An Unusual Complication After Surgical Correction of Shepherd's Crook Deformity in a Young Woman: A Case Report and Literature Review

Cardiac events are rare, easily neglected, but potentially fatal complications of McCune–Albright syndrome. An 18-year-old woman underwent proximal femur osteotomy and intramedullary nail fixation for correction of shepherd's crook deformity at our institution. Unexpectedly, she developed acute heart failure on postoperative day 2. She had no preoperative cardiovascular abnormality and did not receive excessive fluids during the perioperative period. Pulmonary embolism was excluded based on spiral computed tomography pulmonary angiography. Her symptoms resolved on postoperative day 3. Genetic analysis of surgical tissue revealed that the patient had McCune–Albright syndrome.
