Backgrouds: It is almost universally accepted that occlusive vascular diseases are best managed by anatomical reconstruction. However, the mortality and the morbidity have limited this operation for patients with high operation risks. In these patients, palliative operations such as extra-anatomic bypass and lumbar sympathectomy, are accepted as useful treatment. Material and Method: A retrospective study was conducted in 38 patients who underwent palliative operations for occlusive vascular disease at Korea University Guro Hospital between 1996 and 2000. Mean age of the patients was 60.37 $\pm$ 17.65 years, and preoperative diagnoses were atherosclerosis in 32 patients, Buerger's disease in 4 patients, Raynaud's syndrome in 1 patient and SVC syndrome in 1 patient. Result: Extra-anatomic bypass(40procedures), lumbar sympathectomy(17), thromboembolectomy(7) and femoral artery graft interposition(1) were performed. Six patients were required reoperation due to graft flow failure or fistula. Three year primary patency rate of entire operations was 78.29 $\pm$ 8.81%, and the correlation between type of operation and patency rate was not statistically significant. Conclusion: Palliative operations for occlusive vascular disease are useful treatment in limited patients with high operation risks or limited life expectancy.

In treating uncomplicated abdominal aortic aenurysm, endovascular aortic aneurysm repair (EVAR) has been employed as a good alternative to open repair with low perioperative morbidity and mortality. However, the aneurysm can enlarge or rupture even after EVAR as a result of device failure, endoleak, or graft migration. We experienced two cases of aneurismal rupture after EVAR, which were successfully treated by surgical extra-anatomic bypass.

Under median sternotomy and left thoracotomy, extra-anatomic aorta bypass between ascending aorta and descending thoracic aorta without cardiopulmonary bypass support has been done effectively and easily without complications for a selected case of atypical coarctation associated with hypoplasia of aortic arch. It should be considered as an alternative operative technique for complex aortic arch reconstruction.

Tuberculous aneurysm of the aorta is exceedingly rare. To date, the standard therapy for mycotic aneurysm of the abdominal aorta has been surgery involving in-situ graft placement or extra-anatomic bypass surgery followed by effective anti-tuberculous medication. Only recently has the use of a stent graft in the treatment of tuberculous aortic aneurysm been described in the literature. We report two cases in which a tuberculous aneurysm of the abdominal aorta was successfully repaired using endovascular stent grafts. One case involved is a 42-year-old woman with a large suprarenal abdominal aortic aneurysm and a right psoas abscess, and the other, a 41-year-old man in whom an abdominal aortic aneurysm ruptured during surgical drainage of a psoas abscess.

Extra-anatomic graft bypass is frequently performed instead of standard infrarenal aorto-iliac reconstruction in patients with Leriche syndrome in whom the thrombus extends to the level of the renal arteries. However, many different surgical options are still being attempted due to the unsatisfying long-term graft patency. We performed a descending thoracic aorto-bifemoral bypass graft with 14 and 14-7-7 mm artificial vessels through a posterolateral thoracotomy, a median laparotomy, and a longitudinal inguinal incision in a 48-year-old male who suffered from claudication with Leriche syndrome. After surgery, the patient recovered well and was discharged. The patient walked well without any symptoms during the 6 month follow-up period in the outpatient department. We have concluded that descending thoracic aorto-bifemoral bypass grafting could be considered as an alternative method for patients with Leriche syndrome in whom standard infrarenal aorto-iliac reconstruction is unsuitable.

Background: A hybrid procedure using an open surgical extra-anatomic bypass of aortic arch vessels and thoracic endovascular aortic repair (TEVAR) is less invasive than open surgery, and provides a suitable proximal landing zone. Here we report our experience with a hybrid TEVAR procedure at a single center. Material and Method: We retrospectively reviewed consecutive patients with thoracic aortic disease who received a hybrid TEVAR procedure between August 2008 and January 2010. Patients' data were prospectively collected and mean follow-up was $10.8{\pm}5.5$ months (range 3~20). Result: Nine patients (7 males and 2 females) with a mean age of $63.8{\pm}15.8$ years (range 38~84) underwent a hybrid procedure. Five patients had an arch or a proximal descending aortic aneurysm, two had a dissecting aneurysm of the descending aorta, and two had an aneurysm of the ascending arch and descending aorta. Mean expected mortality calculated by logistic EuroSCORE was 21%. Six patients underwent debranching and rerouting from ascending aorta to arch vessels, 2 had carotid-carotid bypass grafting, and 1 underwent carotid-axillary bypass grafting. Mean operation time was $221.4{\pm}84.0$ min (range 94~364). Deployment success of endovascular stent grafting was 100% with no endoleak on completion angiography. There was no mortality, and a small embolism in the branch of the right opthalmic artery in one patient. During follow-up, one intervention was required for the endoleak. Actuarial survival at 20 months was 100%. Conclusion: Early and mid-term results are encouraging and suggest that hybrid TEVAR procedures are less invasive and safer and represent an effective technique for treating thoracic aortic disease.
