The importance of the costoclavicular space in upper limb primary deep vein thrombosis, a study with magnetic resonance imaging (MRI) technique enhanced by a blood pool agent.

Background: Primary upper extremity deep vein thrombosis (UEDVT) can be divided into idiopathic and effort thrombosis. Anatomical factors probably play an important role in effort thrombosis, whereas the cause remains mostly unknown in idiopathic thrombosis.

Objectives: The primary objective of this study was to examine the anatomy of the subclavian region and evaluate how these factors contribute to primary UEDVT.

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.
