A Case of Pelvic Arteriovenous Malformation / 대한산부인과학회잡지

ABSTRACT

Arteriovenous malformation of the female pelvis is a rare condition, and its diagnosis, classification, and treatment are still sources of considerable confusion. Now, multidisciplinary and individualized approaches with the use of modern interventional radiologic technology are stressed and play an important role in the management of female pelvic arteriovenous malformation. We experienced a patient, 28-year0old woman with a uterine arteriovenous malformation presenting with irregular vaginal bleeding. At physical examination the slightly enlarged uterus was found, but no other abdominal or cardiopulmonary abnormalities were found. Diagnosis was established by angiography and contrast-enhanced CT/MRI scan. The patient underwent preoperative intra-arterial embolization to decrease operative morbidity and facilitate complete removal. Hysterectomy and resection of surrounding tissue was done successfully. Pathologic examination showed that the uterine myometrium was involved by the arteriovenous malformation and it was composed of fat and fibrous tissues with shick-walled and dilated blood vessels of various diameter. Now we report a case of arteriovenous malformation with a brief review.
