Intraosseous arteriovenous malformation (AVM) in the craniofacial region is rare. When it occurs, it is predominantly located in the mandible and maxilla. We encountered a 43-year-old woman with Klippel-Trenaunay syndrome affecting the right lower extremity who presented with a left orbital chemosis and proptosis mimicking the cavernous sinus dural arteriovenous fistula. Computed tomography ang...

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by the triad of epistaxis, telangiectasia and vascular malformations. Pulmonary vascular complications associated with this disease include pulmonary arteriovenous malformations (AVM) and, less frequently, pulmonary hypertension (PH). We report the case of a patient who presented multiple pulmonary AVM a...

Pelvic arteriovenous malformation (AVM) is a rare condition mostly requiring a complex therapeutic strategy. The surgical approach is challenging and burdened by relatively high mortality and morbidity rates. No guidelines are available for the endovascular treatment of AVM because the literature is limited to small case series and case reports. We present a complex case of a pelvic AVM associa...

Trigeminal neuralgia (TGN) is rarely caused by arteriovenous malformation (AVM). The AVMs causing TGN are reported mostly in the ipsilateral posterior fossa. The culprit vessels are dilated feeding artery or nidus itself. We present a rare case of TGN caused by dilated draining veins from a supratentorial AVM. The patient suffered from TGN with an incidentally found large AVM, which had been le...

Regardless hemifacial spasm (HFS) or trigeminal neuralgia (TN) is commonly caused by an offending artery, 36 cases caused by an arteriovenous malformation (AVM) have been reported in the literature. However, the concurrent HFS and TN caused by AVM have never been reported so far. We reported a case of coexistent HFS-TN associated with a huge AVM, and the symptoms of both spasm and pain relieved...

A 47-year-old patient presented from outside the hospital for evaluation of iron deficiency anemia (IDA). The endoscopic workup suggested a gastric antral subepithelial lesion with an overlying arteriovenous malformation (AVM). Endoscopic ultrasound (EUS) revealed the lesion to be a lipoma. Given the patient's anemia and blood transfusion requirements, the AVM was treated with argon plasma coag...

Uterine arteriovenous malformation (AVM) is a rare condition, with fewer than 100 cases reported in the literature. Despite it being rare, it is a potentially life-threatening condition. This case report describes a 33-year-old woman who presented with secondary post-partum hemorrhage. Transabdominal ultrasound (US) of the pelvis showed increased vascularity with multidirectional flow of the ut...

A scrotal arteriovenous malformation (AVM) is a rare condition representing an abnormal connection between the arterial and venous systems of vessels supplying the scrotum. Scrotal AVMs are usually treated via transcatheter embolization, surgical extirpation, or a combination of the two approaches. A 41-year-old man developed a life-threatening hemorrhage from a scrotal AVM. After hemodynamic s...

Discussion Our patient has a vascular lesion of the brain which looks like an AVM though the images do not clearly demonstrate the nidus of the AVM. Th e ‘snake’ is actually the large draining vein and not the AVM nidus. Giant AVMs are diffi cult to treat and oft en carry higher treatment morbidity and mortality rates than do smaller ones. Patients Dear Sir, A 45-year-old male presented to our ...

background and objective: cerebral arteriovenous malformation (cavm) hemodynamic is disease condition, results changes in the flow and pressure level in cerebral blood vessels. measuring flow and pressure without catheter intervention along the vessel is big challenge due to vessel bifurcations/complex bifurcations in arteriovenous malformation patients. the vessel geometry in cavm patients are...
