Spinal canal obstruction detected by cerebrospinal fluid imaging

Abstract

Following an uneventful intra-cavernosal injection of six micrograms of alprostadil, he developed satisfactory penile erection. But 20 min after the injection, he developed chest pain. He was taken to the nearest accident & emergency hospital where he was initially diagnosed as having unstable angina. Serial creatine kinase levels were 145 Uj L, 794 UjL, and 243 UjL (the laboratory referrence range was 24-190 UjL). Creatine Kinase MB Isoenzyme level was 51 UjL (reference range: 0-16); percentage of total Creatine Kinase was 6.4% (reference range: 0.4-4.0).Serial ECG was suggestive of lateral wall myocardial infarction. There were no signs of cardiac failure. There was an uneventful recovery and he was discharged home in a stable condition and has been attending our follow-up clinic and has been doing well. He was advised not to use alprostadil to achieve penile erection; he and his wife agreed to this suggestion.
