Temporary bilateral carotid artery occlusion as an aid to nasal surgery in the horse
Insights
Hemorrhage during equine intranasal surgery can be significantly reduced by temporarily blocking both common carotid arteries. This technique improves surgical visibility and ease of operation, aiding in successful outcomes.
Area of Science:
- Veterinary Surgery
- Equine Medicine
- Surgical Hemostasis
Background:
- Hemorrhage is a major challenge in equine intranasal surgery, often hindering procedures.
- Existing hemostatic methods are frequently inadequate or impede surgical progress.
Purpose of the Study:
- To evaluate the efficacy of temporary bilateral common carotid artery occlusion in reducing hemorrhage during equine intranasal surgery.
- To assess the impact of this technique on surgical visibility and operational ease.
Main Methods:
- Temporary bilateral ligation of the common carotid arteries was performed in five horses undergoing intranasal surgery.
- Ancillary techniques including nasal cavity packing and comprehensive postoperative management were emphasized.
Main Results:
- A substantial reduction in hemorrhage was observed during intranasal surgery.
- Surgical visibility and the facility of operation were significantly improved.
- Cerebral ischemia was not observed, likely due to collateral circulation via the ventral spinal artery to the circle of Willis.
Conclusions:
- Temporary bilateral common carotid artery occlusion is an effective method for controlling hemorrhage in equine intranasal surgery.
- This technique enhances surgical conditions, contributing to improved surgical outcomes.
- Proper patient management, including postoperative care, is crucial for success.
Abstract:
One of the major obstacles to successful intranasal surgery in the horse is haemorrhage, even minor interferences causing profuse bleeding. Conventional techniques for haemostasis are ineffective or inhibit the progress of the surgery. Temporary bilateral occlusion of the common carotid artery resulted in a substantial reduction in haemorrhage during intranasal surgery in five horses, with much improved visibility and facility of operation. The large contribution to the circle of Willis by the ventral spinal artery is believed to prevent cerebral ischaemia during this procedure. This paper describes the technique of temporary bilateral ligation of the common carotid artery and emphasises the importance of ancillary techniques such as packing of the nasal cavity and general postoperative management.
