Hepatic arterial occlusion (HAO) is frequently encountered in patients receiving hepatic arterial infusion chemotherapy (HAIC) via an implanted port-catheter system. Usually, HAO precludes continuation of HAIC, and treatment for liver metastases is changed to systemic chemotherapy. However, two cases were encountered in which, even though HAO was diagnosed by arteriography via the port, the hepatic artery was actually patent. These cases illustrate that arteriography via the port is insufficient to confirm HAO.

Hepatic Portal System01:21

Hepatic Portal System

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 responsible...

Esophageal Varices-II: Clinical Features and Management

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.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...
