Background . This retrospective study was designed to investigate the efficacy and safety of intermittent portal triad clamping (PTC) with low central venous pressure (CVP) in liver resections.  Methods . Between January 2007 and August 2013, 115 patients underwent liver resection with intermittent PTC. The patients' data were retrospectively analyzed.  Results . There were 58 males and 57 females with a mean age of 55 years (±13.7). Cirrhosis was found in 23 patients. Resections were performed for malignant disease in 62.6% ( n  = 72) and for benign disease in 37.4% ( n  = 43). Major hepatectomy was performed in 26 patients (22.4%). Mean liver ischemia period was 27.1 min (±13.9). The mortality rate was 1.7% and the morbidity rate was 22.6%. Cumulative clamping time ( t  = 3.61,  P  < 0.001) and operation time ( t  = 2.38,  P  < 0.019) were significantly correlated with AST alterations (D-AST). Cumulative clamping time ( t  = 5.16,  P  < 0.001) was significantly correlated with D-ALT. Operation time ( t  = 5.81,  P  < 0.001) was significantly correlated with D-LDH.  Conclusions . Intermittent PTC under low CVP was performed with low morbidity and mortality. Intermittent PTC can be safely applied up to 60 minutes in both normal and impaired livers.
