“…Preoperative evaluation: In addition to routine preoperative studies to determine the indications for L5-S1 fusion, midsag-ittal T1- and T2-weighted MRI images of the sacrum and coccyx were performed to rule out a vascular anomaly or tumor. 25 , 26 , 35 Evaluation of the sagittal curve of the sacrum is necessary to confirm the feasibility of the approach ( Fig. 1 ).…”

BackgroundThe presacral retroperitoneal approach to an axial lumbar interbody fusion (ALIF) is a percutaneous, minimally invasive technique for interbody fusion at L5-S1 that has not been extensively studied, particularly with respect to long-term outcomes.ObjectiveThe authors describe clinical and radiographic outcomes at 1-year follow-up for 50 consecutive patients who underwent the presacral ALIF.MethodsOur patients included 24 males and 26 females who underwent the presacral ALIF procedure for interbody fusion at L5-S1. Indications included mechanical back pain and radiculopathy. Thirty-seven patients had disc degeneration at L5-S1, 7 had previously undergone a discectomy, and 6 had spondylolisthesis. A 2-level L4-S1 fusion was performed with a transforaminal lumbar interbody fusion at L4-5 in 15 patients. AxiaLIF was performed as a stand-alone procedure in 5 patients and supplemented with pedicle screws in 45 patients. Pre- and postoperative visual analog scale (VAS) and Oswestry Disability Index (ODI) scores were evaluated and complications were tracked. Fusion was evaluated by an independent neuro-radiologist.ResultsAt 1-year follow-up, VAS and ODI scores had significantly improved by 49% and 50%, respectively, versus preoperative scores. By high-resolution computer tomography (CT) scans, fusion was achieved in 44 (88%) patients, developing bone occurred in 5 (10%), and 1 (2%) patient had pseudoarthrosis. One patient suffered a major operative complication–a bowel perforation with a pre-sacral abscess that resolved with treatment.ConclusionOur initial 50 patients who underwent presacral ALIF showed clinical improvement and fusion rates comparable with other interbody fusion techniques; its safety was reflected by low complication rates. Its efficacy in future patients will continue to be monitored, and will be reported in a 2-year follow-up study of fusion.

Introduction: Lumbar veins drain blood from the abdominal wall and vertebral venous plexus into inferior vena cava, ascending lumbar veins, renal veins or lumbar azygos vein. Case report: We report the presence of a common lumbar vein which received the right and left third lumbar veins and left second lumbar vein.It passed in front of the body of third lumbar vertebra and drained into the posterior aspect of inferior vena cava. Conclusion: During surgical procedure of lumbar region such as the anterior approach of lumbosacral and lumbar disc spaces, injury to such a large common lumbar venous trunk may occur leading to disastrous bleeding complications and this can be avoided by prior radiographic and imaging studies.

“…Cho et al evaluated, in a cadaver study, the anatomical features of iliac vessels with respect to the anterior approach to the LS spine. Only 60% of the specimens were judged to have easy accessibility to the LS spine 25 . Ebraheim et al called the retroperitoneal space anterior to the LS junction the "triangular safety zone".…”

Aim. The aims of this study were to describe the incidence and type of perioperative complications that occur with minimally invasive anterior retroperitoneal spinal surgery performed at the level of the L5/S1 intervertebral disc. Methods. A retrospective review of 175 patients: 103 women and 72 men, average age 45, who had undergone anterior spinal surgery at level L5/S1 from January 2001 to February 2011. The preoperative diagnoses were: degenerative disc disease in 87 (50%), failed back surgery syndrome in 53 (30%) and spondylolisthesis in 35 patients (20%). The surgical steps in the minimally invasive anterior retroperitoneal approach from the right side to disc L5/S1 are described. All surgical intraoperative anatomical anomalies and complications directly related to the anterior spinal surgery were documented. Results. Intraoperative pathological-anatomical anomalies were found in 34 patients (19%) and intra -and postoperative minor complications in 24 patients (12%) but no serious complications. The main intraoperative complication was peritoneal opening without visceral injury (5%) and the main postoperative complication was weakness of the right abdominal wall (3%). Conclusion. Retroperitoneal access and surgery at level L5/S1 disc space is a safe procedure when performed by a knowledgeable and experienced spine team. During surgical planning for an anterior approach to the LS spine, the surgeon must carefully assess the neuroimaging results, such as MRI, to minimize potentially disastrous vascular complications.
