Description

Saccular aneurysms are more vulnerable to rupture than fusiform aneurysms ; the occurrence of rupture increases the mortality rate, even if emergency surgery is performed.<BR>An 85-year-old woman who experienced sudden onset of left flank pain and vomiting was transported to our hospital. She had a history of hypertension, diabetes mellitus, hyperlipidemia, and angina pectoris. Contrast-enhanced abdominal computed tomography revealed a ruptured abdominal aortic aneurysm (48 mm in diameter) arising from the anterior wall of the terminal aorta and massive retroperitoneal hemorrhage spreading above the left renal artery. The aneurysm was classified as Fitzgerald type III. The patient was immediately transferred to the operation theater. Initially, artificial vascular grafting was planned ; however, the patient developed progressively worsening circulatory collapse. Furthermore, severe adhesions were observed around the terminal aorta. Therefore, the patch closure technique was applied to close the mouth of the saccular aneurysm in order to control the bleeding. After the procedure, the bleeding gradually ceased, the patient recovered from the circulatory shock, and the operation was successfully completed. The patient remained relatively stable after the operation. On postoperative day 23, she was discharged without any serious complications.
