Ten patients with rupture of the aortic isthmus due to blunt trauma were subjected to early surgical intervention with nine survivors (mortality 10%). A high degree of suspicion is necessary in order to make an early diagnosis. Left atrium (LA) to femoral artery (FA) bypass using systemic heparinization was used in all cases and bypass instituted before the aorta was prepared for clamping. Advantages of LA to FA bypass are as follows: (a) Technically easy; (b) Better control of patient during preparation of the aorta for clamping; (c) Provides the surgeon with more time to perform a safe operation.
Aneurysms of the left atrium or its appendage are uncommon. Some occur with an intact pericardium and others are associated with a pericardial defect. The majority of patients are asymptomatic, but dysrhythmias and systemic embolism may occur. The condition should be suspected after chest radiography but can only be confirmed by angiocardiography. Resection is advised with cardiopulmonary bypass standing by. A patient with an intrapericardial aneurysm of the appendage correctly diagnosed by angiocardiography and successfully treated by simple excision is described.
