Sukki Cho, In Hag Song
This study determined the feasibility of the cuff technique for small-caliber vascular grafts in a rat model. A graft was implanted with the cuff technique or suture technique in a 1-cm segment of the abdominal aorta in 12 rats. The mean aortic clamp time was 29 minutes with the cuff technique and 44 minutes with the suture technique; the cuff technique was significantly shorter. Abdominal angiography at 1 week after implantation showed no significant stenosis in 9 rats, focal stenosis of the mid-portion of the graft in 1 rat with each technique, and total occlusion of the graft in 1 rat with the suture technique...

Hemangioendothelioma is a rare vascular tumor with involvement of the liver, brain, long bones, and lung. Among the 6 histological subtypes, epithelioid hemangioendothelioma (EHE) is the most aggressive. Its occurrence in the mediastinum is quite rare, and very few cases have been documented. The reported cases in the literature have described difficulties in the preoperative diagnosis due to the unusual histological appearance of the tumor. Immunohistochemistry remains the mainstay for a definitive diagnosis...

A solitary fibrous tumor (SFT) is a mesenchymal fibroblastic tumor inside the pleura, for which complete surgical resection is the standard treatment. For large SFTs, preoperative identification of tumor-feeding vessels using angiography is important for achieving complete resection without unexpected operative bleeding. Extensive adhesions can make resection difficult in a limited operative window, and pulmonary resection may be required to achieve complete SFT resection. Herein, we report successful resection of a large pleural SFT in a 39-year-old man without any complications using a 2-stage approach, in which ligation of the feeding vessels through small another operative window was the first step...

Primary pulmonary meningioma is a rare disease, and chordoid meningioma is an uncommon variant of meningioma in the central nervous system (CNS) with a high recurrence rate. We report a case of primary pulmonary chordoid meningioma that presented as a solitary pulmonary nodule (SPN). The SPN was resected by thoracoscopic wedge resection and was revealed to have characteristics of chordoid meningioma. After confirming the absence of a meningioma in the CNS by brain imaging, the nodule was diagnosed as a primary pulmonary chordoid meningioma...

Aortocaval fistula (ACF) occurs in <1% of all abdominal aortic aneurysms (AAAs), and in 3% to 7% of all ruptured AAAs. The triad of clinical findings of AAA with ACF are abdominal pain, abdominal machinery bruit, and a pulsating abdominal mass. Other findings include pelvic venous hypertension (hematuria, oliguria, scrotal edema), lower-limb edema with or without arterial insufficiency or venous thrombus, shock, congestive heart failure, and cardiac arrest. Surgery is the main treatment modality. We report successful surgical treatment in a patient with a ruptured AAA with ACF who presented with cardiogenic shock...

Hyojung Park, Jinyoung Song, June Huh, I-Seok Kang, Tae-Gook Jun, Ji-Hyuk Yang
This case report concerns a young patient with an extremely rare combination of d-transposition of the great arteries (d-TGA) and anomalous origin of the right subclavian artery. In our patient, the right subclavian artery originated from the pulmonary artery, which is why he did not show reversed differential cyanosis. We conclude that the presence of an aortic arch anomaly should be considered in patients with d-TGA who do not present with reversed differential cyanosis. A further imaging work-up, including computed tomography or magnetic resonance imaging, might be helpful...

A 61-year-old woman who presented with claudication and dyspnea on exertion was found to have severe calcified narrowing of the descending aorta and severe insufficiency of the aortic valve. These findings were compatible with Takayasu arteritis. To treat these hemodynamic abnormalities, extra-aortic bypass surgery combined with replacement of the aortic valve and ascending aorta-to-hemiarch replacement was performed through a separated upper hemi-sternotomy and limited median laparotomy. We present our successful surgical experience with this case...

Neo-aortic insufficiency associated with root enlargement following an arterial switch operation is a serious late complication. To achieve successful surgical correction of this condition, multiple factors should be considered, including the individual patient's anatomy, the challenging nature of the redo procedure, and the patient's young age. However, limited publications have described the use of valve-sparing techniques for the treatment of neo-aortic insufficiency associated with root enlargement following an arterial switch operation...

Background: The nonsurgical treatment of chest wall deformity by a vacuum bell or external brace is gradual, with correction taking place over months. Monitoring the progress of nonsurgical treatment of chest wall deformity has relied on the ancient methods of measuring the depth of the excavatum and the protrusion of the carinatum. Patients, who are often adolescent, may become discouraged and abandon treatment. Methods: Optical scanning was utilized before and after the intervention to assess the effectiveness of treatment...

Background: It is unclear whether mitral valve (MV) repair for degenerative mitral regurgitation (MR) provides the same advantages in the elderly that it does in the general population. Methods: From 1994 to 2016, 188 elderly patients (mean age, 68.3±5.50 years) underwent MV repair (n=153) or MV replacement (n=35) for primary degenerative MR. Early and long-term outcomes were compared before and after propensity score matching (PSM). Results: Before PSM, there was a significant difference in operative mortality (p=0...

One of the complications of permanent pacemaker implantation is unintended phrenic nerve stimulation. A 15-year-old boy with a permanent pacemaker presented with chest discomfort due to synchronous chest wall contraction with pacing beats. Even after reprogramming of the pacemaker, diaphragmatic stimulation persisted. Therefore, we performed thoracoscopic phrenic nerve insulation using a Gore-Tex patch to insulate the phrenic nerve from the wire. A minimally invasive approach using a thoracoscope is a feasible option for retractable phrenic nerve stimulation after pacemaker implantation...

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.

We report a case of successful repair of truncus arteriosus (TA) associated with complete atrioventricular septal defect (c-AVSD) using a staged approach. TA associated with c-AVSD is a very rare congenital cardiac anomaly. No report of successful staged repair in South Korea has yet been published. We performed bilateral pulmonary artery banding when the patient was 33 days old, and total correction using an extracardiac conduit was performed at the age of 18 months. The patient recovered uneventfully and is doing well...
