    Abstract

    Objective—To determine the usefulness of the Stack autopersion dilatation catheter in patients with acute recurrent vessel closure during coronary angioplasty.

    Design—Prospective data collection.

    Setting—University hospital.

    Patients—In 37 of 1003 consecutive patients undergoing angioplasty between November 1989 and December 1990 acute vessel closure developed that could not be redilated by a conventional balloon catheter. 13 (35%) of these 37 patients were sent immediately for emergency bypass surgery.

    Intervention—In the remaining 24 patients an attempt was made to reopen the vessel with a Stack catheter.

    Main outcome measure—Successful reopening of the vessel. All successfully treated patients were followed for at least six months to detect recurrent ischaemia.

    Results—In 16 patients (67%) the Stack procedure was successful. Of the eight patients in whom reopening of the occluded vessel was not achieved, seven were sent for bypass surgery and one was successfully treated by emergency stent implantation. The 16 patients successfully treated with the Stack autoperfusion system were followed up for a mean (SD) of 6·7 (2·6) (range 2 to 11) months. Ten patients remained symptom free but early clinical restenosis developed in four (25%). Overall, only three (19%) of 16 patients experienced recurrence of severe (class III-IV) symptoms and required further mechanical revascularisation.

    Conclusion—These data support the use of the Stack autoperfusion catheter system in selected patients with acute vessel closure not responsive to attempted redilatation with conventional balloon catheters. The short-term outcome seen in this series of patients who were successfully treated with this coronary autoperfusion system is encouraging.
