To retrospectively analyze the clinical, radiolgical, and histological findings in patients with uterine leiomyomas (LU) that required surgical intervention after embolization.Between July 1999 and January 2006, we embolized 182 patients with LU. Eight of these patients subsequently required surgical resection of the tumor. We reviewed clinical data, imaging findings, embolization technique, and reasons for surgery, histological findings in the resected specimens, identification and location of the embolizing material, presence and type of necrosis in the LU, and associated pathology in adjacent organs.The 8 patients that required surgery represented 4.3% of all patients embolized for LU. Surgery was necessary due to technical failure in two patients (1.02%), complications in three (1.64%) and failed treatment in the remaining three 3 (1.64%). The mean maximum diameter of the LU was 9.8 cm (range: 4-17 cm). The mean volume of the LU was 491.88 ml (range: 30-1.365 ml) The mean age of the patients was 37.7 years (range: 28-48 years). Global necrosis was evident in 6 LU; necrosis was hyaline type in 3 and inflammatory in the remaining 3. The embolizing material was detected in the LU in one case, in the uterine myometrium in two cases, and in the ovary in one.Less than 5% of cases of LU required surgery after embolization; the risk of surgery after embolization was greater in large lesions. When the embolization technique was adequate, histological study confirmed global necrosis of the tumors, although this was not accompanied by clinical improvement. |
