A type of digestive system X-ray examination that introduces a gas into the posterior peritoneal cavity to reveal the size and morphology of the posterior peritoneal organ. A method of injecting gas into the retroperitoneal space to show the outline of the adrenal gland and kidney is a retroperitoneal angiography, also known as peri-inflammation of the kidney. It can be combined with excretory urography or retrograde urography to have certain diagnostic value for certain kidney diseases, retroperitoneal tumors, especially for adrenal diseases.

Basic Information

Specialist classification: Digestive examination classification: X-ray

Applicable gender: whether men and women apply fasting: not fasting

Tips: Take the intestinal laxative before the angiography. Fast and enema in the morning, clean and shave the anus and tail hair. Normal value

The part with high density in the human body absorbs more X-rays, and the emulsion has less light sensitivity on the film, and it is white after washing. Conversely, the low-density parts are gray or black, forming a human body image. After the gas is introduced into the peritoneal cavity, the size and shape of the posterior peritoneal organ can be displayed.

Clinical significance

Indications for adrenal gland disease, retroperitoneal non-inflammatory mass, in order to understand the changes in kidney shape, can be applied.

A method of injecting gas into the retroperitoneal space to show the outline of the adrenal gland and kidney is a retroperitoneal angiography, also known as peri-inflammation of the kidney. It can be combined with excretory urography or retrograde urography to have certain diagnostic value for certain kidney diseases, retroperitoneal tumors, especially for adrenal diseases.

Precautions

Before the test: take the intestinal laxative before the angiography. Fast and enema in the morning, clean and shave the anus and tail hair.

After the examination: it is necessary to stay in bed for 24 hours to prevent the gas from spreading up the mediastinum to the skin of the neck, causing difficulty in breathing.

Contraindications: inflammation around the kidney or retroperitoneum, postoperative retroperitoneal adhesions, infection around the anus, and severe bleeding tendency.

Inspection process

Take the chest and knee or the knee position and routinely disinfect the skin. The left index finger extends into the rectum, and the right hand holds a 20 ml empty needle containing I% procaine. The needle is placed at the waist, and the anesthetic is injected while the needle is inserted in front of the anus. Under the guidance of the left index finger, slowly push 5 cm to prevent puncture of the intestinal wall, then inject 20 ml of saline, pump without blood return, and inject oxygen or carbon dioxide.

There is resistance when injecting the first tube, and the second tube disappears later. The amount of injected gas is calculated as 15-20 ml/kg body weight. After the injection of gas, the patient has pain in the waist and abdomen. After the end of gas injection, the patient is placed on his back, in the prone position and in the sitting position for 3 minutes. The abdomen is massaged and the back is slammed to spread the gas. Immediately after the injection of gas, film.

After the examination, it is necessary to stay in bed for 24 hours to prevent the gas from spreading up the mediastinum to the skin of the neck, causing difficulty in breathing. There are few opportunities for air embolism, but a serious complication. Once it occurs, the patient takes the left lower head and makes the air sluice easy to push into the pulmonary circulation.
