INDIGO: Safety and Efficacy of Thrombolysis in Combination With Endhole Aspiration in the Treatment of Acute DVT
Study Details
Study Description
Brief Summary
The purpose of this study is to demonstrate the safety and efficacy of thrombolysis in combination with endhole aspiration in the treatment of acute deep vein thrombosis (DVT). Secondarily, the study team hope to illuminate the financial implications of single session catheter directed therapy versus a potential 48 hour lysis procedure (Lysis is an approach in which vascular specialists deliver clot-dissolving drugs directly to the site of the clot through a catheter).

Other: Treatment The treatment protocol the study team will be following is as follows for all enrolled patients. First, a pulse spray tPA infusion with 20 cc of 8 mg tPA and saline will be administered to the thrombus with a 20-minute dwell time. Afterwards, an 8F curved sheath (Indigo 8 Torq Tip, ranges 85 to 115 cm) with CAT8 penumbra device will be used to aspirate the thrombus. If the operating physician deems necessary, they will have the option at that point to balloon plasty, stent, or use catheter-directed thrombolysis at this point. Clinical parameters such as areas of clinically-significant stenosis, extent of thrombus, (more parameters) will be tracked at the time of the procedure. The device is being used is FDA approved and being used according to FDA indications. |

Outcome Measures
Primary Outcome Measures
- Post-thrombotic Syndrome (PTS) severity using the Villalta score [1 month]
Patient outcomes will be measured through clinical grading of PTS severity using the Villalta score, a clinical measure for the post-thrombotic syndrome that grades the severity, from 0 (absent) to 3 (severe), of each of 5 patient-rated symptoms (pain, cramps, heaviness, pruritus, and paresthesia) and 6 clinician-rated clinical signs (edema, redness, skin induration, hyperpigmentation, venous ectasia, and pain of calf). A summative score of 5 or more on the Villalta scale indicates the presence of the postthrombotic syndrome (Villalta).
