まとめ
尾皮の右辺と右の肝臓の区別は 極めて重要ですが 難しいことです この研究では,肝臓の鋳型を用いて,パラカヴァル部分とセグメント8の間のジグザグの境界平面を特定し,独特の静脈パターンで定義した.
科学分野:
- アナトミー
- 手術 アナトミー
- 肝臓の解剖学
背景:
- 手術の計画と実行には肝臓の解剖学的境界の正確な識別が不可欠です.
- 尾関節と右肝臓の境界は 特にセグメント8は 重要な解剖学的課題です
- 血管構造を理解することは肝臓の境界を定義する鍵です
研究 の 目的:
- 右の肝臓のセグメント8に対する尾状葉のパラカヴァル部分の右辺を正確に定義する.
- 解剖学的および血管学的特徴を明らかにするために この挑戦的な境界線を描画します.
- 肝臓の手術のナビゲーションの改善のための解剖学的洞察を提供するために.
主な方法:
- エポキシ樹脂とカラー染料から作成された肝臓の鋳型の解剖.
- 静脈筋と排水パターンの詳細な検査
- パラカヴァル部分とセグメントの血管接続の比較分析 8.
主要な成果:
- 肝臓の右辺には 状の2つの大きな静脈が 下腔静脈と中枢静脈に流れ込み 短い肝臓静脈を形成しています
- 右肝静脈と下腔静脈に繋がっている 静脈.
- これらの独特の静脈パターンはジグザグの境界線を形成し,尾状葉と右の肝臓の分割と相関しています.
- PCとセグメント8の間の直線静脈の枝は観察されなかった.
結論:
- 血管の解剖学,特に静脈の配置は,尾皮のパラカヴァ部分とセグメント8の境界を明確に定義しています.
- この発見は 肝臓の領域を 区別するための 信頼性の高い 解剖学的基準を提示しています
- 直径の長い静脈の接続がないことは,この境界の独特な性質を補強する.

01:17Gross Anatomy of the Liver
863
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.

01:21Hepatic Portal System
2.1K
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...

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

01:19Abdominal Regions and Quadrants
12.0K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...
