As both congenital (AVM) and acquired arteriovenous malformations (fistulas) may cause congestive heart failure and aneurysm formation, they should be repaired. The surgicai management of a traumatic arteriovenous fistula (AVF) is the surgical division of the fistula and primary repair of the involved artery and vem’ or the ligation of the main feeding and draining vessels.2 The anatomic locati...

Abstract Introduction To evaluate the efficacy and safety of EST, particularly foamed STS 3% in treatment arteriovenous malformations (AVMs) a single specialist centre. Methods All patients with AVMs who underwent EST from 01 January 2015–31 December 2019 were retrospectively reviewed. Types AVM grouped into Schobinger's classification. ESTs performed either foam sclerosants (STS polidocanol), ...

RATIONALE Arteriovenous malformations (AVMs) result in anomalous direct blood flow between arteries and veins, bypassing the normal capillary bed. Depending on size and location, AVMs may lead to severe clinical effects including systemic cyanosis (pulmonary AVMs), hemorrhagic stroke (cerebral AVMs) and high output cardiac failure (hepatic AVMs). The factors leading to AVM formation are poorly ...

To cite: Kumar A, Singh M, Sankhwar S. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204311 DESCRIPTION Vascular malformations (VMs) are congenital abnormalities of aberrant angiogenesis with reported prevalence of 1.2–1.5%. VMs can be either high flow (eg, arteriovenous malformation (AVM) or arteriovenous fistula (AVF)) or low flow (eg, capillary, venous, l...

Multiple arteriovenous malformations (AVM) are relatively rare, accounting for 0.3 to 4.9% of all AVMs. We describe two cases of young patients with multiple cerebral AVMs and discuss their diagnosis and treatment planning. Both patients presented with sudden headache. In patient 1, a 17-year-old female, angiography demonstrated multiple right-sided AVMs. In patient 2, a 13-year-old male, head ...

BACKGROUND Tetracyclines may be useful in preventing pathological vascular remodeling, thus decreasing the risk of spontaneous hemorrhage from brain vascular malformations. METHODS Arteriovenous malformation (AVM) and intracranial aneurysm patients undergoing noninvasive management were treated with minocycline or doxycycline (200 mg/day) up to 2 years in a prospective open-label safety pilot...

A 58-year-old Taiwanese married male presented to our emergency department with progressive dizziness and generalized weakness for 1 week. His blood pressure was 138/91 mmHg and heart rate was 74 bpm. He stated that nosebleeds occurred off and on for more than 20 years, and he had been diagnosed pulmonary arteriovenous malformation (AVM) and received coils embolization in April, 2009 (Figure 1a...

Vascular anomalies affect up to 10% of newborns, largely because of the high incidence of hemangioma of infancy. Vascular anomalies also frequently occur in adults; there is high prevalence of capillary malformations (0.3%). These cutaneous stains often cause psychosocial problems related to their visibility. Venous malformations occur in the skin and in internal organs and may cause destructio...

scalp is an abnormal connection between the feeding arteries and draining veins, without the normal capillary bed in the subcutaneous layer of the scalp. The draining veins may be grossly dilated and tortuous, and may show variceal dilatation (1-5). It is generally thought that AVM arises from multiple developmental defects causing the primitive capillary bed to fail to persist (6, 7). It is al...

BACKGROUND AND PURPOSE Although phase-contrast MR angiography provides some information regarding hemodynamics of cerebral arteriovenous malformations (AVMs), most conventional MR angiographic techniques have not been helpful in this respect. We attempted to determine the value of MR digital subtraction angiography (DSA) in assessing AVM hemodynamics. METHODS We developed an MR DSA technique ...
