BACKGROUND AND PURPOSE Embolization of a spinal cord arteriovenous malformation (SCAVM) is still considered risky. We evaluated the efficacy and reliability of pharmacologic provocative testing with neurophysiologic monitoring in the embolization of SCAVMs. METHODS We retrospectively analyzed results of 60 provocative tests during 84 angiographic procedures (in 52 patients) with intended endo...

BACKGROUND The safety and survival benefit of transcatheter arterial chemoembolization for patients with huge hepatocellular carcinoma is uncertain. AIM To evaluate the role of embolization in unresectable hepatocellular carcinomas larger than 10 cm. METHODS Twenty-six consecutive patients who had an unresectable hepatocellular carcinoma larger than 10 cm and refused aggressive treatment, w...

Gas exchange following experimental pulmonary thromboembolization was studied with an inert gas elimination technique in 17 dogs. Pulmonary arterial, systemic arterial, and expired gas concentrations of six gases infused intravenously were measured before embolization and 5, 10, 15, 30, 60, and 120 minutes after embolization. Distributions of ventilation-perfusion (VA/Q) ratios were derived fro...

Abstract Background Osteoarthritis (OA) is a leading cause of chronic knee pain and disability with reported prevalence 25–30% the population. Knee OA has traditionally been thought as degenerative disease only related to repetitive injury “wear tear” mechanism, yet it now considered much more complex inflammatory nature induced by cytokines mediators through abnormal neo-vascularization (angio...

We report a case of a patient who developed a remote dural arteriovenous fistula involving the left sigmoid sinus 4 months after successful transarterial embolization of a carotid cavernous fistula. This rare occurrence has been reported after transvenous embolization, but this represents the first case, to our knowledge, after transarterial coil embolization. We present our findings along with...

background: percutaneous nephrolithotomy (pcnl) for renal calculi is less invasive treatment than open surgery. vascular complications of this procedure include hematoma, pseudoaneurysm and arteriovenous fistula of which pseudoaneurysm is usually symptomatic 24h after procedure. case report : we report a case of pseudoaneurysm, which was symptomatic within less than 24h following procedure and ...

PURPOSE To assess the toxicity and efficacy of chemoembolization and bland embolization in patients with neuroendocrine tumor metastases to the liver. MATERIALS AND METHODS A total of 67 patients underwent 219 embolization procedures: 23 patients received primarily bland embolization with PVA with or without iodized oil and 44 primarily received chemoembolization with cisplatin, doxorubicin, ...

Nonbacterial thrombotic endocarditis (NBTE) is a valvular disorder commonly associated with malignancy and connective tissue diseases. While the often discovered during autopsy, it sometimes diagnosed in patients who present systemic embolization. Here, we discuss case of 52-year-old female, disease malignancy, presented symptoms embolization was NBTE by transesophageal echocardiogram (TEE). Th...

BACKGROUND AND PURPOSE The techniques of preoperative embolization of hypervascular spinal tumors, which has been known to be helpful for completing tumor resection, have not been described in detail. The purpose of this study was to analyze the technique and to evaluate the safety and value of preoperative transarterial embolization of hypervascular spinal tumors. METHODS Eighteen patients w...
