Pelvic arteriovenous malformation involving the uterine and internal iliac vessels with concomitant true aneurysm of uterine artery diagnosed through color Doppler ultrasound / Philippine Journal of Obstetrics and Gynecology

Background@#Pelvic arteriovenous malformations (AVMs) are rare but carries life-threatening consequences.@*Case Report@#A 47-year-old multipara who had previously undergone four cesarean sections came for re-evaluation of a malignant ovarian new growth. She was asymptomatic. Repeat ultrasound revealed normal ovaries, and a cystic structure at the left adnexa with abundant mixing of colors, turbulent flow and pulsative waveforms on spectral Doppler. It arises from serpentine tubular structures from the uterine isthmus. Uterine artery aneurysm was considered. Magnetic resonance angiography confirmed the findings of aneurysm and pelvic arteriovenous malformation. The patient underwent a hysterectomy with ligation and excision of aneurysm. Histopathologic findings showed pelvic AVM and a true aneurysm of the uterine artery.@*Conclusion@#Ultrasound with color Doppler is a low-cost and readily available tool for gynecologists for the diagnosis and management of pelvic AVM.

A Case of Pelvic Arteriovenous Malformation / 대한산부인과학회잡지

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.

Periprostatic Pelvic Arteriovenous Malformation with Postejaculatory Hematuria / 대한비뇨기과학회지

Congenital arteriovenous malformations in the true pelvis are extremely rare : only 8 cases have been described in male patient. In most cases, the diagnosis may be obscure and the management is difficult due to frequent recurrence, so appropriate angiographic study is decisive in establishing the diagnosis and directing the mode of treatment. We report on 53 year old male patient who was treated with embolization due to congenital pelvic arteriovenous malformation with painless gross hematuria after erection or sexual intercourse. Diagnosis was established as periprostatic pelvic arteriovenous malformation by means of transrectal color Doppler ultrasonography and confirmed by angiography. Our attempt at management by embolization is described. A literature review and discussion of congenital arteriovenous malformation and worth of color Doppler ultrasonography are presented.
