Summary
Pulmonary embolism, a rare complication of upper-extremity surgery, can be fatal. This case highlights deep venous thrombosis from prolonged immobilization as a cause following shoulder arthroplasty.
Area of Science:
- Orthopedic Surgery
- Vascular Surgery
- Critical Care Medicine
Background:
- Upper-extremity surgery, including shoulder arthroplasty, typically carries a low risk of thromboembolic events.
- Pulmonary embolism (PE) is a serious, though infrequent, complication that warrants careful consideration.
- Deep venous thrombosis (DVT) is a known risk factor for PE.
Observation:
- A case of fatal pulmonary embolism occurred postoperatively after shoulder arthroplasty.
- The pulmonary embolus was found to have originated from a deep venous thrombosis in the lower extremity.
- The patient experienced prolonged immobilization during the perioperative period.
Findings:
- The study identifies a link between prolonged immobilization and the development of lower-extremity deep venous thrombosis.
- This deep venous thrombosis subsequently led to a pulmonary embolism, resulting in a fatal outcome.
- The findings underscore the potential for unexpected thromboembolic complications even after procedures not traditionally associated with high DVT risk.
Implications:
- Clinicians should maintain a high index of suspicion for deep venous thrombosis and pulmonary embolism in patients undergoing upper-extremity surgery, especially those with prolonged immobilization.
- Enhanced DVT prophylaxis protocols may be necessary for specific patient populations undergoing shoulder arthroplasty.
- This case emphasizes the importance of comprehensive risk assessment and preventative strategies for thromboembolic disease across all surgical specialties.
