Intravascular Rewarming in Major Burns: A Rare but Serious Catheter-Related Complication

<b>Introduction</b>: Patients with major burn injuries are highly susceptible to hypothermia due to extensive skin loss, aggressive fluid resuscitation, repeated surgical procedures, and exposure during wound care. Hypothermia is associated with coagulation disorders, increased blood loss, impaired immune response, prolonged hospitalization, and increased mortality. When conventional warming strategies fail, intravascular temperature management systems may be employed, although they carry risks inherent to central venous catheters. <b>Case Report</b>: We report the case of a 26-year-old male with 66% total body surface area flame burns and inhalational injury, admitted to the Burns Intensive Care Unit with persistent hypothermia despite standard warming measures. An intravascular temperature management catheter was inserted via the femoral vein and successfully restored normothermia. Due to clinical instability, the catheter remained in situ beyond the recommended duration. During attempted catheter removal, significant resistance was encountered, raising concern for mechanical malfunction. Imaging confirmed catheter entrapment without fracture. Multidisciplinary management involving vascular surgery and interventional radiology enabled successful removal using endovascular snare techniques. A detached balloon fragment was identified and secured with venous stenting. <b>Conclusions</b>: This report describes the first documented case of complicated removal of an intravascular warming catheter due to balloon detachment in burn patients. Physicians using these devices should be aware of this possible complication and be prepared for its management.
