Analysis of the efficacy of angiojet percutaneous mechanical thrombectomy combined with catheter-directed thrombolysis versus catheter-directed thrombolysis alone in the treatment of subacute iliofemoral deep venous thrombosis in elderly patients.

PURPOSE

To analysis the clinical efficacy of Angiojet percutaneous mechanical thrombectomy (PMT) combined with Catheter-Directed Thrombolysis (CDT) compared to CDT in treatment of subacute iliofemoral deep venous thrombosis (IFDVT) in elderly patients.

METHODS

A retrospective analysis of the clinical data of 117 elderly patients hospitalized for subacute IFDVT was conducted. The patients'basic perioperative data and 2-years follow-up data were compared.

RESULTS

Group A (PMT + CDT) had a more patients reaching Grade III thrombus clearance, and a lower thrombolysis time, dosage of thrombolytic drugs, hospital stay, and bleeding incidence compared to Group B (CDT). There was a statistically significant difference in the occurrence rate of severe PTS within 2 years ( < 0.05).

CONCLUSION

In treating elderly patients with subacute IFDVT, PMT + CDT effectively reduces the thrombus burden and the dosage of thrombolytic drugs, shortens the hospital stay, and importantly, reduces the occurrence rate of severe PTS within 2 years.
