We examined retrospectively the characteristics and the outcomes of intralobar sequestrations (ILS). We reviewed data we obtained from the medical records of patients with ILS who underwent surgery at Laennec, Georges Pompidou European, and Amiens South Hospital. From 1985 to 2010, 26 consecutive adults patients underwent surgery for ILS. There were 14 males and 12 females. The average age was 37.3 years. The ILS was right-sided in 11 patients (42.3%) and left-sided in 15 patients (57.7%). A systemic artery supply was found during the preoperative period in 11. Surgery consisted of lobectomy (n=20), bilobectomy (n=1), segmentectomy (n=4), and pneumonectomy (n=1). There were no postoperative deaths, and the postoperative course was uneventful in 20 patients. All patients were alive and faring well at long-term follow-up (mean follow-up 36.5 ± 7.2 months). Surgery consisted of lobectomy in most cases. The arterial supply came from the descending thoracic and abdominal aorta. Hemoptysis and/or recurrent infections were present in 14/26 (54%) of patients. These are the same symptoms as those leading to the diagnosis of bronchectasis. This suggests, for similar reasons, that ILS in adults should be nosologically very similar to acquired lesions, such as bronchectasis.
