Venous Occlusion Test

Rationale of venous occlusion plethysmography.

The experimental evidence reported here supports the validity of venous occlusion plethysmog-raphy. 1 modified the technic of Brodie, 2 venous occlusion plethysmography has been widely employed to estimate blood flow in fingers, toes, and limbs. Several excellent comprehensive reviews of the technical pitfalls of the method are available. 3-4 The validity of the venous occlusion technic of plet...

Venous phase timing during balloon test occlusion as a criterion for permanent internal carotid artery sacrifice.

PURPOSE The purpose of this study was to evaluate the reliability of angiography-based balloon test occlusion (BTO) criteria to decide whether to perform internal carotid artery (ICA) permanent occlusion. METHODS From March 1999 to August 2004, 60 patients underwent therapeutic ICA occlusion. Angiographic BTO was performed systematically in all patients under general anesthesia (GA). No clini...

Thrombolytic therapy for central venous catheter occlusion.

BACKGROUND Long-term central venous catheters have improved the quality of care for patients with chronic illnesses, but are complicated by obstructions which can result in delay of treatment or catheter removal. DESIGN AND METHODS This paper reviews thrombolytic treatment for catheter obstruction. Literature from Medline searches using the terms "central venous catheter", "central venous acc...

Unusual case of peripheral venous occlusion.

Pulmonary embolectomy using normothermic venous inflow occlusion.

The introduction of cardiopulmonary bypass for the urgent removal of massive pulmonary emboli by Sharp (1962) revolutionized the surgical management of this emergency. More patients were successfully treated in the four years following this than in the preceding 50 years since Trendelenburg's (1908) classical description of pulmonary embolectomy. The use of an extracorporeal circulation, and ac...
