Insights

Surgical repair of chronic mesenteric ischemia using the distal thoracic aorta for inflow offers excellent long-term patency and survival. This antegrade bypass grafting technique demonstrates low complication rates, making it a viable primary treatment option.

Area of Science:

  • Vascular Surgery
  • Gastrointestinal Surgery
  • Surgical Outcomes

Background:

  • Chronic mesenteric ischemia (CMI) treatment traditionally uses abdominal aorta inflow for bypass grafts.
  • The distal thoracic aorta (DTA) presents a potential alternative inflow source for mesenteric revascularization.
  • Evaluating DTA inflow for CMI surgical treatment is crucial for optimizing patient outcomes.

Purpose of the Study:

  • To assess the efficacy and safety of using the distal thoracic aorta (DTA) as an inflow source for mesenteric revascularization in patients with chronic mesenteric ischemia (CMI).

Main Methods:

  • A retrospective review of patients who underwent mesenteric revascularization for CMI using DTA inflow between 1990 and 1999.
  • Utilized a thoracoretroperitoneal incision for surgical exposure and a partial occlusion clamp for maintaining distal aortic flow.
  • Grafts were placed to the celiac and/or superior mesenteric arteries.

Main Results:

  • Eighteen patients with CMI underwent DTA-inflow mesenteric bypass grafting.
  • Perioperative mortality was 6% (1 patient), with 17% experiencing major complications; no kidney failure, mesenteric infarction, or spinal cord ischemia occurred.
  • Midterm results showed 100% graft patency, 76% 5-year survival, and complete symptom resolution in all patients.

Conclusions:

  • Antegrade mesenteric revascularization utilizing DTA inflow is a safe and effective procedure for CMI.
  • This approach is associated with low morbidity, mortality, and excellent midterm graft patency and patient survival.
  • DTA inflow should be considered a primary surgical option for mesenteric revascularization in CMI patients.

The Aorta01:14

The Aorta

The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...
Thoracic Aorta01:15

Thoracic Aorta

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
Abdominal Aorta01:25

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.
