Arterial epistaxis.

Area of Science:

• Vascular Surgery
• Otolaryngology
• Anatomy

Background:

• Epistaxis (nosebleeds) can be challenging to manage, particularly when the bleeding source is not immediately identifiable.
• Arterial ligation is a common surgical intervention for severe epistaxis.
• Understanding nasal arterial supply and potential variations is crucial for successful treatment.

Purpose of the Study:

• To discuss the rationale and implications of ligating specific arteries for epistaxis management.
• To highlight anatomical considerations and potential complications of arterial ligation in the nose.
• To explain vascular changes associated with persistent epistaxis in the elderly.

Main Methods:

• Review of anatomical considerations for nasal arterial supply.
• Discussion of surgical strategies for epistaxis, including external carotid and maxillary artery ligation.
• Analysis of factors contributing to persistent epistaxis, including arterial anastomoses and age-related vascular changes.

Main Results:

• Ligation of the external carotid or maxillary artery is a viable initial approach for unidentified nasal bleeding sites.
• Persistent bleeding post-ligation may be due to arterial anastomoses, not necessarily incorrect vessel ligation.
• The anterior ethmoidal artery is absent in a notable percentage of individuals, impacting ligation strategies.
• Age-related vascular changes, including collagenous changes and calcification, contribute to chronic epistaxis in the elderly.

Conclusions:

• Surgical management of epistaxis requires careful consideration of arterial anatomy and potential anastomoses.
• Variations in arterial presence, such as the anterior ethmoidal artery, must be acknowledged.
• Age-related vascular pathology plays a significant role in the persistence of nosebleeds in older adults.
