[Percutaneous puncture of the femoral vein for haemodialysis: report of 5000 punctures (author's transl)]. / Die perkutane Punktion der Vena femoralis zur Hämodialysebehandlung. Erfahrungen und Komplikationen bei 5000 Punktionen.

Using the Seldinger technique, a total of 5306 percutaneous femoral vein catheterisations were performed in the course of ten years. Two-catheter venovenous dialysis was performed 2357 times and single-needle technique 592 times. There were five important complications: severe retroperitoneal bleeding after perforation of the external iliac vein three times, fatal bleeding from the femoral artery once, and reversible damage to the femoral nerve once. The results indicate that for every 1000 percutaneous femoral-vein catheterisations one must expect one severe complication. However, by using the correct catheter technique, especially careful manipulation of the wire, complications can be largely avoided.

[Primary malignant nephrosclerosis (author's transl)]. / Primäre maligne Nephrosklerose

Primary malignant nephrosclerosis shows a haemolytic-uraemic symptomatology and can be differentiated from secondary malignant nephrosclerosis on clinical and histological grounds. The disease was observed in 4 patients: a 25-year-old man and 3 women aged 19, 28 and 49 years. The disease is characterized by a fulminating course, malignant hypertension with progressive retinopathy, and development of progressive renal failure with subsequent irreversible anuria. In addition haemolytic anaemia or posthaemolytic states as well as consumption coagulopathy occur. In 2 cases schizozytes and in particular helmet-shaped forms could be demonstrated. On histology an obliterating necrotizing vascular change is seen which is limited to the kidneys as was demonstrated in one case by angiography. Therapeutic attempts included antibiotics, steroids, heparin, streptokinase, antihypertensive drugs, and haemodialysis. The 3 female patients died, the man survived after bilateral nephrectomy.
