Insights

Infrapopliteal angioplasty offers high technical success and acceptable complications for critical limb ischemia. Achieving open run-off vessels improves limb salvage, though patient survival is impacted by comorbidities.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Endovascular Therapy

Background:

  • Critical chronic limb ischemia and severe claudication significantly impact patient quality of life and limb viability.
  • Infrapopliteal angioplasty is a key endovascular intervention for treating these conditions.

Purpose of the Study:

  • To assess the technical success rate of infrapopliteal angioplasty.
  • To evaluate procedure-related complications and long-term clinical outcomes, including limb salvage and patient survival.

Main Methods:

  • Retrospective analysis of 112 patients undergoing infrapopliteal angioplasty between 1997 and 1999.
  • Exclusion of patients with acute limb ischemia.
  • Prospective data collection on technical success, complications, and clinical follow-up including limb salvage and survival rates.

Main Results:

  • A technical success rate of 92% was achieved in 121 limbs.
  • The complication rate was 2.7%, with significant improvements in ankle-brachial index and walking distance.
  • One-year and three-year limb salvage rates were 83.6% and 81.1%, respectively. Survival rates were 79.4% (1 year) and 54.2% (3 years).

Conclusions:

  • Infrapopliteal angioplasty demonstrates high technical success and a manageable complication profile.
  • Favorable long-term clinical success, particularly limb salvage, is associated with achieving at least one patent run-off vessel post-procedure.
  • Patient survival is significantly influenced by the presence of comorbidities in this patient cohort.

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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

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. This...

Peripheral Artery Disease V: Postoperative Nursing Management

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
