Catheter-Directed Thrombolysis in Acute Iliofemoral Deep Vein Thrombosis with or without Stenting: A Case Series
AbstractIliofemoral deep vein thrombosis (IFDVT) is a potentially devastating condition comprising a quarter of all cases of lower extremity DVT. It can lead to serious consequences such as pulmonary embolism, limb malperfusion, and post-thrombotic syndrome (PTS), which is a chronic sequela of IFDVT. We herewith present 18 IFDVT cases managed with catheter-directed thrombolysis at our hospital. Nine of these patients underwent stenting of the involved iliac veins. The remaining 9, who did not receive stenting, had a residual stenosis of more than 50% in the common femoral or iliac veins following the procedure. Based on a final residual stenosis of less than 50% in the iliac veins, we had 9 successful (patients with stenting) and 9 unsuccessful procedures (patients without stenting). In subsequent follow-ups at a median follow-up of 39.5 months, using the Villalta score, while only 2 out of the 9 patients who underwent stenting suffered PTS, 4 patients among the other 9 patients comprising the non-stenting group developed PTS. Our results support the notion that stenting might have a role in decreasing the PTS risk in patients undergoing catheter-directed thrombolysis.
