Summary
Postoperative sympathetic chain dysfunction (PSCD) after oblique lateral lumbar interbody fusion (OLIF) occurred in 5.7% of patients. Lumbar dextroscoliosis and "tear-drop" psoas were identified as key risk factors.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Postoperative sympathetic chain dysfunction (PSCD) is a known complication of anterior lumbar fusion.
- Manipulation near the lumbar sympathetic chain (LSC) during surgery is implicated.
- Oblique lateral lumbar interbody fusion (OLIF) is a surgical technique with potential risks to the LSC.
Purpose of the Study:
- To determine the incidence of PSCD following OLIF surgery.
- To identify independent risk factors associated with PSCD after OLIF.
Main Methods:
- Retrospective review of 210 patients undergoing OLIF at L4/5.
- Patients were categorized into PSCD and non-PSCD groups.
- Binary logistic regression analysis was used to identify risk factors.
Main Results:
- The incidence of PSCD after OLIF was 5.7% (12/210 patients).
- Lumbar dextroscoliosis (OR=7.907) and "tear-drop" psoas (OR=7.216) were identified as independent risk factors for PSCD.
Conclusions:
- Lumbar dextroscoliosis and "tear-drop" psoas are significant risk factors for PSCD post-OLIF.
- Preoperative assessment of spinal alignment and psoas morphology is crucial for PSCD prevention.
