Light and electron microscopic study of pathomorphological changes on the arterial wall after transluminal angioplasty.

The vascular complications arising after the percutaneous transluminal angioplasty (PTA) of the arteriosclerotic stenosis in the right superficial femoral artery of a 70-year old female patient six days prior to her death were studied by means of light microscopy and with the transmission and scanning electron microscopes. The pictures revealed disruption in the vascular wall of the superficial femoral artery, fresh thrombus in the dissecting aneurysm of arteriosclerotic origin in the distal part of the posterior tibial artery and haemorrhage in the media. A connection is suggested between these findings and the angioplastic intervention.

Ultrastructural investigations of finger pulp biopsies: a study of 31 patients with Raynaud's syndrome.

Finger pulp biopsies of 31 patients suffering from Raynaud's syndrome (RS) were investigated by light and electron microscopy. The patients suffered from various underlying diseases. Interest was focused on the vascular changes and nerve and connective tissue alterations, especially the elastic fiber changes.

Scleroderma-heart and conduction disturbances.

Disturbances of impulse formation and conduction may arise in the early stage of scleroderma, as a sign of cardiac involvement, termed "scleroderma heart". The incidence of various intraventricular conduction disturbances and their association with other disorders of cardiac rhythm were analysed in 193 scleroderma-patients by age. The presence of ventricular conduction abnormalities was found to carry an increased hazard of the production of disorders of atrioventricular conduction and of abnormal impulse formation.
