Objective To investigate the value of retention rate of indocyanine green at fifteen minutes (ICGR15) during hemihepatectomy for evaluation of residual liver reserve function in patients with primary liver carcinoma. Methods During hemihepatectomy, ICGR15 was tested in 44 patients after the hepatic artery and portal vein of resected side were ligated. Child-Pugh score, Child-Pugh classification, and MELD score before operation were tested. After operation, the liver function condition was estimated. Results The incidence of liver dysfunction was significantly lower in ICGR15lt;10% group (17.9%, 5/28) than that in 10%~15% group (75.0%, 12/16), Plt;0.05. There was no significant difference of Child-Pugh score among normal liver function group, mild insufficiency of liver function group, and severe insufficiency of liver function group （Pgt;0.05）. ICGR15 and MELD score in normal liver function group were statistical lower than those in mild insufficiency of liver function group and severe insufficiency of liver function group (Plt;0.05). ICGR15 was significantly lower in Child-Pugh A group than that in Child-Pugh B group (Plt;0.05). Conclusion Intraoperative residual liver ICGR15 may be more precisely compared with Child-Pugh score in evaluation liver reserve function for the patients with primary liver carcinoma and can help to guide liver resection.
【Abstract】ObjectiveTo evaluate the value of MR imaging with a contrast-enhanced multi-phasic isotropic volumetric interpolated breath-hold examination (VIBE) in diagnosis of primary liver carcinoma. MethodsThirty-two consecutive patients with surgical-pathologically confirmed 42 foci of primary carcinoma of liver underwent comprehensive MR examination of the upper abdomen, routine two-dimensional (2D) T1WI and T2WI images were acquired before administration of Gd-DTPA for contrast enhancement. Then, contrast-enhanced multi-phasic VIBE was acquired followed by 2D T1WI images. The lesion appearances on hepatic arterial, portal venous and equilibrium phases of VIBE sequence were carefully observed along with delineation of hepatic arterial and portal venous structures. The lesion detection rates and lesion characterization ability were compared among various MR sequences. Results33(78.6%), 30(71.4%), 38(90.5%) and 42(100%) foci were displayed respectively on T2WI, non-enhanced T1WI, enhanced T1WI and enhanced 3D-VIBE images (P＜0.05). The hepatic arterial anatomy of 30 patients （93.8%） and the portal venous structure of 31 patients （96.9%） were clearly depicted on enhanced 3D-VIBE images. Using MIP and MPR reconstruction techniques, the feeding arteries of 14 foci and draining vein of 12 foci were clearly displayed.ConclusionHigh-quality 3D-VIBE images are not only better than 2D images in lesion detection and characterization for primary liver carcinoma, but also able to provide much more information about hepatic vascular anatomy.
