Management of Thoracic Outlet Syndrome Patient on Anticoagulation Undergoing Surgery

Understanding the Patient's Condition

Thoracic outlet syndrome (TOS) is a condition caused by compression of neurovascular structures at the superior thoracic outlet, according to the American College of Radiology 1
The patient is on anticoagulation, suggesting venous TOS with possible thrombosis requiring anticoagulation, as indicated by the Journal of Thrombosis and Haemostasis 3

For patients on anticoagulation requiring surgery, the anticoagulant should be discontinued before the procedure, as recommended by the American College of Cardiology 4
Anticoagulation should be stopped 12-24 hours before planned surgery to minimize bleeding risk, according to the American College of Cardiology 4
For patients with upper limb deep vein thrombosis (DVT), the standard initial treatment is 3 months of anticoagulation, as stated by the Journal of Thrombosis and Haemostasis 3
Postoperatively, anticoagulation can be restarted once adequate hemostasis is achieved, typically 12-24 hours after surgery, as recommended by the American College of Cardiology 4

Factors that may increase perioperative risk in this patient include the severity of the TOS and duration of anticoagulation therapy prior to surgery, as indicated by the Journal of Thrombosis and Haemostasis 3
Close monitoring for signs of recurrent thrombosis or bleeding complications is essential in the perioperative period, according to the Journal of Thrombosis and Haemostasis 3

Resume anticoagulation once adequate hemostasis is achieved, typically 12-24 hours after surgery, as recommended by the American College of Cardiology 4
Long-term anticoagulation may not be necessary if the TOS is surgically corrected or if the initial thrombotic event was provoked and has resolved, as stated by the Journal of Thrombosis and Haemostasis 3

Do not continue anticoagulation up to the time of surgery due to increased bleeding risk, as warned by the American College of Cardiology 4
Do not delay resumption of anticoagulation for too long after surgery in patients with high thrombotic risk, as cautioned by the Journal of Thrombosis and Haemostasis 3
