POPLITEAL VEIN COMPRESSION SYNDROME

Latest Care for Thrombosis

DVT is considered to be a change in structure of the blood to form a very firm jelly like substance, and thought to be accounted for by 3 factors 1. blockage or restriction of flow, 2. Change in the blood vessel wall from trauma, inflammation, or infection, 3, Changes in the blood and these seem to be mainly related to Cancer of many types.  This group of causes is known as Virchow's Triad.

It is interesting that the majority of DVT occur in and around the knee in a large proportion of cases including the idiopathic group that have the most significant recurrence rate.

The majority of cases have no evidence of group 2. or group 3. factors and therefore blockage or restriction of flow is most likely.

At our clinic we have been examining patients for probable cause for about 10 years. The problem is Occlusion of the POPLITEAL VEIN when the knee is extended in the sitting position. The usual position for patients in prolonged bed rest when very ill, after surgery particularly knee surgery, it is more pronounced in obesity because of hypertrophied gastrocnemius muscles, it occurs in long flights when individuals go to sleep with their legs outstretched, common in economy but now occurring in business and first class with flat beds and strange sleeping positions. It occurs in the left leg of long distance drivers who have their left leg outstretched over long distances in Australia, the brake and accelerator are on the right. We have had young patients present after building cinemas in their homes with chairs that extend the legs whilst sitting and if immobile with a few beers present with massively swollen legs having watched some hours of movies. Heart Failure and other forms of leg swelling are typically met with directions to stay immobile sit, take it easy and keep the legs up ;a prescription for disaster unless the knees are flexed and most people including doctors think that the straight leg enhances blood flow. We estimate from our ultrasound studies that the predilection for this problem in our population which we have called "The POPLITEAL VEIN COMPRESSION SYNDROME'' is about 30% and it is certainly seen in the greater proportion of our patients with DVT and Pulmonary Embolus.

Dr David Huber published his findings that in the standard supine position of patients on the operating table with silastic heel supports the incidence of total POPLITEAL VEIN OCCLUSION is 40%
