Outpatient coronary stent implantation

[摘要] Objectives. This study was performed to explore the feasibility of coronary Palmaz-Schatz stent implantation on an outpatient basis. Background. To optimize the applicability of coronary stenting by limiting bleeding complications and length of hospital stay, the transradial approach has been demonstrated to be an effective technique, Immediate ambulation opens the way to outpatient treatment. Methods. Patients selected for Palmaz-Schatz stent implantation received anticoagulation with Coumadin. At an international normalized ratio > 2.5, stenting was performed through the radial approach. Starting in December 1994, patients were treated with Ticlopidin. Heparin was administered during the procedure. Suitability for same day discharge was assessed on the basis of preprocedural, postprocedural and periprocedural criteria. Patients were mobilized after immediate sheath removal, followed by same-day discharge. Follow-up examinations were performed the nest day, at 2 weeks and at 1 month after stenting. Results. Of 188 patients who underwent Palmaz-Schatz coronary stent implantation through the radial artery between May 1994 and July 1995, 88 remained in the hospital for various reasons. In the 100 outpatients (Canadian Cardiovascular Society classes III and IV, n = 90 [90%]), 125 stents had been implanted to cover 110 lesions. No cardiac or bleeding events were encountered within 24 h (95% confidence interval 0 to 3.6) of stenting. At 2-week follow up, one patient was readmitted (day 4) because of a bleeding abdominal aortic aneurysm requiring operation. Two patients were readmitted 2 weeks after discharge, one with subacute thrombosis and one with angina and anemia that was treated with blood transfusions. At 1-month follow up, no complications were observed. Conclusions. After an optimal transradial Palmaz-Schatz coronary stent result, patients can safely be discharged on the day of treatment.
