title: [False aneurysm of the wall of a venous graft in a patient with an implanted MGuard type of coronary stent: case report and description of the microscopic changes].
abstract: The present case report demonstrates a development of a false aneurysm in a venous coronary bypass graft wall, which developed at the previous MGuard stent implantation area in a 67-year-old patient. Subsequent histological examination revealed a false aneurysm image, without detection of vascular wall layers in its wall. Microscopically mild neointimal proliferation within the stent was also detected, with a strong granulomatous inflammatory reaction, mostly focused on the PET fibre mesh present on the surface of the stent. This article demonstrates the need for a multidisciplinary approach in dealing with pathological changes in stented blood vessels; the authors would also like to remind the public of the possibility of histological examination of stented vessels in the Czech Republic.
