P. Mahr et al., EXTRAMURAL VESSEL WALL HEMATOMA CAUSING A REDUCED VESSEL DIAMETER AFTER CORONARY STENTING - DIAGNOSIS BY INTRAVASCULAR ULTRASOUND AND TREATMENT BY STENT IMPLANTATION, Catheterization and cardiovascular diagnosis, 43(4), 1998, pp. 438-443
An extramural vessel wall hematoma occured immediately after implantin
g a coronary stent in an in-stent-restenosis of the intermedius branch
. Angiography showed a significant luminal reduction distal to the int
ervention site, Intravascular ultrasound revealed an extramural echolu
cent zone compressing the vessel lumen. Stent implantation compressed
the hematoma and allowed adequate myocardial perfusion. This demonstra
tes the value of intravascular ultrasound (IVUS) in cases of unusual a
ngiographic results which can help to manage complications after coron
ary intervention. (C) 1998 Wiley-Liss, Inc.
