Simultaneous Thrombolysis and Venous Angioplasty in Acute Ilio-femoral Thrombosis after IVC filter Insertion and Novel Balloon Catheter Models

Mark Arokiaraj, Luis Guerrero, Robert Levine and Igor Palacios

Four patients with extensive acute iliofemoral and popliteal vein thrombosis and partially extending into the inferior venacava (IVC) with diffuse swelling of lower limb and gluteal region were studied. Initially, Gunther Tulip (Cook) IVC filter was placed in all patients. A 5F multipurpose catheter with side holes was placed in common iliac vein bifurcation and thrombolysis was done for 18 hours with diluted streptokinase infusion at 50,000 U/hr. Thereafter, a 5 mm × 4 cm peripheral balloon was advanced through the clots to mid or lower femoral vein level and thrombolysis was done for 18 hours with streptokinase infusion through the balloon’s 035 wire port. The balloon was pulled back and multiple serial dilatations were done in all four procedures. Post procedure the venous channels were opened and were draining adequately. Limb edema subsided in 4 to 5 days and there were no bleeding or embolic complications in all patients. The first two patients are on follow up for 18 months, the third patient for 5 months, and the fourth patient for 2 weeks. Based on these observations, two novel balloon models for thrombolysis and to perform venous angioplasty simultaneously were developed. The piggyback model has a side lumen catheter with side holes attached to the shaft of the balloon catheter (5 mm width × 4 cm length ). The side lumen terminates before the balloon. The horseshoe models made of polyethylene terephthalate have a 10 cm long and 4 mm wide compliant balloon with a double lumen catheter and multiple side ports till the balloon tip.
