It is important to distinguish the concept of vascular disease and vasculitis: vasculopathy encompasses any disease that affects a vessel, while vasculitis is the inflammatory disease of a vessel due to an impaired immune system. In this review we will focus primarily on two uncommon manifestations of scleroderma, such as the involvement of large vessels and non-digital ulcers.

Instead, the aetiology of non-digital ulcers in patients with SSc are mostly by arterial involvement and appear on extensor surfaces and bony prominences (metacarpophalangeal joints, proximal interphalangeal joints, elbows, ankles, pretibial and forefoot regions). Lower extremity ulcers are often extensive, making it necessary to perform a differential diagnosis in those of vasculitic origin.<a class="elsevierStyleCrossRef" href="#bib0300"><span class="elsevierStyleSup">2</span></a> Also, areas where there is subcutaneous calcinosis are more likely to ulcerate.</p><p id="par0095" class="elsevierStylePara elsevierViewall">While vasospasm plays a fundamental role in the digital ulcers themselves, in the case of non-digital ulcers, repeated microtrauma is the main risk factor in areas of chronic contracture and atrophic skin. Others are thinning of the skin, loss of elasticity and peripheral neurological impairment that hinders tissue regeneration and repair, which results in chronic ulcers, making them more vulnerable to infection. These ulcers respond less well to treatment with vasodilating agents compared to distal location ones.</p><p id="par0100" class="elsevierStylePara elsevierViewall">In a recent publication by Shanmugam et al.,<a class="elsevierStyleCrossRef" href="#bib0440"><span class="elsevierStyleSup">30</span></a> 249 cases of patients with limited and diffuse SSc were reviewed. Non digital ulcer was defined as a lower extremity dermoepidermal lesion, of more than 3 months’ progression, which has not improved despite standard treatment. The prevalence of non-digital and lower limbs ulcers was 4% (n<span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>10). Seven patients had bilateral ulcers and 3 unilateral. Ulcer biopsy was performed in 50% of cases and fibrosis stood out histologically. None was compatible with vasculitis. An autoimmune genetic study was requested and it was observed that patients with non-digital ulcer had heterozygous or homozygous mutation for gene <span class="elsevierStyleItalic">MTHFR-C677T</span> (methylene tetrahydrofolate reductase gene, enzyme involved in clotting) and positive antiphospholipid antibodies (without meeting the criteria for antiphospholipid syndrome). However, it is a study with only a few patients and would require a larger sample size to confirm this finding.</p><p id="par0105" class="elsevierStylePara elsevierViewall">Furthermore, Youssef et al.,<a class="elsevierStyleCrossRef" href="#bib0445"><span class="elsevierStyleSup">31</span></a> compared the prevalence of large vessel involvement (diagnosed by the absence of peripheral pulses in the physical examination, angiography or ultrasound Doppler) of 31 patients with limited SSc relative to a control group adjusted for age, sex and cardiovascular risk factors, observing that the prevalence of macrovascular disease was higher in the group of patients with limited SSc (58% versus 9%). However, no differences were found in the prevalence of coronary and cerebrovascular disease in any of the 2 groups.</p><p id="par0110" class="elsevierStylePara elsevierViewall">In turn, there are also cases of proximal vessel involvement in upper limbs, mainly the ulnar artery. Through arteriography, Hasegawa et al.,<a class="elsevierStyleCrossRef" href="#bib0450"><span class="elsevierStyleSup">32</span></a> evaluated the prevalence of large vessel involvement in the upper and lower limbs in 8 patients with SSc and ulcers. Macrovascular upper limb involvement was higher than the lower limbs (7/5). The vessels affected in the upper limbs were the ulnar and radial arteries, while in the lower they were the posterior tibial, the arcuate and the pedia arteries. The palmar and plantar arches were also affected. In another study,<a class="elsevierStyleCrossRef" href="#bib0455"><span class="elsevierStyleSup">33</span></a> with a larger sample size (20 patients with SSc), a Doppler ultrasound was performed, with the ulnar artery showing a narrower arterial lumen and an increased wall thickness compared to the control group, although no significant differences were found with other vessels.</p><p id="par0115" class="elsevierStylePara elsevierViewall">In short, virtually all the vascular system of patients with SSc may be affected.

Radiographic abnormalities appear to be of different types, including vascular attenuation patterns, intimal irregularities of the vessels or focal and proximal occlusions. No angiographic differences were found in this report in connection with limited or diffuse SSc. The only clinical manifestation of the disease that showed association with these vascular changes was pulmonary hypertension, however, this is not described when the origin of these changes is arteriosclerotic, inflammatory, vasculitic or otherwise. Park et al.,<a class="elsevierStyleCrossRef" href="#bib0480"><span class="elsevierStyleSup">38</span></a> retrospectively describe the findings observed in the ulnar artery by arteriography.

