Primary segmental omental infarction

Introduction to primary segmental infarction Idiopathic Segmental Infarction is rare. The occurrence of infarction is not related to trauma, torsion, cardiovascular disease, adhesion or other intra-abdominal pathology. It is an unexplained retinal acute vascular disease and spontaneous. The name of the omental infarction or the omental hemorrhagic infarction. basic knowledge The proportion of illness: 0.0005% Susceptible population: common in 20 to 30 years old well-nourished men Mode of infection: non-infectious Complications: retinitis tuberculous peritonitis acute appendicitis acute cholecystitis acute pelvic inflammatory disease

Omental primary segmental infarction

Many scholars use different theories to explain the pathogenesis of the disease, generally considered: venous engorgement or abnormal venous return, heavy omentum to make the blood vessels elongated or / and endometrial epithelial damage, mild trauma or increased abdominal pressure and omental anatomy Mutations can lead to retinal thrombosis. The infarct is usually the free edge of the right omentum. The lesions are triangular, most of which are about 6-8 cm in diameter, sometimes extending to the surrounding tissue and parietal peritoneum. Omental arteriovenous thrombosis and infiltration of multinucleated cells and round cells.

Omental primary segmental infarction prevention

Early detection and early treatment, the disease has a good prognosis. If the patient has abdominal pain, the right lower quadrant has signs of peritoneal irritation such as tenderness and muscle tension, and the increase in the number of peripheral white blood cell membranes, in addition to attention to appendicitis, cholecystitis, and female attachment diseases, it is necessary to pay attention to the primary omentum. The possibility of sexual segmental infarction, as well as early examination and active treatment are still necessary.

Retinal primary segmental infarction complications Complications, retinitis, tuberculous peritonitis, acute appendicitis, acute cholecystitis, acute pelvic inflammatory disease

Can be complicated by retinal inflammation.

The majority of Omentits are caused by various inflammations in the abdominal cavity. Common causes such as tuberculous peritonitis, acute appendicitis, acute cholecystitis, acute pelvic inflammatory disease, diverticulitis, and various types of peritonitis can cause the omentum. Inflammation, in severe cases, can form adhesions later, this acute inflammation generally fades with the healing of the primary lesion. In addition, there are unspecific anabolic leukoganitis of unknown cause, also known as non-specific panniculitis.

Omentum primary segmental infarction symptoms Common symptoms Lower abdominal pain Peritoneal irritation Ascites nausea Abdominal pain Bloody ascites Sensation Acute abdomen tension

Due to abdominal pain in the patient, peritoneal irritation such as tenderness and muscle tension in the right lower quadrant, and increased white blood cell membrane count, often misdiagnosed as acute appendicitis, or even acute cholecystitis, B-mode ultrasound can find a small amount of ascites, abdominal wear may be extracted Bloody ascites, often diagnosed because of acute abdomen laparotomy, many patients with this disease were misdiagnosed as acute appendicitis, only in the operation of the abdominal cavity with bloody serous exudate, only to notice that the infarct area can form A hard, red or purple-black lump.

Commonly found in men who are well-nourished between the ages of 20 and 30, men are 2.5 times more likely to be women than women. The patient is characterized by persistent severe right abdominal pain, which accounts for about 3/4 of the right lower abdominal pain. Often have nausea and vomiting, may have fever, check abdominal localized tenderness, ruminant pain and muscle tension, tenderness often in the right lower abdomen and around the point, can touch the abdominal mass or partial full, skin hypersensitivity is unique to this disease Signs, white blood cells are normal or slightly elevated.

Examination of primary segmental infarction

Blood routine, abdominal plain film, abdominal CT, abdominal vascular ultrasound, abdominal shape palpation, abdominal percussion.

Diagnosis and diagnosis of primary segmental infarction

It can be diagnosed based on medical history, clinical symptoms and laboratory tests.

Identification with acute appendicitis, acute cholecystitis and other diseases.
