A giant abdominal aortic aneurysm (AAA) renders surgical treatment much more difficult by deforming the proximal infrarenal aortic neck (shortened length and disturbed angulation), by altering the iliac arteries (marked tortuosity and aneurysmal dilatation), and by displacing abdominal organs. Because the retroperitoneal rupture of giant AAA makes the mesentery more elongated and deformed, compromising its blood flow and thus increasing the risk of mesenteric ischemia such as colon ischemia. We describe here the surgical repair of a large infrarenal AAA with a ruptured huge left common iliac artery aneurysm of 13.5 cm in diameter, accompanied by colostomy due to colon ischemia which occurred during the operation. We discuss the pathophysiology and preventive strategy of colon ischemia during ruptured giant AAA repair.

PURPOSE: Our study aims to evaluate to evaluate clinical outcomes after cephalic vein transposition (CVT) to the axilla in patients with brachiocephalic arteriovenous fistula (BC-AVF) and cephalic arch stenosis (CAS). MATERIALS AND METHODS: Hospital records of 13 patients (median age, 61 years; males, 54%) who received CVT to the proximal basilic/axillary vein due to either dysfunction (n=2) or thrombosis (n=11) between January 2010 and February 2014 were retrospectively reviewed. RESULTS: Operation was performed under local anesthesia in all cases. There was no technical failure. Concomitant inflow procedure (banding or aneurysmorrhaphy) was performed in 5 patients (38%). During follow-up (1 to 50 months, median 17 months), 3 patients died with functioning AVF and one was successfully transplanted. Two patients suffered from recurrent symptomatic stenosis of AVF and received percutaneous balloon angioplasty. Another 2 patients experienced AVF occlusion treated with interposition graft and manual fragmentation. Overall primary, assisted primary, and secondary patency rates were 77.5%, 92.3%, and 100% at 6 months and 66.1%, 92.3%, and 100% at 1 year, respectively. CONCLUSION: Although most patients presented with BC-AVF occlusion, technical success and access patency rates after CVT were favorable compared with historical data for interventional treatment. CVT should be considered as an appropriate option in selected patients with CAS.

The aim of this study was to identify the risk factor related to the need for operative treatment and avoid unnecessary non-operative management for intussusception in children. We retrospectively reviewed medical records of patient treated for intussusception at our institution between January 2006 and January 2013. Clinical features such as gender, age, seasonal variation, symptoms and signs, treatment results were analyzed. Univariate and multivariate analyses including a chi-square test for categorical variables and logistic regression analysis were performed. During the study period, 356 patients were treated for intussusception. 328 (92.1%) was treated successfully by the non-operative pneumoreduction, and 28 (7.9%) required operative management. On univariate analysis, risk factors which were related to the need for operative treatment were age, vomiting, bloody stool, lethargy, and symptoms duration. A logistic regression analysis in order to assess for independent predictors of operative treatment was performed. Age (<6 vs > or =12 months) (OR 4.713, 95% CI 1.198~18.539, p=0.027) and symptoms duration longer than 48 hours (OR 4.534, 95% CI 1.846~11.137, p=0.001) were significantly associated with a requirement for operative treatment. We conclude that younger age and a longer duration of symptoms (> or =48 hours) are the independent risk factor related to the need for operative treatment for intussusception. Early surgical intervention or transfer to a hospital with pediatric surgical capabilities should be considered for patients with these findings.

PURPOSE: We analyze the outcomes of open repair (OR) in patients with ruptured abdominal aortic aneurysm (RAAA) according to the anatomic suitability for endovascular aneurysm repair (EVAR). MATERIALS AND METHODS: We reviewed retrospectively all consecutive RAAA patients who underwent OR from January 2005 to March 2014. All suspected patients underwent preoperative computed tomography (CT). Outcomes were major morbidities and mortality. Multivariate analysis was performed by using logistic regression adjusted by controlled variables; gender, Hardman index, maximal aneurysmal diameter, rupture type, perioperative transfusion requirement, and perioperative urinary output. RESULTS: Among 54 consecutive patients with RAAA who underwent OR, 45 patients were included after exclusion of 9 patients (7, suprarenal; 1, infected; 1, inflammatory). Preoperative CT showed 27% (12/45) EVAR-suitable patients. Hostile neck anatomy was found in 88% (29/33) among unsuitable anatomy (UA) (n=33). The maximal aneurysmal diameter was statistically larger (83.1+/-21.0 mm vs. 68.8+/-12.3 mm, P=0.032) in the UA group. The 30-day mortality was 28.9% (13/45; 33% vs. 17% in UA group vs. suitable anatomy [SA] group, P=0.460; adjusted P=0.445). UA group had more patients with cardiac morbidity (55% vs. 25%, P=0.079; adjusted P=0.032; odds ratio, 12.914; 95% confidence interval, 1.238-134.675). There was no statistical difference in survival rate between SA and UA groups (74.1%, 74.1%, and 74.1% vs. 60.6%, 55.6%, and 32.4% at 1-, 3- and 5-year, respectively; P=0.145). CONCLUSION: In this study, relatively unfavorable outcomes were found in the EVAR-unsuitable group after OR in RAAA patients. However, unsuitable anatomy did not influence patient survival after OR by multivariate analysis.

