Objective To evaluate the feasibility and safety of using arterial watershed analysis in the localization of pul-monary ground glass nodules during thoracoscopic wedge resection.Methods A total of 146 patients with thoracoscopic wedge resection admitted to the Department of Thoracic Surgery,the First Affiliated Hospital of Bengbu Medical Universi-ty from November 2021 to July 2023 were selected as research subjects,and the patients were divided into control group(n=73,traditional CT scan coil positioning)and observation group(n=73,identified by arterial watershed analysis)by random number table method.The localization effects of the two groups were compared.Results In the control group,5 patients were not suitable for CT scan localization due to the special location of nodules after safety evaluation by physi-cians,and they were transferred to the observation group and successfully localized by watershed analysis of the artery.The hospitalization cost of the observation group[(24 808.66±1 762.28)yuan]was lower than that of the control group[(25 776.73±1 723.93 yuan),t=3.350,P＜0.05].The incidence of perioperative complications in the observation group was 769％(6/78),which was lower than 26.47％(18/68)in the control group(x2=9.326,P＜0.05).The success rate of first resection in the observation group was 94.87％(74/78),which was higher than 83.82％(57/68)in the control group(x2=4.810,P＜0.05).There was no significant difference-in positioning time,intraoperative blood loss,drainage volume on the first day after surgery,extubation time and pathological type data between the two groups(P＞0.05).Conclusion The watershed analysis of artery localization method is a potential new localization method for pulmonary nodules,which can effectively ensure the safe surgical margin,improve the success rate of nodule resection at the first time,reduce the hospitalization cost and the incidence of perioperative complications,and the localization is sim-ple,especially suitable for pulmonary nodules in special locations.It is easily accepted by patients and worthy of clinical application.
