Deep Venous Arterialization for Critical Limb Threatening Ischemia
Introduction to DVA
- The European Society of Cardiology recommends revascularization as soon as possible in patients with critical limb threatening ischemia (CLTI) (Class I, Level B recommendation) 1, 2, 3
- Early recognition and referral to a vascular team for limb salvage is a Class I recommendation 1, 2, 3
Rationale for DVA
- The American College of Cardiology and American Heart Association guidelines state that patients with cardiac ischemia, cardiomyopathy, congestive heart failure, severe lung disease, or renal failure are at greater risk for adverse perioperative events, and initial percutaneous revascularization is preferred over surgical approaches 5, 6, 7
- The European Society of Cardiology guidelines recommend that endovascular treatment may be considered as first-line therapy, especially in patients with increased surgical risk or inadequate autologous veins (Class IIb) 2, 3
Patient Selection for DVA
- Patients with multiple high-risk comorbidities, such as end-stage renal disease (ESRD) on peritoneal dialysis, heart failure with reduced ejection fraction (HFrEF), and diabetes, may benefit from DVA 5, 6, 7
- The presence of extensive calcific disease and lack of conventional revascularization options may also indicate DVA as a suitable treatment option 2, 3
Inpatient Stay Justification
- The American College of Cardiology and American Heart Association guidelines emphasize that critical limb ischemia management must be determined on a case-by-case basis, considering the urgency of clinical presentation and the presence of comorbidity 5, 6, 7
- The European Society of Cardiology guidelines mandate regular follow-up and assessment of clinical, haemodynamic, and functional status after CLTI revascularization 2, 3, 10
- Inpatient monitoring is justified for patients with multiple high-risk comorbidities and those undergoing novel procedures like DVA 5, 6, 10
Post-Procedure Care
- Clinical assessment of limb perfusion and neurological status is necessary after DVA 8
- Monitoring for compartment syndrome, which requires emergent fasciotomy if it develops, is crucial after revascularization 8, 9
- Anticoagulation management and coordination of dialysis schedule are also important aspects of post-procedure care 8
