BACKGROUND Oblique lateral interbody fusion surgery has become increasingly popular for lumbar degenerative diseases. The oblique corridor is between the psoas muscle and the retroperitoneal vessels, and its use could result in decreased tissue trauma, minimal blood loss, and short operation times. Patients who undergo oblique lateral interbody fusion surgery are always placed in the right lateral position to avoid damage to the inferior vena cava, which is typically a right-sided vessel. There is a substantial risk of vascular injury during the operation if there are anatomical variations in the vessels. CASE PRESENTATION A 77-year-old man, of the Han nationality, with lumbar spinal stenosis underwent stand-alone oblique lateral interbody fusion surgery. Transverse magnetic resonance imaging of the lumbar spine indicated that his inferior vena cava was left-sided. A three-dimensional reconstructed image of abdominal computed tomography angiography showed that the inferior vena cava was located on the left side. Finally, the surgeon decided to change the position of our patient from a right lateral position to a left lateral position before the surgery. CONCLUSIONS To date, this is the first reported case where a patient underwent oblique lateral interbody fusion surgery in a left lateral decubitus position due to a left-sided inferior vena cava. This case demonstrates that carefully reading radiological results is important for operation planning and avoiding anatomical complications.

左斜下腔静脉接受腰椎椎间融合手术的患者：一例。

背景技术斜向外侧椎间融合手术已经对于腰部退行性疾病越来越流行。斜走廊位于腰肌与腹膜后血管之间，使用斜走廊可减少组织创伤，减少失血量并缩短手术时间。进行斜向外侧椎体间融合手术的患者始终置于右侧位置，以免损坏下腔静脉（通常是右侧血管）。如果血管的解剖结构存在变化，则在手术过程中存在严重的血管损伤风险。病例介绍一名77岁的汉族男子，患有腰椎管狭窄症，接受了独立的斜外侧椎体间融合手术。腰椎的横向磁共振成像表明他的下腔静脉是左侧的。腹部计算机断层血管造影的三维重建图像显示下腔静脉位于左侧。最后，外科医生决定在手术前将患者的位置从右侧位置更改为左侧位置。结论迄今为止，这是首次报道的患者因左侧下腔静脉在左侧卧位进行斜外侧椎体间融合手术的病例。该病例表明，仔细阅读放射学结果对于手术计划和避免解剖并发症很重要。腹部计算机断层血管造影的三维重建图像显示下腔静脉位于左侧。最后，外科医生决定在手术前将患者的位置从右侧位置更改为左侧位置。结论迄今为止，这是首次报道的患者因左侧下腔静脉在左侧卧位进行斜外侧椎体间融合手术的病例。该病例表明，仔细阅读放射学结果对于手术计划和避免解剖并发症很重要。腹部计算机断层血管造影的三维重建图像显示下腔静脉位于左侧。最后，外科医生决定在手术前将患者的位置从右侧位置更改为左侧位置。结论迄今为止，这是首次报道的患者因左侧下腔静脉在左侧卧位进行斜外侧椎体间融合手术的病例。该病例表明，仔细阅读放射学结果对于手术计划和避免解剖并发症很重要。这是首次报道的病例，患者由于左侧下腔静脉在左侧卧位进行了斜外侧椎体间融合手术。该病例表明，仔细阅读放射学结果对于手术计划和避免解剖并发症很重要。这是首次报道的病例，患者由于左侧下腔静脉在左侧卧位进行了斜外侧椎体间融合手术。该病例表明，仔细阅读放射学结果对于手术计划和避免解剖并发症很重要。
