1/40. Left main coronary artery compression by aneurysmal pulmonary artery in a patient with tetralogy of fallot with absent pulmonary valve.We describe an 11-year-old girl with tetralogy of fallot and absent pulmonary valve, who on selective coronary angiography was found to have extrinsic compression of the left main coronary artery by the aneurysmally dilated pulmonary artery. This abnormality has not been reported previously.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/40. Pseudoaneurysm formation after infected modified Blalock-Taussig shunt: echocardiographic findings.The modified Blalock-Taussig (B-T) shunt is well recognized as a palliative procedure for cyanotic congenital heart disease in infants. Pseudoaneurysm formation after a modified B-T shunt is a rare complication. We present the case of a 9-month-old girl with tetralogy of fallot who had undergone a modified left B-T shunt at 5 months of age and developed a pseudoaneurysm after an episode of infective endocarditis as detected by echocardiography. Compression of the left bronchus, displacement of the mediastinum to right chest, and paralysis of the left hemidiaphragm were found. Magnetic resonance images, computed tomography scans, aortograms, and selective angiograms demonstrated the presence of a large pseudoaneurysm. The compression syndrome gradually disappeared after aneurysmectomy.- - - - - - - - - - ranking = 3.0410940419108keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
3/40. Pseudoaneurysm of subclavian artery 21-years after staged repair of tetralogy of Fallot.Three cases of pseudoaneurysm of subclavian artery in long-term follow-up after staged repair of tetralogy of fallot are described. The angiographical study revealed that aneurysms were located in the systemic end area of previously ligated modified Blalock-Taussing shunt. Aneurysmectomy with resection of a shunt and segment of subclavian artery was performed. We believe division of a prosthetic shunt should be routinely performed during complete repair of tetralogy to prevent morbidity in the long-term follow-up period.- - - - - - - - - - ranking = 1.9205470209554keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
4/40. Combined primary repair of tetralogy of fallot and aortic root replacement.tetralogy of fallot associated with ascending aortic aneurysm and aortic valve regurgitation is unusual. This combination necessitates a change in operative strategy during complete tetralogy repair. We present a 43-year-old woman who successfully underwent composite graft replacement of the ascending aorta and aortic valve during primary complete tetralogy repair. Histologic examination of the aorta revealed medial degeneration.- - - - - - - - - - ranking = 0.2keywords = aneurysm (Clic here for more details about this article) |
5/40. tetralogy of fallot with absent pulmonary valve: a case complicated by bilateral relapsing pneumothorax.We report a case of a neonate with tetralogy of fallot with aneurysmal dilatation of the pulmonary artery, complicated by bilateral relapsing pneumothorax. The relapsing air leak made it necessary to place up to five chest drains and to switch from conventional ventilation to high frequency ventilation. In the course of 30 days, all drains were removed. Once other anatomical and functional malformations of the respiratory system had been appropriately excluded and reasonable haemodynamic stability had been achieved, the patient underwent successful radical corrective heart surgery in hypothermia and cardioplegia. We emphasize the advantage of resolving respiratory failure preoperatively to guarantee the success of corrective heart surgery and treatment of other surgically severe cases.- - - - - - - - - - ranking = 0.2keywords = aneurysm (Clic here for more details about this article) |
6/40. Pseudoaneurysm of the right ventricular outflow tract complicating balloon dilatation for tetralogy of fallot.Balloon dilatation is one of the treatment options in symptomatic infants with tetralogy of fallot and hypoplastic pulmonary annulus and pulmonary artery. A balloon dilatation was performed on a 28-day-old infant with tetralogy of fallot with an appropriate balloon. The patient developed two pseudoaneurysms on the right ventricular outflow tract after the procedure which were diagnosed when the patient was admitted for total correction at 20 months of age. This case demonstrates an unusual but potentially life-threatening long-term complication of this procedure.- - - - - - - - - - ranking = 1.7205470209554keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
7/40. Aneurysm of the right ventricular outflow following bovine valved venous conduit insertion.A case of aneurysm of the right ventricular outflow tract is described after repair of tetralogy of fallot using a Contegra supported conduit. Angiograms revealed that the aneurysm was located between the ventricular anastomosis and the proximal ring of the conduit confirming echocardiographic data. Because the conduit between the rings was not dilated, the valve was perfectly functioning. Pulmonary anastomosis was severely stenosed explaining the dilatation seen below. Conduit replacement with resection of the aneurysmal part of the failing conduit was performed. Supported conduits do not eliminate the risk of secondary dilatation below the artificial ring but preserve valvular function.- - - - - - - - - - ranking = 0.6keywords = aneurysm (Clic here for more details about this article) |
8/40. Pseudoaneurysm following modified Blalock-Taussig shunt: a rare complication mimicking pulmonary disease.The authors report a pseudoaneurysm in a 2-year-old boy presenting with fever, increasing cyanosis and right upper lung shadowing on a chest radiograph at six weeks following modified Blalock-Taussig shunt surgery. echocardiography and a CT scan of the chest revealed a large pseudoaneurysm originating from the right subclavian artery at the proximal insertion of modified Blalock-Taussig shunt. The patient underwent aneurysmal resection, Blalock-Taussig shunt removal, right subclavian artery ligation and the creation of a central shunt between the ascending aorta and main pulmonary artery. Unfortunately, the patient died 3 hours after the operation.- - - - - - - - - - ranking = 2.8410940419108keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
9/40. Prosthesis endocarditis: treatment of a case occurring five years after a Rastelli-Ross operation.A severe staphylococcal septicemia originating from an unknown focus occurred in a 17-year-old patient who had undergone a Rastelli-Ross operation 5 years earlier. The clinical course was complicated by extensive bilateral pneumonia, diffuse intravascular coagulation, and glomerulonephritis. After 4 weeks of intensive conservative treatment, including a daily regimen of 16 Gm. of cloxacillin, the patient was operated upon for a rapidly progressive false aneurysm, which had resulted from dehiscence of the anastomosis between the prosthesis and ventricle. The excised prosthesis proved to be sterile. The postoperative course was uneventful. cloxacillin treatment was continued for 6 months, initially parenterally and later orally. After discontinuation of therapy, no signs of infection have occurred. Right-sided intracardiac or intravascular prosthetic material may be particularly susceptible to infections originating from the body surface.- - - - - - - - - - ranking = 0.2keywords = aneurysm (Clic here for more details about this article) |
10/40. Late-onset Blalock-Taussig shunt occlusion due to a subclavian artery pseudoaneurysm.A 3-month-old infant with tetralogy of fallot presented with progressive severe cyanosis and intractable acidosis about 2 months after a successful modified right-sided Blalock-Taussig shunt. At cardiac catheterization, the suspected shunt malfunction was confirmed. It was due to a bulky, pear-like mass arising from the right subclavian artery and compressing the polytetrafluoroethylene conduit. Any attempt to recanalize the shunt by percutaneous techniques proved unsuccessful. At surgery, a huge dilation of the anterior wall of the right subclavian artery, that sharply bent the prosthetic conduit, was found. Pathologic examination revealed that the compressing mass was pseudo-aneurysmal in nature. Despite a second successful shunt operation with a dramatic clinical improvement, the patient died due to multiorgan failure 72 hours following surgery. Extrinsic compression by a false aneurysm is a rare cause of shunt occlusion that should always be suspected in patients presenting with a rapidly progressive shunt malfunction late after a successful shunt procedure.- - - - - - - - - - ranking = 4.0821880838215keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
