Secondary Raynaud\u2019s phenomenon (RP) is among the most common symptoms in systemic sclerosis and several other systemic autoimmune diseases including a broad differential diagnosis. It should be also differential from other peripheral vascular syndromes such as embolism, thrombosis, etc., some of which lead to clinical manifestation of the blue toe syndrome.<\/jats:p><jats:p>The current review discusses the instrumental methods for vascular assessments.<\/jats:p><jats:p>Nailfold capillaroscopy is the only method among the imaging techniques that can be used for morphological assessment of the nutritive capillaries in the nailfold area. Laser-Doppler flowmetry and laser-Doppler imaging are methods for functional assessment of microcirculation, while thermography and plethysmography reflect both blood flow in peripheral arteries and microcirculation. Doppler ultrasound and angiography visualize peripheral arteries. The choice of the appropriate instrumental method is guided by the clinical presentation. The main role of capillaroscopy is to provide differential diagnosis between primary and secondary RP. In rheumatology, capillaroscopic changes in systemic sclerosis have been recently defined as diagnostic. The appearance of abnormal capillaroscopic pattern inherits high positive predictive value for the development of a connective tissue disease that is higher than the predictive value of antinuclear antibodies. In cases of abrupt onset of peripheral ischaemia, clinical signs of critical ischaemia, unilateral or lower limb involvement, Doppler ultrasound and angiography are indicated. The most common causes for such clinical picture that may be referred to rheumatologic consultation are the antiphospholipid syndrome, mimickers of vasculitides such as atherosclerosis with cholesterol emboli, and neoplasms.<\/jats:p>","DOI":"10.1515\/folmed-2016-0011","type":"journal-article","created":{"date-parts":[[2016,8,23]],"date-time":"2016-08-23T09:50:35Z","timestamp":1471945835000},"page":"77-88","source":"Crossref","is-referenced-by-count":7,"title":["The Place of Nailfold Capillaroscopy Among Instrumental Methods for Assessment of Some Peripheral Ischaemic Syndromes in Rheumatology"],"prefix":"10.1515","volume":"58","author":[{"given":"Sevdalina N.","family":"Lambova","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","reference":[{"key":"ref211","doi-asserted-by":"crossref","first-page":"183","DOI":"10.1002\/art.1780230208","article-title":"Diagnostic potential of in vivo capillary microscopy in scleroderma and related disorders","volume":"23","author":"Maricq","year":"1980","journal-title":"Arthritis Rheum"},{"key":"ref511","doi-asserted-by":"crossref","first-page":"2747","DOI":"10.1002\/art.22734","article-title":"Hand vascular involvement assessed by magnetic resonance angiography in systemic sclerosis","volume":"56","author":"Allanore","year":"2007","journal-title":"Arthritis Rheum"},{"key":"ref131","doi-asserted-by":"crossref","first-page":"62","DOI":"10.1111\/j.1468-3083.2004.00853.x","article-title":"Nailfold digital capillaroscopy in patients with connective tissue disease and Raynaud s disease","volume":"18","author":"Nagy","year":"2004","journal-title":"J Europ Acad Dermatol Venerol"},{"key":"ref51","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.jaad.2008.09.038","article-title":"Blue ( or purple ) toe syndrome","volume":"60","author":"Hirschmann","year":"2009","journal-title":"J Am Acad Dermatol"},{"key":"ref11","first-page":"319","article-title":"Raynaud s Phenomenon : State of the Art","volume":"27","author":"Ho","year":"1998","journal-title":"Scand J Rheumatol"},{"key":"ref441","doi-asserted-by":"crossref","first-page":"97","DOI":"10.1016\/j.atherosclerosis.2003.11.015","article-title":"Non -
