Abstract :

 

INTRODUCTION:

CT guided transthoracic biopsy/FNAC is integral in the diagnosis and treatment of many thoracic diseases, and is an important alternative to more invasive surgical procedures. Complications include pneumothorax, haemoptysis, haemothorax, infection, and air embolism, with the most common complication as pneumothorax.

 

AIMS AND OBJECTIVES:

To know the incidence and risk factors of pneumothorax in patients undergoing CT guided transthoracic biopsy/FNAC at our institute.

MATERIAL AND METHODS:

Retrospective analysis of 100 patients presented with lung and mediastinal mass lesions who underwent CT guided transthoracic biopsy/FNAC was done. Out of 100 cases, male patients were 75 and female patients were 25 with maximum number of cases in age group of above 60 years and 40 to 60 years respectively. Out of 100 cases, 93 patients presented with lung lesions and 7 patients with mediastinal lesions. Based on the size of lesion, number of cases with size less than or equal to 3 cm were 12, between 3–6 cm were 39 and above 6 cm were 49.

RESULTS:

Out of 100 cases, 22 patients developed pneumothorax post procedure and all were those presented with lung lesions. No patient presented with mediastinal lesion developed pneumothorax. Percentage of cases that developed pneumothorax with size of the lesion less than 3 cm were 33 %, between 3–6 cm were 18 % and above 6 cm were 22.4 %. Maximum number of cases that developed pneumothorax were in elderly age group and in lesions that are in close contact with the chest wall.

 

 

CONCLUSION:

·         Overall incidence of pneumothorax encountered in our study is around 22% 

·         Risk factors associated with pneumothorax are categorized as patient factors, lesion factors and technical factors.  Among patient factors; elderly age group, history of smoking and known COPD cases; Among lesion factors;  smaller lesions(<3cm), increased needle course in the lung ; Among technical factors; increased pleural punctures in single biopsy and repeat biopsies are associated with higher risk of developing pneumothorax.
