...Marine first lieutenant, Freeman was leading a combat patrol of about 30 men through thick, enemy-rife jungle. From behind a tree about 40 ft. away, a Japanese soldier shot Freeman in the jaw. The bullet ripped through his throat, passing between the jugular vein and the carotid artery. Doctors doubted whether Freeman would ever be able to talk normally again, but he went through a prolonged course of speech therapy and, being an exceedingly determined man, developed into a strong-voiced orator...
...carotid arteries that channel blood through the neck to the brain are almost as subject to atherosclerotic disease with advancing age as are the coronaries. They may simply be narrowed, so that less blood gets through. They may be almost closed by a fatty plaque, so that a clot forms there and clogs an artery. About 85% of strokes are caused by arterial shutdowns; about 10% by hemorrhage (bleeding through a burst blood vessel in the brain, usually in victims of high blood pressure), and 5% by traveling clots in the bloodstream...
...strokes as coronary attacks. Meanwhile, neurologists are working with surgeons to see what can be done about narrowed arteries in the neck, where the surgeon can get at them. From 5% to 20% of strokes (doctors differ widely about the proportion) occur not in the brain but in the carotid arteries in the neck. Houston's Dr. Michael E. DeBakey has pioneered with a series of operations to restore full blood flow through a narrowed carotid-by installing a bypass, or cutting out the narrowed stretch, or putting in a patch graft to widen the artery. But evaluation...
...that side loses its vision. The doctor presses against the eyeball with the ophthalmodynamometer until the patient reports that he cannot see out of that eye. The instrument registers the pressure at which vision was cut off. This in turn indicates the pressure in the internal carotid artery and shows whether that vessel is dangerously narrowed. If it is, a DeBakey operation may prove to be the answer...
Instant Benefit. Dr. Overholt has done the Nakayama operation on 160 patients since May of 1958. Only in three cases has he felt it necessary to remove both carotid bodies. That the glomus is a respiratory control center is suggested by the fact that some patients feel relief the instant.the body is removed, or even earlier, when it is inactivated by an injection of procaine (Novocain). More than 75% of all patients get some relief, reports Dr. Overholt; and in 50% or more, the relief is significant and sometimes dramatic. All his patients have been asthmatics for whom no other...
