Vasopressin and fluid retention after liver resection: Comparison with the renin-angiotensin-aldosterone system by surgical extent and liver function

Figure 1 Perioperative changes in plasma aldosterone concentration and arginine vasopressin in all patients. A and B: Temporal changes in plasma aldosterone concentration (PAC) (A) and arginine vasopressin (AVP) (B) levels in all 56 patients undergoing liver resection. Both PAC and AVP increased significantly immediately after liver resection, followed by gradual normalization on postoperative day 5. Values were expressed as medians with interquartile ranges. ^aP < 0.01 vs preoperative baseline. PAC: Plasma aldosterone concentration; AVP: Arginine vasopressin; LR: Liver resection; POD: Postoperative day.
