Temporary bilateral carotid artery occlusion as an aid to nasal surgery in the horse.

This research article discusses the use of temporary bilateral carotid artery occlusion as a measure to reduce bleeding during intranasal surgery in horses, improving the efficacy and outcomes of the surgery.

Reason for the Study

• The study was conducted due to the major challenge of haemorrhage or extreme bleeding during intranasal surgery in horses.
• Even minimal interventions in such surgeries could lead to profuse bleeding, hindering the procedure.
• Standard techniques for haemostasis, or blood flow control, are either ineffective or restrict the progression of the operation.

Methodology

• The study involved the temporary bilateral occlusion or blockage of the common carotid artery in the horse.
• This process was performed during intranasal surgery on five horses.

Findings

• Results showed a significant decrease in haemorrhage during the surgery, providing better visibility and ease of operation.
• The researchers noted that a substantial contribution to the circle of Willis by the ventral spinal artery may prevent cerebral ischaemia, a condition whereby insufficient blood flow to the brain leads to the death of brain tissue, during this procedure.

Conclusion and Recommendations

• The paper explains the technique of temporary bilateral ligation of the common carotid artery.
• It underscores the significance of additional methods such as packing of the nasal cavity and handling post-operative care.
• The successful operations on the five horses suggest that the technique could be a valuable approach during nasal surgery in horses.
