# Iatrogenic Superior Vena Cava Syndrome With Extensive Thromboembolism Associated With Chronic Indwelling Catheterization

## TL;DR

This paper discusses a case of a rare condition caused by a blood clot from a long-term IV catheter, leading to severe breathing issues.

## Contribution

The paper presents a novel case of iatrogenic SVCS due to catheter-related thromboembolism.

## Key findings

- SVCS can result from chronic catheterization leading to extensive thromboembolism.
- The case highlights the need for monitoring intravascular devices to prevent complications.

## Abstract

Superior vena cava syndrome (SVCS) results from the partial or complete obstruction of blood flow through the superior vena cava (SVC), which comprises a broad clinical spectrum ranging from asymptomatic cases to rare life-threatening emergencies with upper airway obstruction and increased intracranial pressure. Iatrogenic SVCS is not uncommon given the increasing utilization of intravascular devices in the past decades, suggesting that wider knowledge of the indications for semipermanent venous access and consistent monitoring are warranted in our clinical practice in order to avoid unfavorable outcomes. Here, we present a case of SVCS with respiratory distress due to extensive thromboembolism associated with a chronic indwelling intravenous (IV) catheter.
