[Aorto-iliac aneurysms and associated gastrointestinal neoplasms. Treatment problems].
In patients affected by aortoiliac aneurysm the concurrent presence of a gastrointestinal tumor is a not infrequent occurrence which poses problems of therapeutic approach (one step operation or prior treatment of one of the two diseases; in the latter case definition of timing and sequence of the surgical treatment). Three cases are reported where an eclectic therapeutic approach has enabled satisfactory results. A patient with an isolated aneurysm of right hypogastric artery associated with rectal cancer was treated with percutaneous embolization of the aneurysm and subsequent excision of the tumor. In a patient with a neoplasm of the left colon and aortic aneurysm, the aneurysm was treated first and after about a month the tumor was resected. In a patient with gastric cancer and aortic aneurysm subtotal gastrectomy was first performed and subsequently, after about 3 months, the aneurysm was treated by extraperitoneal route. Even if an unidirectional approach cannot be defined, it is thought that the two-step treatment of the associated diseases is preferable. In the presence of non stenosed non bleeding colorectal tumors it seems more suitable to treat the aneurysm first (increased postoperative risk for rupture of the aneurysm; more difficult preparation of subrenal aorta in the presence of cicatricial outcomes of colonic surgery; persistence of perianastomotic infections after colonic resection). Gastric tumors should be treated first for their higher biological aggressiveness and unfeasible correct preoperative staging. In particular cases (single unilateral aneurysm of a hypogastric artery associated with gastrointestinal cancer), non surgical treatment of the vascular lesion (embolization during angiography) is the treatment of choice.