In this regard, Rosato et al.,<a class="elsevierStyleCrossRef" href="#bib0485"><span class="elsevierStyleSup">39</span></a> describe ultrasound palmar artery pathological patterns in 36 patients with SSc compared with 20 controls. However, this involvement was not related to the presence of digital ulcers.

It is essential to conduct a thorough case history emphasizing the presence of cardiovascular risk factors and symptoms and/or signs suggestive of vasculopathy or vasculitis. On physical examination, all peripheral pulses should be palpated, performing the Allen, the Adson and the hyperabduction tests, which will help in assessing the patency of the radial and ulnar artery and the presence of vascular or neural compression. Doppler ultrasound and angiography will help in determining the degree of vascular involvement and, if possible, revascularization by angioplasty. Lab tests with screening for vasculitis are also necessary, and if in doubt, a tissue biopsy is a choice procedure to reach a definitive diagnosis. The diagnosis of one or the other is as complicated as essential, as the therapeutic approach is far from similar. Treatment depends on the degree of vascular involvement and the cause behind it.</p><p id="par0190" class="elsevierStylePara elsevierViewall">In the case of digital ulcers, non-pharmacological and pharmacological measures (antiplatelet and vasodilator agents) should be taken into account.<a class="elsevierStyleCrossRef" href="#bib0575"><span class="elsevierStyleSup">57</span></a> Non-digital ulcers are often refractory to conventional treatment and very painful, so the analgesic treatment should be adequate and revascularization should always be considered as first choice in these patients. Surgical sympathectomy could be an alternative when revascularization is not possible, although not always effective.<a class="elsevierStyleCrossRef" href="#bib0580"><span class="elsevierStyleSup">58</span></a> Antibiotic treatment of superinfected lesions to prevent osteomyelitis and sepsis is also paramount. If there is an underlying vasculitis, this should be treated urgently to prevent a fatal outcome.</p><p id="par0195" class="elsevierStylePara elsevierViewall">SSc is a rare disease among the connective tissue diseases and this complicates conducting clinical trials, and therefore, researching the pathogenesis of vascular involvement and developing new therapies. It is important to know each and every one of the different manifestations of macrovascular disease, as these may vary in each patient, hindering diagnosis and early treatment. However, with what has been published so far, there is enough data to enable us to approach the correct diagnosis.</p></span><span id="sec0065" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0085">Conflict of interests</span><p id="par0200" class="elsevierStylePara elsevierViewall">The authors declare no conflict of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:10 [ 0 => array:3 [ "identificador" => "xres632579" "titulo" => "Abstract" "secciones" => array:1 [ 0 => array:1 [ "identificador" => "abst0005" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec645273" "titulo" => "Keywords" ] 2 => array:3 [ "identificador" => "xres632580" "titulo" => "Resumen" "secciones" => array:1 [ 0 => array:1 [ "identificador" => "abst0010" ] ] ] 3 => array:2 [ "identificador" => "xpalclavsec645272" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:3 [ "identificador" => "sec0010" "titulo" => "Pathogenesis of vascular involvement in systemic sclerosis" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Impairment of microcirculation" ] 1 => array:2 [ "identificador" => "sec0020" "titulo" => "Endothelial dysfunction and impaired pericytes" ] 2 => array:2 [ "identificador" => "sec0025" "titulo" => "Impaired angiogenesis and vasculogenesis" ] 3 => array:2 [ "identificador" => "sec0030" "titulo" => "Chronic platelet activation and impaired platelet aggregation" ] ] ] 6 => array:3 [ "identificador" => "sec0035" "titulo" => "Clinical manifestations of vasculopathy in systemic sclerosis" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "sec0040" "titulo" => "Raynaud's phenomenon and digital ulcers" ] 1 => array:2 [ "identificador" => "sec0045" "titulo" => "Non digital ulcers" ] 2 => array:2 [ "identificador" => "sec0050" "titulo" => "Arteriosclerosis and systemic sclerosis" ] 3 => array:2 [ "identificador" => "sec0055" "titulo" => "Vasculitis" ] ] ] 7 => array:2 [ "identificador" => "sec0060" "titulo" => "Conclusions" ] 8 => array:2 [ "identificador" => "sec0065" "titulo" => "Conflict of interests" ] 9 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2014-09-30" "fechaAceptado" => "2014-12-11" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec645273" "palabras" => array:3 [ 0 => "Systemic sclerosis" 1 => "Vasculopathy" 2 => "Large vessels" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec645272" "palabras" => array:3 [ 0 => "Esclerosis sistémica" 1 => "Vasculopatía" 2 => "Gran vaso" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:2 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">Vasculopathy in systemic sclerosis is a severe, in many cases irreversible, manifestation that can lead to amputation.
