Ambulatory Venous Pressure Measurements for the Evaluation of Patients with Venous Ulcers
Monday, August 12, 2013

 

 

Ambulatory venous pressure measurements are used to investigate patients with venous stasis ulcers.  Ambulatory venous pressure measurements do not provide anatomical information but provide global hemodynamic information about the venous system in patients with venous stasis ulcers.  Ambulatory venous pressure measurements are invasive , unlike magnetic resonance venography, computed tomography, and plethysmography.

 

The normal venous pressure in foot veins are between 15 to 30 mmHg.  An elevated resting venous pressure indicates venous disease and  directly correlates with the severity of venous disease.

 

Generally, patients with venous stasis ulcers have venous pressure measurements between 45 to 60 mmHg.  The patients are asked to do 10 to 12 tip toe movements following which ambulatory venous pressure recovery time (RT) can be measured.  The recovery time of less than 18 seconds is considered pathological.

 

Ambulatory venous pressure measurements can be used to assess global venous function but is the most reliable physiologic tool for quantitating venous function.

 

Ambulatory venous pressure measurements are used for research purposes in vascular laboratories.

 

Foot veins are cannulated for this diagnostic study.

 

Venous Doppler ultrasonography is a noninvasive way to investigate patients with venous stasis ulcers.  Plethysmography is also a noninvasive technique to investigate patients with venous ulcers.

 

The most common type of plethysmography is strain gauge plethysmography. Other such as more graphic techniques are air plethysmography, foot volumetry, and light reflection rheography (also known as photo plethysmography).
