Nonrecurrence of the inferior laryngeal nerve always results from a vascular anomaly during embryonic development of the aortic arches. The nonrecurrent inferior laryngeal nerve is important clinically for two reasons, it is vulnerable during thyroid surgery and it is associated with difficulty in swallowing. It can be suspected preoperatively from signs associated with the vascular anomaly : dysphagea, thoracic x-ray images showing evidence of retroesophageal subclavian artery, or situs inversus viscerum. If such signs are noted, a barium swallow test and chest computed tomography are justified. We experienced a case of Rt. nonrecurrent inferior laryngeal nerve, which is diagnosed thyroid papillary carcinoma.

Introduction: Surgical treatment of subclavian artery (SA) injury is challenging because approaching the lesion directly and clamping the proximal artery is difficult. This can be overcome by using an endovascular technique. Case 1: A 37-year-old male was drawn into the concrete mixer truck. He had a right SA injury with multiple traumatic injuries: an open fracture of the right leg with posterior tibial artery (PTA) injury, a right hemothorax, and fractures of the clavicle, scapula, ribs, cervical spine and nasal bone. The injury severity score (ISS) was 27. Computed tomography (CT) showed a 30-mm-length thrombotic occlusion in the right SA, which was 15 mm distal to the vertebral artery (VA). A self-expandable stent($8mm{\times}40mm$ in size) was deployed through the right femoral artery while preserving VA flow, and the radial pulse was palpable after deployment. Other operations were performed sequentially. He had a viable right arm during a 13-month follow-up period. Case 2: A 25-year-old male was admitted to our hospital due to a motorcycle accident. The ISS was 34 because of a hemothorax and open fractures of the mandible and the left hand. Intraoperative angiography was done through a right femoral artery puncture. Contrast extravasation of the SA was detected just outside the left rib cage. After balloon catheter had been inflated just proximal to the bleeding site, direct surgical exploration was performed through infraclavicular skin incision. The transected SA was identified, and an interposition graft was performed using a saphenous vein graft. Other operations were performed sequentially. He had a viable left arm during a 15-month follow-up period. Conclusion: The challenge of repairing an SA injury can be overcome by using an endovascular approach.

Objective: To report the authors' experience in performing thoracic endovascular aortic repair (TEVAR) for zone 2 lesions after traumatic aortic injury (TAI). Materials and Methods: This retrospective review included 10 patients who underwent zone 2 TEVAR after identification of aortic isthmus injury by CT angiography (CTA) upon arrival at the emergency room of a regional trauma center from 2016 to 2019. Patients were classified into two groups: those who underwent left subclavian artery (LSA) embolization concurrently with the main TEVAR procedure, and those in whom LSA embolization was not performed during the main procedure, but was planned as a bailout treatment if type II endoleak was noted on follow-up CTA images. Pre-procedural and procedure-related factors and post-procedure prognosis were compared between the groups. Results: There were no differences in pre-procedural factors, occurrence of endoleaks, and post-procedure prognosis (including mortality) between patients in the two groups. The duration of the procedure was shorter in the non-LSA embolization group (61 minutes vs. 27 minutes, p = 0.012). During follow-up, type II endoleak did not occur in either group. Conclusion: Delaying preventative LSA embolization until stabilization of the patient would be desirable when performing zone 2 TEVAR for TAI, in the absence of endoleak on the completion aortography image taken after complete deployment of the stent graft.

Background: There has been controversy over the prevalence of recoarctation in infants treated by subclavian flap aortoplasty(SFA) for coarctation of the aorta. To assess the rate of recurrence of coarctation after SFA, we reviewed the surgical results of SFA in infants with coarctation of the aorta. Material and method: Between 1986 and 1998, a total of 25 patients less than 1 year of age(12 neonates and 13 infants) underwent SFA for aortic coarctation. Age at operation was 3.0$\pm$3.0 months(mean $\pm$ standard deviation); mean weight was 5.0$\pm$1.4kg. Classic SFA was performed in 20 patients, reversed SFA in 2 patients, subclavian artery reimplantation in 2 patients and the combined resection-flap aortoplasty in one. Result: The aortic clamping time ranged from 20 to 88 minutes(mean 35.8 minutes). There were one operative death and two late deaths. There was no case of paraplegia or left arm ischemia in complications. Twenty-one(84%) of 24 hospital survivors were followed for 26.0$\pm$24.0 months. The risk of recoarctation in neonates(33.3%) was a little greater than infants(25.0%) without statistical significance. Conclusion: This study revealed that SFA resulted a relatively high incidence of recarctation in infants. It is desirable to select other methods of surgical treatment(combined resection-flap aortoplasty, extended end-to-end repair etc.) for severe isthmic coarctation or hypoplasia of the distal aortic arch in infants, instead of choosing SFA indiscriminately.

A patient was 29 year old house wife who was admitted to the Yonsei University Medical Center on 6 th of Nov., in 1970, with chief complaints of complete loss of bilateral visual acuity, generalized weakness, frequent palpitations, claudication of masseter muscles and intermittent fainting. These symptoms were developed 5 years prior to admission. Physical finding on admission revealed complete loss of bilateral visual acuity, absence of both radial and carotid pulse, but there was good femoral and popliteal pulse. She couldn't open her mouth as she desired and had weakness of mastication. Radiological findings of plane chest PA were not significant. Aortogram(Cineangiogram) showed non-visualization of both carotid and subclavian arteries. It showed only innominate and interal mammary artery preoperatively. The operative findings were as follows: There were complete obliterative changes in both common carotid and subclavian arteries, and periarteritis in the innominate artery. Tube Dacron Prosthesis Bypass with V-arm between innominate artery and both common carotid arteries was performed after thromboendarterectomy. Histopathological finding of the thromboend arterectomy specimen was compatible with pulseless disease, which showed marked fibrous thickening of intima and a diffuse inflammatory cell infiltration of the whole layers. Her postopererative course was uneventful. Follow up aortogram(Cineangiogram) was taken on 11th postoperative day, which revealed both common carotid arteries patent. Her preoperative Subjective symtoms disappeared remarkably, such as her visual acuity improved much, fainting and vertigo disappeared completely and she can go to bath room without difficulty and help. Another patient was 34 year old house wife who was admitted on August, 1964 with chief complaints of frequent fainting and progresive visual loss. She was operated only thromboendarterectomy of both common carotid arteries. Postoperative course was smooth and subjective symptoms were disappeared.

Patients with anomalous connection of the left coronary artery to the pulmonary artery are at risk for myocardial infarction, and early or sudden death. Between 1986 to 1992, a total of 4 of these patients underwent surgical intervention with various operative techniques at our institution. Age at operation ranged from 2 months to 43 years. Three infant patients had congestive heart failure, 2 of them had mitral regurgitaion, and 1 had ST-T change on elctrocardiogram. Operative techniques included direct coronary artery transfer to the aorta[n=2], intrapulmonary tunnel from the aortopulmonary window[n=1], coronary artery bypass using saphenous vein[n=1]. One deaths occured at 2 weeks after direct coronary arterial transfer due to respiratory failure caused by Respiratory Syncitial virus pneumonia. Supravalvar pulmoanry stenosis occured after intrapulmoanry tunnel. We recommend direct aortic implatation of the anomalous coronary artery at the time of diagnosis. Intrapulmonary tunnel from aortopulmonary window or subclavian-coronary anastomosis could be alternatives in whom aortic implantation is not feasible anatomically.
