Application of Color Doppler Ultrasound in the Treatment of Vascular Diseases Around the Cardia

Abstract

Objective: This paper uses color Doppler ultrasound technology to study the hemodynamic characteristics of portal hypertension and splenectomy plus pericardial vascular disruption, to understand the pathogenesis of portal hypertension, and to understand the spleen. The effects of resection and pericardial vascular dissection on portal vein and hepatic artery hemodynamics were analyzed. Methods: Nine male in our hospital’s hepatobiliary surgery from January 2017 to December 2018 were selected. The preoperative upper gastrointestinal barium meal or gastroscopy confirmed that all patients had moderate to severe esophageal and gastric fundus. The surgical method was splenectomy and pericardial vascular disconnection. Color Doppler ultrasound was performed on portal vein and hepatic arterial hemodynamics to observe the presence or absence of portal vein thrombosis. Result: Preoperative hemodynamic status of the case group: the diameter of the hepatic artery was (0.34±0.01) cm, the value is 0.34 cm; the maximum flow velocity of the hepatic artery was (64.6±5.0) cm/s, the value of 64.7 cm/s; The postoperative hemodynamic status of the case group: the diameter of the hepatic artery was (0.41±0.02) cm, the value of 0.41 cm; the maximum flow velocity of the hepatic artery was (88.5±6.1) cm/s, the value of 89.6 cm/s. Conclusion: Color Doppler ultrasound has obvious application value in the treatment of pericardial vascular diseases. 1 splenectomy and pericardial vascular disconnection can increase the flow of hepatic artery, and reduce the total blood flow into the liver after surgery. The proportion of hepatic arterial blood flow increased, and the oxygen supply to increase.
