ABSTRACT
We report a rare case of surgical treatment of arteriomegaly with multiple aneurysms. The patient was a 76-year-old man who was suffering from swelling, pain, and numbness of his left lower extremity. Three-dimensional computed tomography (3D-CT) revealed arteriomegaly from the left external iliac artery to the popliteal artery with ruptured superior gluteal arterial aneurysm and superficial femoral aneurysm, and with unruptured external iliac aneurysm and popliteal aneurysm. We performed left external iliac artery—posterior tibial artery bypass, exclusion of superior gluteal aneurysm, and resection of three other aneurysms. Because of arteriomegaly, back flow from the dilated arterial branches was considerable, and the femoral artery was expanded with tension despite of distal and proxymal clamp. We therefore divided the femoral artery to avoid development of a aneurysm. The postoperative course was uneventful and 3D-CT showed good bypass flow and thrombotic occlusion of the residual femoral artery.
ABSTRACT
A 72-year-old man underwent hemiarch replacement of the distal aortic arch with hypothermia and selective cerebral perfusion because of a large pseudoaneurysm of the aortic arch. Histological examination revealed a penetrating atherosclerotic ulcer had caused aortic perforation and resultant pseudoaneurysm formation.
ABSTRACT
Y-graft replacement was successfully performed in a patient aged 93 years with ruptured infrarenal abdominal aortic aneurysm. The patient was in shock on arrival and underwent an emergency operation with the administration of cathecholamines. The ruptured infrarenal abdominal aortic aneurysm with a large hematoma, which was located in the area of the left common iliac artery, was 10cm in the maximum diameter. The bilateral common iliac arteries were strongly calcified and occluded. The distal end of the graft was anastomosed to the external iliac artery. The patient's postoperative course was uneventful.
ABSTRACT
A non-anastomotic false aneurysm occurred in a 77-year-old male 11 years after bypass grafting between the left external iliac artery and the right femoral artery using a Cooley double velour knitted Dacron graft. The false aneurysm was caused by rupture of an artificial graft. A partial resection of the graft and its replacement using a Hemashield<sup>®</sup> graft were successfully performed. It was speculated that the mechanical stress by the inguinal band degenerated graft fibers and developed aneurysmal formation.
ABSTRACT
A follow-up study of 98 patients undergoing abdominal aortic aneurysm (AAA) repair for 44 months, ranging 2 to 113 months, revealed no difference in 5-year actuarial survival between patients aged 75 or older and patients aged less than 75. The 5-year actuarial survival of ruptured and nonruptured AAA cases was 469% and 71.2%, respectively (<i>p</i><0.01). Late deaths after the repair of ruptured AAA were all due to atherosclerotic diseases. During a follow-up period after AAA repair, 9 patients were diagnosed as having malignant diseases with a fatal outcome in 6. Careful attention to atherosclerotic and malignant diseases is indispensable for follow-up management after AAA repair.
ABSTRACT
A 52-year-old male was diagnosed as having aortic stenosis secondary to a bicuspid aortic valve associated with Klippel-Feil syndrome. Aortic valve replacement was successfully performed without any problems in the surgical or anesthesiological management. Only five such cases including ours, who underwent cardiac surgery have been reported. It is possible to perform cardiac surgery for patients with Klippel-Feil syndrome of their cardiac function can be well preserved.
