Abstract

Objectives: Although short-term results of renal angioplasty with stent placement are well-established in the treatment of renovascular hypertension, its long-term effects remain controversial. In this study, we aimed to evaluate the long-term effects of stent therapy on blood pressure control in renal artery stenosis. Study design: The study included 26 patients (17 males, 9 females; mean age 59 years; range 43 to 75 years) who had renovascular hypertension and ostial-proximal arteriosclerotic renal artery stenosis above 70%. Twenty-five patients had unilateral stenosis. The mean stenosis rate, stent diameter, length, and follow-up period were 83.2±5.9 percent, 7.11±0.3 mm, 15.36±2.2 mm, and 2.8 years, respectively.Results: The procedure was fully successful with no major adverse events. Three patients (11.5%) died during the follow-up period. Although the mean systolic and diastolic pressures significantly decreased at 24 hours after stenting, no significant differences were noted between the values measured at 24 hours and those obtained in the following period (p>0.05). Blood pressure was controlled by 81% within nine months, and by 69% throughout the follow-up period, during which medicaments were discontinued in six (23.1%), were reduced in 12 (46.2%), remained unchanged in four patients (15.4%), and were increased in one patient (3.9%). The mean creatinine level showed an insignificant decrease (p>0.05). Two patients developed restenosis (7.7%) which was treated with by balloon angioplasty. Conclusion: Our findings suggest that the beneficial effect of stent placement on blood pressure is not confined to the short-term in renal artery stenosis.

Özet

Amaç: Renovasküler hipertansiyon tedavisinde renal anjiyoplasti-stent uygulamasının, kısa dönem sonuçları bilinmesine karşın, uzun dönemdeki etkileri tartışmalıdır. Çalışmamızda, renal arter stenozunda stent uygulamasının kan basıncı kontrolü üzerine uzun dönemdeki etkisi incelendi. Çalışma planı: Çalışmaya, ostial-proksimalde %70’in üzerinde aterosklerotik renal arter darlığı bulunan renovasküler hipertansiyonlu 26 hasta (17 erkek, 9 kadın; ort. yaş 59; dağılım 43-75) alındı. Yirmi beş hastada tek taraflı darlık vardı; Darlık oranı ortalama %83.2±5.9 idi. Ortalama stent çapı 7.11±0.3 mm, stent uzunluğu 15.36±2.2 mm idi. Hastalar ortalama 2.8 yıl izlendi.Bulgular: Hiçbir olguda hastane içi önemli olay gelişmedi. İşlem başarısı %100 idi. İzlem döneminde üç hasta (%11.5) öldü. Sistolik ve diyastolik kan basıncı ortalamaları, işlem öncesine göre işlemden sonra 24. saatte anlamlı düşüş göstermesine karşın, işlemden sonraki 24. saat ile izleyen aylarda elde edilen değerler arasında anlamlı farklılık görülmedi (p>0.05). Kan basıncı kontrolünde ilk dokuz ayda %81, uzun dönemde ise %69 düzelme sağladı. Uzun dönem izlemde kullanılan ilaçlar altı olguda (%23.1) kesildi, 12 olguda (%46.2) azaltıldı, dördünde (%15.4) değişmedi, bir olguda (%3.9) ise artırıldı. İşlemden sonra ortalama kreatinin düzeyinde anlamlı olmayan düşüş görüldü (p>0.05). İki hastada (%7.7) yeniden gelişen darlık balonla tedavi edildi. Sonuç: Renal arter stenozu tedavisinde stent uygulamasının kan basıncı üzerindeki olumlu etkileri uzun dönemde de sürmektedir.
