The patient developed respiratory distress 13 days postoperatively and was admitted to another institution, where she was diagnosed with pulmonary embolism and was subsequently therapeutically anticoagulated with heparin. The patient complained of right-leg numbness and tingling 18 days’ postoperatively, which progressed to complete sciatic nerve palsy over several hours.
