Novel Percutaneous Mechanical Thrombectomy Device for Treating Upper Extremity Deep Vein Thrombosis in Patient With Paget-Schroetter Syndrome.

Paget-Schroetter Syndrome (PSS) is a form of upper extremity deep vein thrombosis (DVT) caused by the external compression of the subclavian vein at the thoracic outlet. Here we describe a complex PSS case in a 43-year-old female who experienced multiple recurrent DVTs and a right-sided hemothorax following two continuous aspiration thrombectomy procedures and a first rib resection. Rapid and complete symptom resolution was achieved with the InThrill Thrombectomy System (Inari Medical), a novel, thrombolytic-free, percutaneous mechanical thrombectomy device that removed all recurrent acute and subacute thrombus in a single session without significant blood loss.
