A preliminary experience on the efficacy, safety, and short-term results in the treatment of acute bilateral iliofemoral deep vein thrombosis with the Angiojet rheolytic thrombectomy.

OBJECTIVE

This study aimed to examine the early clinical outcomes of AngioJet rheolytic thrombectomy (RT) in patients with acute bilateral iliofemoral deep vein thrombosis (IFDVT), with a specific focus on the incidence of post-thrombotic syndrome.

METHODS

From March 2021 to August 2023, 16 consecutive patients with acute bilateral IFDVT treated with AngioJet RT at our center were evaluated. Primary outcomes include patency of the target veins, development of post-thrombotic syndrome, recurrent DVT, and procedure-related death. Secondary outcomes included minor or major bleeding, acute kidney injury, documented hemoglobinuria, cardiac event, pulmonary embolism, limb loss, and death.

RESULTS

The mean age of the patients was 69 ± 12 years (range, 53-87 years). Malignancy and recent major surgery were the most prevalent risk factors, each observed in 25% of patients (n = 4). Technical success, complete clot removal, and alleviation of symptoms were achieved in all patients (n = 16; 100%). In one-quarter of the patients (n = 4), transient hemoglobinuria was observed following the procedure. This complication resolved spontaneously after adequate fluid replenishment. Minor bleeding occurred in three patients (19%), whereas no patients had major bleeding complication. There was one postoperative acute kidney injury and transient bradycardia (6%). Three patients died after the procedures (19%). One patient (6%) developed postoperative massive pulmonary embolism. The mean follow-up was 11 ± 6 months (range, 5-19 months). The primary patency rate was 92% and 91%, respectively, 6 and 12 months after procedures. One patient had reocclusion during the follow-up.

CONCLUSIONS

AngioJet RT applied to patients with bilateral IFDVT provides a promising picture, providing a patent vein lumen with high procedural success and achieving convincing early symptomatic improvement in severely symptomatic patients with impaired quality of life. In this early case series, the feasibility of the AngioJet device in elderly cases appears to be a significant problem. Therefore, patient selection is essential.
