A 49-year-old man with drowsy mentality was diagnosed with acute type A aortic dissection; he underwent an emergency operation. When selective antegrade cerebral perfusion was initiated, the right regional cerebral oxygen saturation ($rSO_2$) decreased as compared to the left one. Adequate blood flow was perfused through the branch of the artificial graft, after distal anastomosis, but the right $rSO_2$ did not recover. Angiography revealed another intimal tear on the right common carotid artery. A stent was then inserted. The right $rSO_2$ promptly increased to the same level as that of the left one. The patient was discharged without any neurologic complications.

Herein, we present a case of a successful treatment of persistent type 2 endoleaks associated with aneurysmal sac enlargement after endovascular aneurysm repair in an elderly patient. We confirmed the diagnosis by abdominal computed tomography and selective angiography revealing an 11.0-cm aneurysm sac with type 2 endoleaks. An attempt for the endovascular embolization of collateral arteries was unsuccessful due to anatomic variations and their multiple complex communications. Instead, transperitoneal sacotomy and direct suturing on the feeding target vessels was successfully performed without any endograft damage. In conclusion, sacotomy appears to be a feasible therapeutic substitute where endovascular or other techniques have a high risk of failure and lead to unsuccessful results.

Ureterosciatic hernia is extremely rare. In ureteral herniation, ureter prolapses occur through either the greater or lesser sciatic foramen. Atrophy of the piriformis muscle, hip joint diseases, and defects in the parietal pelvic fascia are predisposing factors for the development of ureterosciatic hernia. Most symptomatic patients have been treated surgically, with conservative treatment reserved only for asymptomatic patients. To the best of our knowledge, long-term follow-up outcomes after ureterosciatic hernia management are sparse. In this paper, we report the case of a 68-year-old woman who presented with colicky left abdominal pain. After computed tomography (CT) scan and anterograde pyelography, she was diagnosed ureterosciatic hernia with obstructive uropathy. We performed ureteral balloon dilatation and double-J ureteral stent placement. After this minimally invasive procedure, CT scan demonstrated that the left ureter had returned to its normal anatomical position without looping into the sciatic foramen. The patient remained asymptomatic with no adverse events 7 years after the minimally invasive procedures. This brief report describes ureterosciatic hernia successfully managed with minimally invasive procedures with long-term follow-up outcomes.

Clusterin is an 80 kDa heterodimetric glycosylated protein and it plays diverse biological roles in various tissues and organs. Clusterin is reported to be associated with the pathogenesis of coronary artery disease and atherosclerosis. Therefore, we investigated the genotype for the A/G polymorphism at the position 4,183 of clusterin gene in Koreans and compared genotype of patients with control group. 100 patients (Male 63, Female 37), who previously underwent coronary artery stent due to ischemic heart disease and 100 controls (Male 36, Female 64) participated in this study. There was a significant association between 4,183 A/G polymorphism in clusterin gene and coronary artery disease (CAD). The present study shows that clusterin gene A/G polymorphism may be associated with the pathogenesis of CAD. Further studies with larger population may be needed for the development of diagnostic methods at genetic level such as DNA chip.

Subclavian injuries in blunt trauma are reported in less than 1% of all arterial injuries or chest related injuries. We report a female 68 yr-old patient whom has visited our emergency center due to a motorcycle traffic accident with complaints of right chest wall and shoulder pain. Her injury severity score was 22 and she was found with a comminuted clavicle fracture and subclavian artery injury. She developed delayed symptoms of pallor, pain and motor weakness with loss of pulse in her right arm. Attempts at intervention failed and thus, she underwent emergency artificial graft bypass from her subclavian artery to her brachial artery. Her postoperative course was uneventful and she is happy with the results. Although rare, a high index of suspicion for the injury must be noted and the inevitable surgical option must always be considered.

We report the case of a patient with a chronic DeBakey type IIIb aneurysm who underwent thoracic endovascular aortic repair to seal the primary entry tear and stent-graft insertion to cover the re-entry tear at the renal artery. The procedure was performed in order to achieve complete thrombosis in the entire thoracoabdominal false lumen, leading to favorable aortic remodeling. Simultaneously, ethanol ablation and renal artery embolization were performed to treat a renal tumor suspicious of renal cell carcinoma. Radical nephrectomy then confirmed clear cell carcinoma. To the best of our knowledge, no other cases of this type have been reported in the Korean literature.

A 49-year-old female patient who had obstruction of superior vents cave(SVC) with SVC syndrome was successfully managed by bypass operation of superior vents cava with spiral vein graft. A composite spiral vein graft was placed between the right innominate vein and the right atrium to bypass the occluded SVC. The graft was constructed from the patient's own saphenous vein, which was split longitudinally and wrapped around a stent in spiral fashion and the edges of the vein were sutured together to form a large autogenous conduit. The patient was relieved o SVC obstructive symtoms and signs and discharged 21 days postoperatively without any complication.

Aorto-iliac artery aneurysms are very rare and the natural course of this disease is not well known. However, the risk of rupture is high and the mortality rate after rupture is extremely high. Preserving the pelvic circulation is important for the treatment of aorto-iliac artery aneurysms. We report here on a case of a patient suffering with aorto-iliac artery aneurysms, and these were treated by a hybrid endovascular operation that combined an open bypass of both iliac vessels with endovascular repair.

A 67-year-old female patient was treated with conventional total arch replacement and insertion of a stented elephant trunk (SET) graft into the descending thoracic aorta for acute DeBakey type I aortic dissection at one time. She had been treated with right coronary artery stent insertion for acute myocardial infarct 4 days earlier, and at that time, she was diagnosed with acute DeBakey type I aortic dissection from the ascending aorta to the suprarenal artery based on trans-esophageal echocardiography and aorta computed tomography. Through a median sternotomy, we inserted the SET graft through the opened aorta to the descending aorta. We also performed anastomosis between the proximal stented graft and the distal aortic arch, and then performed total arch replacement. For acute DeBakey type I aortic dissection, we report total arch replacement with insertion of a SET graft as a combination of conventional surgery and the interventional technique.

A 34-year-old man who had undergone aortic valve replacement 8 years ago underwent an additional Bentall operation due to mechanical valve dehiscence 2 years later. Subsequently, he was diagnosed with Behçet disease and Batter syndrome. A week after being hospitalized again due to chest pain and dyspnea, a large pseudo-aneurysm was detected on computed tomography. Because of the excessively large size of the pseudo-aneurysm, surgical treatment seemed very risky. Therefore, we planned to perform thoracic endovascular aortic repair (TEVAR) and treated him successfully. However, the patient experienced recurrence of the same symptoms 4 months later, and was found to have type IV endoleak. He received a TEVAR procedure again, and it was successful.
