Confusion of a patent ductus arteriosus (PDA) for the descending thoracic aorta is a fatal error occurring occasionally in infants or neonates. As a result, the left pulmonary artery (LPA) may be misconceived as the PDA, and ligated. This surgical mishap of other hospital leads to serious congestive heart failure and loss of left lung function due to the underdevelopment in the peripheral vascular and alveolar structures in neonates and premature infants. In this report, 3 cases of LPA ligation and subsequent treatment are presented.

Congenitally corrected transposition of the great arteries is a congenital cardiac anomaly with ventriculoarterial discordant connection and atrioventricular discordant connection. This report describes a 17 year old male patient who had congenitally corrected transposition of the great arteries associated with ventricular septal defect and patent ductus arteriosus, underwent patch closure of the ventricular septal defect and suture closure of patent ductus arteriosus, and was discharged on 9th day after surgery with good condition.

Over a 3 year period, 10 premature infants with less than 37 weeks of gestational age underwent ductal ligation for patent ductus arteriosus. No patient died during operations which were done at a mean age of 30 days. One late death at 2 months after operation was not directly attributed to operative procedure. Follow-ups were done in 9 survived patients from 2 to 26 months. Results suggest that surgical ligation is a feasible and effective method for treating symptomatic premature infants with patent ductus arteriosus.

This study evaluated several known echocardiographic markers related to the assessment of severity in dogs with patent ductus arteriosus (PDA) after the closure of ductus arteriosus (DA). Forty-two dogs with patent ductus arteriosus were enrolled in this study. Evaluated echocardiographic markers were left atrial to aortic root ratio, left ventricular end-diastolic dimension to aortic root ratio, indexed left ventricular end-diastolic and end-systolic dimensions, end-diastolic and end systolic volume index, pulmonic flow to systemic flow (Qp/Qs) ratio, velocities of pulmonary regurgitant and systolic jets, pulmonary flow profiles and the presence of mitral regurgitation. Those markers were evaluated before, 1 day, and 30 days after the closure of DA. Statistically significant changes in some echocardiographic markers (i.e., Qp/Qs) were observed. Although several studies in human and dogs have evaluated the clinical outcome of PDA occlusion using several echocardiographic markers, this study has firstly evaluated all echocardiographic markers known to be useful for assessing the clinical outcome of PDA occlusion in human, and has demonstrated that those markers including the Qp/Qs and pulmonary flow profiles were useful in evaluating of clinical outcome of PDA in dogs and the reduction of LA and LV preload after ductal closure could dramatically reduce after successful ductal occlusion of PDA in dogs.

Since the first report of successful ligation of patent ductus arteriosus in 1939, it`s surgical intervention has become a routine and relatively safe procedure. During the past ten years from Aug. 1975 to Aug. 1985, 107 cases were operated on for a patent ductus arteriosus at the Department of thoracic and Cardiovascular Surgery, School of Medicine, Kyungpook National University. Clinical analysis of these cases was performed. Mean age at operation was 9.4 years, ranging from 20 months to 32 years. Sex ratio of female to male was 1.8;1. Most common symptoms were frequent respiratory infection, exertional dyspnea, and palpitation. Diagnosis was made by auscultation, 2 dimensional echocardiography, cardiac catheterization, and cineangiocardiography. A moderate to severe pulmonary hypertension was found in 42 cases [49.4%] in cardiac catheterization. Operative methods were multiple ligation of paten`. ductus arteriosus with or without Dacron or Teflon wrapping in 72 cases [68%], and division and suture in 34 cases [32%]. There were three operative deaths [2.8%]. The causes of death were hemorrhage from tearing of aorta, low cardiac output, and arrhythmia. All of these cases had moderate degree of pulmonary hypertension.

