Abstract:

Objective： To explore the clinical application value of percutaneous puncture biopsy guided by contrast-enhanced ultrasound （CEUS） in peripheral lung lesions. Methods： The medical records of 72 patients with peripheral lung lesions who underwent percutaneous puncture biopsy under ultrasound guidance from January 2017 to August 2021 in Qujing Hospital Affiliated to Kunming Medical University were retrospectively analyzed. According to whether CEUS was performed before biopsy， the patients were divided into CEUS group and conventional ultrasound（CU） group. The necrotic lesion display， number of puncture needles， puncture success rate， initial puncture diagnosis rate， and incidence of complications between the two groups were compared and analyzed. Results：The display rate of necrotic lesion， puncture success rate and first puncture diagnosis rate in CEUS group were significantly higher than those in CU group， and the number of puncture needles was significantly lower than that in CU group. All differences were statistically significant（P<0.05）. Within 48 hours after puncture， one patient in each group had hemoptysis， and there was no statistically significant difference in the incidence of complications（P>0.05）. Conclusion： Percutaneous puncture biopsy guided by contrast-enhanced ultrasound can effectively identify the active tissue in peripheral lung lesions， improve the puncture success rate， and is safe and effective. It is worth promoting in clinical practice.
