Extended mechanical compression device therapy linked with reduced DVT risk

Recently published results showed superior deep vein thrombosis prophylaxis among patients who underwent mechanical compression device therapy for up to 6 weeks after limited-tourniquet total knee arthroplasty compared with patients who had compression during hospitalization only.

Researchers randomly assigned 100 patients (60% were women) who underwent limited-tourniquet total knee arthroplasty (TKA) and received 325 mg of aspirin twice daily for 3 weeks to use of a mechanical compression device (VPULSE Compression and Cold Therapy System; Cothera LLC) either during hospitalization only or for up to 6 weeks postoperatively. To confirm the absence of deep vein thrombosis (DVT) after treatment, researchers performed lower extremity duplex venous ultrasonography on the second postoperative day, at 14 days postoperatively and at 3 months postoperatively.

Results showed patients who used the mechanical compression device after discharge had a significantly decreased risk of DVT at postoperative day 2 and week 2 vs. patients who used the device on an inpatient basis only. Researchers noted a total incidence of DVT of 23.1% in the inpatient group and of 0% in the post-discharge group. Patients in the post-discharge group used the mechanical compression device significantly longer and experienced a significant increase in patient satisfaction. – by Casey Tingle
