The efficacy of forceful ankle and toe exercises to increase venous return: A comprehensive Doppler ultrasound study.

Objective Venous stasis is a risk factor for venous thromboembolism. We aimed to determine the efficacy of forceful foot exercises for actuation of the calf muscle pump to counteract stasis. Methods We examined 20 seated healthy subjects.

Evaluation of the deep venous system in patients with suspected pulmonary embolism with multi-detector CT: a prospective study in comparison to Doppler sonography.

Objective: This prospective study was done to evaluate the ability of indirect multidetector row CT venography (CTV) in detecting deep venous thrombosis of the pelvis and the thighs in comparison with Doppler sonography in patients with suspected pulmonary embolism (PE).

Methods: Forty-one patients with suspected PE were included, and CTV (collimation 4 x 2.5 mm, table feed 12.
