Percutaneous CT-guided lung biopsy has excellent sensitivity and specificity for the diagnosis of persistent lung consolidation due to malignant condition. Pneumothorax has a broad frequency range of 8 to 64%. CT guided lung biopsy is a very safe procedure, but there are a few risks and complications that can arise, as with any medical procedure. Percutaneous transthoracic biopsies are commonly performed for the diagnosis of thoracic lesions. The patient should be placed in the decubitus position with the biopsy side dependent to prevent spillage of blood into the contralateral lung. CT-Guided Percutaneous Needle Biopsy of the Chest: Preprocedural Evaluation and Technique, Pictorial Essay. Frequent complications in CT-guided lung biopsy A recent meta-analysis, comprising 8133 CNB and 4620 FNA procedures, reported overall complication rates of 38.8% with 5.7% severe complications for CNB, versus 24% and 4.4% for FNA, respectively. Yeow et al reported a sixfold increase in bleeding complications for patients with lesions ≤ 2 cm in size compared with those having lesions > 4 cm in size. In a large series of 9783 biopsies, there were only six cases (0.061%) of air embolism [11]. Air embolism and tumor seeding of the pleura and chest wall are rare complications of needle biopsy of the chest. CT-guided cutting needle lung biopsy using modified coaxial technique: factors effecting risk of complications. For core biopsy, no significant risk factors were identified. Objectives To evaluate frequency and severity of complications after CT-guided lung biopsy using the Society of Interventional Radiology (SIR) classification, and to assess risk factors for overall and major complications. Transthoracic needle aspiration biopsy: variables that affect risk of pneumothorax. … In CT-guided transthoracic lung biopsy (CTLB), pneumothorax can occur as a late complication (delayed pneumothorax). Background Patients with a suspected malignant lung lesion require a diagnostic histopathology, and CT-guided biopsy is a safe and widely used method for obtaining peripheral lung tissue (Connor et al. The median follow-up of the patients with confirmed diagnosis after the CNB was 18.3 ± 10.9 months. Patients are instructed not to move, talk, cough, or breathe deeply during and immediately after the procedure. D, CT scan shows near complete resolution of pneumothorax after aspiration. Early reports of needle biopsies of the lung were published in the late 1800s. The complications rate in control group was similar, hemorrhage in 33% (19/39) (p=0.6), moderate hemoptysis in 5% (2/39) (p=0.3), pneumothorax in 28% (11/39) (p=0.2), chest tube in (0/39) (p=0.3), and hemothorax in 3% (1/39) of the patients (p=0.7). Fig. 2000; Winokur et al. The catheter can be attached to a one-way Heimlich valve, which allows the patient to remain ambulatory. C, CT scan shows 7-French chest tube (arrow) placed by trocar method. Variances in technique and skill are at least partially responsible for the wide range. This is a procedure (test) where a tiny sample of tissue (biopsy) is taken from lungs for analysis. Chest tube placement is indicated if a postbiopsy pneumothorax becomes symptomatic or continues to enlarge on chest radio graphs, usually obtained 1 and 3 hours after the procedure at our institution. The chest tube insertion rate is much lower, ranging from 1% to 14.2% of patients [1–4]. Oxygen is administered through a nasal cannula during and after the procedure to speed the resorption of the pneumothorax if one does develop [9]. More serious complications A puncture of the lung resulting in a small air leak (or pneumothorax) can occur when biopsies are taken. OpenUrl PubMed Web of Science • Minor complications are common in CT-guided lung biopsy • Major complication rate is low in CT-guided lung biopsy • CT-guided lung biopsy complications occur more often in core biopsy than FNA • Major complication rate is similar in core biopsy and FNA • Risk factors for FNA are larger needle diameter, smaller lesion size. The CNB procedure alone will not suffice. Results of this type of biopsy help doctors … Address correspondence to C. C. Wu ([email protected]org). Core Roll Preparations and the Pathologist as Consultant. A lung needle biopsy is a procedure that removes a small amount of lung tissue from the body for analysis. Background: To investigate puncture skills and complications prevention in ultrasound-guided percutaneous needle biopsy for peripheral lung lesions. Small lesions less than 15 mm remain very challenging for radiologists. Furthermore, the presence of a pleural effusion may hinder the detection of bleeding. In cases in which the lesion is in the chest wall, mediastinum, pleura, or subpleural lung and no aerated lung is traversed by the biopsy needle, the likelihood of pneumothorax is minimal [4].
