Abstract

Objective: A majority of ischemia strokes are related to atherosclerosis of extracranial cerebral arteries. Success of carotid endarterectomy to prevent strokes, is related to selection of appropriate patients based on colour Doppler ultrasonography (CDU) and magnetic resonance angiography (MRA). CDU is acccepted on the initial screening method, the aim of this study is; if MRA will catch the success of conventional cervical arteriography. Materials and Methods: In our study, 27 patients who had carotid artery bruits in Siyami Ersek Chest and Cardiovascular Surgery Hospital were included. 27 patients had CDU scrutiny. Among them 13 patients had MRA scrutiny. ATL-3500 HDI ultrasonography, 5-12 Mhz lineer probe was used in CDU scrutiny. Thirteen patients who had 60-79% or • 80-99% area reduction in internal carotid artery were scrutinized with MRA. In MRA scrutiny, 1.5 tesla superconductive magnets and TOF or intravenous contrast material injection Fast-SPGR sequences were used. Results: All 27 patients were investigated with CDU and 13 patients had MRA. Each patient, either alone CDU or CDU-MRA cooperation showed severe (60-79%) or critical (80-99%) stenosis. Stenotic values were confirmed with operation observations. Conclusion: We advice CDU to whom had bruits in carotid arteries, and confirm CDU findings with MRA and direct patients to CEA with no need invazive conventional arteriography.

Özet

Amaç: İskemik inmelerin çoğunluğu ekstrakraniyal serebral arterlerin aterosklerozu ile ilişkilidir. Karotis endarte-rektominin (CEA) inmeleri önlemedeki başarısı, renkli Doppler ultrasonografi (RDU) ve manyetik rezonans anjiyografi (MRA) tetkikleri ile uygun hastaların seçilmesi esasına dayanır. RDU başlangıç tarama testi olarak kabul edilir; çalışmamızın amacı, MRA ve RDU'nun konvansiyonel servikal arteriografinin (CA) başarısını yakalayabileceğini belirlemektir. Gereç ve Yöntem: Çalışmaya Siyami Ersek Göğüs Kalp Damar Cerrahisi Hastanesi'nde, karotis arterlerinde üfürüm saptanan 27 hasta dahil edildi. Yirmi yedi hastaya RDU ve içlerinden 13 hastaya MRA yapıldı. RDU tetkikinde ATL 3500 HDI ultrasonografi cihazı, 5-12 Mhz lineer probe kullanıldı, internal karotis arterde alan olarak %60-79 (şiddetli) ve %80-99 (kritik) düzeyde darlık saptanan hastalar MRA ile tetkik edildi. MRA tetkikinde 1.5 tesla supercon-duktive magnetler ile TOF veya intravenöz kontrast madde enjeksiyonu ile Fast-SPGR sekansları kullanıldı. Bulgular: 27 olgunun tamamına RDU ve 13'üne MRA uygulandı. Her hastada ya tek başına RDU ile ya da RDU-MRA beraberliğinde şiddetli (%60-79) veya kritik (%80-99) darlık izlendi. Operasyon gözlemleri ile darlık değerleri teyit edildi. Sonuç: Şüpheli internal karotis darlığı olan hastalarda ilk tetkik olarak RDU yapılmalıdır. Şiddetli veya kritik darlıkla uyumlu kantitatif değerleri saptanan hastalarda tek başına RDU, CEA tavsiye etmek için yeterlidir. Ancak yanlış pozitifliği en aza indirmek için ek tetkik olarak MRA yapılması operasyona alınacak hastalarda tanı doğruluğunu artıracaktır (1). Konvansiyonel arteriografi RDU ve MRA sonuçları uyumsuz olan durumlarda yapılmalıdır.
