This case series aimed to review the significance of revisiting papilledema after successful cerebral venous sinus thrombosis (CVST) management with sinus angioplasty. Four patients presented with blurring and transient obscuration of vision with papilledema, headache, tinnitus, and vomiting. On magnetic resonance venography and digital subtraction angiography, chronic transverse sinus thrombosis was diagnosed for which patients underwent endovascular intervention (stenting). After the resolution of CVST, patients developed the recurrence of symptoms which on digital subtraction angiography revealed dural arteriovenous malformation (DAVM)...

Intracranial endovascular interventions provide effective and minimally invasive treatment of a broad spectrum of diseases. This area of expertise has continued to gain both wider application and greater depth as new and better techniques are developed and as landmark clinical studies are performed to guide their use. Some of the greatest advances since the last American Heart Association scientific statement on this topic have been made in the treatment of ischemic stroke from large intracranial vessel occlusion, with more effective devices and large randomized clinical trials showing striking therapeutic benefit...

The modern application of interventional radiology techniques is revolutionizing the treatment of the vascular malformations of the head and neck. In fact, the morbidity related with the surgical extirpation of the malformation might be drastically reduced with the use of an endovascular approach. The present report describes the case of a 11 years old male affected by a large intraosseous arteriovenous malformation of the mandible. The coil embolization of the main drainage vein caused the spontaneous regression of the lesion and avoided a mutilating surgery and severe psychological sequels...

Rendu-Osler-Weber disease, also known as hereditary hemorrhagic telangiectasia, is a rare autosomal dominant disorder which is often characterized by recurrent epistaxis, mucocutaneous and gastrointestinal telangiectasias, and visceral arteriovenous malformations. Patients with gastrointestinal involvement can present with a wide spectrum of severity, which may vary from uncomplicated iron deficiency anemia to continuous and refractory bleeding. We present the case of a 62-year-old female, who was admitted with anemia following several episodes of melena, and whose endoscopic examination revealed multiple angiodysplasias in the stomach and small bowel...

The video demonstrates resection of a Grade II Spetzler-Martin unruptured, medium-sized arteriovenous malformation (AVM). A young woman presented with headaches and seizures. The right frontal lesion measured 4.5 cm in largest dimension and had superficial venous drainage. Partial Onyx embolization, primarily of the anterior cerebral feeding arteries, was performed. Bone removal for exposure allowed identification of indentation from the large superficial draining vein. The video demonstrates careful microsurgical dissection on the AVM/brain interface, with selective interruption of feeding arteries circumferentially...

Vein of Galen aneurysmal malformation (VGAM) is a rare angiopathy, which most commonly presents in infancy. Although very rare, it is associated with high morbidity and mortality rates. In order to minimize such morbid rates, a prompt diagnosis followed by a timely initiation of management is crucial. Multiple antenatal and postnatal imaging techniques for the diagnosis have been described and discussed in the literature. However, to our knowledge, a comprehensive review exploring such a list of imaging options for VGAM has never been established...

INTRODUCTION: There is increasing acknowledgement that surgical care is important in global health initiatives. In particular, neurosurgical care is as limited as 1-to-10 million people in parts of the world. We performed a systematic literature review to examine the worldwide incidence of central nervous system vascular lesions (CNS-VL) and a meta-analysis of aneurysmal subarachnoid hemorrhage (ASAH) in order to define the disease burden and inform neurosurgical global health efforts...

Vascular malformations are classified primarily according to their flow characteristics, slow flow (lymphatic and venous) or fast flow (arteriovenous). They can occur anywhere in the body but have a unique presentation when affecting the female pelvis. With a detailed clinical history and the proper imaging studies, the correct diagnosis can be made and the best treatment can be initiated. Lymphatic and venous malformations are often treated with sclerotherapy while arteriovenous malformations usually require embolization...

Paradoxical embolism due to isolated pulmonary arteriovenous malformation (AVM) is an uncommon cause of ischemic stroke, with the majority occurring in patients who have not yet been diagnosed with their malformation. We report a 32-year-old man who presented with an abrupt onset of right facial weakness and expressive aphasia. Brain magnetic resonance imaging revealed an acute infarct in the left middle cerebral artery territory and chronic infarcts in the bilateral cerebellar hemispheres. A cardioembolic mechanism was initially considered in the setting of perimyocarditis diagnosed a few months earlier...

BACKGROUND: Brain arteriovenous malformation (BAVM) is a congenital cerebral vascular disease that characterized with intracranial hemorrhage and epilepsy. It has some risk in current treatments including microsurgery, endovascular, and radiation therapy. Some patients with bAVMs may keep unruptured in their whole life. Whether it should be treated depends on the evaluation of the hemorrhage risk of bAVM. Although previous studies gave many significant predictors, we tried to find some new and more significant predictors in 173 patients with bAVMS by retrospective analysis...

Alveolar soft part sarcoma (ASPS) is a rare form of soft-tissue sarcoma arising from connective tissue. It is most often seen in adolescents and young adults and has high propensity for recurrence and metastasis. Clinically, it mimics haemangioma or arteriovenous malformations. In our case report, an 18-year-old female presented with markedly vascular tumour in the left forearm, for which excision biopsy was done. Histopathological report revealed ASPS. The patient was screened for metastasis. Ultrasound abdomen, computed tomography (CT) chest, CT brain and whole-body skeletal survey was done...

INTRODUCTION: Arteriovenous malformations (AVMs) are a type of vascular malformation characterised by an abnormal connection between arteries and veins, bypassing the capillary system. This absence of capillaries generates an elevated pressure (hyperdebit), in both the AVM and the venous drainage, increasing the risk of rupture. Management modalities are: observation, microsurgical clipping, endovascular treatment and radiosurgery. The former can be used alone or in the frame of a multidisciplinary approach...

INTRODUCTION: High-flow arteriovenous malformations (HF-AVMs) are congenital vascular malformations. Typical localizations include the face, oral cavity, and extremities. Due to the high recurrence rate of AVM after incomplete resection or embolization, a combination of both therapeutic modalities has become the preferred choice of treatment. Therefore, we have developed an interdisciplinary therapeutic treatment algorithm for facial HF-AVM and performed a systematic review of the literature...
