Capillary malformation-arteriovenous malformation (CM-AVM) is a newly discovered hereditary disorder. Its defining features are atypical cutaneous multifocal capillary malformations often in association with high-flow lesions: cutaneous, subcutaneous, intramuscular, intraosseous and cerebral arteriovenous malformations and arteriovenous fistulas. Some patients have Parkes Weber syndrome - a lar...

Objective To describe typical clinical presentation of patients with microfistular, capillary-venule (CV) malformation as a variant form arteriovenous malformations (AVM). Methods A retrospective analysis 15 CV-AVM confirmed by computational flow model enrolled in prospective database congenital vascular between January 2008 and May 2018. Results The mean age the at first time was 30 years bala...

With the use of Tracker and Balt microcatheter systems, intravascular pressure measurements were obtained in an experimental animal model, establishing the reliability of mean blood pressure measurements from these microcatheter systems. In the experimental model, selective occlusion of branches of the external carotid artery with simultaneous pressure measurements showed significant and reprod...

BACKGROUND AND PURPOSE The purpose of this study was to determine the nature, incidence, and radiologic appearance of intracranial vascular anomalies that occur in association with periorbital lymphatic malformation (LM) and lymphaticovenous malformation (LVM). MATERIALS AND METHODS We retrospectively reviewed clinical records and imaging studies of 33 patients ranging in age from the neonata...

Arteriovenous malformations (AVMs) are part of a group of vascular anomalies which can be further sub classified into neoplasms and malformations, characterized by specific morphology, pathophysiology, clinical behaviour and management. AVMs in the oral and maxillofacial region are rare but potentially life-threatening vascular lesions. Bleeding, facial asymmetry, loose teeth and headache are c...

BACKGROUND Arteriovenous malformations (AVMs) are high-flow lesions with abnormal connections between arteries and veins without an intervening capillary bed. Infrequently, the radiographic diagnosis of a vascular lesion will not support the clinical diagnosis of an AVM. These "discrepant" lesions are not adequately captured within the current classification system and represent a treatment dil...

Cerebral aneurysms and arteriovenous malformations (AVM) are a common cause of stroke and cerebral hemorrage. Both are often discovered when they rupture, causing subarachnoid hemorrhage (SAH). SAH-induced vasospasm is mediated by enhanced vasoconstriction due to endothelin-1 (ET-1). We investigated whether endothelial cells (ECs) obtained from aneurysm and AVM express phenotypic and genotypic ...

Background and Aim: This study aimed at analyzing the demographic characteristics of the patients with non-traumatic intracranial hemorrhage, their angiographic results and the correlation between computed tomography (CT) scan and angiography findings. Methods and Materials/Patients: In a descriptive study, we retrospectively reviewed the records of the patients with non-traumatic intracranial...

Background; Endovascular embolization of cerebral arteriovenous malformations (AVM) has several benifits including AVM occlusion and flow reduction in preparation for other treatment techniques. Aim objectives; To assess the efficacy safety endovascular with different techniques materials. Patients methods; In a prospective retrospective study, 22 patients diagnosed as or fistula (AVF) underwen...

We read with great interest the article written by Alomari et al, and agree with the authors that Klippel-Trenaunay syndrome is not associated with spinal cord AVM. However, in their discussion, in relationship to spinal cord AVM with Parkes Weber syndrome, they comment briefly that “Spinal AVM has not been reported to be a feature of Parkes Weber syndrome.” Here, we demonstrate a case of Parke...
