Abstract

Fourteen surgical cases of acute dissecting aneurysms of Stanford type A were reported. Clinical symptoms, operative methods, pathophysiology, cerebral protection, supported systems, and prognosis were examined. All patients underwent surgery within 5 days of symptom onset. The patient population consisted 8 males and 6 females with a mean age of 56.6 years. Ascending aortic replacement was performed using a vascular graft 12 patients. ECC was performed under deep hypothermia. Femoral artery cannulation and retrograde cerebral perfusions was performed in all cases. The ascending aorta was the site of entry in 13 of the 14 cases. Whenever feasible, enhanced CT and aortography were performed to confirm the entry lesion. Two patients expired. One patient died intraoperatively due to massive bleeding. The other patient, while hospitalized, experienced a cerebrovascular accident and died due to pneumonia. All other patients ran an uneventful post-operative course without cerebrovascular accident. In conclusion we think that although ascending aorta replacement using prosthetic grafts is not ideal for patients with Stanford type A dissecting aneurysms, it is a viable option for emergency cases. We found retrograde circulatory cerebro...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
