This protocol covers catheter-associated upper-extremity deep vein thrombosis (UEDVT) — DVT that develops in the context of an indwelling central venous catheter or port system. The presence of the catheter shapes both the anticoagulation strategy and the question of whether the catheter itself should be removed.
Catheter-associated UEDVT represents the predominant secondary form of upper limb DVT. It arises mainly from indwelling central venous lines or port systems, and less frequently from pacemaker or defibrillator leads. Management must account for the ongoing clinical need for the catheter alongside the thrombotic event.
The approach centers on anticoagulation therapy, with individualized decisions about whether to retain or remove the central venous catheter based on specific clinical circumstances. For cases where catheter patency is compromised, additional targeted interventions may be considered. The structured protocol covers the complete decision framework — including the conditions that guide catheter management and the sequencing of interventions.
