Parasternal Line

The parasternal line (parasternal) is an anatomical structure that runs through the chest and is a continuation of the costal arch. It starts from the xiphoid process and runs along the anterior surface of the chest to the level of the sixth rib. The parasternal line is an important landmark for surgical operations, especially in the heart and lungs.

The parasternal line has several important functions in the human body. Firstly, it serves to attach the muscles and fascia of the chest. Secondly, the parasternal line allows surgical manipulation of the heart and lungs, as it is a safe and easily accessible point for making incisions. Thirdly, the parasternal line is also used to install catheters in the heart and lungs, which allows for the diagnosis and treatment of diseases of the cardiovascular system.

It is important to note that the parasternal line can be used to diagnose various diseases, such as pneumonia, pleurisy, pericarditis and others. When performing a chest x-ray, parasternal lines can be used to determine the location and extent of pathological changes in the lungs and heart.

In general, the parasternal line plays an important role in medical practice and can be used for both diagnosis and treatment of various diseases. Its knowledge and use can help improve the quality of medical care and reduce risks for patients.

The parasternal direction is considered to be the right direction of the chest, that is, located on the right side of the median plane. The left xiphoid foramen fused with it is located to the left of this line. For example, doctors can use this position to perform a puncture of the pleural cavity. Also, using this line, you can determine the position of the heart, lungs and phrenic nerve. It goes between the sternum and the longus pectoralis muscle. However, to avoid chest injury, it is not recommended to pierce this line.
