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 ...

Introduction: Arteriovenous malformations (AVMs) are uncommon vascular lesions that can arise in any part of the body. Case Report: In this case study, we presented a huge AVM of the upper lip in a 70-year-old man that he noticed since 5years ago with slow growth in this period. Computed tomography angiography revealed a large AVM with feeders from the right...

Background Chronic subdural hematoma is associated with high rates of perioperative complications and recurrence. Methods The classic treatments are observation or surgical evacuation. Middle meningeal artery embolization a recently emerging procedure that has evolved as the neuroendovascular community gained collective experience. This review summarizes pathophysiology chronic hematoma, review...

Vascular anomalies are categorized into vascular tumours or vascular malformations on the basis of clinical features and histopathology. The literature regarding high flow arteriovenous malformations of the auricle is rare. A case of a patient clinically diagnosed with an arteriovenous malformation of the external ear and was managed with preoperative embolization, surgical excision and reconst...

OBJECTIVES We evaluated the anatomic and technical factors predicting stent malposition and embolization in patients undergoing endovascular stent implantation for relief of noncoronary vascular obstruction. BACKGROUND Endovascular stent implantation provides a highly effective, minimally invasive solution to vascular obstruction in patients with structural heart disease. However, stent impla...

BACKGROUND AND PURPOSE A noninvasive investigation with high spatial resolution and without metal artifacts is necessary for long-term imaging follow-up after flow-diverter implantation. We aimed to evaluate the diagnostic value of conebeam CT angiography with intravenous contrast enhancement in the assessment of vascular status following implantation of the Pipeline Embolization Device and to ...

Embolization is a remarkably versatile procedure used in nearly all vascular and nonvascular systems to treat a wide range of pathology. The published literature is rich with studies demonstrating the enormous therapeutic potential offered by embolization procedures, and the possibilities continue to expand with the advent of new embolization agents and techniques. Unfortunately, with this vari...

OBJECTIVES To evaluate the use of a new tumor embolization agent, Onyx (Covidien, Dublin, Ireland), for the use of intraoperative embolization of a sinonasal unclassified spindle cell sarcoma. METHODS A 45-year-old female patient presented to the rhinology clinic with a nasal mass. A biopsy revealed a highly vascular mass consistent with a sinonasal unclassified spindle cell sarcoma. Secondar...

BACKGROUND We report two cases of vascular complications after reconstructive pelvic surgery successfully treated with pelvic artery embolization. CASES Two patients who underwent mesh placement complicated by postoperative pelvic hemorrhage were treated successfully with selective arterial embolization. CONCLUSION The widespread adoption of reconstructive pelvic surgery procedures with dis...
