文摘

Portal vein thrombosis (PVT) after hepatectomy is rare; however, it increases mortality and morbidity. Few studies have been conducted that focused on PVT following major hepatectomy.

Methods

Patients who underwent hepatectomy at a single institution were retrospectively reviewed, and risk factors and management options were evaluated.

Results

Of the 1,193 patients undergoing hepatectomy, 25 patients developed PVT. Right-sided hepatectomy, caudate lobectomy, splenectomy, and postoperative bile leakage were independent risk factors for PVT following hepatectomy. PVT occurred more frequently after major hepatectomy compared with minor hepatectomy. Increased instability and reduced portal venous flow caused by kinking was the reason for increasing the risk of PVT after right-sided hepatectomy with caudate lobectomy. The new operative procedure, suturing the posterior wall of the portal vein with the anterior wall of the inferior vena cava, was effective for reducing the risk of PVT following right-sided hepatectomy. Operative thrombectomy showed significant benefits for PVT detected within 5 days after hepatectomy.

Conclusions

PVT frequently occurs following major hepatectomy. Urgent operative thrombectomy is strongly recommended for PVT with early detection.
