Abstract
Objective:
To observe the incidence of intra-operative vascular injuries during anterior cervical decompression and fusion (ACDF). Secondly, management and monitoring of the outcome post vascular injury during ACDF.
Methods:
This a prospective study. A review of all spinal patients' records was performed from June 2006 to April 2011. A comprehensive literature review was also utilized. Inclusion criteria – all patients had ACDF post trauma. All non-traumatic cases were excluded.
Results:
The study consisted of 55 patients; 15 were females and 40 were males. The age distribution was 23–65 years. Two patients were excluded due to non-traumatic causes. Of the remaining 53 patients, four sustained intra-operative vascular injuries during ACDF surgery. All 4 patients had corpectomies, and one case was an iatrogenic injury. The commonly injured vessel during the ACDF surgery was the left vertebral artery. Haemostatic control was achieved via tamponade and haemostatic agents. The left common carotid was iatrogenically injured in one case and was treated by microvascular repair. Three patients were treated with antiplatelet therapy for three months duration. The patient with an iatrogenic injury was treated with anticoagulation therapy for three months duration. All computerized tomographic angiograms at three months follow up illustrated patent vessels.
Conclusion:
There is an increased incidence of intra operative vascular injuries during ACDF associated with corpectomies. It is essential to be aware of the low incidence of intra operative arterial injury during ACDF and to have a management approach, such as tamponade or microvascular repair. Anticoagulation and antiplatelet therapy is effective in decreasing the complications of vascular injuries post ACDF.
