The role of 3-dimensional reconstruction imaging in bronchopulmonary sequestration.

Bronchopulmonary sequestration is a congenital abnormality characterized by non-functioning lung tissue, abnormal connection with the tracheobronchial tree and anomalous systemic arterial supply. Although considered a rare phenomenon presenting early in life, sequestration may also present with recurrent chest infections in late adulthood. Additionally, bronchopulmonary sequestration may rarely be incidentally encountered during thoracic surgery. Several subtypes exist including intralobar, extralobar and hybrid bronchopulmonary sequestration (congenital pulmonary artery malformation). Surgical resection is curative and serves as the treatment of choice for symptomatic patients. Radiological imaging prior to surgery is essential in these patients because the arterial supply may be anatomically complex, and aberrant artery branches are common. Utilization of virtual 3-dimensional remodelling and computed tomography reconstruction imaging can not only establish a diagnosis of bronchopulmonary sequestration but can also optimize preoperative planning. This approach will ultimately prove useful in anticipating surgically challenging steps and avoiding unnecessary intraoperative complications. We present a video tutorial on the role of 3-dimensional reconstruction imaging in bronchopulmonary sequestration and a step-by-step guide for performing a right robotic-assisted surgical resection of an S2 hybrid bronchopulmonary sequestrated segment. This case is followed by a second case of intralobar bronchopulmonary sequestration encountered incidentally during thoracic surgery.
