Benign obstruction of subclavian and axillary veins possibly due to filariasis.

This paper analyses the clinical features of 8 patients with post-thrombotic obstruction of the subclavian and axillary veins demonstrated by phlebography. The classic physical signs of swelling of the arm with dilated superficial collateral veins were seen. The causes of thrombotic obstruction are discussed and the precipitating cause in this study was possibly filariasis.
