Analysis of radiographic and physical findings in 114 patients with trauma to an extremity demonstrated that when other physical findings are normal, arteriography is unnecessary. If any physical sign of peripheral vascular injury exists, such as weak or absent pulse, neurologic deficit, bruit, or expanding hematoma, arteriography is essential to define the anatomy and determine the need for surgery.
Fourteen patients are presented to illustrate the usefulness of ultrasonography in assessing masses of the neck. Included are five patients with primary tumors, two with metastasis to a cervical node, three with cervical adenitis, two with simple cysts, and two with hematoma related to endarterectomy for occlusive disease of the carotid artery.
Cerebral hyperperfusion and early draining veins directly resulting from status epilepticus can be demonstrated angiographically. Postmortem examination of the brain excluded other possible causes of hyperemia and early venous drainage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
