This is the first prospective study to document how often deep vein thrombosis occurs after shoulder arthroplasty. 100 consecutive patients underwent 4-limb surveillance Doppler ultrasound at day 2 and again at 12 weeks. The study asks whether VTE risk after shoulder replacement approaches that of hip and knee arthroplasty.
The key number to remember: DVT occurs in roughly 13% of shoulder arthroplasties, putting it on par with hip replacement rather than the low-risk procedure many assume. This matters because clinical guidelines for VTE prophylaxis after shoulder arthroplasty did not exist when this paper was written, and it provided the first prevalence data to inform them.
Watch two territories: the operative arm (axillary vein DVT presenting as pain and swelling) and both calves (distal vein clots). A clot can form in either. The fatal PE at 7 weeks with a negative day-2 scan is the teaching case. A normal early Doppler does not clear a patient. Maintain suspicion for PE when new dyspnea or tachyarrhythmia develops through the subacute period.
Appraise this cautiously: n=100 with no preoperative screening and only half screened at 12 weeks. Risk-factor analysis was underpowered, so age, weight, operative time, and prior VTE only trended toward significance.
