Abstract
Purpose
Acute arterial thrombosis after hip arthroplasty is a rare event associated with potentially catastrophic complications. Early clinical diagnosis of progressive limb ischemia is often difficult in the immediate postoperative period because of residual neuraxial blockade and the nonspecific nature of signs. We describe the use of point-of-care ultrasound (POCUS) in the postanesthesia care unit (PACU) to diagnose this complication early and facilitate timely intervention.
Clinical features
A 78-yr-old female patient underwent elective right hip revision arthroplasty under spinal anesthesia and postoperatively had an absent dorsalis pedis pulse on her operative leg as screened by an audible-only Doppler. No obvious clinical symptoms were present as the patient was still under subarachnoidal blockade. A bedside POCUS vascular evaluation was performed in the PACU and showed an absence of blood flow in the superficial femoral artery, expediting the confirmation of a surgical emergency. The patient underwent a successful open thrombectomy and made an uneventful postoperative recovery.
Conclusion
Our case report highlights the novel use and impact of bedside POCUS to assess the presence or absence of distal limb arterial blood flow and, in this case, the level of arterial occlusion.
