Abstract

Background: Pulmonary sequestration (PS) is a form of congenital pulmonary malformation that is generally diagnosed in childhood or adolescence and usually resected when diagnosed. We aim to identify the clinical presentation and course of patients diagnosed to have PS during adulthood. Methods: Using a computer-assisted search of Mayo clinic medical records, we identified adult patients with PS diagnosed between 1997 and 2016. Clinical and radiological data were collected including postoperative course for those who underwent surgical resection. Results: We identified 32 adult patients with PS; median age at diagnosis was 42years (IQR 28-53); 17 patients (53%) were men. The median sequestration size was 6.6cm (IQR 4.4-9.3). The type of sequestration was intralobar in 81% and extralobar in 19%. The most common location was left lower lobe posteromedially (56%). Forty-seven percent of the patients presented with no relevant symptoms. The most common radiographic finding was mass/consolidation in 61% and the most common feeding artery origin was the thoracic aorta (54%). Surgical resection was performed in 18 patients (56%) and postoperative complication was reported in 5 patients (28%). There was no surgical mortality. Median duration of follow-up after diagnosis for unresected cases, most of whom were asymptomatic, was 19months (IQR 4-26) with no complications related to the PS reported. Conclusions: Nearly one-half of adult patients with PS present with no relevant symptoms. The decision regarding surgical resection needs to weigh various factors including clinical manifestations related to PS, risk of surgical complications, comorbidities, and individual patient preferences.
