Arteriovenous malformations are uncommon congenital disorders in vascular development. They frequently involve craniofacial structures and result in a morphogenic abnormality with ominous arteriovenous shunting. We present a huge AVM of the upper lip in an 18-year-old patient who was successfully treated by the combination method of presurgical endovascular embolization and complete resection of the lesion. Subsequent surgical defect in upper lip, which involved more than two-third of the lip length, was reconstructed via Webster's modification of cheek advancement flap...

Arteriovenous malformation (AVM) of the head and neck is a rare and potentially life threatening entity due to massive haemorrhage. There are several indications for treatment, including age of the patient and location, extent and type of vascular malformation. Endovascular therapy can effectively cure most lesions with limited tissue involvement. Surgery can be used in selected cases in combination with embolization. Here we report the case of a young woman affected by a massive AVM on the left side of the mandible and submandibular region, and also review the literature on AVM with special attention to treatment strategies...

BACKGROUND: The purpose of our report is to describe an innovative system used for mandibular immobilization during Gamma Knife surgery (GKS) procedures. It is based on an approach originally developed in Marseille in extracranial lesions, close to or involving the mandible, which may imply a certain degree of movement during the therapeutic image acquisitions and/or GKS treatment. METHODS: The maxillofacial surgeon applied bone titanium self-tapping monocortical screws (4; 2 mm diameter, 10 mm length) between roots of the teeth in the fixed gingiva (upper and lower maxillae) the day before GKS (local anesthesia, 5-10 min time)...

Neurovascular emergencies, consisting of acute ischemic stroke, non-traumatic aneurysmal subarachnoid hemorrhage, arteriovenous malformation, dural arteriovenous fistula, and carotid- cavernous fistula, can have an acute presentation to the emergency department. Radiologists should have an understanding of these processes and their imaging findings in order to provide a prompt and accurate diagnosis. Neurointerventional radiology plays a critical role in providing additional diagnostic information and potentially curative treatment...

By conducting a systemic search of the PubMed database, we performed a comprehensive literature review to characterize secondary gliomas following radiotherapy treatment and to determine the most appropriate treatment strategy. Our analysis included 296 cases of radiation-induced gliomas. The primary lesion was characterized as a hematological malignancy in 104 cases (35.1 %), pituitary adenoma in 35 (11.8 %), craniopharyngioma in 19 (6.4 %), medulloblastoma in 38 (12.8 %), germ cell tumor in 13 (4.3 %), low-grade glioma in 28 (9...

Uterine arteriovenous malformation (AVM) is defined as abnormal and nonfunctional connections between the uterine arteries and veins. Although the patients typically present with vaginal bleeding, some patients may experience life-threatening massive bleeding in some circumstances. The treatment of choice depends on the symptoms, age, desire for future fertility, and localization and size of the lesion; however, embolization of the uterine artery is the first choice in symptomatic AVM in patients at reproductive age with expectations of future fertility...

Arteriovenous malformation (AVM) is a structural vascular abnormality in which the arterial vasculature connects with the venous vasculature without capillary connections. AVM confined to the nasal cavity is considerably rare. Blurred vision can be one of the associated symptoms. A combined approach of complete surgical resection with prior superselective embolization is the treatment of choice. Following resection, the reconstruction of facial defects, particularly in the nasal area, is challenging. The present study reports the rare case of a patient with an AVM in the nasal cavity, in which embolization, resection and flap reconstruction were performed...

Arteriovenous malformations (AVMs) are a high-flow form of a vascular malformation, which can be found anywhere in the body. While historically treated surgically, a multidisciplinary approach utilizing multiple specialties and treatment modalities is now commonly employed. In order to effectively treat an AVM, the nidus must be targeted and eradicated, which can be done via multiple approaches. We present the case of a 43-year-old male with a gastric wall AVM, which was initially incompletely treated using a percutaneous transarterial approach...

INTRODUCTION: Embolisation has long been used as an adjunct to surgical resection in the treatment of brain arteriovenous malformation (bAVM). The most commonly used embolic material, n-butylcyanoacrylate glue, requires experience and skill to handle its quick and unpredictable flow and polymerisation. A new liquid embolic agent, ethylene vinyl alcohol copolymer (Onyx), is less adhesive and polymerises slowly, which provides better control for radiologists performing embolisation. OBJECTIVE: To report our experience in embolisation using Onyx alone or in combination with histoacryl for bAVM embolisation in our tertiary referral centre...
