Résumé
Between 1987 and 2002, 22 internal iliac artery aneurysms in 14 patients were repaired. In 13 we performed aneurysm excision or reconstruction. There were 3 cases in which simple proximal ligation of the internal iliac artery was performed; in 2 of these CT scans confirmed that the reduction of the internal iliac artery aneurysms was not recognized, but blood flow was not shown in the aneurysm. However, 6 years postoperatively 1 patient was confirmed with an expansion of the aneurysm, and blood flow was seen on a CT scan. In the 2 latest patients, the blood pressure of the internal iliac artery was measured before and after proximal clamping of the internal iliac artery, but the blood pressure of aneurysms could not be fully lowered by proximal ligation of the internal iliac artery. Therefore, endoaneurysmorrhaphy seemed to be the operative method of choice for treatment of the internal iliac artery aneurysms.
Résumé
An 83-year-old female was referred to our hospital because of a swelling and pain of the left lower extremity. An endoaneurysmorrhaphy and bypass surgery between the left common iliac artery and the external iliac artery were performed under the diagnosis of deep vein thrombosis associated with a left isolated internal iliac aneurysm. Forty patients with isolated internal iliac aneurysm were reported in Japan and deep vein thrombosis occurred only in our patient. The external growth of the aneurysm behind the external iliac artery might cause compression, congestion and phlebitis of the common iliac vein, resulting in deep vein thrombosis.
