A woman with critical left main stenosis suffered intractable left internal mammary artery spasm post-coronary artery bypass grafting. This was managed with a left main stent and the patient stabilized. A 3-month follow-up angiogram showed a patent graft and a blocked stent.

A pilot study has been conducted in which coronary arteries subject to re-stenosis after angioplasty and stenting have been irradiated following further angioplasty. The method of irradiation has been to use radioactive 188Re in an angioplasty balloon. This paper considers all aspects of the procedure including elution of the rhenium from a tungsten/rhenium generator, its concentration, dispensing and safe delivery to the patient using specially designed equipment to reduce staff doses and radioactive spills.

Methods: All elderly patients undergoing PTCA between January 1984 and December 1990 were included. Data concerning the PTCA procedure and short term (hospital stay) outcome were compared to those of all patients less than 75 years who underwent PTCA during the same period.
Coronary arteries occluded by long lengths of thrombus are usually considered unattractive for angioplasty. Nine patients (8 male, mean age 50.1 years) undergoing angiography for unstable angina were found to have single vessel disease considered unsuitable for angioplasty as the vessel was occluded by a long length of thrombus.

Follow-up, defined as angiography at 6 months, earlier angiographic restenosis or coronary bypass surgery was completed by 108 aspirin- and 104 placebo-treated patients. Restenosis (stenosis greater than or equal to 50% plus loss of greater than or equal to 50% of gain, or surgery) occurred in 38 (35%) aspirin- and 45 (43%) placebo-treated subjects (p = not significant).
