[DYNAMICS OF HEPATIC BLOOD FLOW IN IMMEDIATE PERIOD AFTER PREOPERATIVE EMBOLIZATION OF A PORTAL VEIN]

|March 8, 2016
Summary
Embolization of the right portal vein branch (ERB PV) significantly increases blood flow in the left portal vein, promoting liver regeneration. This compensatory mechanism aids in preparing the remaining liver for major hepatic resection.
Area of Science:
- Hepatology
- Vascular Surgery
- Radiology
Context:
- Analysis of intrahepatic hemodynamics following portal vein embolization.
- Study population: 42 patients undergoing major hepatic resection for focal hepatic diseases.
- Focus on changes post-embolization of the right branch of the portal vein (ERB PV).
Purpose:
- To analyze the hemodynamic changes in intrahepatic blood flow after ERB PV.
- To evaluate the impact of ERB PV on portal vein and hepatic artery blood flow.
- To assess the relationship between blood flow changes and liver regeneration.
Summary:
- Following ERB PV, blood flow in the left portal vein increased by 226% on day 3, reaching 337% of baseline.
- Right hepatic artery (HA) blood flow increased by 282% on day 3 post-ERB PV, with subsequent non-significant reduction.
- Left HA blood flow remained largely unchanged; left hepatic lobe volume increased due to enhanced blood flow, aiding regeneration.
Impact:
- Demonstrates compensatory hyperperfusion in the contralateral lobe after PV embolization.
- Highlights the role of altered hemodynamics in promoting liver regeneration prior to resection.
- Provides insights into managing patients requiring major hepatic resection with planned portal vein embolization.

747
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

01:26Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
333
Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...
