The angiosome concept

Area of Science:

  • Vascular Surgery
  • Anatomy
  • Ischemic Limb Disease

Background:

  • Chronic limb-threatening ischemia (CLTI) affects wound healing and amputation rates.
  • Angiosome-guided endovascular treatment shows promise for CLTI.
  • The role of angiosome concept in bypass surgery for ischemic foot is unclear.

Purpose of the Study:

  • To review foot and ankle arterial anatomy and circulation.
  • To discuss the availability and limitations of angiosome-guided bypass surgery for CLTI.

Main Methods:

  • Review of arterial anatomy of the foot and ankle.
  • Discussion of supplementary circulation, including arterial-arterial connections and choke nexus.
  • Consideration of patient factors like diabetes and renal dysfunction impacting circulation.

Main Results:

  • Multiple supplementary circulations exist in the foot and ankle.
  • The angiosome concept may have limited importance in bypass surgery for CLTI due to collateral circulation.
  • Impaired supplementary circulation in CLTI patients with diabetes or renal dysfunction is noted.

Conclusions:

  • Angiosome-guided bypass surgery for CLTI has limitations due to complex foot and ankle arterial anatomy.
  • The effectiveness of the angiosome concept in bypass surgery for ischemic foot requires further elucidation, especially in specific patient populations.

Anastomoses01:19

Anastomoses

In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.

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.
