RESUMEN
Heavily calcified arterial lesions are difficult to treat in an endovascular manner with conventional techniques due to limited arterial compliance. Intravascular lithotripsy offers a novel minimally invasive therapeutic option through endovascular emission of acoustic waves, fracturing calcium deposits and facilitating lesion dilation. We present the case of a successful application of the Shockwave intravascular lithotripsy system (IVL®, Shockwave Medical Inc) in a heavily calcified stenosis of the right renal artery in a patient with a coral reef aorta.

Diabetic foot infection (DFI) is an important risk factor for amputation, and late diagnosis or referral is often incriminated for poor outcome. To enable an earlier diagnosis of DFI, comparative foot thermometry has been suggested as a self-screening method for patients in a home setting. We validated the efficacy of the ThermoScale, a weighing scale outfitted with temperature sensors that allows accurate temperature measurement in both feet. Temperature differentials in DFI patients (n = 52) were compared with a control group of similar diabetic patients (n = 45) without any foot wounds. Based on these findings, we drafted a receiver operating characteristic curve to determine an area-under-the-curve of 0.8455. This value suggests that the ThermoScale, as a diagnostic test, is reasonably accurate. A cutoff value of 2.15 °C temperature difference corresponded with a sensitivity of 88.9% and a specificity of 61.5%. As wearables, portable health electronics, and telemedicine become increasingly popular, we think that comparative temperature measurement technology is valuable in improving early diagnosis of DFIs.

OBJECTIVE/BACKGROUND: Carotid artery stenting (CAS) is a valuable solution for the treatment of carotid artery stenosis in a high-risk patient population for carotid endarterectomy (CEA). In literature however, there are concerns about the death and stroke rates of CAS in the 'real world' practice. Since Belgium is a small country with a broad offer of medical care, and there is no reimbursement for CAS, only small numbers of patients can be treated per vascular department. METHODS: In our department 45 CAS were performed from January 2006 until May 2018. Patient characteristics, indication for treatment and choice of treatment, minor stroke, major stroke and death rates were analyzed retrospectively. RESULTS: Of these patients 8/45 (18%) had a symptomatic carotid artery stenosis and 37/45 (82%) had an asymptomatic stenosis. A total minor stroke rate of 3/45 (6.6%) was recorded, but no major stroke (0%) or death (0%). Of the 37 patients who were asymptomatic at the start, 1 suffered a minor stroke (1/37, 2.7%) peri-operatively. CONCLUSION: Real world data from a low volume center show that CAS performed in patients with high risk for CEA yields acceptable outcome that is comparable to the literature. Since CAS is a delicate procedure we advice to centralize the procedure to an dedicated experienced interventionalist and to perform rigorous quality control of your 'real world' data.

Multiple simple renal cysts have been linked to aortic aneurysm and connective tissue disease by different authors. We present a case of a 64-year-old male patient with multilevel, rapid progressive aneurysmatic disease. Over a period of 11 years, he sequentially developed a symptomatic infrarenal aortic aneurysm of 100 mm, a juxtarenal progression of the aneurysm up to 61 mm, an aneurysm on the descending thoracic aorta of 73 mm, and a common iliac aneurysm of 53 mm. In addition, he developed an aneurysm of 69 mm of the left superficial femoral artery and an aneurysm of 53 mm of the right profunda femoris artery. Although the exact relationship between multiple simple renal cysts and arterial aneurysm formation is not known, there is a suggestion that they can be a marker for arterial aneurysmatic disease. We therefore would advocate a more thorough follow-up in case of aneurysmatic disease in a patient with known multiple simple renal cysts.