Surgical correction of patent ductus arteriosus is,under most circumstances,highly successful and carries a low mortality. But infected PDA is yet potentially dangerous due to its frequent recurrence and resistant organisms to antibiotics. And,in surgical correction,surgeon may face the possibility of tearing of ductus arteriosus arterial end due to friability and adhesion of its surrounding tissue.This report demonstrats another problem in treatment of infected patent ductus arteriosus.This thirteen years old female patient received susceptible combined antibiotics intravenously from the day of admission and remitted from 4th.week of therapy.This remission state continued for 12days without relapse.But the pulmonary artery ruptured in this remission period.In autopsy,bacteria was not found in ductal vegetation.Also,there was no pulmonary artery aneurysm,Our experience show that in infected PDA,pulmonary artery can rupture spontaneously during remission period without aneurysmal formation.

The first successful percutaneous transcatheter occlusion technique for patent ductus arteriosus achived by Rashkind in 1977.Transcatheter occlusion with the Rashikind double umbrella device is now widely accepted as treatment for patent ductus arterisus. The reported complications include embolization of the device, psudocoarctation left pulmonary artery stenosis, residual shunts, and mechanical hemolysis. We report two cases of severe hemolysis after occlusion of PDA with Rashkind occluder.

A 6-year-old female Maltese dog (body weight 2.0 kg) was referred to the Veterinary Teaching Hospital, Kangwon National University with primary complaints including exercise intolerance and heart murmur. Based on clinical and diagnostic findings including grade V/VI left basal continuous murmur, bounding femoral pulsation, left ventricular enlargement pattern in electrocardiogram, cardiomegaly with aortic bulging on the thoracic radiography, and shunt flow between aorta and pulmonary artery on the echocardiography, the dog was diagnosed as the left-to-right patent ductus arteriosus. The patent ductus arteriosus was successfully treated by lodging a single embolization coil with transjugular approach.

Recently, we met a 12 year old female patient who suffered from bacterial endocarditis and pericarditis which were complicated by patent ductus arteriosus. She was admitted to our hospital because of dyspnea, fever, headache, and generalized ache for 10 days. The initial diagnosis was bacterial endocarditis and pericarditis complicated by patent ductus arteriosus and congestive heart failure. At first, we tried to treat the patient medically with digitalis, diuretics, and massive antibiotics. On echocardiography large amount of pericardial fluid was accumulated mainly right anterior aspect and also noted a large vegetation at pulmonary valve area. With vigorous medical treatment including repeated pericardiocentesis, the patient showed no improvement. So we decided to perform pericardiectomy for elimination of the most probable septic focus. On operation, we encountered an unpredicted event, the pericardium was thickened, distended, and its surface showed pulsating which meant connecting to systemic circulation. We decided to close the operative wound and reoperate her under cardiopulmonary bypass later. On the next day, we operated her under cardiopulmonary bypass later. On the next day we operated her under cardiopulmonary bypass. The operative findings were ruptured main pulmonary artery about 1.5cm in diameter on its ventral portion, the blood from the ruptured main pulmonary artery was filled up the localized pericardial sac due to previous pericarditis. Through the ruptured main pulmonary artery, we also found 0.5cm diametered patent ductus arteriosus. With the aid of partial cardiopulmonary bypass and inserting 24F ballooned Foley catheter at aorta, pericardiectomy was performed first. After completion of the pericardiectomy, total cardiopulmonary bypass was established. With minimum pump flow [0.3L/min/m2] the PDA was closed with two Teflon-felted 4-0 Prolene interrupted sutures. The ruptured main pulmonary artery was also closed using thickened pericardium with three Teflon-felted 4-0 Prolene interrupted sutures. The operation was successful and postoperative course was uneventful. She was discharged on the 16th POD. We report this case as a very rare secondary complication of bacterial endocarditis complicated by patent ductus arteriosus.

Aneurysmal dilatation of the ductus arteriosis has been considered a rare but potentially fatal abnormality. The mechanism of ductal aneurysmal formation remains uncertain. Plain chest radiography has proven helpful in the diagnosis of ductus arteriosus aneurysm (DAA), before the application of transthoracic echocardiography. The transthoracic echocardiography is an important tool for the diagnosis and follow-up of DAA. We present a case of congenital ductus arteriosus aneurysm in a newborn, that was an incidental discovery. The diagnosis was made by echocardiography, three-dimensional surface rendering computed tomography (CT), and spontaneous regression after four weeks of follow-up.
