Lesions of the external carotid artery situated in the more superficial structures do not have remarkable potentialities for derangement of the circulatory system nor do they result in intracranial hemorrhage. Nevertheless, the need for surgical intervention is at times considerable. 1. Exsanguination. In the normal scalp, the interlacing fibrous network prevents a retraction of the lacerated blood vessel, so that the loss of blood from even a small wound can at times be so great as to constitute a threat to life. The obvious hazard in this age of violence from the presence of a huge mass of engorged, elastin-deficient vessels in an exposed area of the body requires no elaboration (Fig. 10). Control of bleeding from a wound of these vessels is unquestionably beyond the scope of the physician in the emergency room, and long before a diagnosis can be established, the patient may die from hemorrhage. 2. Bruit. A subjective auditory complaint referred to the head is an almost invariable part of the symptom-complex, especially irritating to the patient when he rests his head against a pillow. Some describe the noise as booming, others liken it to a rhythmic tattoo on the head with a hammer. Although compatible with life, this exasperating symptom has a most distressing effect on the patient’s psychic resources.
