The operation and postoperative course were uneventful. At last follow-up, the patient was alive with a well-functioning auto-transplant. Hand-assisted laparoscopic nephrectomy and auto-transplantation is a useful treatment option for hilar RAA.

Endovascular abdominal aortic aneurysm (AAA) repair has been widely used for the treatment of AAA as a safe and efficient method, but endoleaks causing persistent expansion of aneurysm sac may cause aneurysmal rupture and death. Type 3 endoleak is rare but a predominant cause of late rupture. Type 3b endoleak can be misdiagnosed as type 2 endoleak, which is more frequent. Here we report two cases of type 3b endoleak mimicking type 2 endoleak, which were successfully treated by open surgery of partial explantation of the stent-graft and endoaneurysmal interposition graft replacement.

PURPOSE: To report experiences of the sandwich technique (ST) for preservation of pelvic flow during endovascular repair of complex aortic or aortoiliac aneurysms. MATERIALS AND METHODS: Eight patients underwent elective endovascular aneurysm repair (EVAR) using the ST between March 2013 and February 2017. The anatomic indications for the ST were complex aortoiliac aneurysms (5 cases), abdominal aortic aneurysms (AAA) with non-diseased short common iliac arteries (2 cases) and AAA with unilateral occluded iliac artery (1 case). The ST was performed through both femoral and brachial approach. Patient clinical and radiologic data were collected and analyzed. RESULTS: Eight patients (7 male; mean age, 73.4 years) were followed over a mean period of 277 days (range, 9–1,106 days). The technical success rate was 100%. The primary patency rate of the iliac stent-grafts was 88% (14/16 cases). One internal iliac and 1 external iliac stent-graft occlusion was observed during the early postoperative period. There was 1 gutter endoleak which disappeared spontaneously within 4 days, and there were 2 type II endoleaks: one treated by coil embolization after 13 months, and the other observed without treatment. There were no cases of sac growth or aneurysm-related deaths, and no cases of buttock claudication or impotence. CONCLUSION: The ST is a safe and feasible technique to preserve pelvic circulation during endovascular treatment of complex aortoiliac aneurysms. The need to expand the indications for complex EVARs with adjunctive procedures, such as the ST is highlighted in situations where branched/fenestrated device availability is limited.

PURPOSE: Use of a composite graft combining a polytetrafluoroethylene graft with an autogenous vein is an option for limb salvage in the absence of an adequate single segment vein graft. We aimed to investigate the results of infrainguinal bypass with a composite graft. MATERIALS AND METHODS: We retrospectively reviewed 11 infrainguinal arterial bypasses on 11 limbs which underwent surgery from March 2012 to November 2016. RESULTS: Critical limb ischemia was common (63.6%) indication of bypass surgery and most (90.9%) of the patients had history of failed previous treatment including endovascular treatment (36.4%) and bypass surgery (72.7%). At the 2 years after graft implantations, primary patency and amputation-free survival of below-knee bypasses using composite graft were 73% and 76%, respectively. CONCLUSION: Infrainguinal arterial bypasses with composite graft had an acceptable patency. In patients without other alternative conduits for revascularization, bypass with a composite graft can be an option.
