To explore the clinical effect of physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) score combined with acute physiology and chronic health evaluation (APACHE) II score on interventional therapy of lower extremity arteriosclerosis obliterans.

The clinical data of 48 patients with lower extremity arteriosclerosis obliterans treated with routine interventional therapy were retrospectively analyzed from May 2013 to April 2018 in our hospital, who were set up as A group, and the clinical data of 48 patients with lower extremity arteriosclerosis obliterans treated with interventional therapy on the guiding of preoperative POSSUM and APACHE II evaluation were retrospectively analyzed at the same period in our hospital, who were set up as B group. The success rate of interventional operation and hospitalization time of the 2 groups were compared, and the blood flow of posterior tibial artery and dorsal pedal artery and ankle brachial index (ABI) before and after treatment were compared, then the incidence of postoperative complications and the death situation were compared.

The success rate of operation in B group was significantly higher than that in A group (95.83% vs. 83.33%) , and the hospitalization time of B group was significantly shorter than that of A group[ (9.47±2.64) d vs. (14.56±3.28) d], with significantly statistical differences (χ²=4.019, t=8.375, both P<0.05) . The blood flow of posterior tibial artery and dorsal pedal artery of the 2 groups after treatment were significantly higher than those before treatment (P<0.05) , and those in B group after treatment were significantly higher than those of A group (P<0.05) . There was no significant difference in the ABI index before treatment between the 2 groups (P>0.05) , and those in the 2 groups after treatment were significantly higher than those before treatment (P<0.05) , and those in the B group after treatment was significantly higher than that of the A group[ (1.09±0.22) vs. (0.95±0.14) ], with a significantly statistical difference (t=3.785, P<0.05) . The incidence rate of postoperative total complications of the B group was lower than that of the A group (12.50% vs. 29.17%) , and the mortality rate of the B group was lower than that of the A group (0% vs. 8.33%) , with significantly statistical differences (both P<0.05) .

POSSUM score combined with APACHE II score guiding the interventional therapy of lower extremity arteriosclerosis obliterans can obviously improve the success rate of interventional operation, shorten the hospitalization time, improve the blood flow of lower limbs and ABI, and reduce the postoperative complications and death.
