Transvenous Catheter-Based Thrombolysis With Continuous Tissue Plasminogen Activator Infusion for Refractory Thrombosis in a Patient With Behcet's Disease.

Behcet's disease (BD) classically presents with recurrent oral ulcers, genital ulceration, uveitis and skin manifestations. Middle-aged people are usually affected with the male gender being associated with severe variant of the disease. It can involve any organ system of the body. Although central nervous system and vascular involvement tend to occur less frequently, they are the commonest cause of mortality. We present a case of a 30-year-old man referred with suspicion of cerebral venous sinus thrombosis to our hospital and subsequently diagnosed with BD. The patient developed, despite being on immunosuppression and anticoagulation, extensive arteriovenous thrombi of lower limbs requiring catheter-directed thrombolysis with continuous 24-hour infusion of tissue plasminogen activator for refractory right lower limb venous thrombosis and placement of inferior vena cava filter to prevent pulmonary embolism. Later disease remission was achieved with rituximab.
