IRT was used to detect lower limb skin temperature. Locations on the lower extremity sampled with IRT were dorsal areas, plantar areas, and medial and lateral areas of the calves.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>One hundred twenty-eight limbs of 64 patients were divided into normal (n=35), mild (n=22), moderate (n=55), and severe (n=16) groups based on the ankle-brachial index (ABI) testing. Limbs in the moderate and severe groups showed an obvious decrease in surface temperature when compared to the normal baseline measurements, particularly in the dorsal areas (all p values &lt;0.01). Further analysis revealed IRT increased the sensitivity of ABI from 75.8% (69\/91) to 96.7% (88\/91) in PAD diagnosis. In addition, our results showed maximum temperature variations (\u0394TEMP) on treated limbs decreased significantly after endovascular treatment. Further analysis revealed showed a negative correlation between maximum \u0394TEMP on treated limbs and walking distance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Our findings showed the use of IRT increased the diagnostic efficacy of ABI in BTK PAD patients.

The high prevalence of medial sclerosis, which can render arteries incompressible upon cuff inflation, may lead to falsely elevated ABI values (ABI&gt;1.4) in patients with diabetes mellitus. Infrared thermography (IRT) is a novel potential diagnostic method that does not require physical contact. The use of IRT may increase the diagnostic efficacy of ABI in BTK PAD patients. This non-invasive technique has the potential to be applied in PAD diagnosis, preoperative, and postoperative evaluation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15266028251356459","type":"journal-article","created":{"date-parts":[[2025,7,13]],"date-time":"2025-07-13T11:31:21Z","timestamp":1752406281000},"page":"2545-2554","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Effectiveness of Infrared Thermography Combined With Ankle-Brachial Index in the Assessment of Patients With Below-the-Knee Periphery Artery Diseases"],"prefix":"10.1177","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0524-2693","authenticated-orcid":false,"given":"Zhenyu","family":"Guo","sequence":"first","affiliation":[{"name":"Department of Vascular Surgery, Qingpu Branch of Zhongshan Hospital affiliated to Fudan University, Shanghai, China"},{"name":"Department of Vascular Surgery, Zhongshan Hospital, Institute of Vascular Surgery, Fudan University, Shanghai, China"},{"name":"National Clinical Research Center for Interventional Medicine, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin","family":"Patterson","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, University Hospital Southampton, Southampton, UK"},{"name":"Clinical Experimental Sciences, University of Southampton, Southampton, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuyang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Zhongshan Hospital, Institute of Vascular Surgery, Fudan University, Shanghai, China"},{"name":"National Clinical Research Center for Interventional Medicine, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenyu","family":"Shi","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Zhongshan Hospital, Institute of Vascular Surgery, Fudan University, Shanghai, China"},{"name":"National Clinical Research Center for Interventional Medicine, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4488-4464","authenticated-orcid":false,"given":"Daqiao","family":"Guo","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Zhongshan Hospital, Institute of Vascular Surgery, Fudan University, Shanghai, China"},{"name":"National Clinical Research Center for Interventional Medicine, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2252-437X","authenticated-orcid":false,"given":"Longhua","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Qingpu Branch of Zhongshan Hospital affiliated to Fudan University, Shanghai, China"},{"name":"Department of Vascular Surgery, Zhongshan Hospital, Institute of Vascular Surgery, Fudan University, Shanghai, China"},{"name":"National Clinical Research Center for Interventional Medicine, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0229-5688","authenticated-orcid":false,"given":"Baolei","family":"Guo","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Zhongshan Hospital, Institute of Vascular Surgery, Fudan University, Shanghai, China"},{"name":"National Clinical Research Center for Interventional Medicine, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5025-8542","authenticated-orcid":false,"given":"Weiguo","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Zhongshan Hospital, Institute of Vascular Surgery, Fudan University, Shanghai, China"},{"name":"National Clinical Research Center for Interventional Medicine, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,7,13]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2021.2126"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s13679-023-00510-7"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0140-6736(13)61249-0"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/s2214-109x(23)00355-8"},{"key":"e_1_3_3_6_2","first-page":"362","article-title":"Lower extremity peripheral artery disease: diagnosis and treatment","volume":"99","author":"Firnhaber JM","year":"2019","unstructured":"Firnhaber JM, Powell CS.
