Peripheral Artery Disease III: Interprofessional Care01:27

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 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.

Area of Science:

  • Gastroenterology
  • Surgical Procedures
  • Vascular Surgery

Background:

  • Hemorrhoids affect a significant portion of the population.
  • Various surgical interventions exist for hemorrhoid treatment.
  • Transanal hemorrhoidal dearterialization (THD) offers a minimally invasive approach.

Purpose of the Study:

  • To systematically review evidence on transanal hemorrhoidal dearterialization (THD).
  • To assess the safety and efficacy of THD.
  • To define indications and limitations of THD.

Main Methods:

  • Systematic review of published studies on THD.
  • Inclusion of studies regardless of language.
  • Primary outcomes: postoperative pain and hemorrhoid recurrence.

Main Results:

  • Seventeen articles with 1,996 patients analyzed; study quality generally low.
  • Low complication rates: 18.5% postoperative pain, 3 significant hemorrhages.
  • Recurrence rates at one year: 10.8% (prolapse), 9.7% (bleeding), 8.7% (pain); higher for grade IV hemorrhoids.

Conclusions:

  • THD shows promise for second and third-degree hemorrhoids.
  • Further clinical trials and comparative studies are necessary.
  • Longer follow-up is needed to establish THD's role in hemorrhoid treatment.
