Pleural Effusion in Spinal Deformity Correction Surgery- A Report of 28 Cases in a Single Center


To analyze the occurrence, risk factors, treatment and prognosis of postoperative pleural effusion after spinal deformity correction surgery.The clinical and imaging data of 3325 patients undergoing spinal deformity correction were collected from the database of our hospital. We analyzed the therapeutic process of the 28 patients who had postoperative pleural effusion, and we identified the potential risk factors using logistic regression.Among the 28 patients with postoperative pleural effusion, 24 (85.7%) suffered from hemothorax, 2 (7.1%) from chylothorax, and 2 (7.1%) from subarachnoid-pleural fistula. The pleural effusion occurred on the convex side in 19 patients (67.9%), on the concave side in 4 patients (14.3%), and on both sides in 4 patients (14.3%). One patient with left hemothorax was diagnosed with kyphosis. The treatment included conservative clinical observation for 5 patients and chest tube drainage for 23 patients. One patient also underwent thoracic duct ligation and pleurodesis. All of these treatments were successful. Logistic regression analysis showed that adult patients(≥18 years old), congenital scoliosis, osteotomy and thoracoplasty were risk factors for postoperative pleural effusion in spinal deformity correction surgery.The incidence of postoperative pleural effusion in spinal deformity correction surgery was approximately 0.84% (28/3325), and hemothorax was the most common type. Chest tube drainage treatment was usually successful, and the prognosis was good. Adult patients(≥18 years old), congenital scoliosis, and had undergone osteotomy or surgery with thoracoplasty were more likely to suffer from postoperative pleural effusion
