Mesenteric artery ischemia is a critical condition associated with insufficient blood supply to the abdominal organs due to obstruction or narrowing of the mesenteric arteries, which supply blood to the small and large intestines. This can lead to intestinal wall necrosis, peritonitis, and other serious consequences. The main causes of ischemia are atherosclerosis, thrombus formation, and embolism. Symptoms of the disease can vary from mild abdominal pain to acute abdominal cryptis, which makes this disease dangerous and requires timely diagnosis and treatment.
History of the disease and interesting historical facts
The history of mesenteric artery ischemia research spans several centuries. The first mentions of such conditions date back to the 17th century, when anatomists began to focus on the role of vessels in pathology. At the end of the 19th century, various forms of intestinal ischemia were described in the work of the German pathologist Strongel. In the 20th century, with the development of angiography and modern imaging methods, it became possible to study this pathology in more detail. One of the most important studies was the work conducted in the 1940s, which laid the foundations for surgical treatment and emphasized the importance of early diagnosis. Interestingly, until the beginning of the 21st century, mesenteric artery ischemia remained a relatively rare condition, whereas with the increase in cardiovascular diseases, it began to be diagnosed more often.
Epidemiology
The epidemiology of mesenteric artery ischemia is characterized by a constant increase in incidence in recent decades. According to various studies, the percentage of patients hospitalized with a diagnosis of intestinal ischemia ranges from 1.5 to 5.3% of the total number of patient visits for abdominal pain. Basically, ischemia is observed in people over 60 years of age, which is associated with the progression of atherosclerosis. Men are susceptible to this disease 1.5-2 times more often than women. According to statistics, mortality in acute conditions ranges from 40 to 70%, depending on the timeliness of medical care.
Genetic predisposition to this disease
To date, studies have shown that genetic predisposition to mesenteric artery ischemia has been ignored in most epidemiological studies. However, some mutations in genes involved in lipid metabolism may play a significant role in the development of atherosclerosis and, as a consequence, lead to ischemia. In particular, the APOE gene, involved in cholesterol metabolism, may be associated with an increased risk of cardiovascular disease. Also, hereditary thrombophilias, such as factor V Leiden mutation and protein C and S gene mutations, may promote thrombus formation, which is one of the key factors in mesenteric artery ischemia.
Risk factors for the development of this disease
Risk factors for mesenteric artery ischemia are divided into modifiable and non-modifiable.
- Modifiable factors:
- Smoking
- Hypertension
- Dyslipidemia
- Diabetes mellitus
- Obesity
- Poor diet (high saturated fat)
- Non-modifiable factors:
- Age (over 60 years)
- Gender (men are more susceptible)
- Heredity (predisposition to cardiovascular diseases)
Diagnosis of this disease
Diagnosis of mesenteric artery ischemia requires a comprehensive approach that includes both clinical and instrumental methods. The main symptoms of the disease are often nonspecific and include:
- Sharp or cramping pain in the abdomen, especially after eating;
- Nausea and vomiting;
- Change in stool (diarrhea or constipation);
- General deterioration of condition.
To confirm the diagnosis, the following is carried out:
- Laboratory tests:
- Complete blood count (leukocytosis, anemia);
- Biochemistry (increased lactate levels).
- Radiological examinations:
- Ultrasound examination (US) of the abdomen;
- Computed tomography (CT) with contrast;
- Angiography of the mesenteric arteries.
- Other types of disease diagnostics:
- Magnetic resonance angiography;
- Endoscopic examinations;
- Laparoscopy in complex cases for diagnosis.
- Differential diagnosis:
- Pancreatitis;
- Gallbladder problems;
- Infection and inflammatory bowel disease.
Treatment
Treatment for mesenteric artery ischemia varies and depends on the severity of the condition. The main treatment methods include:
- General treatment:
- Elimination of risk factors (maintaining a healthy lifestyle, quitting smoking);
- Low-fat, high-fiber diet.
- Pharmacological treatment:
- Anticoagulants (eg, heparin to prevent blood clots);
- Aspirin to improve blood circulation;
- Vascular drugs for vasodilation.
- Surgical treatment:
- Embolectomy or thrombectomy;
- Mesenteric artery bypass;
- Resection of necrotic areas of the intestine if necessary.
- Other types of treatment:
- Elimination of concomitant diseases (for example, treatment of diabetes).
List of medications used to treat this disease
The main drugs used to treat mesenteric artery ischemia include:
- Heparin;
- Aspirin;
- Clopidogrel;
- Cholesterol-lowering drugs (atorvastatin, simvastatin);
- Agents for improving microcirculation (meldonium, trental).
Disease monitoring
Monitoring of patients with mesenteric artery ischemia is vital. Control steps include:
- Regular ultrasound and CT scans to monitor the condition of the vessels;
- Laboratory tests for lactate levels and ischemic markers;
- A visit to the doctor according to the established schedule to monitor the condition and adjust treatment.
The prognosis of the disease may vary from favorable to unfavorable depending on the clinical situation and the speed of treatment. Possible complications include intestinal necrosis, peritonitis, and the development of sepsis.
Age-related features of the disease
The course of mesenteric artery ischemia critically depends on the age group:
- Babies and children: Cases of ischemia are rare and are often associated with vascular malformations or infections.
- Adults: Most susceptible are patients over 60 years of age with concomitant cardiovascular diseases.
- Elderly people: The risk is significantly increased by atherosclerosis and the presence of multiple comorbid conditions.
