A 36-year-old female underwent sigmoidectomy and insertion of an intra-hepatic arterial catheter for advanced sigmoid cancer with multiple liver metastases. After the operation, intra-hepatic arterial infusion of the chemotherapeutic agents that showed sensitivity in the histoculture drug response assay (HDRA) to the liver metastasis was done for one year. The metastatic liver lesions other than those in the lateral segment which were fed by an accessory artery decreased remarkably. Therefore, we performed lateral segmentectomy. The patient has been doing well without recurrence for 18 months after the first operation. Intra-hepatic arterial infusion chemotherapy for liver metastasis from colorectal cancer can produce an excellent result with the use of sensitive chemotherapeutic agents.

Introduction: Percutaneous thermal segmentectomy is a single-step combination of microwave ablation, performed during arterial occlusion obtained with a balloon micro catheter, followed in the same session by balloon-occluded TACE. The aim of this multicenter retrospective study is to report the mid-term oncological performance of this technique for liver malignancies > 3.0 cm and to identify risk factors for the loss of sustained complete response.

Objectives: To demonstrate in vivo redistribution of the blood flow towards HCC's lesions by utilizing two-dimensional perfusion angiography in b-TACE procedures.
Material And Methods: In total, 30 patients with 35 HCC nodules treated in the period between January 2019 and November 2021. For each patient, a post-processing software leading to a two-dimensional perfusion angiography was applied on each angiography performed via balloon microcatheter, before and after inflation.

Background: Combined hepatocellular carcinoma and cholangiocarcinoma (CHCC-CC) is a rare subtype of primary liver malignancy and has been treated equally as intra-hepatic cholangiocarcinoma (IHCC) according to the 8th AJCC staging system. Owing to its rarity, its prognostic factors have been rarely explored and defined.
Methods: PubMed, EMBASE, the Cochrane Library and Web of Science were searched up till January 1st, 2023 and eligible studies were restricted to studies reported prognostic factors of resected CHCC-CC.

Introduction: Intrahepatic vascular shunts "IHVS" are abnormal communications between intra-hepatic vasculature involving the arterial, portal, or hepatic venous system. Arterio-portal fistula "APF" is an intrahepatic communication between the hepatic arterial system and the portal venous system without any communication with the systemic venous circulation. APF is considered a rare cause of portal hypertension and gastrointestinal bleeding in infancy.
