Q

This structure is highly vulnerable in surgical manipulation of the ductus arteriosus
a. Esophagus
b. Left vagus nerve
c. Left bronchus
d. Left recurrent laryngeal nerve

A

d. Left recurrent laryngeal nerve

Patent Ductus Arteriosus is the failure of ductus arteriosus to close and become “ligamentum arteriosum”. The left recurrent laryngeal nerve arises from the left vagus trunk as the nerve crosses the arch of the aorta. It hooks around the ligamentum arteriosum and ascends in the groove between the trachea and the esophagus on the left side
