PURPOSE We report on the evolution in one institution from transarterial embolization for the treatment of dural arteriovenous fistulas of the lateral and sigmoid sinuses to the safer and more durable technique of transvenous endovascular therapy for the majority of these lesions. METHODS Arterial, venous, and combined embolizations were performed for 24 fistulas of the lateral and sigmoid si...

The pre-operative embolization of hypervascular spinal tumors is often performed to decrease intraoperative blood loss and facilitate tumor resection; however, few studies have been published on its effectiveness in giant cell tumors (GCT) of the sacrum and spine. The purpose of the present study was to investigate the value of surgical excision with pre-operative transarterial embolization for...

PURPOSE For patients with unresectable colorectal liver metastasis (CRLM), transarterial embolization with the use of drug-eluting beads with irinotecan (DEBIRI) represents a novel alternative to systemic chemotherapy or local treatments alone. The present systematic review evaluates available data on the efficacy and safety of DEBIRI embolization. MATERIALS AND METHODS A comprehensive search...

BACKGROUND AND PURPOSE DAVFs rarely involve the sphenoid wings and middle cranial fossa. We characterize the angiographic findings, treatment, and outcome of DAVFs within the sphenoid wings. MATERIALS AND METHODS We reviewed the clinical and radiologic data of 11 patients with DAVFs within the sphenoid wing that were treated with an endovascular or with a combined endovascular and surgical ap...

Hepatic arteriovenous malformations are rare congenital lesions associated with significant morbidity and mortality, most commonly from high output cardiac failure. Efficient diagnosis and treatment demands an interdisciplinary approach, and the interventional radiologist plays a pivotal role in both. Imaging is important for diagnostic accuracy and treatment planning, and transcatheter emboliz...

BACKGROUND Tuberous sclerosis complex (TSC) is an autosomal dominant disorder. It is characterized by seizures, mental retardation and hamartomatous lesions, including facial angiofibroma, subependymal giant cell astrocytoma, cardiac rhabdomyoma and renal angiomyolipoma (AML). AMLs can bleed severely in the retroperitoneal space. CASE PRESENTATION Herein, we present the case of a TSC patient ...
