Problems solved by technology

The current casting method used in the pathological and anatomical research of fetal heart disease is usually carried out on thoracic organs, and only the heart and great vessels are preserved. The display of internal structural abnormalities has certain limitations, especially in the analysis of the first segment of the connection between the viscera and the atrium in congenital heart disease. Real and complete 3D anatomical model

Embodiment

[0034] 3 fetuses with normal heart spontaneous abortion and 19 fetuses with spontaneous or induced congenital heart malformation were selected as casting materials, and then the following operations were performed on each casting material:

[0035] Open the chest wall to expose the heart and lungs, retain the pericardium and thymus; open the abdominal wall, place a No. 0 silk suture behind the abdominal aorta, and cut the common iliac artery on one side; separate the umbilical vein and puncture it with a 12-gauge needle of a 10ml syringe. After it is enlarged, use the scalp along the needle hole The needle hose (the front end is cut into an obtuse angle of 150-160 degrees) is punctured and placed, and the No. 0 silk thread is double-ligated and fixed; then, 500ml of normal saline or phosphate buffer solution is added with a drop of detergent to prepare the flushing solution, and the flushing solution is pumped into the syringe It is used to flush the blood vessels until the col...

Abstract

The invention provides a method for joint casting of chest and abdominal organs, which is not only easy to operate, but also retains abdominal organs. The method can facilitate the analysis of the first segment of congenital heart disease, so that the final specimen obtained by the mold can maintain the integrity, i.e., the integrity is good and the structure is real and fine, and a true 3D anatomical model for clinical and educational practice is provided. The three-dimensional display of the normal fetal heart and complex congenital heart disease specimens can help to observe the structure of the heart chamber and to also observe the origin, movement, spatial relationship and branch changes of the thoracic and abdominal vessels, thus providing valuable information for identifying and understanding the normal or pathological morphology of blood vessels.

Description

【Technical field】 [0001] The invention relates to a method for casting a fetal organ specimen, in particular to a method for combined casting of thoracoabdominal organs. 【Background technique】 [0002] Cardiac anatomy is a well-established approach to recognizing cardiac abnormalities and is an essential part of the learning experience in this field. The formation of casts of the cardiovascular system has been described since the sixteenth century, and Cook et al. used silastic models to assess the interpretation of fetal heart anatomy and found that it correlated strongly with echocardiographic and anatomical features. Vascular corrosion casting is a classic technique for displaying the three-dimensional anatomy of the cardiovascular system. [0003] The cast can successfully display the real anatomical structure and spatial course of the fetal normal heart and cardiac and great vessel malformation, which is helpful for teaching and clinical research, especially for helpin...