PURPOSE: To determine the long-term outcomes of patients with diabetes mellitus (DM) and tissue loss who have undergone infrainguinal bypass surgery (IBS). METHODS: We retrospectively reviewed the medical records of 91 patients with DM and tissue loss who underwent IBS between July 2003 and December 2013. We determined the rates of overall survival (OS), amputation-free survival (AFS), limb salvage (LS), and graft patency (GP). In addition, we evaluated data to identify risk factors that affected long-term outcomes. RESULTS: The mean age of patients was 66 +/- 8 years, and 78 patients (85.7%) were men. The locations of tissue loss were toe on 76 limbs (71.6%), heel on 6 limbs (5.7%) and others on 24 limbs (22.6%). Single lesions were found in 81 limbs (76.4%). According to categorization by distal anastomosis artery, there were 57 popliteal (53.8%) and 49 infrapopliteal bypasses (46.2%). Among infrapopliteal bypasses, 5 cases (10.2%) were sequential bypasses. The OS at 1, 3, and 5 years was 90.5%, 70.9%, and 44.2%, respectively. At 1, 3, and 5 years, the LS was 92.1%, 88.9%, 88.9%, respectively; and AFS was 84.4%, 67.6%, 45.7%, respectively. At 1, 3, and 5 years, the GP was 84.8%, 74.5%, and 69.8%, respectively. Renal failure was a negative predictor for OS, and female gender was a negative predictor for GP. CONCLUSION: IBS for patients with DM and tissue loss led to acceptable OS, AFS, LS, and GP. Active revascularization for patients with DM and tissue loss can reduce the risk of major amputation.

PURPOSE: It remains controversial whether to use a tube graft or a bifurcated graft during open abdominal aortic aneurysm (AAA) repair, due to the potential for progression or development of a common iliac artery (CIA) aneurysm. This study evaluated the fate of CIA after tubular AAA repair. METHODS: On a retrospective basis, we reviewed 61 patients who underwent open AAA repair with a tube graft, between March 2000 and December 2009. Fifty-seven patients were included in this study; we excluded 4 cases in which the patients died in-hospital. Of those enrolled, 24 patients underwent follow-up computed tomography at least 1-year after surgery. CIAs were categorized into 3 groups: normal (< or =12 mm), ectasia (range, 13 to 18 mm), and aneurysm (range, 19 to 25 mm). The incidence of CIA aneurysm rupture was investigated, and the expansion rate of CIA was calculated. RESULTS: Mean patient age was 64 years and 73% of patients were male. Preoperatively, 8 patients had 2 normal CIAs, 14 patients had one CIA aneurysm at least, 27 patients had one CIA ectasia, and 8 patients were unknown. There was a mean follow-up of 51 months; no deaths were caused by rupture of CIA aneurysm, and no patient underwent invasive treatment for a CIA aneurysm. The mean follow-up for 24 patients with 48 CIAs was 45 months. The mean expansion rate of CIA was 0.5 mm/y. CONCLUSION: AAA repair using a tube graft was a safe and durable procedure. However, a bifurcated graft should be considered when patients are young and there is the expectation of a long life expectancy is anticipated allowing for a CIA expansion rate of 0.5 mm/y.

Celiac artery aneurysms are extremely rare vascular lesions usually diagnosed by chance. A 62-year-old male was being referred to Kyungpook National University Hospital with a seven day history of upper right quadrant abdominal pain. A computed tomography scan revealed an acute cholecystitis and a 7-cm sized huge aneurysm located from the origin of celiac artery to the bifurcation of celiac artery. After an initial cholecystectomy, the aneurysm was opened and the origin of celiac artery was oversewn with aorta followed by transposing and implanting the conjoined splenic-hepatic trunk to supraceliac aorta. The patient was discharged without complications on the tenth postoperative day. Conjoined splenic-hepatic trunk transposition for the repair of a celiac artery aneurysm may be an appropriate alternative option especially in cases complicated with other infectious conditions.

