Subclavian artery- internal jugular vein fistula and heart failure: complication of internal jugular vein catheterization.

Hemodialysis in patients with end-stage renal disease (ESRD) requires vascular access which can be either temporary or permanent. However, these procedures are not without complications. Arterial puncture is the most common immediate complication and pseudoaneurysm formation is the most common late sequel of internal jugular venous catheterization (IJVC). However, arterio-venous fistula (AVF) formatiorn following IJVC is rare. We are reporting a case of AVF formation between subclavian artery (SCA) and internal jugular vein (IJV) following IJVC which later on leads to the development of cardiac failure.
