The Analysis Of CT-guided Percutaneous Chest Biopsy Puncture Clinical Application And Complications Prevention

Object：To observe CT guided percutaneous biopsy chest intraoperative complications associated withpostoperative in affirming it’s clinical application value basis.To analyze the cause of complication and themain influence factors and propose effective prevention and treatment method to further improve thesuccess rate of puncture.Methods：Retrospective analysis of191cases with complete image data since the Jun2005to Jun2012.Statistics191cases of CT guided percutaneous chest biopsy puncture success rate and relatedcomplications.Results：191cases of percutaneous chest biopsy are puncture success, puncture success rate100%.Thepneumothorax occurred46cases, the incidence of24%,A small amount of pneumothorax in45patients(lung tissue is compressed to less than30%),ward observed two hours, without making special handling, afew days later self absorption.1cases of lung tissue compression is more than30%, timely do chestpuncture pumping gas, the symptom is reduced, get better, do not make other special treatment, clinicalobservation a few days later self absorption.Pulmonary hemorrhage51cases and its incidence was27%,among which46cases with a small amount of bleeding, not special clinical treatment.5patients withmoderate amount bleeding,The clinical manifestations is with big hemoptyses, do oral hemostaticdrugs,clinical observation2-3days，hemoptyses stops.Subcutaneous emphysema1case.Conclusion:1. CT guided percutaneous chest biopsy is characteristic of accurate positioning, high successrate;2. Pneumothorax, bleeding is the most common complication of CT guided percutaneous chest biopsy,tumor planting transfer is very rare;3.Impact complications factors including the patient’s quality, puncturelesion size, lesion distance chest wall depth, number of puncture in the lungs;4.Further improve the successrate and reduce complications include: the principle of strict case selection; appropriate CT scan postural; astrict CT scan positioning requirements; precise puncture point and the puncture channel selection principle(very critical); skillful puncture skills; effective specimen collection principle; patients the ability to controlevery breath the magnitude and extent of breath; Active prevention, accurate judgment and effectivetreatment for complications.
