We report a case of a young morbidly obese patient who underwent sleeve gastrectomy that was complicated by a postoperative leak at the level of the gastroesophageal junction. A covered esophageal stent was placed endoscopically to treat the leak. The pa-tient developed massive upper gastrointestinal bleeding secondary to the erosion of the stent into an aberrant retroesophageal right subclavian artery twelve days after stent placement. She was ultimately treated by endovascular stenting of the aberrant right subclavian artery followed by thoracotomy and esophageal repair over a T-tube. This case report highlights the multidis-ciplinary approach needed to diagnose and managesuch a devastating complication. It also emphasizes the need for imaging studies prior to stent deployment to delineate the vascular anatomy and rule out the possi-bility of such an anomaly in view of the growing popu-larity of esophageal stents, especially in the setting of a leak.展开更多

That systemic artery is usually large, originating from the thoracic aorta or the abdominal aorta and its upper branches. We describe a case of ILS where a large systemic artery coming up from below the diaphragm is formed by the convergence of many very small serpiginous arteries coming up from the area of the celiac trunk and common hepatic artery: a kind of “rete mirabile”. This peculiar morphology was not described before.展开更多

This report presented our surgical experience for pediatric cases of intralobar pulmonary sequestration in our institute. Methods: Between 2002 and 2014, 30 pediatric patients with intralobar pulmonary sequestration underwent lobectomy. The clinical characteristics of patients were retrospectively analyzed using medical records and imaging data. Results: The median age at operation was 23 months. The sequestered lung was situated in the right lower lung in 15 cases and in the left lower lung in 15 cases. Eight cases were prenatally diagnosed by fetal ultrasound and magnetic resonance imaging. One aberrant artery was seen in 26 cases and two aberrant arteries in 4 cases. The drainage vein from the sequestered lung was: 1) the pulmonary vein in 27 cases;2) the inferior vena cava in 1 case;and 3) the azygos vein and the pulmonary vein in 2 cases. All patients underwent lower lobectomy of the affected side without postoperative early and long-term complications. Conclusion: Due to the increased rate of prenatal diagnoses, the age at operation has decreased. With respect to safety, it is vital to ascertain the number of aberrant arteries and the venous drainage route before lobectomy.展开更多
