Purpose: To evaluate the safety and efficacy of portal vein embolization (PVE) with sodium tetradecyl sulfate (STS) foam.
Materials And Methods: A single-center retrospective review of 35 patients (27 men and 8 women; mean age, 61 y) who underwent PVE with STS foam was performed. The technical success rate, rate of PVE at producing adequate future liver remnant (FLR) hypertrophy, and rate of disease progression precluding resection after PVE were analyzed. Complications of PVE and liver resection after PVE were recorded.
Results: PVE was performed on 35 patients before right hepatic resection for both primary and secondary hepatic malignancies (22 hepatocellular carcinoma, 10 metastasis, 2 cholangiocarcinoma, 1 invasive gallbladder carcinoma). Technical success was achieved in 97.1% (34 of 35) of patients. Mean FLR of the total estimated liver volume increased from 24.5% (SD, 7.7%) to 36.5% (SD, 14.5%), a mean percentage increase of 48.8% (SD, 34.3%). PVE produced adequate FLR hypertrophy in 31 of 35 patients (88.6%). Proposed right hepatectomy was subsequently performed in 27 patients (77.1%). One patient remains scheduled for surgery, two had peritoneal spread at surgery and resection was aborted, two had disease progression on imaging after PVE, and three had inadequate FLR hypertrophy with no surgery. One major complication was observed related to PVE that involved nontarget embolization to segment III, which was managed conservatively.
Conclusions: Preoperative PVE with STS foam is a safe and effective method to induce hypertrophy of the FLR.

Objectives: To study the correlation between sarcopenia and hypertrophy of the future liver remnant(FLR) in patients undergoing portal vein embolization(PVE) before liver resection, and to assess the outcomes after resection.
Methods: This retrospective study examined patients underwent PVE from May 2012 to May 2023. Demographic, clinical and laboratory features were documented and total liver volumes(TLV) and FLR volumes were measured before and 2-4 weeks after PVE.

Aim: Compare the efficacy and procedural efficiency of central vascular plug-assisted portal vein embolization (PVE) with absolute ethanol compared to selective PVE.
Materials And Methods: Between 2016 and 2023, patients who underwent ipsilateral percutaneous transhepatic PVE were included. Selective PVE involves serial cannulation and embolization of portal veins.

Background: Post-hepatectomy liver failure (PHLF) is the first cause of death after major hepatectomy, and future liver remnant (FLR) volume is the main factor predicting PHLF. Liver venous deprivation (LVD) via portal and hepatic vein embolization has been suggested to induce a better hypertrophy of the FLR than portal vein embolization. The aim of this retrospective multicentric study was to assess safety, feasibility and efficacity of LVD in a French national multicentric register.

Objectives: This study aimed to develop and externally validate a model for predicting insufficient future liver remnant (FLR) hypertrophy after portal vein embolization (PVE) based on clinical factors and radiomics of pretreatment computed tomography (CT) PATIENTS AND METHODS: Clinical information and CT scans of 241 consecutive patients from three Swedish centers were retrospectively collected. One center (120 patients) was applied for model development, and the other two (59 and 62 patients) as test cohorts. Logistic regression analysis was adopted for clinical model development.

Background: Liver venous deprivation (LVD) is known to induce better future liver remnant (FLR) hypertrophy than portal vein embolization (PVE). The role of LVD, compared with PVE, in inducing FLR hypertrophy and allowing safe hepatectomy for patients with extensive colorectal liver metastases (CLM) and high-risk factors for inadequate hypertrophy remains unclear.
Methods: Patients undergoing LVD (n = 22) were matched to patients undergoing PVE (n = 279) in a 1:3 ratio based on propensity scores, prior to planned hepatectomy for CLM at a single center (1998-2023).
