Outcome Measures

Primary Outcomes (1)

  • Pneumothorax incidence

    Development of pneumothorax after biopsy as a complication

    first 24 hours

Secondary Outcomes (1)

  • Chest tube placement incidence

    Immediately after procedure

Study Arms (2)

A

The patients who underwent tru-cut biopsy with the coaxial technique and applied an autologous blood patch.

Other: Autologous blood patchOther: Percutaneous transthoracic biopsy

B

The patients whose true-cut biopsy with coaxial technique was taken and autologous blood patch was not applied.

Other: Percutaneous transthoracic biopsy

Interventions

Approximately 3-4 pieces were taken with the 18 G core biopsy needle until sufficient tissue was obtained. In the autologous blood patch technique, approximately 6-7 ml of blood was taken from the patient with a 10 ml syringe before the procedure. By attaching a 3-way tap to the injector from which the blood is drawn, blood is drawn into a second injector to ensure that the clotted blood is dispersed and homogenized. The prepared autologous blood patch was given through the coaxial needle (approximately 1 ml of autologous blood patch was applied for every 1 cm when the coaxial needle was withdrawn) and the tract formed by the biopsy needle in the parenchyma, pleura, and under the skin was closed with the patient's autologous blood.

A

After determining the lung lobe where the lesion was observed, axial CT images of 5 mm cross-section thickness were obtained so that the upper and lower parts of it could be visualized. After ruling the entry site in the skin, antisepsis and local anesthesia were performed. The coaxial system (17 G) was cautiously advanced and CT images were continuously evaluated to confirm entrance into the lesion. Biopsy was taken and after sufficient tissue samples were taken at the last stage of the biopsy procedure, control CT imaging, including the whole lung, was performed to evaluate complications. The presences of pneumothorax were noted.

Sampling MethodProbability Sample
Study Population

The study comprised 240 patients who received a transthoracic lung biopsy using the percutaneous coaxial technique at Trakya University Faculty of Medicine, Department of Radiology, Interventional Radiology unit, between January 1, 2015 and September 14, 2020.

You may qualify if:

  • Patients older than 18 years
  • Patients who underwent percutaneous transthoracic tru cut biopsy
  • Patients undergoing interventional procedures by radiologists with equal experience
  • Patients who were able to obtain sufficient samples with the applied biopsy (technical success of percutaneous transthoracic biopsy)
  • Patients whose medical records are fully accessible and whose data are reliable

You may not qualify if:

  • Patients whose laboratory bleeding parameters are not suitable for the procedure (platelets\<100000/mm3, INR\>1.5)
  • Pregnancy
  • Patients with increased risk of pneumothorax due to other etiologies (bulla, blep, chronic obstructive pulmonary disease, cystic fibrosis)
  • Patients receiving anticoagulant antiplatelet therapy
  • Patients with persistent cough
  • Patients with a history of recent lung travma, pneumothorax, hemoptysis or pulmonary hemorrhage
  • Patients with severe psychiatric diseases such as psychosis or dementia that limit cooperation with the patient
  • Patients with anatomic deformity (advanced scoliosis and kyphotic patients. Patients with pectus carinatum and pectus excavatum-like chest deformity)
  • Patients for whom tru cut biopsy is absolutely and relative contraindicated (suspected hydatid cyst or known vascular lesions such as arteriovenous malformation, pulmonary varicose, severe obstructive pulmonary disease, coagulopathy, moderate to severe pulmonary hypertension, ventilator dependence, unilateral pneumectomy)
  • Patients allergic to local anesthetic drug used for skin and subcutaneous tissue anesthesia
  • Patients who do not want to participate
