Figure 4. A, B, and C: Follow-up 26 hours after initial intervention showed continued improvement in clot burden. There was however residual thrombus and stenosis within the iliac and femoral veins, and repeat angioplasty with 10 French balloon was performed. Suction thrombectomy was again performed as previously described. Final venogram showed significant improvement in overall clot burden and luminal caliber with minimal nonocclusive thrombus seen in the iliac venous system.
