BACKGROUND AND PURPOSE The treatment of epistaxis in patients with hereditary hemorrhagic telangiectasia can be very challenging. The purpose of our study was to evaluate our experience with endovascular epistaxis embolization in patients with hemorrhagic hereditary telangiectasia and to compare this with our experience in patients treated for idiopathic epistaxis. MATERIALS AND METHODS Over ...

introduction: traumatic arteriovenous fistula (avf) called to an abnormal relationship between artery and vein which occurs in 10% of arterial traumas. if treatment of avf due to trauma delayed, different outcomes including heart failure, varices and varicose ulcers may accure. in case of chronic traumatic avf, open surgery may lead to remarkable outcomes, presence of many lateral veins and var...

PURPOSE To report on our clinical experience with and the success rate and safety of percutaneous transcatheter embolization with N-butyl cyanoacrylate (NBCA) as the lone primary embolic agent used for arterial embolization of hemorrhagic liver lesions. MATERIALS AND METHODS This retrospective study enrolled all patients who presented to the emergency room with hemorrhagic liver lesions durin...

BACKGROUND Oxygen-derived free radicals are thought to injure the ischemic heart during coronary microvascular embolization. METHODS AND RESULTS To test this idea, microspheres (15 microns in diameter) were repetitively administered into the left anterior descending coronary artery to cause microvascular embolization in dogs. Myocardial contractile and metabolic dysfunctions were significantl...

Abstract Embolization is a fundamental procedure that interventional radiologists perform on daily basis to treat variety of diseases. The disease processes for which embolization considered safe and effective treatment are continuously expanding, as the materials available use. To achieve optimal clinical outcomes minimize complications, it imperative radiologist understands properties, streng...

BACKGROUND AND PURPOSE Cyanoacrylates are effective occlusive agents in neurovascular interventions. To study their potential to improve long-term results of endovascular treatment of aneurysms, we conducted experimental studies in canine aneurysm models. METHODS Venous pouch carotid aneurysms were constructed in dogs. Results of coil embolization of lateral wall and bifurcation aneurysms wer...

OBJECTIVES/HYPOTHESIS To characterize contemporary treatment of head and neck paragangliomas and the effect of treatment on postoperative complications, length of stay, and costs. STUDY DESIGN Retrospective cross-sectional study. METHODS Discharge data from the Nationwide Inpatient Sample for 7,791 patients who underwent endovascular or surgical treatment of head and neck paragangliomas bet...

Cholesterol embolization syndrome refers to embolization of the contents of an atherosclerotic plaque (primarily cholesterol crystals) from a proximal large-caliber artery to distal small to medium arteries causing end-organ damage by mechanical plugging and an inflammatory response. Synonyms used in the medical literature include atheromatous embolization, cholesterol crystal embolization, and...

OBJECTIVE Periprocedural intracranial hemorrhage secondary to intranidal flow redirection may develop after arteriovenous malformation (AVM) embolization. We hypothesized that continuous draining vein pressure monitoring may identify clinically relevant hemodynamic changes during devascularization. Our goal was to characterize the draining vein pressures in a swine rete mirabile AVM model durin...

Objectives: Since 2018, we have routinely placed an Amplatzer vascular plug (AVP) in the proximal left subclavian artery (LSCA) to prevent embolic events during thoracic endovascular aortic repair with arch vessel debranching (d-TEVAR). Type II endoleaks of LSCA origin were observed two patients (20%), and coil-in-plug (CIP) method, i.e., microcatheter insertion through addition coil embolizati...
