Critical limb ischemia (CLI), defined as ischemic rest pain or nonhealing ulceration due to arterial insufficiency, represents the most severe and limb-threatening manifestation of peripheral artery disease. A major challenge in the optimal treatment of CLI is that multiple specialties participate in the care of this complex patient population. As a result, the care of patients with CLI is often fragmented, and multidisciplinary societal guidelines have not focused specifically on the care of patients with CLI. Furthermore, multidisciplinary care has the potential to improve patient outcomes, as no single medical specialty addresses all the facets of care necessary to reduce cardiovascular and limb-related morbidity in this complex patient population. This review identifies current gaps in the multidisciplinary care of patients with CLI, with a goal toward increasing disease recognition and timely referral, defining important components of CLI treatment teams, establishing options for revascularization strategies, and identifying best practices for wound care post-revascularization.

Artery Disease

Background: Chronic limb-threatening ischemia is a severe form of peripheral artery disease that leads to high rates of amputation and mortality if left untreated. Bypass surgery and antegrade endovascular revascularization through femoral artery access from either side are accepted as conventional treatment modalities for critical limb ischemia. The retrograde pedal access revascularization is an alternative treatment modality useful in specific clinical scenarios; however, these indications have not been well described in literature. This case report highlights the use of retrograde pedal access approach as primary treatment modality in a patient with an extensive comorbidities precluding general anesthesia nor supine positioning. Case Presentation: The patient is a 60-year-old female with multiple severe cardiopulmonary comorbidities presenting with dry gangrene of the right great toe. Her comorbidities and inability to tolerate supine positioning precluded her from receiving open surgery, general anesthesia or monitored sedation, or percutaneous femoral access. Rather, the patient underwent ankle block and retrograde endovascular revascularization via dorsalis pedis artery access without post-operative complications. Discussion: The prevalence of comorbidities related to peripheral artery disease is increasing and with it the number of patients who are not optimal candidates for conventional treatment methods for critical limb ischemia. The retrograde pedal access revascularization as initial treatment modality offers these patients an alternative limb salvaging treatment option.

Background Cystic adventitial disease (CAD) is an important and rare non-atherosclerotic cause of intermittent claudication and critical limb ischemia. Since the first case of CAD involving the external iliac artery was described by Atkins and Key in 1947, approximately 300 additional cases have been reported. Objectives The aim of this article is to report a rare vascular disorder, predominantly seen in young healthy men with minimal cardiovascular risk factors. Methods We report a rare case of cystic adventitial disease of a young policeman. To confirm the diagnosis, an ultrasonography and a conventional angiography were performed. The therapeutic approach was surgical first. Results The procedure was successful without any complication, and the patient was discharged to home 4 days after procedure. Conclusion While CAD is rare, the diagnosis should be suspected in a young patient who presents with arterial insufficiency and no risk factors for atherosclerosis. Catheter angiography is the investigation of choice in the absence of multislice CT and good MRA. It seems that the treatment that assures the best long-term results is reconstructive arterial bypass surgery.

Lower Extremity Revascularization

Abstract Background and Aims Although lower extremity revascularization has been commonly performed in chronic haemodialysis (HD) patients with peripheral artery disease (PAD), poorer prognosis still remains major problems in such population. Recently, protein-energy wasting (PEW) or malnutrition have been considered to be strongly associated with chronic inflammation and advanced atherosclerosis in HD patients. We investigated the association of geriatric nutritional risk index (GNRI) as a surrogate marker of the PEW, C-reactive protein (CRP) and these joint role with prediction of amputation and/or mortality after lower extremity revascularization in chronic HD patients. Method We enrolled a total of 862 HD patients (age 67±10 years, diabetes 62.9%, critical limb ischemia 53.5%) who successfully underwent lower extremity revascularization (552 with endovascular therapy and 310 with bypass surgery). Patients were divided into tertiles according to GNRI levels; tertile 1 (T1): <80.0, T2: 80.0-96.6and T3: >96.6, and CRP levels; T1: <2.0mg/l, T2: 2.0-12.6mg/l and T3: >12.6mg/l, respectively. They were followed up for up to 8 years. Results During follow-up period (median: 43 months), 63 (7.3%) patients needed major amputation and 202 (23.4%) patients died. Kaplan-Meier analysis shows that amputation-free survival rates for 8 years were 47.5%, 51.6% and 66.5% in T1, T2 and T3 of GNRI, and were 65.8%, 58.7% and 33.2% in T1, T2 and T3 of CRP, respectively (p<0.0001 in both). After adjustment for age, previous coronary artery disease and critical limb ischemia as covariates with p<0.05 by univariate analysis, declined GNRI [hazard ratio (HR) 2.18, 95% confidence interval (CI) 1.57-3.07, p<0.0001 for T1 vs. T3] and elevated CRP (HR 1.78, 95%CI 1.24-2.59, p=0.0016 for T3 vs. T1) were identified as independent predictors of amputation and/or mortality. In the combined setting of both variables, the risk of amputation and/or mortality was 3.77-fold higher (95%CI 1.97-7.69, p<0.0001) in theT1 of GNRI with T3 of CRP than in the T3 of GNRI with T1 of CRP. Similar results were obtained for amputation and mortality, respectively (Figure). Conclusion Among HD patients undergoing lower extremity revascularization, those with pre-procedural declined GNRI and elevated CRP frequently experienced amputation and/or mortality, furthermore, combination of both variables could stratify the risk of amputation and/or mortality.
