Impedance Phlebography
Impedance phlebography, a noninvasive approach to the diagnosis of venous thrombosis, depends on decreasing calf electrical impedance in normal subjects during inspiration. In order to assess the relationship between impedance changes and inspiratory volume, normal subjects were studied at various depths of inspiration. The mean inspiration volume required for a result indicating no evidence of...
متن کاملDevelopment of a real-time, semi-capacitive impedance phlebography device
Chronic venous insufficiency of the lower limbs is a disease which is caused by an increased blood pressure inside the veins of the leg and the resulting increase of the contained blood volume. This work focuses on developing a device which uses impedance plethysmography, also known as impedance phlebography, to obtain information about the blood volume in the lower leg and provides the possibi...
متن کاملInadvertent cardiac phlebography
We are reporting a case of a 80-year-old lady with effort angina who underwent coronary angiography through the right radial artery, using a dedicated radial multipurpose 5 French Optitorque Tiger catheter. The catheter was advanced into the left ventricle and a left ventriculogram was obtained, while the catheter appeared optimally placed at the centre of the ventricle and the pressure wavefor...
متن کاملComplications of ascending phlebography of the leg.
Forty patients were studied prospectively for complications of ascending phlebography. The commonest immediate complication was pain at the site of injection and the commonest delayed complication pain in the foot or calf. Out of 30 patients with pain in the foot and calf, 15 had venous thrombosis. Review of 200 case notes disclosed only one recorded complication--namely, necrosis of the dorsal...
متن کاملComputed orbital phlebography of the cavernous sinuses.
Computed orbital phlebography (COP), described as computed tomography with concomitant injection of contrast medium into a frontal vein, was used to evaluate the cavernous sinuses in 19 patients with intrasellar or parasellar lesions and in two normal controls. Bilateral opacification occurred in 12 subjects, eight of whom had pituitary tumors. Unilateral partial obliteration was encountered in...
