RATIONALE Hepaticarterioportal fistula (APF) is a rare cause of portal hypertension and gastrointestinal hemorrhage, and presents as abnormal communication between the hepatic artery and portal vein. Percutaneous liver biopsy is a main iatrogenic cause of AFP. However, non-iatrogenic, abdominal, trauma-related APF is rarely reported. PATIENT CONCERNS A 29-year-old man presenting with severe, ...

Liver abscess after hepatic artery embolization is a rare but serious complication associated with significant morbidity and mortality. Here we report a 52-year-old case of chronic hepatitis B, liver cirrhosis and diabetes mellitus (DM) type 2 with a large gas forming liver abscess (11.4 cm) developed after transarterial chemoembolization (TACE) treatment for a large hepatocellular carcinoma (H...

This is a case of a 78-year-old male patient with multiple angiomyolipomas of a solitary right kidney. The largest of these tumors (maximum diameter: 13.4 cm) caused significant extrinsic compression of the inferior vena cava complicated by thrombosis of this vessel. Treatment of thrombosis with anticoagulants had been ineffective and the patient had experienced a bleeding episode from the larg...

conclusions in hemodynamically stable patients with a ruptured raml, early detection by ct followed by selective arterial embolization may be lifesaving. introduction renal angiomyolipoma (raml), is a rare, benign tumor arising from renal mesenchymal cells. frequently, it is asymptomatic and found incidentally. spontaneous rupture with consequent retroperitoneal hemorrhage is an uncommon but ca...

A 53-year-old woman spontaneously incurred a right trigeminal artery-cavernous sinus fistula, manifested by an intracranial bruit and right sixth nerve palsy. This lesion was successfully managed by coil embolization via the transvenous and transarterial routes.

Our aim was to describe the technique and clinical results of preoperative embolization of cervical spine osteoblastomas. We treated 3 patients with these tumors with transarterial embolization and subsequent surgical excision. In all 3 patients, distal access to the tumor-supplying vessels was gained with a microcatheter and embolization was performed with polyvinyl alcohol particles. No compl...

Cone beam CT, usually used in dental area, could easily obtain 3-dimensional images using cone beam shaped ionized radiation. Cone beam CT is very useful for direct percutaneous sac injection (DPSI) which needs very precise measurement to avoid puncture of inferior vena cava or vessel around sac or stent graft. Here we describe two cases of DPSI using cone beam CT. In case 1, a 79-year-old male...

In this issue of the AJNR, Abud and colleagues report their experience with direct percutaneous injection of cyanoacrylate for preoperative devascularization of head and neck paragangliomas (1). They achieved impressive results in nine patients, with angiographic and clinically complete devascularization in five cervical tumors. No complications related to the embolization procedure were observ...

OBJECTIVE To evaluate the safety and efficacy of transarterial nephrectomy, i.e., complete renal artery embolization, as an alternative to surgical nephrectomy. MATERIALS AND METHODS This retrospective study included 11 patients who underwent transarterial nephrectomy due to a high risk of surgical nephrectomy or their refusal to undergo surgery during the period from April 2002 to February 2...

Purpose Adjuvant coils may offer advantages in flow control during glue embolization of high flow vein of Galen aneurysmal malformation (VGAM) patients but involves specific issues such as feasibility, durability and coil mass effect. The purpose of this study is to assess the outcome of adjuvant coils in addition to transarterial glue embolization for treatment of these patients. Materials a...
