Karotis endarterektomide karşı taraf karotis arter tıkanıklığı bir risk faktörü müdür?

Amaç: Bu çalışmada karotis endarterektomi yapılan hastalarda karşı taraf karotis arter tıkanıklığının morbidite ve mortalite açısından ek risk oluşturup oluşturmadığı araştırıldı. Çalışma planı: Eylül 2010 - Mart 2015 tarihleri arasında kliniğimizde karotis darlığı tanısı ile ameliyat edilen toplam 135 hasta (103 erkek, 32 kadın; ort. yaş 68.3 yıl; dağılım 46-92 yıl) karşı taraf arterde tıkanıklık varlığına göre iki gruba ayrıldı. Endarterektomi uygulanan karotis arterinin karşı tarafında tıkanıklık olan 32 hasta ile karşı tarafında tıkanıklık olmayan 103 hasta ile karşılaştırıldı. Her iki grubun başlangıç demografik özellikleri, risk faktörleri, cerrahi teknik tipi, ameliyat sonrası erken dönem morbidite ve mortalite sonuçları karşılaştırıldı. Bulgular: Her iki grup demografik ve ameliyat sırası özellikler açısından benzerdi. Her iki grup arasında ameliyat sonrası hem nörolojik [karşı taraf karotis arterde oklüzyonu (CO) olan grup %6.3, kontrol grubu %6.8, p=0.638] hem nörolojik olmayan komplikasyon (CO grubu %15.6, kontrol grubu %12.6, p=0.430) açısından istatistiksel anlamlı fark saptanmadı. İki grupta da hastane kalış süresi arasında istatistiksel fark yok iken; tıkanıklık olan grupta yoğun bakım kalış süresi anlamlı uzun idi (p=0.029). Ameliyat sonrası mortalite açısından gruplar arasında (CO grubu %0, kontrol grubu %1, p=0.763) anlamlı fark saptanmadı. Sonuç: Karşı taraf karotis arter tıkanıklığı olan hastalarda serebral kan kaynağının sınırlı olması nedeniyle yüksek morbidite ve mortalite görüleceği düşünülse de özellikle ameliyat sonrası nörolojik komplikasyon açısından anlamlı bir artış görülmedi. Bu nedenle, karotis endarterektomisi uygulanacak hastalarda karşı taraf tıkanıklığının cerrahi açıdan ek bir risk oluşturmadığı kanaatindeyiz

Is contralateral carotis artery occlusion a risk factor for carotid andarterectomy?

Background: In this study, we aimed to investigate whether contralateral carotis artery occlusion poses an additional risk for morbidity and mortality in carotid endarterectomy. Methods: Between September 2010 and March 2015, a total of 135 patients (103 males, 32 females; mean age 68.3 years; range 46 to 92 years) who were operated with the diagnosis of carotid stenosis in our clinic were divided into two groups depending on the presence of an occluded contralateral artery. Thirty-two patients undergoing carotid endarterectomy with contralateral carotid artery occlusion were compared to 103 patients without contralateral occlusion. Baseline demographic characteristics, risk factors, type of surgical technique, postoperative early morbidity and mortality results of both groups were compared. Results: Both groups were similar according to their demographic and perioperative characteristics. There was no statistically significant difference in postoperative neurological [carotid occlusion group (CO) 6.3%, control group 6.8%, p=0.638] or nonneurological (group CO 15.6%, control group 12.6%, p=0.430) complications between the two groups. The length of hospital stay did not differ between both groups statistically while length of intensive care unit stay was significantly longer in the group with occlusion (p=0.029). There was no significant difference in the postoperative mortality between the groups (group CO 0%, control group 1%, p=0.763). Conclusion: Although morbidity and mortality are expected to be high in patients with contralateral carotid artery occlusion due to the limited cerebral blood supply, there was no significant increase in postoperative neurological complications, particularly. Therefore, we believe that contralateral occlusion does not pose an additional risk for surgery in patients undergoing carotid endarterectomy.
