Abstract:

Background The International Society for the Study of Vascular Anomalies (ISSVA) categorizes vascular anomalies into vascular tumors and vascular malformations. Vascular malformations are further divided into slow-flow (venous, lymphatic, and capillary malformation) and fast-flow malformations (arteriovenous malformation and arteriovenous fistula). This interdisciplinary classification has therapeutic implications. Methods The objective of this article is to provide concise information about the current terminology and treatment strategies of peripheral vascular malformations, based on the cur

Abstract:

Arteriovenous malformation (AVM) results from errors in vascular development during embryogenesis; absent capillary beds lead to shunting directly from the arterial to venous circulation. Although it is common in the head and neck region, Arteriovenous malformations (AVM) of the external ear are relatively uncommon lesions. They typically present during childhood. We report a case of giant AVM of the right pinna in 8 years child, which are very rarely seen. We discussing the definition, clinical findings, diagnostic approaches of arteriovenous malformations.

Abstract:

Klippel-Trénaunay syndrome (KTS) is a rare vascular congenital anomaly affecting less than 200,000 people in the United States. Vascular malformations associated with KTS tend to affect slow flow systems: venous, capillary, and lymphatic systems. The nature of the syndrome leads to a higher risk for the development of arteriovenous malformations. Our case presentation describes a patient with KTS and an associated rare presentation of intraventricular arteriovenous malformation (AVM).

Arteriovenous malformations are one of the variants of congenital vascular malformations resulting from a defect in the development of the arterial and venous systems with the formation of direct messages between vessels of different diameters and shunting of blood with high velocity characteristics from the arterial to the venous part of the vascular system. Arteriovenous malformations are characterized by a wide variety of clinical manifestations and in some cases may be accompanied by severe circulatory disorders.

Arteriovenous malformations (AVMs) are clusters of abnormal arteries and vessels connected by one or more direct connections called fistula or shunt. AVM can occur in any part of the body. Pancreatic arteriovenous malformation (P-AVM) can be defined as an abnormal vascular network that develops from one or more feeding arteries, dilates early drainage vessels, and forms an arteriovenous shunt. In this paper, we wanted to represent a 45-year-old male patient admitted to our hospital due to abdominal pain with a case of AVM and a review of the literature.

Arterial venous malformations (AVM) of the uterus are uncommon entities and should be considered in patients who present with profuse genital bleeding. There are two types of uterine AVM: acquired and congenital. Acquired uterine AVMs are conformed by communications between the uterine arteries and the myometrial veins, and are caused by an iatrogenic event or a pathological condition. Congenital AVMs are the result of abnormal development of primitive vessels that result in connections between pelvic arteries and veins in the uterus without an interconnecting capillary bed.

Abstract Arteriovenous malformations (AVM) are vascular abnormalities, most often presenting significant risk of massive bleeding and being lethal for the patient. Thus, the knowledge of these lesions must be adequate for both the clinical and the oral radiologists. In this paper we describe the medical history of a young woman with a massive arteriovenous malformation localized at the left side of the mandible.

Abstract:

Pilocytic astrocytomas are highly vascular, relatively common primary brain tumors in the pediatric population, but their association with a true arteriovenous malformation (AVM) is extremely rare. We describe an eight-year-old girl with a right supratentorial juvenile pilocytic astrocytoma (WHO grade I) with an angiographically documented AVM entangled in the tumor mass who presented with intracranial hemorrhage due to a ruptured anterior choroidal artery pseudoaneurysm encased in the lesion. The AVM nidus as well as the hemorrhage site was embolized with Onyx. A literature review revealed on

Abstract:

Arteriovenous malformations (AVM) of the intestine are rare causes of gastrointestinal bleeding. Diagnosis depends upon accurate interpretation of imaging features and histopathology to differentiate them from other vascular malformations. Presentation of colonic AVM with mucous diarrhea and pain is rare and poses diagnostic challenges. Usually, patients presenting with bleed need surgical intervention. The current report discussed one patient with chronic liver disease, extrahepatic portal vein thrombosis with small bowel AVM and two patients with colonic AVM, highlighting management strategi

<strong>Abstract</strong> Vascular malformations belong to the spectrum of orphan diseases involving all segments of the vascular tree: arteries, veins and capillaries, and similarly the lymphatic vasculature. These malformations are a common cause of soft tissue masses and often referred for ultrasonographic evaluation. The ultrasonographic and doppler imaging findings can help to categorize these malformations into slow-flow or fast-flow lesions which forms the basis of further workup and management. Further evaluation with magnetic resonance imaging (MRI) or computed tomography (CT) helps i

Abstract:

Scalp masses are not infrequently encountered in daily clinical practice. They are represented by a wide spectrum of different clinical entities and are usually managed by an excision or by simple observation. Although it happens rarely, head lumps may hide an underlying cranioencephalic malformation that has to be preoperatively diagnosed to perform an appropriate treatment. Cerebral arteriovenous malformations (AVMs) are not included among the intracranial malformations connected with a scalp mass.

Abstract:

Abstract A compartmental conceptualization of intracranial arteriovenous malformations (AVMs) allows recognition of feeding arteries, an intervening plexiform nidus, and draining veins. AVM therapy involves eliminating the nidus, which is the source of hemorrhage, without compromising normal arterial and venous drainage of the brain. Traditional methods of AVM therapy through microsurgery and endovascular embolization involve arterial devascularization, with preservation of AVM venous drainage, until the nidus is excluded. The transvenous approach in treating vascular malformations was popular

Abstract:

Although cerebral vascular malformations are traditionally considered to be congenital lesions, they often become clinically evident in the 3rd to 4th decades of life, leading to the assumption of a long silent clinical period. Unlike vein of Galen malformations, antenatal diagnosis of cerebral arteriovenous malformations (AVMs) is highly uncommon. Postnatal development of an AVM is an emergent concept supported by more clinical observations. Genetic and biological studies demonstrate that an environmental trigger (“second hit”) in addition to genetic predisposition may be a key in understandi

The patient underwent surgery and we performed total resection of the AVM. The particularity of this case is the rare possibility of outcome with regression of the vascular malformation.

Conventional treatment options such as surgery and endovascular therapy often are insufficient for cure. There is a growing body of knowledge on the genetic and molecular underpinnings of AVM development and maintenance, making the future of precision medicine a real possibility for AVM management.

Brain arteriovenous malformations (AVMs) are anomalous direct shunts between cerebral arteries and veins that convalesce into a vascular nidus. The treatment strategies for AVMs are challenging and variable. Intracranial hemorrhage and seizures comprise the most common presentations of AVMs. However, incidental AVMs are being diagnosed with increasing frequency due to widespread use of noninvasive neuroimaging. The balance between the estimated cumulative lifetime hemorrhage risk vs the risk of intervention is often the major determinant for treatment. Current management options include surgic

The problematic cases are diffuse AVMs infiltrating structures that render them impossible to totally extirpate surgically without causing much blood loss and tissue damage.
