Insights

Endovascular therapy for chronic limb ischemia shows high wound healing and amputation-free rates. This minimally invasive approach offers a viable alternative to open surgery for distal arterial disease.

Area of Science:

  • Vascular Surgery
  • Endovascular Interventions
  • Peripheral Arterial Disease

Background:

  • Chronic limb ischemia (CLI) is associated with significant limb loss and mortality.
  • Open surgery is the standard treatment for distal CLI.
  • Endovascular surgery offers a less invasive alternative with comparable outcomes.

Purpose of the Study:

  • To evaluate the outcomes of endovascular treatment for distal arterial disease.
  • To report on a cohort of patients treated at our institution.

Main Methods:

  • Retrospective review of endovascular procedures for distal lower extremity disease (2016-2019).
  • Analysis of patient demographics, comorbidities, presentation, interventions, complications, and outcomes.
  • Primary outcomes: wound healing, reintervention, freedom from major amputation.

Main Results:

  • 48 limbs in 41 patients (mean age 75) treated; 73% presented with major wounds.
  • 85% wound healing and 90% freedom from amputation at one year.
  • 18% complication rate, 2% perioperative mortality, 76% one-year survival.

Conclusions:

  • Endovascular therapy is effective for CLI, achieving high rates of wound healing and limb salvage.
  • The procedure demonstrates low perioperative mortality and manageable complication rates.
  • This approach is a valuable option for patients with distal arterial disease.

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 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...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Peripheral Artery Disease IV: Nursing Management

 The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses,...

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...
