Prospective radiological study concerning a series of patients suffering from conductive or mixed hearing loss due to superior semicircular canal dehiscence.

The aim of this study is to appreciate the incidence of patients with isolated conductive hearing loss with normal drum due to superior semicircular canal dehiscence (SCD). It is a prospective radiological study. Two hundred and seventy-two patients with a normal drum suffering from isolated unilateral or bilateral conductive or mixed hearing loss were included in a prospective radiological study.

Pathology of the ossicular chain: comparison between virtual endoscopy and 2D spiral CT-data.

Objective: The purpose of this study was to assess the value of virtual endoscopy (VE) in the diagnosis of lesions of the ossicular chain and to compare virtual endoscopy and two-dimensional (2D) spiral computed tomography (CT) data.

Study Design: Retrospective study.

Setting: A university hospital.

Concordance rate differences of 3 noninvasive imaging techniques to measure carotid stenosis in clinical routine practice: results of the CARMEDAS multicenter study.

Background And Purpose: To replace digital subtraction angiography (DSA) in carotid stenosis evaluation, noninvasive imaging techniques have to reach a high concordance rate. Our purpose is to compare the concordance rates of contrast-enhanced MR angiography (CEMRA) and CT angiography (CTA) with Doppler ultrasound (DUS) in clinical routine practice.

Methods: We evaluated prospectively with DUS, CEMRA, and CTA 150 patients suspected of carotid stenosis.

Contrast medium-induced acute renal failure and cholesterol embolism after radiological procedures: incidence, risk factors, and compliance with recommendations.

BACKGROUND: After radiological procedures, the incidence of acute renal failure varies greatly, and cholesterol embolism may not always be recognized. Little, if anything, is known about whether recommendations for the prevention of either complication are correctly implemented. METHODS: We performed a prospective epidemiological study in a large population (n=809) of consecutive inpatients in a university hospital.

Place of embolization of the uterine arteries in the management of post-partum haemorrhage: a study of 12 cases.

Objective: To assess the current place of embolization of the uterine arteries in the treatment of severe post-partum haemorrhages.

Materials And Methods: A retrospective study of 13,160 deliveries in a level III maternity unit between January 1996 and December 2001. Five hundred and forty-nine post-partum haemorrhages were diagnosed.
