Background: Spinal dural AVF is the most common type of spinal vascular malformation. However, presenting symptoms differ according to site of spinal involvement. This study described a case of arteriovenous malformation with paraparesis and incontinence. Case Presentation: Diagnosis of patient was confirmed by clinical and imaging examination using magnetic resonance image and ruling out ot...

Venous malformations have static venous lakes that predispose to spontaneous venous thrombosis within the malformation due to its low-flow static state. Thrombi of varying sizes can then embolize continually into the pulmonary arterial circulation, and occlude and narrow elastic pulmonary arteries causing chronic thromboembolic pulmonary hypertension (CTEPH). Pulmonary thromboendarterectomy (PT...

Chronic femoral vein compression (May-Thurner Syndrome) is a known rare cause of deep venous thrombosis. Subsequent angiogenesis and the development of arteriovenous malformation (AVM) in the setting of chronic venous thrombosis is by itself a rare and poorly understood phenomenon. We report a case in which elevated venous pressures resulting from such compression appear to have resulted in the...

Abstract A rare case of a pulmonary arterio-venous malformation not requiring treatment is reported. An incidental peripheral right lower lobe intrapulmonary was identified on computed tomography. On catheter angiography, no artery supply identified. Systemic arteriography systemic arterial from conjoined inferior phrenic with venous drainage to the left atrium. Due this lung abnormality being ...

Introduction: Retinal arterio-venous malformations (AVMs) are rare, congenital, high-flow congenital developmental vascular anomalies without intervening capillary bed also known as racemose angioma, They unilateral, nonhereditary lesions located anywhere in retina and may involve optic nerve.
 Case report: A 55 year old male was found to have abnormal malformation over nerve head his left...

OBJECTIVES To re-evaluate the fluoroscopic findings of venous malformation by cine mode cisternography. METHODS Using direct injection cine-cisternography, we studied 49 venous malformation lesions in the head and neck of 30 patients who were scheduled to undergo ethanol sclerotherapy. The diameter of definitively measurable 46 lesions was 21.7 ± 10.5 mm (mean ± SD, range: 6.0-48.0 mm). The i...

A 13-year-old girl had a venous malformation at her abdductor pollicis longus muscle of right forearm, with clinical presentation of local swelling, tenderness and inability to abduct her thumb. Under sonographic guidance, we treated this lesion with percutaneous intralesional ethanol injection. Her symptoms soon resolved after the treatment. In a follow-up period of 8 months, persistently decr...

Objective: To compare the diagnostic value between magnetic resonance diffusion-weighted imaging (MRDWI) and computed tomography (CT) for hemangioma and venous malformations of head and neck among children. Methods: A total of 55 subjects were systematically recruited into this study, including 25 cases diagnosed with hemangioma and 30 cases with venous malformation. Diagnostic test was applied...
