We retrospectively reviewed 223 consecutive bypass surgery cases performed in 192 patients with CLI during a 10-year period. SPP was measured 1\u20132 weeks before and after the procedure. An SPP of 40 mmHg was set as the cut-off value for revascularization. Patients were grouped according to their postoperative SPPs, and amputation-free survival (AFS) was analyzed. An SPP of \u2265 40 mmHg was recovered in 75% of the patients, but no significant difference was found between this group and the group that did not reach 40 mmHg. On the other hand, the values increased by \u2265 20 mmHg from the preoperative values in 70% of the patients. This group had a significantly better AFS than the group that did not increase by 20 mmHg. Logistic regression analysis revealed that (1) a preoperative SPP of &lt; 20 mmHg and (2) a high serum albumin level (&gt; 3.0 g\/dL) were significant factors in increasing SPP by 20 mmHg. These results showed that an increase in SPP of \u2265 20 mmHg after bypass surgery was associated with better limb prognosis.<\/jats:p>","DOI":"10.1177\/1358863x18760181","type":"journal-article","created":{"date-parts":[[2018,4,23]],"date-time":"2018-04-23T07:39:59Z","timestamp":1524469199000},"page":"243-249","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Increase
