Sensitive carotid sinus.

In 1968, a head-injured male, age 20, suffered four cardiac arrests in rapid succession after undergoing the performance of a cerebral arteriogram by the injection of radiopaque material into the common carotid artery in the neck. Several attempts at injection were required before a clear flow was obtained. It was assumed that these several needle stabs in the vicinity of the carotid sinus caused damage to this critical area, resulting in the cardiac arrests. After a precarious few hours, he made a successful recovery and was known to be alive and working 28 years later.

Spinal adhesive arachnoiditis.

Forty-one cases of spinal adhesive arachnoiditis are presented. The key points are, first, that lumbar disc lesions, their investigations and surgical treatment and the use of nonabsorbable contrast materials are the most common etiological factors and, secondly, that operation is the best treatment. It is our contention that the majority of patients so treated do experience some improvement in what otherwise can be an unbearable amount of pain and disability. The use of adsorbable, nonirritative contrast materials such as Iohexol Parenteral will result in a marked reduction in the frequency of occurrence of arachnoiditis.
