Accessory appendicular artery

The accessory appendicular artery (or artery of Seshachalam) is a branch of the posterior caecal artery, which in turn arises from the ileocolic artery, and runs in the mesoappendix.

The exact prevalence of this accessory artery and its impact upon the risk of appendicitis varies among studies. 

History and etymology

It is named after Dr T Sheshachalam who described it. Interestingly, it is the only anatomical structure named after an Indian.
