ABDOMINAL AORTIC ANEURYSM WITH COINCIDENTAL MALIGNANCY

In 16 cases of abdominal aortic aneurysm (AAA) which we have treated surgically during the past two and half years, coincidental malignancy was encountered in four, i.e., three of gasric cancer and one of pulmonary cancer. The diagnosis of AAA and gastric or lung cancer was made simultaneously and preoperatively in cases 1, 2. AAA was diagnosed after 1.7 years and four years respectively, following the treatment of gastric cancer in cases 3 and 4. In case 1, gastric cancer with hemorrhagic complications was resected first, and aneurysmectomy was carried out on the 38th postoperative day. In case 2, a large AAA 6cm in size was wrapped first and a left upper lobectomy was done on the 19th postoperative day. In the other two patients, who were free of acertainable recurrence, aneurysmectomy was carried out in the early stage of gastric cancer in case 3, and wrapping was done in advanced gastric cancer in case.4. Case 2 died of myocardial infarction in third postoperative month. The other three patients are alive. In a patient with two life-threatening and separate diseases, surgical indications, method of the operation and priority of treatments should be carefully considered.
