Summary
Lower extremity arterial revascularization (LEAR) for critical lower limb ischemia (CLI) did not improve functional status in nonambulatory patients. These patients experienced higher adverse events and mortality, suggesting careful consideration for limb salvage attempts.
Area of Science:
- Vascular Surgery
- Critical Limb Ischemia Management
- Patient Outcomes Research
Background:
- Lower extremity arterial revascularization (LEAR) is the standard treatment for critical lower limb ischemia (CLI).
- Evaluating long-term functional status and survival post-LEAR is crucial for patient management.
- Identifying prognostic factors can optimize treatment strategies for CLI patients.
Purpose of the Study:
- To assess the long-term functional status of patients undergoing primary LEAR for CLI.
- To identify prognostic factors influencing functional status and survival after LEAR in CLI patients.
- To compare outcomes between ambulatory and nonambulatory patients undergoing LEAR.
Main Methods:
- Analysis of primary LEAR procedures, stratifying patients by preoperative functional status (ambulatory vs. nonambulatory).
- Follow-up at 3 and 6 years, categorizing adverse events (AEs) and analyzing demographic/clinical data.
- Utilizing univariate and multivariate methods to determine predictors of functional status and survival.
Main Results:
- Nonambulatory patients (Group II) were older, had more comorbidities (cardiac, renal, diabetes, hypertension), and severe CLI compared to ambulatory patients (Group I).
- Group II experienced significantly higher rates of death, minor, surgical, and systemic AEs, and unplanned reinterventions.
- Nonambulatory status, pulmonary disease, not prescribing beta-blockers, and systemic AEs were independent predictors of death; functional status did not improve in Group II.
Conclusions:
- Nonambulatory patients undergoing LEAR have substantial comorbidities and face increased risks of AEs, reinterventions, and mortality.
- LEAR did not enhance functional status in nonambulatory patients after 6 years, highlighting the need for careful consideration of limb salvage.
- Risk stratification and individualized treatment planning are essential for optimizing outcomes in CLI patients undergoing revascularization.

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...

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...

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
