Abstract
Introduction
Due to co-morbidities in elderly like atherosclerosis and approach-related risks, anterior lumbar surgery is mainly recommended for younger patients. We reviewed approach-related complications in anterior lumbar surgery in senior patients for complex reconstructions.
Materials and Methods
Retrospective review of 12 patients (8 female and 4 male), mean age 65.5±4.9 years, treated with anterior fusion mainly for degenerative scoliosis and lumbar kyphosis in between 2007-10. 9(75%) patients had multilevel procedures. Most common co-morbidities were atherosclerosis (CT-proven in 7 patients), coronary heart disease and COPD. Renal impairment was present preoperatively in 3 patients.
Results
Mean duration of surgery was 260±120.8 min and mean blood loss 403.3±348.0 ml in the whole group (157±49.1 min and 240.0±162.0 ml in single ALIF; 334.0±100.0 min and 520.0±408.0 ml in multilevel procedures). Retractor related ischaemia occurred in 8 patients (27.3±29.1 min); perfusion of the leg returned immediately after release (confirmed via pulse-oxymetry). 2 patients had a direct vessel suture (2 common iliac veins); hypotension during surgery occurred in 1 patient due to anaesthetic problems. 5 patients needed ICU support after the procedure. Superficial wound infection was reported in one patient. One case of incisional hernia and one case of lymphocele was noticed.
Conclusion
In this retrospective review, no specific complications concerning age or co-morbidities occurred in senior patients. In this group, atherosclerosis was the most common co-morbidity. However, no arterial embolism or perfusion deficit occurred. In the future, more and more elderly are to be treated by spinal surgeons. Anterior lumbar surgery is an alternative treatment option even for complex cases in the elderly. This limited group of patients need further investigations and prospective studies regarding anterior lumbar surgery.
