Open management of massive venous bleeding in anterior lumbar spine surgery-a narrative review.

BACKGROUND AND

OBJECTIVE

Anterior lumbar spine surgery (ALSS) provides multiple benefits for the patient with spinal pathology. Vascular complications are uncommon and usually managed with simple surgical techniques and ancillary products. Rarely, confronting massive haemorrhage can occur after a venous injury which endangers the patient. We aimed to review the anatomical basis and risk factors for venous injury, propose a staged, systematic approach for management and discuss open surgical techniques, instruments, products, and strategies in detail for each of the stages.

METHODS

This was a narrative review. A systematic approach was used. A review of national databases (PubMed, Ovid Medline, and Google Scholar) was performed using literature from 2000 to 2024 in English. Keywords included terms "anterior", "lumbar", "spine", "haemorrhage", "venous injury", "vascular", "repair", "ligation", "damage control", and "venous thromboembolism". Studies that aimed to describe the anatomy, risk factors, incidence, surgical techniques, complications, clinical and radiological outcomes of ALSS were included. Other generalised searches, not included in the initial systematic search, were conducted and included in our narrative review.

KEY CONTENT AND FINDINGS: This review considers the relevant anatomy, risk factors, patient work-up, lists possibly useful instruments and consumables, the broad stages of open management, specific operative strategies and techniques, and the post-operative management of the patient.

CONCLUSIONS

Massive venous injury (MVI) in ALSS is a rare but potentially life-threatening complication. Multiple open surgical techniques can be employed to control and manage the injury(s). The surgical and anaesthetic teams should have formulated a unified contingency plan against the eventuality of massive venous haemorrhage. The best outcome is only achieved with a team approach to the situation, recruitment of the necessary personnel and the deployment of the necessary equipment to enable the open management.