PURPOSE: To report follow-up data on upper extremity (UE) macroreplantation in patients with traumatic amputation injuries. METHODS: Between 1996 and 2003, 11 patients underwent UE macroreplantation at a single institution. All patients had an open fracture (n=9; upper arm, 5; forearm, 4) or an open dislocation of the elbow (n=2), combined with neurovascular and soft tissue transection injuries. The replantation procedures were performed on an emergency basis by a multi-departmental team. The mean warm ischemic time was 328 minutes (range, 165 to 480 minutes). Functional recovery of the replanted UE was evaluated with Chen's classification system, and patient satisfaction was determined using Russell's questionnaire; periodic examinations were conducted over a minimum follow-up period of 2 years. RESULTS: Early complications consisted of 2 arterial thromboses, 1 soft tissue infection resulting in sepsis, and 1 episode of acute renal failure; UE reamputation was required in 2 patients. As a result, limb salvage was achieved in 82% of patients (9/11). A functional extremity, defined as grades I and II using Chen's criteria, was preserved in 33.3% of patients with successfully replanted limbs. Despite the objectively poor rate of function preservation, 89% of patients who had successful replantation procedures were satisfied with the results. CONCLUSION: Even though the functional recovery rate was low, UE macroreplantation resulted in acceptable limb salvage rates and good patient satisfaction.

PURPOSE: In contrast to proximal deep vein thrombosis (DVT), the treatment of isolated calf vein thrombosis (ICVT) remains controversial. This study aimed to investigate early treatment outcomes of ICVT after total knee arthroplasty (TKA). METHODS: Medical records of 313 patients who underwent TKA from October 2007 to December 2009 were retrospectively reviewed. A DVT-computed tomography (CT) was performed 7 days after surgery. ICVT was identified in 76 limbs of 73 patients. Of them, follow-up DVT-CT was available in 39 limbs of 37 patients. The patients with ICVTs were categorized into two groups: oral anticoagulation group (group I, 17 patients with 18 limbs) and conservative treatment group (group II, 20 patients with 21 limbs). Group I received an oral vitamin K antagonist for 3 to 6 months following low molecular weight heparin. Change of thrombus extent and development of pulmonary embolism (PE) was assessed in follow-up DVT-CT. RESULTS: Mean age was 68 years and 95% were female. Of 39 limbs with ICVT, 16 (41%) involved major lower leg veins (posterior tibial vein or peroneal vein), 13 (33%) involved muscular veins (soleal vein or gastrocnemius vein) and 10 (26%) involved both. During 1 to 6 months, follow-up DVT-CT revealed complete thrombus resolution in all limbs and there was no proximal propagation of thrombus or PE in both groups. CONCLUSION: There is no evidence of DVT propagation or newly developed PE in the conservative treatment group. This result suggests that anticoagulation therapy for ICVT patients without PE after TKA may not be mandatory.

PURPOSE: To evaluate shunt rate and discuss the resultsrelated to selective shunt placement during carotid endarterectomy (CEA) using routine awake test. METHODS: Patients with CEA from 2007 to 2011 were retrospectively reviewed from prospectively collected data. The need for shunt placement was determined by the awake test, based on the alteration in the neurologic examination. We collected data by using the clinical records and imaging studies, and investigated factors related to selective shunt such as collateral circulation and contralateral internal carotid artery (ICA) stenosis. RESULTS: There were 45 CEAs under regional anesthesia with the awake test in 44 patients. The mean age was 61.8 +/- 7.1 years old. There were 82.2% (37/45) of males, and 68.9% (31/45) of symptomatic patients. Selective shunt placement had been performed in only two (4.4%) patients. Among them fewer cases (4%) had severe (stenosis >70%) contralateral ICA lesions, and more cases (91%) of complete morphology of the anterior or posterior circulation in the circle of Willis. There was no perioperative stroke, myocardial infarctionor death, and asymptomatic new brain lesions were detected in 4 patients (9%), including 2 cases of selective shunt placement. CONCLUSION: CEA under routine awake test could besafe and feasible method with low shunt placement rate in selected patients.
