Abstract:
Objective To explore the efficiency and safety of trans-sheath intraluminal forceps biopsy under digital subtraction angiography(DSA)guidance for assisting diagnosis of pulmonary artery obstructive diseases.Methods Data of 16 patients who underwent trans-sheath intraluminal forceps biopsy for pulmonary artery obstructive diseases were retrospectively analyzed,and the clinical manifestations were recorded.The technical success of biopsy was defined as tissue obtained met the needs of pathology diagnosis.For patients with malignant pathology results,the final diagnosis was malignant,for those with benign pathology results after biopsy and no obvious changes after 6-month or longer follow-up,or benign pathology results after surgical resection,the final diagnosis was benign,otherwise was no clear diagnosis.The operation time,technical success rate,diagnostic efficiency,complications and changes of pulmonary artery pressure before and after the biopsy were observed.Results Among 16 patients,9 complained of intermittent chest tightness,4 complained of chest pain with chest tightness,2 complained of chest pain but 1 denied any symptoms.The lesions located in the left lung in 10 cases and in the right lung in 6 cases,all with enhanced CT showed filling defects of the involved branch of pulmonary artery.Totally 16 trans-sheath intraluminal forceps biopsies were performed in 16 patients,with an average operation time of(31.02±6.02)min and technical success rate of 100%.Malignant tumors were finally diagnosed in 10 cases,including 1 case of lung cancer with false-negative biopsy result,while biopsy correctly diagnosed benign lesions in the other 6 cases.Transient worsening chest pain with chest tightness occurred in 2 cases and relieved after symptomatic treatments.No statistically significant difference of pulmonary artery pressure was found before([53.38±14.28]mmHg)and after([53.69±14.15]mmHg)biopsy(P＞0.05).Conclusion DSA-guided trans-sheath intraluminal forceps biopsy was relatively safe and valuable for assisting diagnosis of pulmonary artery obstructive diseases.
