Conventional surgery for aortic arch aneurysms have many postoperative complications and a high mortality rate due to prolonged cardiopulmonary bypass time, especially in high risk patients. In this report, we present two cases of a hybrid procedure that involves open brachiocephalic bypass with concomitant endovascular arch stent grafting in high risk patients with distal aortic arch aneurysm.

A 50-year-old male patient was admitted due to right ventricular & aortic foreign bodies with ascending aortic pseudoaneurysm. The patient had a history of Kirschner wire fixation of right sternoclavicular joint 3 months ago. Under cardiopulmonary bypass, two K-wires were removed and injured pulmonary valve leaflet and aortic wall were repaired successfully The postoperative course was uneventful and the patient was discharged on the 14th postoperative day.

We experienced a case of thoracic aortic aneurysm combined with coronary artery disease. A 68-year-old man complained of anginal pain in the left anterior chest and nonspecific pain in the posterior chest. The aneurysm was extending from left subclavian artery to the diaphragm and sign of impending rupture was noted in the chest CT. Coronary angiograms r vealed significant obstruction of left circumflex coronary artery(>95%) and left anterior descending artery(>50%). Exposure was obtained through the left posterolateral thoracotomy incision in the 4th intercostal space and then partial femoro-femoral cardiopulmonary bypass was established. After aortic cross clamping, the aneurysmal sac was opened and repaired with interposition of 26 mm Hemashield graft. Under the beating heart with femoro-femoral cardiopulmonary bypass, aorto-left circumflex coronary bypass with autogenous saphenous vein used as conduit was performed. Postoperatively multiple cerebral infarction ensued due to intraoperative hypovolemic shock and hypoxic brain damage during cardiopulmonary bypass. Currently, the patient's mental status is drowsy and in an improving state.

Between 1987 and 1994, 21 patients were treated surgically for aortic aneurysm involving the thoracoabdominal aorta. There were 11 males and 10 females, and their age ranged from 20 to 67 years old and mean age was 41.5 years. Many complained of back pain, chest pain or discomfort, and flank pain, but three patients were asymptomatic. 15 patients had chronic dissection (71.4%) and 6 had nondissecting fusiform or saccular aneurysm(28.5%), and of those 15 patients with chronic dissection, 6(28.5%) had atherosclerosis assniated with hypertension, 5 (23.8%) were Martian syndrome, and 2 (9.5%) were associated with pregnancy. The diameter of an aneurysm ranged from 6cm to 12cm, and their extent was classified as type I in 7(33.3%), type II in 8(38.1%), type III in 3(14.3%), and type IV in 3(14.3%) patients based on Crawford classification for TAA . Diseased aorta was replaced with artificial vascular graft in all but one patient. In whom the aortic tear site due to pseudoaneurysm was closed by primary suture. For the spinal cord protection during the operation, we used partial cardiopulmonary bypass (FV-FA or PA-FA bypass) in 12 patients (57.1%), Biopump (LA-FA bypass) in 4(19.0%), total circulartory arrest and CPB in 2 (9.5%), Gott's heparinized shunt in 1(4.7%), and simple aortic cross clamping in 2 (9.5%). The most common complication after the operation was hoarseness due to unilateral vocal cord palsy which onured in 5 patients (23.8%), and the next common complication was wound infection in 4 patients(19.0%), paraplegia in 2 patients (9.5%), chylothorax in 1 patient(4.7%). The hospital mortality rate was 9.5% (2deaths), and there was no late death. Our experience shows that the graft replacement of TAAA had reasonable rate of mortality, low rate of serious complication, and provided good post operative state of the pati nts, and since the thoracoabdominal aortic operation is not a high risky procedure anymore, we recommend a radical operation for the indicated patients.

Aortic arch aneurysm generally requires an urgent treatment due to the risk of catastrophic aortic rupture. However conventional surgery for aortic arch repair still carries significant risks of postoperative morbidity and mortality, especially in patients with old age. In an effort to correct the aortic pathology while minimizing the risks of complication, we performed a hybrid technique which comprises the off pump arch aortic stent grafting in an 86-old male patient with an aortic arch aneurysm.

Background: Surgery of abdominal aortic aneurysm revealed high operative mortality. We reviewed our 11-years' experiences of abdominal aortic aneurysm operation and wish to obtain information on the treatment. Material and Method: From Jan. 1990 to Dec. 2000, 48 patients were operated due to abdominal aortic aneurysm in Yonsei Cardiovascular Center Mean age was $62.8{\pm}12.7$ and there were 40 males and 8 females. Among 48 patients, nine patients had ruptured abdominal aortic aneurysm, and mean aneurysm diameter of non-ruptured cases was $8.8{\pm}2.4$cm. Result: There were 6 early deaths, and early mortality was 12.5%. Among 9 patients of preoperative aneurysm rupture, three patients died (33.3%), and among 39 patients of non-ruptured cases, 3 patients died (7.7%). Among preoperative variables, age (p<0.05), preoperative BUN level (p<0.05), and DM (p<0.05) were risk factors of early mortality. Among discharged 42 patients, 40 patients were followed up (f/u rate=95.2%) and mean follow up was $3.6{\pm}0.2$ years. During follow up periods, five patients died (late mortality=11.9%), and Kaplan-Meier survival analysis revealed $81.7{\pm}7.6$% survival rate at five and ten year. Linealized incidence of graft related event was 3.53% per patient-year. Conclusion: Surgical mortality of ruptured abdominal aortic aneurysm was higher than non-ruptured cases; therefore, early resection of the aneurysm can decrease the surgical mortality.

Chronic pulmonary obstructive disease is known to be a significant risk factor for mortality in patients who under-went operation for abdominal aortic aneurysm. To decrease perioperative respiratory complication in these patients, maintenance of self respiration as possible is one of the better method. A seventy-seven year old male patient complained of abdominal pain and he was diagnosed for 9 cm sized abdominal aortic aneurysm. But he had severe chronic obstructive pulmonary disease which was expected to increase surgical mortality. So we introduced epidural anesthesia with maintenance of self respiration and performed surgical resection and graft replacement of abdominal aorta, and he recovered without any complication.

Syphilitic aortic aneurysm is a rare lesion today. We experienced a case of huge syphilitic ascending aortic aneurysm with aortic insufficiency. Surgical correction was done by replacement of ascending aorta with woven Dacron graft and aortic valve replacement under cardiopulmonary bypass. There is no abnormality in postoperative aortography. The postoperative course was uneventful.

A 70-year old male with dilated cardiomyopathy was admitted to our hospital because of a renal stone, and a supra-renal abdominal aortic aneurysm was detected during work-up. We performed a hybrid surgery using an endovascular stent because of his co-morbidities. The operation consisted of removal of the renal stone, de-branching of the visceral artery and both renal arteries from the abdominal aorta, reperfusion of the de-branched arteries with retrograde bypass surgery using two Y-graft from the left external iliac artery, and deployment of stent graft in the abdominal aorta. Therefore, we report a case of hybrid surgery for supra-renal abdominal aortic aneurysm.

Endovascular treatment of the aortic aneurysm with a stent graft is rapidly evolving. We describe here a case of hybrid TEVAR (thoracic endovascular aortic repair) in which the stent grafts were placed in the aortic arch after debranching of the arch vessels. The patient had undergone ascending aorta replacement for acute type I aortic dissection 2.5 years earlier. The aneurysmal change of the distal dissection progressed with time. A provisional bypass surgery from the ascending aorta to the innominate artery and left carotid artery was performed and then stent grafts were inserted via an antegrade route that covered the whole aortic arch and proximal descending thoracic aorta.
