A follow-up study of the fate of small asymptomatic deep venous thromboses.

Background: Postoperative asymptomatic deep venous thromboses (ADVT) can give rise to posttthrombotic syndrome (PTS), but there are still many unresolved issues in this context. For example, there is a lack of knowledge regarding the fate of small ADVT following minor orthopedic surgery. This follow-up study evaluates postthrombotic changes and clinical manifestations of PTS in a group of patients with asymptomatic calf vein DVT after surgery for Achilles tendon rupture.

Hemodynamic and morphologic evaluation of sequelae of primary upper extremity deep venous thromboses treated with anticoagulation.

Objectives: This study was performed to describe venous function, residual morphologic abnormalities, and the occurrence of post-thrombotic syndrome in patients with conservatively treated primary upper-extremity deep venous thromboses (UEDVT).

Method: This was a retrospective follow-up study of 31 patients with previous primary UEDVT treated with anticoagulation only, identified by a search of medical records. The mean follow-up time was 5 years.

A methodological study of computerized venous strain-gauge plethysmography of the upper extremities.

This study was performed to assess the efficiency of computerized strain-gauge plethysmography for evaluation of venous volume (VV) and outflow capacity of the upper extremities and to receive reference values. For this purpose, we investigated 34 healthy controls; 16 males and 18 females with a mean age of 45 years (range 31-58 years). These results were compared with those obtained in 32 patients with earlier spontaneous deep venous thrombosis (DVT) in the upper extremities.
