PURPOSE To evaluate the technical feasibility and clinical outcome of bilateral uterine artery embolization (UAE) as a first-line therapeutic option for bleeding uterine arteriovenous malformation (AVM). MATERIALS AND METHODS Between 2002 and 2012, 19 patients were diagnosed with acquired uterine AVM clinically and through imaging studies. The clinical characteristics, angiographic features, ...

PURPOSE To determine whether hemangioblastomas, highly vascular tumors requiring surgery that is potentially complicated by excessive bleeding, can be embolized safely by using interventional techniques that furnish a more avascular surgical field. METHODS Nine hemangioblastomas involving either the cerebellum or the spinal cord were embolized preoperatively. In each case the feeding artery w...

Onyx Liquid Embolic System (LES) embolization of highly vascular lesions is becoming more frequently used as an adjuvant therapy prior to surgical resection. The authors present a case of a successful pre-operative embolization of a glomus jugulare tumor using Onyx LES. The patient returned for scheduled operative resection one week later. Immediately following the surgery, the patient experien...

1. The clinical indication of BAE in acute major haemoptysis has been well accepted as it might be life-threatening if not promptly controlled. However, the usefulness of BAE in chronic recurrent haemoptysis (defined by the authors as having two episodes within 6 months) is questionable. If the authors wanted to assess the safety and effectiveness of this approach, it would appear more logical ...

Therapeutic embolization is an effective and relatively safe method for managing many cases of head and neck trauma. In the last 5 years, 78 traumatic vascular lesions--10 arterial transections and 68 arteriovenous fistula--were treated by intravascular embolization at four medical centers. Selection of embolic materials is discussed and different types of lesions are illustrated. Treatment was...

There are several options for the treatment of varicocele, including surgical repair either by open or microsurgical approach, laparoscopy, or through percutaneous embolization of the internal spermatic vein. The ultimate goal of varicocele treatment relies on the occlusion of the dilated veins that drain the testis. Percutaneous embolization offers a rapid recovery and can be successfully acco...

Bronchial artery aneurysm (BAA) is a rare vascular phenomenon. This review highlights a case of a BAA that was complicated by the presence of a bronchial artery to pulmonary artery (BA-PA) fistula, consequently presenting a unique challenge to management. BAAs have a strongly reported risk of rupture resulting in life-threatening hemoptysis. Embolization has thus become routine for the manageme...

Objective: During cerebral aneurysm embolization using intracranial stents, platelet aggregation increases owing to increased wall shear stress and a loss of vascular endothelial function at the stent implantation site. Preoperative multiple antiplatelet therapy was introduced prevent severe thromboembolic complications due aggregation. However, specific guidelines for administration pharmacolo...

Uterine necrosis is one of the rarest complications following pelvic arterial embolization for postpartum hemorrhage (PPH). With the increasing incidence of cesarean section and abnormal placental localization (placenta previa) or placental invasion (placenta accreta/increta/percreta), more and more cases of uterine necrosis after embolization are being diagnosed and reported. Pelvic computed t...

Unicentric Castleman's disease is a rare, benign lymphoproliferative disorder that is curable with surgical resection. However, significant bleeding often occurs during surgery because of tumor hypervascularity. We herein present a case of hyaline-vascular-type mediastinal unicentric Castleman's disease, successfully resected using video-assisted thoracoscopic surgery with preoperative emboliza...
