Abstract:
Objective To investigate the characteristics of hemodynamics of proper hepatic artery and portal vein after splenectomy and devascularization. Methods The clinical data of 103 patients with portal hypertension who underwent splenectomy and devascularization in the Capital Medical University-Affiliated You'an Hospital from April 2014 to February 2019 were retrospectively analyzed. Their hemodynamics of the proper hepatic artery and portal vein were recorded before and 1 week-, and 1-, 3-, 6-, 12-, and 24-months after surgery and then statistically analyzed. Continuous data with normal distribution were compared using paired-samples t test. Results Compared with the before surgery data, the portal vein diameter, portal vein flow, maximum velocity, and average velocity of the portal vein were all significantly decreased 1-week-, 1-, 3-, 6-, 12-, and 24-months after splenectomy and devascularization (all P < 0.05). The blood flow and velocity of the proper hepatic artery was significantly increased 1 week and 1 month after surgery (all P < 0.05); however, there was no statistically significant difference at 3-, 6-, 12-, and 24-months after surgery. Conclusion The diameter, flow, and flow velocity of the portal vein after splenectomy and devascularization were significantly lower than those before surgery, whereas the proper hepatic artery flow and flow velocity were increased within 1 month after surgery and then returned back to the pre-surgery levels 3 months after surgery.
