The future liver remnant (FLR) volume and complications after portal vein embolization (PVE) were compared between the ipsilateral right portal vein (PTPE) and transileocolic (TIPE) approaches. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p> A total of 42 patients (TIPE, n = 22; PTPE, n = 20) underwent right lobectomy after PVE. CT and hepatobiliary scintigraphy were repeated before and after PVE. The blood examination findings and the FLR values (FLR<jats:sub>CT<\/jats:sub>: calculated from CT, %FLR<jats:sub>CT<\/jats:sub>: FLR<jats:sub>CT<\/jats:sub> ratio, %FLR<jats:sub>SPECT<\/jats:sub>: FLR ratio using single photon emission CT, FLR<jats:sub>CT<\/jats:sub>\/BS: FLR<jats:sub>CT<\/jats:sub> to body surface ratio) were compared between two approach sites. The complications and mortality were also analyzed after PVE and major right hepatectomy. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> There were no significant differences in the patient characteristics, blood examination findings or FLR values between two groups. Adequate liver regeneration was observed without significant differences between PTPE and TIPE (increased ratio of FLR<jats:sub>CT<\/jats:sub>: 8.7% vs 19.2%, p = 0.15 [25\u201375 percentile: 17.1\u201360.4], %FLR<jats:sub>CT<\/jats:sub>: 11.2% vs 8.3%, p = 0.25 [6.3\u201313.3], %FLR<jats:sub>SPECT<\/jats:sub>: 15.4% vs 19.2%, p = 0.09 [16.0\u201322.4], FLR<jats:sub>CT<\/jats:sub>\/BS: 33.6% vs 47.1%, p = 0.19 [17.2\u201360.4], respectively), but TIPE required a significantly longer procedure time than PTPE [181.4\u2009min vs 108.7\u2009min, p &lt; 0.01 (103.3\u2013193.5)]. However, one patient was converted to TIPE due to bleeding during PTPE. After right lobectomy, portal vein stenosis or thrombosis was noted in three patients [two with TIPE (9.1%) and one with PTPE (5%)] and three TIPE patients died within 90 days (13.6%) after right hepatectomy. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> FLR volume significantly increased after PVE, regardless of the approach sites; however, PTPE is a useful
