Systemic multiple aneurysms are rare, and an association between intracranial and visceral arterial or abdominal aortic aneurysm in the same patient is a very rare occurrence. We report herein three such cases. In one case, aneurysms of the right internal carotid artery(ICA) and the right middle cerebral arterial bifurcation(MCAB) coexisted with the inferior pancreaticoduodenal arterial pseudoaneurysm and two ileal arterial aneurysms. In another case, the patient had the A-com arterial aneurysm and the right renal arterial aneurysm. And in the other patient, he had the right vertebral artery dissecting aneurysm with the abdominal aortic aneurym. Initially, all patients were referred to our hospital with subarachnoid hemorrhage(SAH), and thereafter first two patients developed visceral arterial aneurysm rupture in the course of hospital stay and in the last patient, the abdominal aortic aneurysm was detected incidentally during carotid angiogram for Guglielmi detachable coil(GDC) embolization of vertebral dissecting aneurym. After thorough review of our cases together with pertinent literatures, we emphasize the possibility of underlying extracranial aneurysms in ruptured intracranial arterial aneurysm patient and it's uncommon but fatal complication.

A successful resection of dissecting thoracoabdominal aortic aneurysm is presented in a patient who had undergone kidney transplantation 20 months previously. Because the transplanted kidney is more sensitive to ischemia than the normal kidney, a femoro-femoral bypass with a pump oxygenator was used for perfusion of the transplanted kidney during crossclamping. During the clamping time of 1)8 minutes, kidney perfusion was maintai ed with a perfusion pressure of (19 to 31) 27mmHg and the flow was 0.53 to 0.81 L/min. 32mm sized Hemashield (22 Cm in length) was interposed. The postoperative course was uncomplicated. We believe that performing the femoro- femoral bypass with a pump oxygenator is an effective and simple method for renal and spinal protection in such operations.

We experienced 20 patients with Takayasu`s disease who required 22 surgical procedures for critical arterial stenoses, aneurym of descending thoracic aorta, and aortic regurgitation from 1986 to 1993.Five patients had type I arteritis, seven patients had type II , seven patients had type III, and one patients had type IV.15 patients were female and 5 patients were male.Patients` ages ranged from 17 to 47 years and mean age was 29.1 years. The surgical procedures were as follows;autotransplantations of kidney[3], aortic valve replacements[2], ascending aorta-bilateral internal carotid artery bypasses[2], unilateral renal artery bypasses[2], bilateral renal artery bypasses[3], replacement of descending thoracic aorta[1], ascending aorta-abdominal aorta bypass[1], ascending aorta-right internal carotid artery bypass[1], ascending aorta-right internal carotid artery and left subclavian artery bypass[1], left common carotid artery-left-subclavian artery bypass[1], pulmonary artery angioplasty[1], left femoro-bilateral axillary bypass[1] and others[2]. There was no hospital death.Mean duration of follow-up was 42.7 months[ranged from 3 to 96 months].There was one late death and late mortality rate is 5.9%.Two patients was underwent second vascular procedures, one after 5 years and the other after 5 months.The other patients have done well after surgery.

Background: Sinus valsalva aneurysm (SVA) is a rare disease, and it is frequently accompanied by ventricular septal defect and aortic valve regurgitaion. For treatment of SVA, several surgical mordalities were applied, but there was no report on the long-term result after surgical repair in Korea. We reviewed our 28 years of experiences and analyzed the long-term results after treatment of sinus valsalva aneurysm with or without rupture. Material and Method: Between March 1974 and February 2002, 81 patients were operated under the impression of sinus valvsalva aneurysm or sinus valsalva aneurym rupture. Retrospectively we reviewed the patients' record. Mean age of patients was $29.2\pm11.5$ and there were 49 males. Accompanyng diseases were as follows: VSD in 50, PDA in 2, Behcet's disease in 2, TOF in 1, RVOTO in 1, AAE in 1. Seventy-seven $(95\%)$ patients had sinus valsalva rupture and in 14 patients, subacute bacterial endocarditis was accompanied. Degree of aortic valve regurgitation was as follows: grade I: 8, II: 10, III: 9, IV: 4. Most common rupture site was right coronary sinus (66 patients, $81\%$) and most common communication site was right ventricle (53 patients). In repair of sinus valsalva rupture, patch was used in 37 patients, and direct suture was done in 38 patients. Result: There was one surgical death $(1.2\%)$. Follow up was done in 78 patients $(97.5\%)$, mean follow up period was $123.3\pm80.9(3\~330\;months)$. During the follow up period, 3 patients died $(3.8\%)$. One patient died of heart failure, another patient died of arrhythmia and the other one died of unknown cause. In two patients, complete atrio-ventricular block was developed during follow up period, and there was no operation related event or complication. Kaplan-Meier survival analysis revealed $92.5\pm3.5\%$ survival at 15 and 27 years and it seems to be satisfactory. Conclusion: Long-term surgical results and survival is satisfactory after repair of sinus valsalva aneurysm with or without rupture.
