Özet
Amaç: SPECT'in (single photon emission computed tomography) iskemik stroktaki prognostik değerini tayin etmek amacı ile 1998-2000 yılları arasında geçirilmiş strok nedeniyle motor defisiti olan 42 hastada strok'tan 72 saat sonra BT (Bilgisayarlı Tomografi) ve/veya MRG (magnetik rezonans görüntüleme) yanısıra SPECT incelemesi yapıldı. Gereç ve Yöntem: Hastalardan 34'ünün 4 ay ile 24 ay arasında değişen sürelerde (ortalama 10 ay) kontrol motor muayeneleri yapıldı. SPECT bulgularının hem nörolojik tablo, hem BT ve/veya MRG bulguları ile hem de takibi yapılan hastalarda prognoz ile olan ilişkisine bakıldı. Bulgular: SPECT'te ileri hipoperfüzyon (%60'ın üzerinde perfüzyon kaybı) gözlenen vakaların %87.5'inde ileri motor defisit olduğu ve bu defisitin hastaların %78.9'unda düzelmediği, buna karşı hafif-orta hipoperfüzyon (%60 ve altında perfüzyon kaybı) varsa hastaların %88.9'unda orta veya hafif motor defisiti olduğu ve hastaların %80'inin fonksiyonel olarak düzeldiği görüldü. SPECT'de ileri hipoperfüzyonu olan hastaların hepsinde BT ve/veya MRG'de infarkt görülürken, hafif-orta hipoperfüzyonu olan hastalarda bu oran %73.7'ye düşmekteydi. Sonuç: SPECT bulguları ile nörolojik tablonun korelasyon gösterdiği, radyolojik görüntüleme yöntemleriyle saptanamayan lezyonların SPECT ile gösterilebileceği ve SPECT'in prognozu belirlemede önemli bir tanı yöntemi olduğu kanaatine varıldı.
Purpose and method: In order to evaluate the prognostic value of SPECT (single photon emission computed tomography) in ischemic stroke patients, we reviewed the neurological examinations, CT (computed tomography), MRI (magnetic rezonance imaging) and SPECT scans of 42 stroke patients which are performed between 1998 and 2000. All SPECT scans had been performed after 72 hours. 34 patients came back for control neurological examination. The mean time interval between the SPECT evaluation and control neurological examination was 10 months (ranging between 4 to 24 months). Results: The 87.5% of patients that had perfusion defect above 60% had severe motor deficit and 78.9% of these patients could not recover. Conversely 88.9% of the patients that had perfusion defect below 60% (mild to moderate) had mild or moderate motor deficit and 80% of these patients exhibited good recovery. All of the patients with severe hypoperfusion had positive findings in radiological examination while 73.7% of the patients with mild to moderate hypoperfusion had positive findings. Conclusion: SPECT findings showed good correlation with neurological status and prognosis. The ischemic lesions which can not seen in CT and MRI examination, can be detected by SPECT.
