Dipasang stenting atau terapi obat pada stenosis arteri intracranial?

Telah dilakukan penelitian untuk menilai kemanjuran antara operasi angioplasti dan pemasangan stanting dengan terapi obat pada pasien dengan stenosis arteri intracranial. NEJM edisi Minggu I septem ber 2011 telah melaporkan bahwa terapi obat pada pasien dengan stenosis arteri intracranial lebih menguntungkan jika dibandingkan dengan operasi angioplasti dan pemasangan stenting. Tidak dapat dipungkiri bahwa stenosis arteri intracranial merupakan faktor risiko utama kejadian stroke dan sering berakibat fatal. Makalah selengkapnya silakan baca di:

Background

Atherosclerotic intracranial arterial stenosis is an important cause of stroke that is increasingly being treated with percutaneous transluminal angioplasty and stenting (PTAS) to prevent recurrent stroke. However, PTAS has not been compared with medical management in a randomized trial.

Methods

We randomly assigned patients who had a recent transient ischemic attack or stroke attributed to stenosis of 70 to 99% of the diameter of a major intracranial artery to aggressive medical management alone or aggressive medical management plus PTAS with the use of the Wingspan stent system. The primary end point was stroke or death within 30 days after enrollment or after a revascularization procedure for the qualifying lesion during the follow-up period or stroke in the territory of the qualifying artery beyond 30 days.

Results

Enrollment was stopped after 451 patients underwent randomization, because the 30-day rate of stroke or death was 14.7% in the PTAS group (nonfatal stroke, 12.5%; fatal stroke, 2.2%) and 5.8% in the medical-management group (nonfatal stroke, 5.3%; non–stroke-related death, 0.4%) (P=0.002). Beyond 30 days, stroke in the same territory occurred in 13 patients in each group. Currently, the mean duration of follow-up, which is ongoing, is 11.9 months. The probability of the occurrence of a primary end-point event over time differed significantly between the two treatment groups (P=0.009), with 1-year rates of the primary end point of 20.0% in the PTAS group and 12.2% in the medical-management group.
