Understanding and managing reduced blood supply to the intestine. Early diagnosis and treatment are vital for protecting the patient's life.
Arterial Supply
How do arteries work in intestinal ischemia?
The arterial supply to the intestine is rich with multiple anastomoses that function as safety valves, activating when the main blood supply networks fail or are insufficient. The superior mesenteric artery and the celiac artery are the two main branches bearing the burden of intestinal blood supply.
Rich Anastomoses
Multiple safety networks activate when main vessels fail
Safety Valves
Collateral networks compensate for the deficit when stenosis develops
Thrombi in intestinal arteries
Types of Ischemia
Intestinal Ischemia
As in the lower limbs, the slower the development of stenosis (atherosclerotic plaque), the more time collateral networks (small arterial branches) have to compensate for the deficit.
Acute Intestinal Ischemia
The superior mesenteric artery is suddenly occluded. Severe abdominal pain appears which, if not treated within hours, progresses to a life-threatening condition as irreversible damage develops in the small intestine.
Requires immediate intervention — emergency endovascular or surgical revascularization
Chronic Intestinal Ischemia
Stenoses and reduced blood supply develop gradually. The patient experiences pain after meals, when large amounts of blood are needed in the intestine for digestion. In advanced stages, they are forced to induce vomiting for relief, avoid meals, and continuously lose weight.
Gradual progression — planned minimally invasive treatment
Therapeutic Options
Specialized Treatment for Intestinal Ischemia at Vascular Therapy
In the majority of cases, acute intestinal ischemia requires emergency endovascular or surgical revascularization, while chronic intestinal ischemia is more likely to be manageable with planned minimally invasive methods (endovascular with angioplasty / Stenting).
Acute Ischemia
Emergency endovascular or surgical revascularization for immediate restoration of blood flow to the intestine and avoidance of irreversible damage.
Chronic Ischemia
Planned angioplasty and Stenting: minimally invasive methods to restore arterial flow without open surgery.
Endovascular angioplasty and Stenting
