The extracardiac conduit Fontan procedure is the last surgical step in the treatment of patients with a functional single ventricle. An acquired pulmonary arteriovenous malformation may appear perioperatively or postoperatively due to an uneven hepatic flow distribution. Here we report a case of a bifurcated Y-graft Fontan operation in a 15-year-old male patient with a unilateral pulmonary arte...

we report an unusual case of hemimegalencephaly (hmg) associated with ipsilateral congenital-infiltrating lipomatosis of the face in a five-month-old boy. hemimegalencephaly is a rare but unique malformation characterized by enlargement of all or parts of a cerebral hemisphere. the affected hemisphere may have focal or diffuse neuronal migration defects, with areas of polymicrogyria, pachygyria...

Intravascular occlusion by various catheterization techniques was used to treat 27 cases of carotid-cavernous fistula, giant intracavernous aneurysm, and cerebral or dural arteriovenous malformation. Several case reports are presented. The detachable balloon technique proved valuable in the treatment of traumatic carotid-cavernous fistula and giant aneurysm. Calibrated-leak balloon catheterizat...

Brain ArterioVenous Malformation (BAVM) is an abnormal tangle of brain blood vessels where arteries shunt directly into veins with no intervening capillary bed which causes high pressure and hemorrhage risk. The success of treatment by embolization in interventional neuroradiology is highly dependent on the accuracy of the vessels visualization. In this paper the performance of clustering techn...

We assessed the feasibility of creating an experimental arteriovenous malformation model in swine by diverting and increasing blood flow through bilateral retia mirabilia. This was achieved by surgical formation of a large right-sided carotid-jugular fistula, in combination with endovascular occlusion of several neck arteries ipsilateral to the fistula. Using this technique, 11 of 13 swine demo...

A 9-year-old girl with a several-month history of unilateral intermittent headaches presented to the hospital with worsening headaches and unsteadiness. Neurologic exam was positive for a mild right hemiparesis and right homonymous hemianopsia. Noncontrast computed tomography revealed an engorged sagittal and straight sinus with prominent cortical veins concerning an arteriovenous malformation ...

A 55-year-old woman underwent radiosurgery for a left cerebral hemisphere arteriovenous malformation (AVM) and developed radiation-induced necrosis causing a massive edema in the surrounding brain tissues. Despite various therapies, the edema expanded to the ipsilateral hemisphere and induced neurological symptoms. The radiation-induced necrotic lesion was surgically removed 4 years after radio...

During a 3 year period, 21 patients with spinal cord vascular malformations involving the anterior spinal artery were treated by embolization through this artery. Of four cases of extramedullary arteriovenous fistula, two patients embolized at an early stage showed excellent results, whereas results were mediocre in two patients who were paraplegic at embolization. Of 17 cases of intramedullary...

The occurrence of a primary brain tumour in association with a cerebral arteriovenous malformation (AVM) is a recognized but rarely reported finding. A 56-year-old female presented following a single tonic clonic seizure. Radiological investigations revealed a left posterior frontal parafalcine meningioma and a left parietal AVM. Both were uneventfully resected. Whether there is a causal relati...

Pulsatile tinnitus is a rarely occurring symptom of vascular origin. Most frequently, the symptoms are due to an arteriovenous malformation, to a tumor of the jugular glomus or to a local arterial stenosis. A 39-yr-old Korean male suffering from pulsatile tinnitus of the left ear was diagnosed to have dural arteriovenous malformation of the jugular bulb. Magnetic resonance imaging and angiograp...
