ABSTRACT
Embolisation of head and neck hypervascular tumours and arterioveinous malformations [AVMs] is now a well-established therapeutic procedure. The purpose of this study was to analyse the technique and to evaluate the safety and value of preoperative embolization of hypervascular lesions. We retrospectively reviewed the records of 5 patients, aged between 14 and 47 years, with hypervascular tumours and AVMs in the head and neck. Lesions were distributed as follow: nasal angiofibroma [n=1], nasal angioleiomyoma [n=1], nasopharyngeal angiofibroma [n=1], aneurysmal bone cyst in the posterior element of the second cervical vertebra [n=1] and AVM of the inferior lip [n=1]. Angiography and embolization were carried out at the same time. Complete exclusion of lesions was obtained without any complications. Complementary surgical resection was performed with not notable blood loss

MRI semeiology of hepatic tumors was assessed with a retrospective study of 132 patients explored between May 1998 and December 2001. MR examinations were acquired with a one Tesla operating system. All images were acquired by a T2-weighted fast spin echo MR and dynamic flash MR with Gadolinium. Hemangiomas demonstrate characteristic signs in most cases, as was described in the literature. However, adenoma, hepatocellular carcinoma and metastases have various and less specific features

Two patients with gynaecological hemorrhage underwent successfully trans-arterial embolization. The first woman had an uncontrollable perineal hemorrhage following a delivery with forceps. Angiography showed extravasation of contrast from right and left vaginal artery. Hyperselective embolisation stopped the vaginal bleeding. The second woman had massive hemorrhage following radiotherapy for cervical cancer. Angiography demonstrated extravasation of contrast from both uterine arteries. The bleeding was controlled after hyperselective embolisation. Emergency arterial embolisation is a safe and effective means of control of irrepressible genital hemorrhage
