Aneurysms of the internal iliac artery

Iliac Artery Aneurysms Presenting as Large Pelvic Masses

“…Swelling of the extremities secondary to venous obstruction may also be a presenting finding. (Short 1966) There may be a difference in the distal extremity pulses in unilateral aneurysms.…”

“…50 to 80% of these aneurysms if not treated will progress to rupture. (Short 1966) These most commonly rupture into the retroperitoneal space and are associated with perianal ecchymosis. (Baron et uli983) They may also rupture into the genitourinary or GI tract.…”

Isolated internal iliac artery aneurysm eleven years after tube graft repair of an abdominal aortic aneurysm: Case report and literature review

“…No specific data are available regarding the comparative risk of rupture of an internal iliac vs a common iliac aneurysm. Mortality rates for ruptured iliac aneurysms are high and reported as ranging from 29% to 80% [5,8,9,14,19]. Ultrasonography, CT and magnetic resonance imaging (MRI) have all been used for detecting internal iliac aneurysms.…”

“…Treatment is surgical and consists of either ligation of the neck of the aneurysm or obliterative endoaneurysmorrhaphy. Complete excision of the aneurysm is rarely to be considered as it is fraught with danger of deep pelvic vascular injury or retraction of branches of the internal iliac artery, which leave the pelvis through the sacral and sciatic tbramina, resulting in massive, or even uncontrollable hemorrhage [9,19]. Ligation of the neck of the aneurysm alone may not be curmive as demonstrated by Nachbur et al [22] who described continued expansion of internal iliac aneu-D~sms in three of four patients treated by simple ligation of the neck of the hypogastric aneurysms at the time of repair of four ruptured abdominal aortic aneurysms.…”

Ureteric Obstruction of Solitary Kidneys by Aneurysms of the Iliac Artery

“…An internal iliac aneurysm, if it has a neck, may be simply ligated. If it is very large, total excision should be avoided as it is difficult to obtain distal control; in this situation partial excision and obliteration of the remnant are advisable (Kirkland and Starr, 1953;Short, 1966;Wirthlin and Warshaw, 1973). If an internal iliac aneurysm is found incidentally it is recommended that it is ligated only.…”
