Arterial Injection Pigment Contrast Test

The arterial injection pigment comparison test was carried out by the following principle. Normal pancreas or pancreatic tissue that has not lost vitality is normal, and a stain is injected into the pancreatic artery, and the pancreatic tissue in the supply area can be stained. When the pancreatic tissue is necrotic, it has lost blood supply and cannot be stained by the stain. In this test, the color of pancreatic tissue was observed by injecting methylene blue into the artery to determine whether there was vitality and to determine the extent of surgical resection. Basic Information Specialist classification: Digestive examination classification: pathological examination Applicable gender: whether men and women apply fasting: fasting Tips: Pay attention to the normal diet, pay attention to normal work and rest, and prevent endocrine disorders. Normal value Normal pancreas or pancreatic tissue that has not lost vitality is normal, and a stain is injected into the pancreatic artery, and the pancreatic tissue in the supply area can be stained. Clinical significance Abnormal results: Clinical symptoms of pancreatic tissue necrosis: 1. Symptoms of sudden upper abdominal pain or hyperthermia during the treatment of acute edematous pancreatitis, diffuse peritonitis, paralytic ileus, upper abdominal mass, gastrointestinal bleeding, neuropsychiatric symptoms, shock. 2. Signs of abdominal abdomen, tenderness and rebound tenderness, mobile dullness, bowel sounds disappeared, a small number of patients due to the bloody exudate containing pancreatic enzyme infiltrated into the subcutaneous space through the retroperitoneal space, subcutaneous fat necrosis, both sides of the abdominal wall ecchymosis Fading around the umbilicus. People who need to be examined: Pancreatitis, suspected pancreatic tissue necrosis. Precautions Forbidden before examination: pay attention to normal diet, pay attention to normal work and rest, and prevent endocrine disorders. Requirements for inspection: Actively cooperate with the doctor's request. This test is a preliminary determination method, and it is feasible to determine the pathological examination of frozen sections. Inspection process method: 1. Surgical exposure to the pancreas, if suspected pancreatic tissue necrosis, this test can be performed. 2. Suspend the intrinsic segment of the inferior border of the hepatic artery, right gastric artery and superior mesenteric artery to temporarily block blood flow. 3. Inject the 0.1% methylene blue solution (1% methylene blue 2ml plus physiological saline 18ml) 5ml-7ml into the proximal end of the spleen artery and superior mesenteric artery. 4. Observe the color change of pancreatic tissue. Results judgment and clinical significance: 1. The pancreatic tissue is in a light blue area, indicating that the blood supply is normal and can survive. It can be reserved during surgery. 2. Unstained areas suggest blood supply disorders, loss of vitality, may be considered surgical resection. Not suitable for the crowd Inappropriate crowd: The pancreas has signs of obvious necrosis. Adverse reactions and risks There are no related complications and hazards.
