Background:
The lethality of acute mesenteric ischemia (AMI) remains quite high with 50-70%. The main reasons for that are the fact that AMI is rarely taken into consideration by the differential diagnosis of acute abdomen, the time-consuming diagnostic process, and the lack of a standardized therapeutic concept. The present interdisciplinary review aims to increase awareness among physicians and to help improve clinical outcomes.
Methods:
This clinical therapeutic review is based on author expertise as well as a selective literature survey in PubMed based on the term 'mesenteric ischemia', combined with the terms 'arterial', 'clinical presentation', 'diagnosis', 'therapy', 'surgery', and 'interventional radiology'. Based on these search results as well as on the guidelines of the German Society of Vascular Surgery, the American College of Cardiology, and the American Heart Association, we present an interdisciplinary treatment concept.
Results:
AMI is a vascular emergency that can be successfully treated only within the first hours after the onset of symptoms. Computed tomography angiography is the diagnostic method of choice. Intensive care unit treatment can prevent the occurrence of multiple organ failure. Treatment primarily consists of the revascularization of the mesenteric arteries. Endovascular techniques should be given priority, whereas signs of peritonitis or a central arterial occlusion with high thrombus load primarily require a surgical approach in order to save time and increase patient safety. Additional bowel resections can play a significant role in the treatment of intestinal sepsis.
Conclusion:
Prompt and goal-oriented diagnosis and consistent treatment of AMI within 4-6 h from the onset of symptoms can be decisive for the reduction of AMI-associated lethality. In order for this to happen, a standardized concept of emergency treatment needs to be implemented.
Insights
Acute mesenteric ischemia (AMI) has high mortality. Prompt diagnosis and treatment within 4-6 hours, prioritizing endovascular revascularization, can significantly reduce death rates.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Emergency Medicine
Background:
- Acute mesenteric ischemia (AMI) presents a high mortality rate (50-70%).
- Delayed diagnosis, lack of standardized treatment, and infrequent consideration in acute abdomen differential diagnoses contribute to poor outcomes.
- This review aims to enhance physician awareness and improve clinical outcomes for AMI.
Purpose of the Study:
- To present an interdisciplinary treatment concept for acute mesenteric ischemia.
- To increase physician awareness and improve clinical outcomes for AMI.
- To provide guidance on diagnosis and therapy for AMI.
Main Methods:
- An interdisciplinary review based on author expertise.
- Selective literature survey in PubMed using terms like 'mesenteric ischemia', 'arterial', 'diagnosis', 'therapy', 'surgery', and 'interventional radiology'.
- Incorporation of guidelines from the German Society of Vascular Surgery, American College of Cardiology, and American Heart Association.
Main Results:
- Computed tomography angiography is the preferred diagnostic method for AMI.
- Early treatment within hours of symptom onset is critical for successful outcomes.
- Revascularization of mesenteric arteries is the primary treatment; endovascular techniques are preferred, but surgery is indicated for peritonitis or extensive thrombosis.
Conclusions:
- Prompt, goal-oriented diagnosis and treatment within 4-6 hours are crucial for reducing AMI-related mortality.
- Implementation of a standardized emergency treatment concept is necessary.
- Intensive care unit management is vital to prevent multiple organ failure.

Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
