ABSTRACT
VasoSeal is a purified bovine, absorbable collagen plug currently successfully used to close the femoral arterial puncture site after cardiac catheterization under full anticoagulation. Up to now there has been no experience with potential complications. We observed acute ischemia in the right lower leg of 2/100 patients 36 resp. 24 h after successful closure of the puncture site with VasoSeal. Angiography confirmed acute occlusion of the distal A. poplitea dextra. A 25-mm resp. 50-mm long cylindrical foreign body embolus was removed with a Fogarty-catheter by retrograde indirect embolectomy. Histopathology confirmed a fresh collagen clot with appositional thrombosis.

This paper presents a comparison of the diagnostic value of CT studies and conventional radiological diagnosis, based on 46 CT studies, in patients with inflammatory bone lesions of the spine (n = 20) before and after surgical interventions (n = 12). In cases with a tentative clinical diagnosis of an inflammatory bone lesion, CT will not supplant conventional radiological diagnosis as the roentgenologic method of first choice. The superiority of CT is based on its ability to demonstrate intraspinal, paravertebral, and intervertebral complications. Osseous incorporation of spongiosa parts and the healing of paravertebral and intraspinal complications can be assessed more easily and accurately with CT.

The authors present the results of a performance comparison between CT and conventional x-ray film diagnosis (plain film and tomography) in 93 patients with benign, semimalignant and malignant bone tumours, basing on 124 CT examinations with 176 tumorous bone lesions of the vertebral column. The type, size and incidence rate of the superiority of CT in imaging tumorous bone lesions and its morphologic characterisation, are described.
