The bifurcation of the common femoral artery (CFA) into superficial and profunda femoris arteries (PFA) and the branching pattern of the PFA are subject to considerable normal anatomical variation. These variation patterns were assessed on normal lower limb angiograms of 94 adult patients. The main pattern (in 81% of patients) consisted of both medial and(More)
Methods are now available which are sensitive enough to detect digoxin concentration to levels of 5 mug./ml. Hitherto the degree of sensitivity of specific chemical methods was not acceptable for clinical application. Digoxin-specific antibodies have recently been prepared (Butler and Chen, 1967), and a test based on the radioimmunoassay principle has now(More)
Treatment with heparin or streptokinase was allocated randomly to 30 patients with life-threatening pulmonary embolism verified by angiography. Treatment was given for 72 hours and pulmonary angiography was repeated. There was significantly greater (P < 0.001) evidence of thrombolysis in those patients treated with streptokinase compared with those treated(More)
The amount of diagnostic radiation received by neonates at a large maternity hospital in 1982 was calculated. The risk of inducing neoplasia is unlikely to be greater than one in 280,000 for each radiograph of chest or abdomen. Provided that the exposure of the newborn to radiation at the John Radcliffe Hospital is typical of the rest of the country, and(More)
The primary objective of this study was to compare the antihypertensive efficacy and safety of intravenously administered nicardipine with that of intravenous nitroprusside (SNP) in patients with severe hypertension. The study was conducted in 121 patients with severe hypertension (diastolic blood pressure [BP] > 120 mm Hg, or systolic BP > 200 mm Hg).(More)
Clinical methods and directional Doppler velocimetry applied to superficial veins have been used to study 527 patients with venous disorders in the lower limbs. Phlebography assisted by the image intensifier has been carried out in 80 of these patients. All examinations have been done with the patient upright, exercising, and without use of any artefact,(More)
A placebo-controlled, double-blind multicenter trial was conducted in 123 patients with severe hypertension to examine the efficacy and safety of intravenously administered nicardipine hydrochloride in controlling blood pressure. Seventy-three patients were initially randomized to receive nicardipine treatment. This group had an initial blood pressure of(More)
