Surgery of the aorta and its branches.

WITHIN the last 25 years, with improved methods of examination and treatment and better understanding of the functional alterations, it has become possible to diagnose and treat arterial disease before ischemic tissue is irreparably damaged. Two fundamental lesions of the aorta or its main branches are amenable to surgical correction: aneurysm and occlusive disease. We will consider briefly some aspects of the epidemiology and pathophysiology of arterial disease and at greater length the anesthetic and surgical problems associated with the more commonly treated lesions.

It has been shown that with suitable doses of decamethonium, succinylcholine, or succinylmonocholine, a two‐phase neuromuscular block can always be seen in isolated human intercostal muscle.
