まとめ

臓動脈静脈異常によって引き起こされる左側ポータル高血圧 (LSPH) はまれである. このケースは,LSPHと疑われる患者の血管異常を特定して,早期に診断と治療を行うことの重要性を強調しています.

科学分野:

血管外科血管外科
胃腸内科胃腸内科
放射線学放射線学

背景:

左側ポータル高血圧 (LSPH) は,静脈の圧力が上昇し,肝機能不全なしに胃の静脈につながる.
一般的な原因は,静脈圧縮,狭窄症,または血栓症です.
血管不形成に二次的なLSPHは極めてまれで,以前は報告されていませんでした.

研究の目的:

臓動脈静脈変形によって引き起こされたLSPHのユニークな症例を報告します.
この希少な疾患の診断の課題と管理を強調するためです.

主な方法:

53歳の男性,メレーナと胃の静脈を呈した.
診断作業には,ガストロスコピー,コントラスト強化CT,MRIが含まれており,臓動脈静脈異常が明らかになりました.
手術はを切除とハサブの手術でした.

主要な成果:

患者はメレーナを発症し,胃の静脈が確認されました.
画像検査により,動脈静脈変形が顕著な胃の静脈と付随血管で確認されました.
病理学と免疫ヒストケミストリーは,手術後の動脈静脈変形に二次的なLSPHを確認しました.

結論:

この症例は,臓動脈静脈異常形成から発生したLSPHの希少な例を表しています.
血管異常の早期差別化と非侵襲的血管検査の活用は,LSPHの疑いのある患者にとって極めて重要です.

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-I: Introduction

Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

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...

Portal Hypertension

Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
