Surgical treatment of aneurysms of the transverse aortic arch.

Over the past four years, 21 patients have been operated for aneurysms of the thoracic aorta requiring aortic arch reconstruction. The causes of the aneurysms were dissecting aneurysms of the aorta (type A) in 16 patients and atherosclerosis in 5 patients. To prevent cerebral ischemia during operation, selective cerebral perfusion (SCP) (600 ml/min at 25 degrees C) was employed in 11 patients and hypothermic circulatory arrest (HCA) at 15 degrees C in 10 patients. There were three early deaths (14.3%) in the series. There were no serious neurologic complications in either group. The present data suggests that both selective cerebral perfusion SCP and HCA are useful methods for cerebral protection during resection of aortic arch aneurysms, although the latter method has the limitation of restricted cerebral arrest time.

Aneurysm of the celiac artery.

A 50-year-old male with asymptomatic aneurysm of the celiac artery is described and the diagnosis and surgical treatment as well as problems and considerations involved in surgical management are discussed in conjunction with a review of the literature.

Saphenous vein aneurysm following coronary artery bypass grafting.

Aneurysmal dilatation in a venous graft following coronary artery bypass grafting (CABG) is extremely rare. Recently, we performed a resection of aneurysm and redo CABG in two patients who developed aneurysmal changes in the graft, one after 1 year and 10 months and the other after 3 years and 11 months, and obtained good results.

Graft inclusion technique for thoracoabdominal aortic aneurysms involving visceral branches with the aid of a femoro-femoral bypass.

Eleven patients in our institution with thoracoabdominal aortic aneurysms involving the celiac, superior mesenteric and renal arteries underwent surgical treatment with the aid of a partial femoro-femoral bypass during the last three years. Three patients with expanding aneurysms underwent emergency operations. Another three patients with extensive aneurysms had two-stage operations: initial aortic arch or descending thoracic graft replacement followed by thoracoabdominal graft replacement in the second stage. Exposure of the aneurysms was made through a left transthoracic, retroperitoneal abdominal approach in all patients. The surgical technique employed in most cases in this series was graft inclusion with direct reattachment of the visceral vessels by anastomosis to an opening made in the graft. Pairs of intercostal and lumbar arteries between the levels of the ninth thoracic and fourth lumbar regions were reconstructed in a similar fashion on the basis of monitoring somatosensory evoked potentials. The operations were performed with the aid of a partial femoro-femoral bypass with selective celiac and renal arterial perfusion in most cases. All patients but one survived the operation and are leading normal lives late in the postoperative period. Graft inclusion with the aid of a partial bypass is a valid technique for the treatment of thoracoabdominal aortic aneurysms involving visceral branches.
