Magnetic resonance angiography in infrapopliteal arterial disease: prospective comparison of 1.5 and 3 Tesla magnetic resonance imaging.

Purpose: To prospectively determine the accuracy of 1.5 Tesla (T) and 3 T magnetic resonance angiography (MRA) versus digital subtraction angiography (DSA) in the depiction of infrageniculate arteries in patients with symptomatic peripheral arterial disease.

Patients And Methods: A prospective 1.

Influence of secondary infection on amputation in chronic critical limb ischemia.

Objectives: To evaluate the influence of secondary infection on major amputation in chronic critical leg ischemia (CLI).

Design: Prospective, controlled observational study.

Materials And Methods: Sixty-seven patients with CLI and ischemic lesions participated in the study.

Effect of silver-threads-containing compression stockings on the cutaneous microcirculation: a double-blind, randomized cross-over study.

Recently silver fiber-containing compression stockings for the use in patients with chronic venous insufficiency (CVI) were introduced to the market. In order to gain some first insight into the effects of these new fabrics on the cutaneous microcirculation, a double-blind, randomized cross-over trial was performed in 10 healthy volunteers. A 3 days run-in phase preceded the (2 x10 days) treatment phases and was used to assess the reproducibility of the primary endpoint, which was the transcutaneous partial oxygen pressure (tcpO(2)) measured at a probe temperature of 44 degrees C in the perimalleolar region of the reference leg in supine and dependent leg positions.

Mixed monosodium urate and calcium pyrophosphate crystal-induced arthropathy. A review of seventeen cases.

Among 4620 synovial fluid specimens examined in our laboratory from 1989 through 1992, 18.3% contained crystals (calcium pyrophosphate dihydrate, 55.7%; monosodium urate, 42%).
