ABSTRACT
A case report of a patient with unusual compressive syndrome is reported herein. A 27-year-old woman was referred to our hospital due to intermittent claudication in the left thigh and calf which gradually developed over the last five months. Angiography showed an atypical short occlusion of the external iliac artery. Only surgical revision made an exact diagnosis. The formation compressing the artery was a ganglion that originated from the hip joint and adhered to the artery. Resection of the ganglion was carried out. The adjacent segment of the artery was removed and replaced by end-to-end venous graft using vena saphena magna. From the operation until present (30 months) the patient remains symptom-free. To our knowledge a hip joint ganglion compressing the artery and causing symptoms of peripheral arterial disease has not been previously reported in medical literature.

The author describes three variants of the surface treatment of PMMA using a special method suggested by Wichterle. Modified surfaces of PMMA discs in three variations A, B, C were followed in subcutaneous implantation in rats during three months and were well tolerated. The final stage was characterized by a stabilized fibrous capsule. The relationship between modified PMMA, glass and pure PMMA in vitro using human and animal blood was also investigated. The author analyzes experiments carried out with human blood (Lee-White's time of blood clotting and fibrin formation after Bürker) and proves better antithrombogenic properties of modified PMMA to control on glass and pure PMMA.

Blood chambers of counterpulsation heart pumps were subjected to a special hydrophilization process in order to reduce the coagulation activity of the surface of poly(methyl methacrylate) (PMMA). The chemical treatment of the surface was carried out in three variants, namely A (ethylenglycol), B (diethylenglycol), C (glycerine) by using concentrated sulphuric acid with subsequent neutralization [12]. Controls were performed with the same pumps made of PMMA but without surface treatment. 30 dogs were used in the experiments.
