  • Pulmonary sequestration is an uncommon congenital pulmonary malformation characterized by presence of nonfunctioning lung tissue which receives its blood supply mostly from the anomalous systemic arteries - descending thoracic aorta or abdominal aorta, subclavian artery, innominated artery and internal mammary artery, etc. In our country, 39 cases were reported previously. The patient was a 40 years old woman and admitted due to productive cough for 1 year. The chest X-ray and chest C-T showed a dense mass containing a large cavity with air-fluid level and multiple radiolucent cysts in the right lower lung field. On the operative field, we could identify an aberrant large artery [ $\phi$7mm which arose directly from the descending thoracic aorta at eighth thoracic spinal level and fed the sequestrated portion of the right lower lobe. The aberrant artery was double ligation after division. Only sequestrated lobe on the superolateral lesion of the right lower lobe was resected because of nonseparated lobes in all the right lobes. An abnormal vein and bronchiole were ligated with black silk. The patient`s postoperative course was unevenful.

  • A 3-month-old intact male Lakeland terrier was presented with recurring regurgitation after removing cervical esophageal foreign body by endoscopy. Blood and urine analysis, radiography, ultrasonography, fluoroscopic esophagography, computed tomographic angiography (CTA) were performed. In radiography and fluoroscopic esophagography, vascular ring anomaly was considered as the primary cause of megaesophagus, and CTA with gas-inflation of the esophagus was performed. Compressed esophagus, persistent right aortic arch (PRAA), aberrant left subclavian artery (LSA), and a venous structure which was confirmed in surgery to be incomplete type persistent left cranial vena cava (PLCVC) connected with the left side azygos vein were observed. Left deviation of the trachea was also revealed in CT, which implies the compression by left ligamentum arteriosum. Therefore, type 3 PRAA with left ligamentum arteriosum and aberrant LSA, was considered as a prior differential diagnosis. Surgical repair was performed and the clinical signs improved. This report describes CTA characteristics of combination of PRAA with aberrant LSA, incomplete PLCVC and Lt. azygos vein in a dog. Although not every vascular anomaly does induce clinical sign, some types can complicate the surgical procedure, and cause clinical signs. Therefore, thorough evaluation of vascular anomalies in the thorax is important, and CTA is a useful method in identifying multiple vascular anomalies in dogs.

  • Background and Objectives: The nonrecurrent laryngeal nerve(NRLN) is exceedingly rare nerve anomaly that is associated with developmentally aberrant subclavian artery. The presence of NRLN is associated with an increased risk of vocal cord palsy in thyroid surgery. The purpose of this study is to investigate its prevalence, associated vascular anomaly and necessity of recognizing its possibility for prevention of intraoperative nerve damage. Materials and Methods: Between January 2004 and December 2006, 583 thyroidectomy were performed at our hospital. Of these cases, 529 cases(90.7%) were checked preoperative neck CT. Results: Patients with preopreative neck CT, 6 cases show the retroesophageal abberant right subclavian artery that arising directly form the aortic arch. 5 cases of these 6 cases(5/6, 83.3%) and of 583 patients(5/583, 0.8%) performed thyroid surgery were identified NRLN per-operatively. All of them are identified on the right side. There were 4 women and 1 man. In all cases, there were no clinical symptoms. I case was performed only left hemithyroidectomy, so we cannot identified NRLN. No vocal cord palsy was observed. Conclusion: It is possible to predict NRLN from preoperative neck CT. When NRLN is suspected, careful, complete dissection of the nerve is always advocated. These process can reduce the operative morbidity.

  • Developmental anomalies of the aortic arch, commonly known as vascular rings, are relatively rare congenital vascular anomalies which can compress the trachea and esophagus. We have presented six patients with surgically treated vascular rings at Seoul National University Hospital during the period June 1970 through May 1984. Two patients had double aortic arches and four patients had right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. Four patients had symptoms relating vascular ring and two patients were detected incidentally during diagnostic evaluation of symptomatic intracardiac defects. Associated congenital malformations were seen in four patients. The operative approach was through left thoracotomy in three patients and median sternotomy in remaining three patients associated with congenital cardiac defects. There were no postoperative deaths with excellent result in preoperative symptomatic patients. To our knowledge, successful surgical repair of vascular ring has been reported only once in the Korean literature.

  • Genetic ultrasonography refers to the evaluation of risk of chromosomal abnormalities via various soft sonographic markers. Although the maternal serum test is the primary screening method for chromosomal abnormalities, genetic ultrasonography is also widely used and can help increase detection rates. To date, many soft markers, including choroid plexus cysts, echogenic intracardiac foci, mild ventriculomegaly, nuchal fold thickening, echogenic bowel, mild pyelectasis, short femur and humerus length, and absent or hypoplastic nasal bone, have been reported. An aberrant right subclavian artery was the most novel soft marker introduced. Because these soft markers involve diverse relative risks of chromosomal abnormalities, it is difficult to apply them to clinical practice. To optimize the efficacy of genetic ultrasonography, it is important to understand the precise relative risks of chromosomal abnormalities innumerous soft markers and integrate these risks with each other and the results of maternal serum screening.

  • Retroesophageal aortic arch, in which the aortic arch crosses the midline behind the esophagus to the contralateral side, is a rare form of vascular anomaly. The complete form may cause symptoms by compressing the esophagus or the trachea and need a surgical intervention. We report a rare case of a hypoplastic left heart syndrome variant with the left retroesophageal circumflex aortic arch in which the left aortic arch, retroesophageal circumflex aorta, and the right descending aorta with the aberrant right subclavian artery encircle the esophagus completely, thus causing central bronchial compression. Bilateral pulmonary artery banding and subsequent modified Norwood procedure with extensive mobilization and creation of the neo-aorta were performed. As a result of the successful translocation of the aorta, the airway compression was relieved. The patient underwent the second-stage operation and is doing well currently.

  • Background: We aimed to assess the clinical outcomes of patients who underwent surgical repair of Kommerell diverticulum (KD) with individualized surgical methods. Methods: A retrospective analysis was performed of adult patients (aged ≥17 years) who underwent surgery to treat KD between June 2008 and October 2019. Results: Nine patients (median age, 45 years; range, 19-67 years; 7 men) underwent surgical repair. The indications for surgical therapy were acute aortic dissection in 2 patients, the presence of compressive symptoms due to dilated KD in 4 patients, and aneurysm growth in 3 patients. Various surgical techniques were used: (1) resection of the diverticulum stump and revascularization of the aberrant subclavian artery (n=3), (2) one-stage total-arch replacement including the diverticulum segment (n=3), and (3) hybrid repair (n=3). Early mortality occurred in 1 case of hybrid repair. Transient paraparesis occurred in a patient who underwent total arch repair as part of complicated acute aortic dissection. During follow-up (median duration, 30 months; range, 7-130 months), no late death or associated aortic complications were documented. All survivors were free from symptoms and had no abnormal findings on follow-up computed tomography. Conclusion: With a customized surgical approach and appropriate consideration of patient-specific anatomy and associated comorbidities, KD can be repaired with favorable outcomes.
