저자들은 출생 후 호흡기 증상이 지속되어 오던 여아가 respiratory syncytial virus와 b형 헤모필루스 인플루엔자균에 의한 하기도 감염에 이환되면서 생후 4개월에 혈관륜으로 진단된 1예를 보고하는 바이다. 환아는 출생 후 협착음과 천명음 등의 잦은 호흡기 증상을 보였고, 3개월에 호흡 곤란을 주소로 입원하였으며 respiratory syncytial virus에 의한 세기관지염으로 치료받고 호전되었다. 퇴원 후 증상이 다시 악화되어 재입원 하였으며 b형 헤모필루스 인플루엔자균에 의한 기관염 및 폐렴이 확인되었고, 치료를 위해 기관내 튜브에 도관 삽입을 시도하였을 때 하부 기도에서 저항감이 감지되어 기도 부위의 해부학적 기형을 의심하게 되었다. 3차원 흉부 단층 촬영에서 이중 대동맥궁으로 인한 혈관륜이 확인되었고, 교정 수술을 시행한 후 좋은 경과를 보이고 있다.

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.

배경: 혈관륜은 대동맥궁의 드문 기형으로 저자들이 12년 간 경험한 16예의 수술 결과를 정리하여 그 경험을 공유하고자 한다. 대상 및 방법: 1995년 11월부터 2007년 9월까지 혈관륜으로 수술을 받은 16명을 대상으로 하여 이중 대동맥궁(n=5), 우측 대동맥궁-동맥관 인대(n=7), 폐동맥 슬링(n=4)의 세 가지 그룹으로 분류하였다. 각 그룹의 수술 당시 평균 연령은 이중 대동맥궁 그룹에서 $5.7{\pm}5.5$세, 우측 대동맥궁-동맥관 인대 그룹에서 $6.1{\pm}13.4$세, 폐동맥 슬링 그룹에서 $2.9{\pm}2.6$세였다. 우측 대동맥궁-동맥관 인대 그룹의 71% (n=5)에서 Kommerell 게실이 동반되어 있었다. 기관 협착은 이중 대동맥궁 그룹 중 2예(40%), 우측 대동맥궁-동맥관 인대 그룹 중 2예(28.6%), 폐동맥 슬링 그룹 중 4예 (100%)에서 동반되어 있었다. 함께 진단된 심장 기형은 전체의 50% (n=8)였다. 결과: 사망한 예는 없었고, 증상 재발 및 문합부 협착 등으로 재수술을 시행한 예도 없었다. 평균 재원 기간은 $27.1{\pm}38.2$일이었다. 결론: 혈관륜은 드문 질환이지만 수술적 교정이 필요하므로, 원인이 명확하지 않은 호흡기 증상이 반복될 경우에는 심초음파 등으로 반드시 확인해 보아야 하며, 수술 전후의 전산화 단층촬영 및 기관지 내시경은 기도 협착 및 주변 해부학적 구조와의 관계 평가에 유용하게 이용할 수 있다.

A 6-month-old, female poodle presented with a three-month history of persistent regurgitation immediately after eating. On physical examination, the patient was emaciated and dehydrated. Thoracic radiography showed ventral displacement of the trachea and increased radiopacity in the mediastinum, cranial to the heart base. A severely dilated esophagus was identified cranial to the heart on esophagram. Computed tomography (CT) revealed the esophagus was filled with gas, fluid and a little of contrast and dilated from caudo-cervical to cranio-thoracic part. The esophageal diameter was markedly decreased at the heart base. In addition, the trachea was displaced to the left-ventral side of the right aortic trunk and an aberrant left subclavian artery originating from the aorta was identified. There was no evidence of abdominal vascular anomaly. Based on diagnostic imaging, persistent right aortic arch (PRAA) with an aberrant left subclavian artery was diagnosed. The patient did not undergo surgery and died at 15 days after diagnosis. This report describes imaging diagnosis, including CT and radiography in a weaned dog with regurgitation due to esophageal obstruction by PRAA. When PRAA is suspected and conventional radiography or contrast study is insufficient for diagnosis, CT may be helpful for diagnosing PRAA.

Pulmonary artery sling is a rare congenital cardiac anomaly, in which the left pulmonary artery originates from the right pulmonary artery and courses leftward between the trachea and the esophagus. Tetralogy of Fallot associated with pulmonary artery sling is even rarer, and only a few cases have been reported in the literature. We present a case of tetralogy of Fallot associated with pulmonary artery sling that was repaired successfully.

This paper reports the clinical findings and surgical treatment of feline right patent ductus arteriosus (RPDA) with a left aortic arch. A two-month-old female Maine Coon was referred for an investigation of regurgitation after weaning. RPDA with a left aortic arch was diagnosed based on the echocardiographic and computed tomography (CT) findings. A right-fourth intercostal thoracotomy was found to be an appropriate approach to the duct. Preoperative diagnosis is crucial and diagnostic imaging, including radiography, echocardiography, and cardiac CT examination, is essential for determining if the aortic arch is right or left.
