Title: Value of 16-slice CT Angiography in Preoperative Assessment of Vascular Anatomy of Stomach Before Laparoscopy-assisted Gastrectomy
Abstract: Objective To evaluate the value of CT angiography(CTA) in the preoperative assessment of the vascular anatomy of the stomach before laparoscopy assisted gastrectomy.Materials and Methods 24 consecutive patients for laparoscopy assisted gastrectomy underwent dual phase enhancement scanning on MSCT.Three-dimensional CT angiography was reconstructed using volume rendering technique based on arterial phase images and venous phase images.Resu-lts Three-dimensional CTA showed the left gastric artery in 24 cases,right gastric artery in 23 cases,left gastric vein in 24 cases,and alternative left hepatic artery in 6 cases.Both the sensitivity and positive predictive value of displaying the left gastric artery,left gastric vein,and alternative left hepatic artery were 100%.The sensitivity and positive predictive value of displaying the right gastric artery was 100% and 96%,respectively.Conclusion Three-dimensional CTA using MSCT could clearly reveal vascular anatomy of the stomach,which might play an important role in facilitating the laparoscopy assisted gastrectomy procedure.
