Prognosis of 16 patients with hepatic tumors and angiographically proven arterioportal fistulas was analysed in relation to treatment. Six patients received only conservative therapy; they all died of variceal bleeding in the course of two months after angiography. Hepatic resection was performed in four patients; three of them are still alive 13-52 months later including two free of both the tumor and portal hypertension. Hepatic artery embolization was carried out in six patients. All of them died in 2-36 months after the procedure, but only two from gastroesophageal hemorrhage.It is concluded that prognosis of arterioportal fistulae in liver neoplasms is poor due to hyperkinetic portal hypertension and following variceal bleeding. Hepatic resection of both the tumor and the fistula is the treatment of choice. In unresectable cases hepatic artery embolization will decrease the risk of variceal hemorrhage.

“…The use of guidewires as a matrix to nestle in coils for embolization have been previously described in the embolization of giant pulmonary artery aneurysms and visceral arterio-venous fistulas. 8,9 While using the guidewires to pack the aneurysm in our case, initially the decision was taken to use a long enough segment of the guidewire to allow it to coil within the sac and provide a scaffolding for subsequent coiling. There is a risk of arterial wall erosion by the guidewire owing to the stiffness of the inner nitinol core.…”

Splenic artery aneurysms are among the more frequently diagnosed intra-abdominal aneurysms and are not infrequent in patients with raised portal venous pressure often requiring endovascular or surgical therapy. A 36-year-old female patient with Non-cirrhotic portal fibrosis and portal hypertension was diagnosed with multiple large splenic artery aneurysms for which she was initially operated which resulted in substantial blood loss during dissection that required embolotherapy. Initial attempts at coil embolization proved unsuccessful due to the wide aneurysmal neck and flow characteristics. Following which the aneurysmal sac was packed with multiple guidewires to act as a scaffold for further coil embolization. Subsequently, hemostasis was achieved and the patient underwent splenectomy later thereby demonstrating that embolization of large aneurysms can be accomplished with reasonable efficacy using guidewires.
