A Cadaveric Study of Anatomical Variations in the Arterial Supply of Vermiform Appendix

Abstract

Acute appendicitis is the most common cause of acute abdomen in young adolescents and appendectomy is often the first major surgical procedure performed by a surgeon. Precise knowledge of vascular variation and planning of conducting surgical and radiological procedures is important during appendectomy. The appendicular artery is considered to be a branch from posterior caecal artery or ileocolic artery entering the mesoappendix from behind the ileum and supplying it. There is no general agreement in the literature about the arterial blood supply of the vermiform appendix. Little information is available in the literature about the distribution and pattern of branching of the appendicular arteries. In view of the discrepancies in the literature about the anatomy of the vascular supply of the appendix and to add further knowledge of surgical anatomy this study was carried out. Accessory arteries are important because they can provide some immunity toward appendicitis. Detailed analysis of the arterial vascularization of the appendix is necessary before its removal for reconstructive microsurgery.

The presence and the anatomical variations of the accessory appendicular artery: A systematic review of 604 cases

“…We noted this source in 12.4% of the total cases, a remarkably higher occurrence compared with the other origins. The prevalence of the specific origin was affirmed by 7 out of 11 studies (excluding Nirmaladevi and Seshayyan, 14 Kalamutharasi 16 and Sudha et al, 17 while Kumari and Srinivas 13 reported an equivalent frequency with the ileal branch). An occurrence of 2% is attributed to the descending branch of the ileocolic artery, which is situated before its division into the cecal arteries.…”

“…Therefore, our systematic review included 11 studies. [8][9][10][11][12][13][14][15][16][17][18] All studies were performed in Asia and were published between 1930 and 2022. The population of specimens ranged from 20 to 100.…”

The Impact of Smoking on the Complications of Acute Appendicitis

“…The length of appendix varies from 2 to 20 cm with an average of 9 cm, microscopically the vermiform appendix is a muscular tube containing a large amount of lymphoid tissue. 1 The appendix is suspended by a peritoneal fold called mesoappendix covering its variable length and carrying the blood supply to the organ, by appendicular artery, a branch derived from ileocolic artery. The appendicular artery is an end artery; hence the inflammation of the appendix the vascular thrombosis may produce gangrene of its tip.…”

“…The appendicular artery is an end artery; hence the inflammation of the appendix the vascular thrombosis may produce gangrene of its tip. 1 Acute appendicitis is one of the most common causes of abdominal pain in emergency departments. Acute uncomplicated and complicated appendicitis are epidemiologically and clinically different disease entities.…”
