What is the Difference Between Mediastinum and Pericardial Cavity

The纵隔和心包腔之间的关键区别是纵隔是位于两个胸膜囊之间的胸腔腔的中心隔室，而心包腔是心脏浆膜心包的两层形成的空间。

The thoracic cavity is the hollow space surrounded by the rib cage anddiaphragm. It contains three compartments: two pleural cavities and a mediastinum. The mediastinum is divided into superior mediastinum and inferior mediastinum. The latter is further subdivided into anterior, middle, and posterior. The middle mediastinum contains the heart covered by thepericardium. The serous pericardium contains the pericardium cavity, which facilitates the free movement of the heart. Therefore, the mediastinum and pericardial cavity are two compartments that protecting organs in the human body.

What is Mediastinum?

The mediastinum is the central compartment of the thoracic cavity that is surrounded by loose connective tissues. It is also known as themediastinal cavity. It contains the heart and its vessels,oesophagus, trachea，胸管，phrenic和迷走神经，百里香和淋巴结。它充当了在前往腹部途中穿越胸腔的结构的管道。上纵隔和下纵隔为两个部分。上纵隔向上延伸并在上胸腔孔径上终止。下纵隔向下延伸并在隔膜处终止。下纵隔可以进一步细分为前，中部和后部。在纵隔中分布着几组淋巴结。通常，纵隔中的大多数器官将其排入胸腔管道。

Mediastinal diseases are medical conditions arising from the tissues in this cavity. These conditions include cancerous tumors like thymoma, lymphoma, germ cell tumors, carcinoids and non-cancerous tumors (lipoma and teratoma), enlarged lymph nodes, masses, and cysts. Thoracic surgeons perform medical procedures (invasive and non-invasive) to treat mediastinal diseases. Furthermore, most modern procedures can be performed minimally invasively or robotically to treat conditions involving mediastinum.

什么是心包腔?

心包腔是心脏浆膜心包的两层之间的空间。它通常包含少量的浆液液。这种浆液液会降低表面张力并充当润滑。因此，心包腔促进了心脏的自由运动。心包腔围绕着心脏围绕着心脏，除了进入大船的进入点和出口。心包层在大容器周围制造了两个不同的管子。通过腔体的这些管子和血管的这些管的处置形成了倾斜和横向窦。

Pericardial effusion is a medical condition resulting due to excessive fluid in the pericardial cavity. This medical condition can lead to cardiac tamponade. Pericardiocentesis is a procedure used to remove fluid in the pericardial cavity.

What are the Similarities Between Mediastinum and Pericardial Cavity?

• 纵隔和心包腔是保护人体器官的两个空腔。
• Both cavities enclose important organs.
• 两种空腔的变化都会引起疾病。
• The diseases associated with these cavities are treatable.

纵隔和心包腔之间有什么区别？

A mediastinum is the central compartment of the thoracic cavity located between the two pleural sacs, while the pericardial cavity is the space formed between the two layers of the serous pericardium of the heart. So, this is the key difference between mediastinum and pericardial cavity. Furthermore, the mediastinum encloses the heart and its vessels, oesophagus, trachea, thoracic ducts, phrenic and vagus nerves, thymes, and lymph nodes. On the other hand, the pericardial cavity encloses only the heart.

The below infographic lists the differences between mediastinum and pericardial cavity in tabular form for side by side comparison.

摘要 - 纵隔vs心包腔

The mediastinum and the pericardial cavity are two compartments that function to protect vital organs in the human body. The mediastinum is the central compartment of the thoracic cavity. It is located between the two pleural sacs. Whereas, the pericardial cavity is the space formed between the two layers of the serous pericardium of the heart. Thus, this summarizes the difference between mediastinum and pericardial cavity.
