From two different specimens of a chronic prosthetic hip infection taken at an interval of 2 months a slow-growing gram-negative bacterium was isolated in pure culture. The strain grew with the typical features of a small-colony variant (SCV). 16S rRNA sequencing identified the bacterium as Escherichia coli. Biochemical characterization demonstrated(More)
BACKGROUND Uremic small-artery disease with medial calcification and intimal hyperplasia can lead to life-threatening skin necrosis or acral gangrene. It is a distinct complication of chronic renal failure that must be differentiated from soft-tissue calcification. An increased calcium-phosphate product and secondary hyperparathyroidism are the main(More)
This report is an analysis of 252 popliteal artery aneurysms (PAA) in 167 patients treated surgically at the University Hospital in Zurich during a 27 year period from 1965 to 1991. The predominance of male patients (95 percent) was consistent with that of other reports. PAA were bilateral in 51 percent of the patients and were associated with aneurysms at(More)
In the management of leg ulcers two aspects should be considered, i.e. the exact underlying condition (main cause and contributing factors) and local conditions. Concomitant peripheral arterial occlusive disease must systematically be excluded. Effective compression therapy (35 mmHg pressure at the distal calf) is the corner-stone in treatment of venous leg(More)
From 1967 to 1992 at the University Hospital of Zurich 16 patients (14 male, 2 female) with 22 popliteal artery entrapment syndromes underwent a surgical treatment. In this period several different operation procedures were used. The modern operative procedure depends on the degree of the arteries wall compression. The procedure of choice for minimal(More)
Four patients with hereditary lymphedema present at birth (Milroy's disease) have been studied by fluorescence microlymphography (1, 7). The videomicroscopy technique failed to visualize any lymphatic capillary in the edematous part of their legs. In sporadic primary lymphedema with late manifestation, however, a well developed superficial capillary network(More)
Ligation of the internal iliac artery mostly remains without consequences because of the well established collateral network. In patients with compromised collateral circulation however, acute interruption of both hypogastric arteries during aorto-iliac surgery or transluminal embolisation can lead to necrosis of the gluteal muscles and other adjacent(More)
Rupture of a popliteal artery aneurysm is an unusual complication and did occur six times in our series of 252 popliteal artery aneurysms that underwent operative repair from January 1965 to December 1991. Rupture while equally serious as thrombosis of the popliteal artery aneurysm of distal embolization from the aneurysm, is reported as an exceedingly(More)
