Aim: Role of Doppler ultrasound in comparison with MDCT angiography the assessment lower limb Peripheral arterial disease. Methodology: This study was conducted Radiology department Shalamar Hospital Lahore. A total 42 patients (31 males and 11 females) diagnosed PAD by using both MDCTA were included. The data collected entered, tabulated statistically analyzed on IBM-SPSS 25.0 version. Results...

1. In 13 patients with hypertension and renal artery stenosis the stenosis was dilated by an intra-arterial balloon catheter under local anaesthesia. 2. In all but one instance arteriography after the dilatation showed considerable widening of the stenosed area. 3. Six patients had a temporary increase of serum creatinine that lasted only a few days. 4. In seven patients, who had a prolonged tr...

cerebral hemodynamics (1). Neurological symptoms associated with carotid stenosis are mainly produced by thromboembolic stroke. They can be also attributed to altered cerebral hemodynamics (2). Hemodynamic factors have long been associated with the symptomatic status of stenosis, although their role is controversial (1). A percentage of patients have an insufficient collateral supply and so art...

A computerized method for measuring relative coronary arterial stenosis by cinevideodensitometric analysis of 35 mm coronary arteriograms was developed and validated. Video images of projected coronary arteriographic frames were digitized into a 512 X 512 matrix (256 gray levels) by computer analysis that compared integrated contrast density measured over stenotic and normal arterial segments a...

Doppler ultrasound is a noninvasive technique which is widely used in medicine for the assessment of blood flow in vessels. Therefore, Doppler ultrasonography is known as a reliable technique, which demonstrates the flow characteristics and resistance of internal carotid arteries in stenosis and occlusion conditions. In this study, internal carotid arterial Doppler signals recorded from 130 sub...

OBJECTIVE To study the stenosis of the carotid arteries in patients with symptomatic peripheral arterial disease. METHODS we assessed 100 consecutive patients with symptomatic peripheral arterial disease in stages of intermittent claudication, rest pain or ulceration. Carotid stenosis was studied by echo-color-doppler, and considered significant when greater than or equal to 50%. We used univ...

In recipients of rotary blood pumps for cardiac assist, the pulsatility of arterial flow is considerably diminished. This influences the shear stress patterns and streamlines in the arterial bed, with potential influence on washout and plaque growth. These effects may be aggravated in the recirculation area of stenoses, and therefore, exclude patients with atherosclerosis from the therapy with ...

OBJECTIVES To evaluate peripheral arterial occlusive disease in HIV-infected patients regarding clinical presentation and outcome of surgical intervention. DESIGN Prospective clinical survey. PATIENTS AND METHODS Routine voluntary testing for HIV/AIDS was performed in all patients presenting to our vascular unit. HIV+ patients were enrolled in a registry and followed up prospectively. RES...

introduction pulmonary vein stenosis includes narrowing of one or more pulmonary veins that may have congenital or acquired causes. congenital pulmonary vein stenosis is a rare condition and also a rare cause for pulmonary hypertension. since identifying the etiology of pulmonary hypertension plays a crucial role in medical and surgical planning, we decided to introduce a rare case of pulmonary...
