Preoperative Portal Vein Embolization Tailored to Prepare the Liver for Complex Resections: Initial Experience
- Institut Gustave Roussy, Department of Radiology (France)
The purpose of this study was to evaluate the safety and efficacy of preoperative portal vein embolization (PVE) tailored to prepare the liver for complex and extended resections. During the past 5 years, 12 PVEs were performed in noncirrhotic patients with liver metastases from colon cancer (n = 10), choroidal melanoma (n = 1), and leiomyosarcoma (n = 1) to prepare complex anatomical liver resections in patients with small future remnant livers. These liver resections planned to preserve only segment IV in four patients, segments IV, V, and VIII in four patients, segments II, III, VI, and VII in three patients, and segments V and VI in one patient. PVE was performed under general anesthesia with a flow-guided injection of a mixture of cyanoacrylate and Lipiodol using a 5-Fr catheter. All portal branches feeding the liver segments to be resected were successfully embolized with cyanoacrylate except one, which was occluded with coils due to the risk of reflux with cyanoacrylate. After a mean of 32 days, CT volumetry revealed a mean hypertrophy of the unembolized liver of 47 {+-} 25% (range, 21-88%). Liver resections could be performed in 10 patients but were canceled in 2, due to the occurrence of a new hepatic tumor in one and an insufficiently increased volume in the other. Among the 10 patients who underwent the liver resection, 1 died of postoperative sepsis, 3 died 3 to 32 months after surgery, including 1 death unrelated to cancer, and 6 were alive after 6 to 36 months after surgery. In conclusion, in this preliminary report, PVE appears to be feasible and able to induce hypertrophy of the future remnant liver before a complex and extended hepatectomy. Further evaluation is needed in a larger cohort.
