We report an unusual etiology for a thromboembolic complication. Occlusion of the middle cerebral artery occurred before embolization of an intracranial aneurysm. Attempts to recanalize the artery failed by using both fibrinolytics and IIb/IIIa inhibitors but succeeded with mechanical thrombectomy with a micro-snare. Pathologic analysis of the thrombus(More)
The aims of this study were, firstly, to monitor temperature with magnetic resonance (MR) during laser ablations performed in pig livers in vivo in a low-field open scanner (0.23T) and, secondly, to study the feasibility of lesion size prediction. Spin-echo (SE) images of 29 sec acquired during laser applications allowed calculation of temperature maps(More)
A new approach for the management of frozen shoulder associated with reflex sympathetic dystrophy is presented. A suprascapular nerve block was performed by needle insertion behind the lateral end of the clavicle at its junction with the insertion of the trapezius muscle; the needle was directed downwards and backwards. The suprascapular nerve was(More)
PURPOSE To develop a precisely calibrated, perfectly spherical, stainable, soft, and implantable but nonresorbable particulate embolization material. METHODS Calibrated particles with a trisacryl gelatin polymer core and hydrophilic surface characteristics were obtained by reversed emulsion synthesis followed by application of a wet-sieving technique.(More)
PURPOSE To evaluate an embolic agent that is precisely calibrated, perfectly spherical in shape, and soft but nonresorbable for use in the embolization of vascular disease of the head, neck, and spine in humans. METHODS We used supple, hydrophilic, and calibrated trisacryl gelatin microspheres 200, 400, 600, 800 and 1000 microns in diameter for(More)
PURPOSE The transversus abdominis plane (TAP) block is a technique increasingly used for analgesia after surgery on the anterior abdominal wall. We undertook this study to determine the feasibility and analgesic efficacy of ultrasound-guided TAP blocks in morbidly obese patients. We describe the dermatomal spread of local anesthetic in TAP blocks(More)
Malignant highly vascularized tumors such as hemangiopericytomas (HPC) may mimic a benign arteriovenous malformation (AVM) which is sometimes still referred to as "angioma". We describe the clinical and radiological findings of a facial hemangiopericytoma in comparison to an AVM in order to avoid misdiagnosis between these two pathologies since evolution(More)
The diagnosis of acute Guillain-Barré syndrome and chronic inflammatory demyelinating polyradiculoneuropathy is based on clinical characteristics, abnormalities on nerve conduction studies, and nerve biopsy specimens indicating demyelination. Inflammation and edema are also common findings in nerve specimens. Immunotherapy is helpful in these dysimmune(More)
