Abstract

Objective: Takayasu arteritis (TA) is a large vessel vasculitis that affects the aorta and its main branches in the young population. Although data about the effects of controlling disease activity with immunosuppressive treatments on cerebral circulatory capacity are limited, these treatments might stabilize the cerebrovascular hemodynamic status, regardless of the severity of proximal arteriopathy. One of the causes might be the normalization of cerebral autoregulation by the treatment. Materials and Methods: Cerebral vasomotor reactivity (cVMR) was calculated using the breath holding index (BHI) after bilateral middle cerebral artery (MCA) flow pattern was detected using transcranial Doppler ultrasound (TCD) in six patients with TA who were stabilized with treatment (age: 29±7 years, 5 female). A total of 28 measurements were performed. The control group included 18 healthy volunteers, except for migraine (29±6 years, 12 female). Bilateral MCA mean flow rates (Vmean, cm/s), pulsatility indexes (PI) and BHI were compared using non-parametric statistical methods. Results: Middle cerebral artery Vmean and PI values were lower in patients with TA (48.3±17.2 cm/s and 0.31±0.16, respectively) compared with the controls (62.2±11.3 and 0.70±0.11, respectively) (both p

Özet

Amaç: Takayasu arteriti (TA) genç yaşlarda arkus aorta ve dallarının tutulumu ile karakterize bir büyük damar vaskülitidir. İmmünosüpresif tedaviler ile hastalık aktivitesinin kontrol altına alınmasının serebral dolaşım üzerine etkisi konusunda yayınlar oldukça sınırlı olup, bu tip tedaviler ile proksimal arteriopati sekeline karşın serebrovasküler hemodinamik status stabilize edilebilmektedir. Bunun nedenlerinden biri serebral mikrosirkülatuvar otoregülatuvar kapasitenin tedavi ile normale dönüşü olabilir. Gereç ve Yöntem: Tedavi ile kontrol altında TA tanısı olan 6 hastada [yaş (ortalama ± standart sapma): 29±7 yıl; 5 kadın] transkraniyal Doppler ultrasonografi (TCD) ile her iki orta serebral arter (OSA) akım paterni tespit edildikten sonra nefes tutma indeksi (NTI) ile serebral vazomotor reaktivite (sVMR) çalışıldı. Altı hastada toplam 28 sVMR ölçümü yapıldı. Kontrol grubu migreni olması dışında sağlıklı olan 18 kişiden oluşturuldu (yaş: 29±6 yıl; 12 kadın). Her iki taraf OSA ortalama akım hızı (Vortalama, cm/s), pulsatilite indeksi (PI) ve NTI değerleri non-parametrik istatistiksel yöntemlerle karşılaştırıldı. Bulgular: OSA Vortalama ve PI değerleri sırasıyla, TA grubunda 48,3±17,2 cm/s ve 0,31±0,16 olup kontrol grubundan (62,2±11,3 cm/s ve 0,70±0,11) düşük olarak saptandı (her iki; p
