“…ELS is a rare congenital anomaly, representing 25% of all pulmonary sequestrations, which have an overall estimated incidence of only 0.15%-1.7% [ 1 , 8 ]. Unlike ILS, which are contained within the visceral pleura of the normal lung, ELS are invested in their own pleural lining, and lack the ligamentous attachments of the normal lung.…”

“…Although typically arising from the lung bud, ELS can arise within the abdomen, diaphragm, or pericardium. ELS is more often left sided and is usually fed by a single systemic artery, typically arising from the thoracic or abdominal aorta and draining into the systemic venous system [1] .…”

“…ELS is commonly detected antenatally, especially given its relatively high association (50%-60%) with other congenital anomalies, including congenital diaphragmatic hernia, congenital heart disease, and congenital pulmonary airway malformation [ 1 , 2 ]. After birth, infants with ELS may experience respiratory distress, hemorrhage, malabsorption, or high-output congestive heart failure secondary to shunting [1] . However, asymptomatic cases may remain undetected until discovered incidentally [3] .…”

“…However, asymptomatic cases may remain undetected until discovered incidentally [3] . ELS symptomatic in adulthood have been reported to cause massive hemothorax or recurrent massive pleural effusion [1] . One uncommon complication of ELS is torsion on its vascular pedicle, resulting in infarction of the sequestration, as we describe in this case report.…”

Extralobar pulmonary sequestration is a rare congenital pulmonary malformation that may present early in life or remain asymptomatic. Here we present a case of torsion of an extralobar pulmonary sequestration on its vascular pedicle. Although the patient's initial symptomatology suggested intraabdominal pathology, the correct preoperative diagnosis was determined in large part by the lesion's MRI characteristics, which strongly suggested tissue infarction.

“…Multi-detector computed tomography (CT) plays a key role in the diagnosis of PS and surgical planning. PS has a variety of appearances in CT images including consolidation, mass, or air/ uid-lled cystic or multicystic lesion [1]. Once a PS is diagnosed, resection is suggested, regardless of the symptoms.…”

BackgroundPulmonary sequestration (PS) is a rare lesion with independent blood supply from an anomalous systemic artery. A timely resection is considered the best treatment for PS, but the optimal approach is controversial. Three-dimensional computed tomography angiography (3D-CTA) has been widely utilized for precise thoracic surgery. This study aimed to investigate the safety of uniportal video-assisted thoracoscopic surgery (VATS) for PS assisted with preoperative 3D-CTA. MethodsThe data of patents with PS who underwent VATS anatomic lung resection between April 2011 and May 2021 in a single centre were retrospectively reviewed. They were divided into uniportal and tow-port groups according to the initial surgical plan. The perioperative parameters including the incidence of conversion to open thoracotomy, operation time, blood loss, complications and chest tube duration were analyzed. ResultsTwenty consecutive patients (9 in uniportal group and 11 in two-port group) underwent VATS for PS, including 12 female and 8 male patients, with a mean age of 45 years old (range, 24-60 years). Nine cases demonstrated recurrent febrile, cough, or hemoptysis; whereas the other 11 patients were asymptomatic. The 3D-CTA was utilized for all patients in the uniportal group and 1 patient in the two-port group. Eighteen (90.0%) intralobar and 2 extralobar PS were confirmed; and 18 (90.0%) lesions were located in the left thorax. The feeding vessels originated from the thoracic aorta in 16 patients (80.0%), the abdominal aorta in 3 (15.0%) and the inferior phrenic artery in 1 patient (5.0%). Thirteen lobectomies, 5 segmentectomies and 2 mass excisions were performed. There was no major bleeding or 30-day mortality. No conversion was needed in the uniportal group; whereas 6 (54.5%) conversions (4 to multiple-port and 2 to thoracotomy) occurred in the two-port group, indicating a significant difference (P=0.008). In addition, the operation time in the uniportal VATS group was significantly shorter than those in the two-port VATS group ([110.6 ± 25.5] min vs. [148.6 ± 42.1] min, P = 0.029). The other perioperative variables were similar between the two groups. During the follow-up of 5-75 months, no recurrence of hemoptysis was recorded. ConclusionPreoperative 3D-CTA facilitates the safe performance of uniportal VATS anatomic lung resection for PS, which might be associated with shorter operation time and lower conversion to thoracotomy.

Key Clinical MessagePulmonary sequestration is a congenital malformation of lung development in which part of the lung tissue is separated from the normal lung during the embryonic phase and develops separately and receives blood supply from an aberrant systemic artery forming a nonrespiratory mass. In brief, early in embryonic development, certain tissues that should have atrophied and been gradually absorbed are left behind due to impairment of the atrophy process and form anomalous branches of the aorta, which pull parts of the lung tissue, isolating them from normal lung tissue and bronchi, and thus forming separate lung tissue. According to the relationship of the mass to the pleural covering, pulmonary sequestration can be divided into two types, intralobar pulmonary sequestration (ILS) and extralobar pulmonary sequestration (ELS), of which approximately 75% of cases are ILS, but ELS is less common. Symptoms are not obvious in either type, making diagnosis and differential diagnosis more difficult. Here we report a 33‐year‐old patient with only insignificant abdominal distension who was eventually diagnosed with retroperitoneal ELS.
