Multi-slice spiral CT of living-related liver transplantation in children: pictorial essay.

Choi SH, Goo HW, Yoon CH - Korean J Radiol (2004 Jul-Sep)

Bottom Line: Multiplanar and three-dimensional imaging using multi-slice spiral CT can be used for preoperative vascular imaging, as well as for evaluating postoperative complications.In this essay, we describe the usefulness of multi-slice CT, combined with a variety of different reconstruction techniques, for the preoperative evaluation of transplant recipients.In addition, we demonstrate the multi-slice CT findings of postoperative complications, including vascular stenosis or thrombosis, bile duct leak or stricture, and extrahepatic fluid collection.

ABSTRACT
In pediatric living-related liver transplantation, preoperative evaluation of the recipient is important for surgical planning, while the accurate diagnosis of postoperative complications is essential for graft salvage. Multiplanar and three-dimensional imaging using multi-slice spiral CT can be used for preoperative vascular imaging, as well as for evaluating postoperative complications. In this essay, we describe the usefulness of multi-slice CT, combined with a variety of different reconstruction techniques, for the preoperative evaluation of transplant recipients. In addition, we demonstrate the multi-slice CT findings of postoperative complications, including vascular stenosis or thrombosis, bile duct leak or stricture, and extrahepatic fluid collection.

Hemorrhoidal vein in a 6-month-old girl. Volume rendering image well delineates its continuation with the inferior mesenteric vein (arrowheads). Diffuse narrowing of the portal vein (arrows) is noted. RGV = right gastric vein, LGV = left gastric vein, SV = splenic vein, PEV = paraesophageal vein, SMV = superior mesenteric vein, IVC = inferior vena cava

Figure 11: Hemorrhoidal vein in a 6-month-old girl. Volume rendering image well delineates its continuation with the inferior mesenteric vein (arrowheads). Diffuse narrowing of the portal vein (arrows) is noted. RGV = right gastric vein, LGV = left gastric vein, SV = splenic vein, PEV = paraesophageal vein, SMV = superior mesenteric vein, IVC = inferior vena cava

Mentions: Spontaneous portosystemic varices are commonly found in cirrhotic patients and may have detrimental effects on graft perfusion. Based on the preoperative evaluation, varices can either be ligated during surgery or embolized to increase graft perfusion and to reduce the risk of intraoperative bleeding (7). Multi-slice CT can accurately demonstrate the size and distribution of varices (Figs. 8-11).
