Osteoid osteoma of the foot can be difficult to diagnose, clinical presentation may mimicking other local pathologies leading a considerable delay in diagnosis. We report an exceptional localization osteoid second metatarsal 30-year-old patient, expressed for 3 years by metatarsalgia, with no and radiological architecture defect foot. After discovering nidus, patient underwent surgical excision...

AIM This study explored the value of using a vessel fusion technique for visualizing and evaluating the vessel structure of patients diagnosed with arteriovenous malformations (AVMs). MATERIALS AND methods 10 patients with AVMs supplied by multiple cerebral arteries were investigated. The three-dimensional structure of the AVM nidus, feeding arteries, and draining veins were reconstructed fro...

The use of non-absorbable suture materials for cystic duct ligation after cholecystectomy can expose patients to the risk of recurrent stone formation in the common bile duct (CBD). However, in Korea suture materials have rarely been found to act as a nidus for common bile duct calculus formation. Recently, we experienced a case in which suture material, that had migrated from a previous cholec...

We assessed the suitability of a swine experimental arteriovenous malformation model for laboratory simulations and training in endovascular embolotherapy. Embolizations with liquid glue or particles were performed in 10 animals. The parameters of injection (microcatheter position, concentration and volume of embolic agent, injection rate) were deliberately varied to simulate results that may b...

Two patients with dural arteriovenous fistulas (DAVFs) and unsuccessful transarterial embolizations were treated with a technique for selective transvenous embolization. A 5F catheter was advanced from a femoral vein access into the internal jugular bulb and a catheter was navigated through the sinus lumen into the involved cortical veins or the parasinusal venous draining channels of the DAVFs...

Intracranial arteriovenous malformation (AVM) is a rare cause of trigeminal neuralgia (TGN). In this presented case, successful resolution of AVM-related TGN following embolization and gamma knife stereotactic radiosurgery (GKRS) was obtained. A patient suffered from TGN on the left side, which was thought to be caused by root entry zone compression by dilated superior cerebellar artery (SCA) a...

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 ...

rare vascular lesions of the brain. These lesions differ from arteriovenous malformation (AVMs) as they are direct artery to vein connections, have no nidus, and are composed of one or more direct arterial feeders with a single draining vein. Many of these have associated venous varix or giant venous aneurysms (1). Owing to the absence of a nidus, closure of the shunt by either endovascular or ...

Several cases of recurrent stone formation caused by a surgical material as a nidus have been reported. Recently, we experienced one case in which a migrated metal stent might have been served as a nidus for common duct stone formation. The diagnosis was confirmed by ERCP, the stone was successfully removed with endoscopic therapy. Six years ago, she had undergone a lithotripsy using a percutan...

= Abstract = The authors report a case of recurrent arteriovenous malformation (AVM), which has been completely removed and disappeared on postoperative angiography four years ago. Initially, a t the age of nine years, she presented intracerebral hematoma. The angiography demonstrated an aneurysm and AVM nidus located in the posterior frontal area, fed by the branches of the anterior and middle...
