| Popis: | Liver venous deprivation (LVD) is an emerging, minimally invasive strategy to induce rapid liver hypertrophy of the future liver remnant (FLR) before a major hepatectomy. LVD (aka “double vein embolization”) entails same-session percutaneous embolization of the portal and hepatic veins of the planned liver resection. This report discusses LVD’s utilization and technical challenges in managing a 49-year-old male with recurrent multifocal colorectal liver metastases (CRLM). The patient initially underwent neoadjuvant FOLFOX chemotherapy followed by a simultaneous laparoscopic sigmoid colectomy and liver surgery (microwave ablation of segment V and wedge resections of segment one and IVb), followed by completion of chemotherapy. The patient had an R0 resection with clear colon and liver surgical margins. Nine months after the initial surgery, the patient had a rise in tumor markers, and surveillance imaging demonstrated recurrence of liver metastases in segments I and V. LVD was performed by interventional radiology, which led to a 28% increase in FLR (segments II, III, and IV); initially measuring 464 cm3 before LVD and measuring 594 cm3 on post-procedure day 21. The patient underwent right hemi-hepatectomy and caudate resection on post-procedure day 29. The patient did not have any complications and was discharged on postoperative day 6. The patient remains disease-free with no evidence of recurrence at 12 months follow-up. |
