Questionnaires were sent retrospectively to patients who had undergone day-case angiography at a British teaching hospital to evaluate the complications suffered after leaving hospital. In 1992, 5F catheters were used in 61 day-case patients. On analysis of the responses and detailed follow-up in areas of concern, no unexpected complication was found. It is concluded that day-case angiography using 5F catheters is associated with low morbidity after discharge home.
