Emergent or elective operation for symptomatic abdominal aortic aneurysm.
The patient with the symptomatic abdominal aortic aneurysm (AAA) presents a management dilemma, ie, emergent, urgent, or elective operation. The mortality for 38 patients with a ruptured AAA prior to 1972 was 61%. That year, a policy of immediate operation was instituted for patients with symptoms that might be referable to a ruptured AAA. It is concluded that an immediate operation on the patient with a symptomatic but intact AAA resulted in an excessively high mortality. Thus, the indications for an immediate operation on these patients should be based on clinical judgment; attempting to differentiate between the patient with the ruptured and the patient with the intact aneurysm. Hemodynamic data (blood pressure hematocrit reading) suggesting a decrease in blood volume dictate an immediate operation. An urgent operation on the well-prepared patient should be performed on all patients with a symptomatic aneurysm in which the clinical and hemodynamic findings do not suggest that it has ruptured.
