Giant Pulmonary Herniation: A Late and Rare Complication of Minimally Invasive Lung Biopsy for Interstitial Lung Disease

Abstract

Pulmonary herniation is the protrusion of the lung parenchyma beyond the normal limits of the thoracic cavity. It is a rare entity. In general, the defect in the chest wall is accompanied by increased intrathoracic pressures in the formation mechanism. Usually the cause is blunt-penetrating thoracic trauma, violent cough or previous thoracic surgery with insufficient closure of the chest wall. We report a case with giant pulmonary herniation that developed four years after biopsy in a patient diagnosed with usual interstitial pneumonia by VATS. Although this is a very rare condition in the literature, one of the late and rare complications of diagnostic pulmonary resections with awake VATS may be caused giant pulmonary herniation
