ABSTRACT
Objective: To present our surgical experience and technique in performing endoscopic sinus surgery for vascular sinonasal tumors without pre-operative embolization using intraoperative ligation of the external carotid artery or its distal branches.
Methods:
Design: Retrospective Series
Setting: Tertiary Private Teaching Hospital
Participants: Seven Patients
Results: Out of 7 patients (5 males, 2 females, aged 12 to 64 years old) with non-embolized vascular sinonasal tumors, 2 had juvenile angiofibroma, 3 had a benign vascular tumor (hemangiopericytoma, hemangioma and a vasoformative solitary fibrous tumor), and 2 had a malignancy (rhabdomyosarcoma, squamous cell carcinoma). Four (57.1%) had external carotid artery ligation, two (28.6%) had internal maxillary artery ligation and one (14.2%) had sphenopalatine artery ligation. The mean intraoperative blood loss was 2447.1 mL (range 900mL to 5,000mL) and average operation duration was 7.6 hours (range 2.9 hours to 14.5 hours). The average amount of transfused blood products was 1785.7mL (zero to 3,000mL). The average hospital stay was 7 days (range 2 to 13 days) with one post-operative complication (ICU admission for hypotension from intraoperative blood loss).
Conclusion: Intraoperative ligation of the ECA or its distal branches to disrupt the vascular supply of sinonasal tumors may provide a viable means of preventing excessive intraoperative blood loss in patients with non-embolized vascular sinonasal tumors.
