Arm vein thrombosis.

With the advent of subclavian catheterization for the supportive care of a host of diseases, the incidence of axillosubclavian vein thrombosis (ASVT) is rising. Treatment of these patients is not standard. Spontaneous ASVT usually occurs in healthy young individuals, often results in long-term disability, and warrants aggressive intervention. Catheter-induced ASVT generally occurs in older individuals with other significant medical problems.
