The Effect of Pump on Early Postoperative Mortality and Cerebrovascular Accident in Coronary Bypass Surgery Patients

Abstract

Introduction: This study investigated the mortality rates during the postoperative early period (one month) in patients who underwent on- or off-pump coronary artery bypass grafting (CABG) and explored the effects of cardiopulmonary bypass (CPB) on early mortality and cerebral accident.

Patients and Methods: This study comprises a total of 260 subjects that underwent CABG surgery in our clinic. Patients who underwent CABG were grouped according to two different surgical techniques: the first group (Group 1) consisted of patients who underwent CABG using CPB and cross-clamp (on-pump); the second group (Group 2) consisted of patients who underwent CABG by beating heart (off-pump) technique. Proximal anastomoses were performed using side clamps in all cases.

Results: Postoperative follow-up was conducted on patients until Day 30 for mortality. We encountered four dead cases and six cerebrovascular accidents.

Conclusion: The rates of cerebral accidents (2.4% vs. 2.1%) and deaths (1.8% vs. 1%) have the same ratios and are not statistically significant in on-pump CABG surgeries compared with off-pump CABG surgeries.

Açık Kalp Cerrahisinde, Pompanın Erken Postoperatif Mortalite ve Serebrovasküler Olay Üzerine Etkisi

Abstract

Giriş: Bu çalışma, son gelişmelerle pompalı/pompasız koroner arter baypas grafting (KABGO) uygulanan hastalarda, postoperatif erken dönemde (bir ayda), kardiyopulmoner baypas (KPB)'ın erken mortalite ve serebral olay üzerine etkileri araştırıldı.

Hastalar ve Yöntem: Çalışmamız, kliniğimizde koroner arter baypas greftleme ameliyatı yapılan toplam 260 olguyu içermektedir. KABGO uygulanan hastalar iki farklı cerrahi tekniğe göre gruplandırıldı. Birinci grup (Grup 1), CPB ve X klemp (on-pump) kullanılarak KABGO uygulanan hastalardan oluştu. İkinci grup (Grup 2), atan kalp (off-pump) tekniği ile KABGO uygulanan hastalardan oluştu. Proksimal anastomozlar tüm olgularda yan klemp kullanılarak yapıldı.

Bulgular: Hastalar postoperatif otuzuncu güne kadar mortalite açısından takip edildi. Dört ölüm olgusu ve altı serebrovasküler olayla karşı karşıya kaldık.

Sonuç: On-pump KABGO ameliyatlarında off-pump KABGO ameliyatlarına kıyasla serebral kaza oranları (%2.4’e karşı %2.1) ve ölüm (%1’e karşı %1.8) benzer oranda görülürken istatistiksel olarak anlamlı değildir.
