“…Estimated glomerular filtration rate (eGFR) was calculated using the Chronic Kidney Disease–Epidemiology Collaboration (CKD‐EPI) formula, as the authors had previously found this to be most accurately associated with complications in patients with PAD. A subset of included patients had the severity of PAD assessed by ankle : brachial pressure index (ABPI) and the ANGIO score measured by Doppler assessment and CT–angiography respectively, as described in detail previously.…”

“…At recruitment, each patient's medications were recorded including whether they were prescribed a statin, aspirin, another antiplatelet agent, beta‐blocker, calcium channel blocker, angiotensin‐converting enzyme inhibitor, angiotensin receptor blocker, anticoagulants (warfarin or new anticoagulants), metformin, insulin, other diabetes medications or frusemide (for the treatment of cardiac failure).…”

“…The primary outcome of the study was major amputation, including above‐ and below‐knee amputations. Secondary outcomes were the requirement for subsequent revascularization and the incidence of myocardial infarction, stroke and all‐cause mortality, as defined previously. Subsequent revascularization represented a second revascularization procedure for the patients undergoing early revascularization or a first revascularization procedure for those initially treated conservatively.…”

Background: With severe vascular calcifications, vascular clamp application and utilizing the vessel for free flap recipient vessel becomes impossible. These obstacles can be overcome with the Fogarty catheter and vein graft.Patients and methods: When unclampable artery was encountered intraoperatively, a vein graft was used to make a clampable recipient site for six diabetic foot patients (ages from 42 to 80). The end of the Fogarty catheter was inserted into the proximal end of the vein graft and the transected calcified vessel in sequence, and the balloon of the catheter was used as an intraluminal tourniquet. The remaining end of the vein graft was connected to the distal vessel with a vascular clamp.Results: Five short vein graft revascularization for segmental arterial occlusion, one long vein graft for recipient artery elongation was done (lengths from 2 to 13.8 cm).Three delayed, and two immediate anterolateral thigh flaps (sizes from 15 to 150 cm 2 ) were performed, and one patient received vein graft revascularization surgery only. Postoperative vascular sonography of all six patients showed wellmaintained patency. Minor flap marginal disruption occurred at two patients but healed with conservative care. Postoperative follow-up was done for 1-18 months (average 7.17). Limb salvage was achieved for five patients and all five free flaps survived. However, for one patient, arterial restenosis at popliteal artery a month later lead to major amputation. Conclusion:Using a Fogarty catheter and a vein graft may obtain perfect hemostasis during micro-anastomosis and achieve successful microvascular reconstruction in patients with severely calcified vessels.

Association between aortic peak wall stress and rupture index with abdominal aortic aneurysm–related events

Objective The aim of this study was to assess whether aortic peak wall stress (PWS) and peak wall rupture index (PWRI) were associated with the risk of abdominal aortic aneurysm (AAA) rupture or repair (defined as AAA events) among participants with small AAAs. Methods PWS and PWRI were estimated from computed tomography angiography (CTA) scans of 210 participants with small AAAs (≥ 30 and ≤ 50 mm) prospectively recruited between 2002 and 2016 from two existing databases. Participants were followed for a median of 2.0 (inter-quartile range 1.9, 2.8) years to record the incidence of AAA events. The associations between PWS and PWRI with AAA events were assessed using Cox proportional hazard analyses. The ability of PWS and PWRI to reclassify the risk of AAA events compared to the initial AAA diameter was examined using net reclassification index (NRI) and classification and regression tree (CART) analysis. Results After adjusting for other risk factors, one standard deviation increase in PWS (hazard ratio, HR, 1.56, 95% confidence intervals, CI 1.19, 2.06; p = 0.001) and PWRI (HR 1.74, 95% CI 1.29, 2.34; p < 0.001) were associated with significantly higher risks of AAA events. In the CART analysis, PWRI was identified as the best single predictor of AAA events at a cut-off value of > 0.562. PWRI, but not PWS, significantly improved the classification of risk of AAA events compared to the initial AAA diameter alone. Conclusion PWS and PWRI predicted the risk of AAA events but only PWRI significantly improved the risk stratification compared to aortic diameter alone. Key Points • Aortic diameter is an imperfect measure of abdominal aortic aneurysm (AAA) rupture risk. • This observational study of 210 participants found that peak wall stress (PWS) and peak wall rupture index (PWRI) predicted the risk of aortic rupture or AAA repair. • PWRI, but not PWS, significantly improved the risk stratification for AAA events compared to aortic diameter alone.

Assessment and validation of a novel angiographic scoring system for peripheral artery disease

Abstract: The ANGIO score provided a reproducible and valid assessment of the severity of lower-limb ischaemia and risk of major amputation and cardiovascular events in these patients with peripheral artery disease.
