1/67. Successful treatment of tracheomalacia associated with esophageal atresia without a tracheoesophageal fistula by aortopexy: report of a case.tracheomalacia (TM) is well known as a complication associated with esophageal atresia (EA) and tracheoesophageal fistula (TEF); however, the occurrence of TM requiring surgical treatment in a patient having EA without a tracheoesophageal fistula has never been reported. We describe herein a rare case of TM associated with EA without TEF. Respiratory distress was caused by compression of the trachea by a severely dilated upper esophageal pouch with weakness of the tracheal wall. Aortopexy was performed, and an excellent postoperative result was achieved.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
2/67. Respiratory distress due to tracheal compression by the dilated innominate artery.The case reported is of an 88 yr old female with hypertension and respiratory distress. A chest radiograph revealed a widening of the upper mediastinum. Computed tomographic scanning revealed tracheal compression by the innominate artery, which was elongated and curved. After intubation, she was treated with antihypertensive drugs. This resulted in the remarkable recovery of the patient from respiratory distress. To the authors' knowledge, this is the first reported case of respiratory distress owing to tracheal compression by elongation and curvature of the innominate artery.- - - - - - - - - - ranking = 6keywords = compression (Clic here for more details about this article) |
3/67. Aqueduct stenosis due to venous ectasia with a dural arteriovenous fistula.We report aqueduct compression by venous ectasia in a 65-year-old man with a dural arteriovenous fistula in the posterior cranial fossa draining into a superior vermian vein. Conventional and phase-contrast MRI showed the aqueduct stenosis and the causative dilated vein.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
4/67. A novel technique for giant left atrium reduction.We herein describe a safe and reproducible technique for left atrial volume reduction in patients with a giant left atrium. In a 56-year-old patient undergoing redo mitral valve replacement, the left atrium measured 18 x 20 x 17 cm occupying the middle-lower segment of the right hemithorax with compression of the adjacent organs. The left atrial volume was reduced by triangular resections of the atrial wall and the mitral valve was replaced using a mechanical prosthesis. The postoperative course was uneventful and the left atrial diameter was 11.2 cm at the latest control.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
5/67. Successful intrauterine shunting of a sacrococcygeal teratoma (SCT) causing fetal bladder obstruction.We report a case of a sacrococcygeal teratoma (SCT) diagnosed at 22 weeks with a substantial intrapelvic cystic extension leading to bladder outlet obstruction and hydronephrosis at 27 weeks. Prenatal percutaneous shunting of the cystic teratoma was performed at 28 weeks to avoid prolonged fetal pelvic compression by the tumour that could have adverse effects by stretching the pelvic plexus and sacral nerves. Urinary dilatation resolved completely after shunting and a 3880 g baby girl was delivered at 39 weeks. The potential benefits of in utero shunting to avoid urological complications of SCTs with intrapelvic extension are discussed.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
6/67. Total occlusion of left main coronary artery by dilated main pulmonary artery in a patient with severe pulmonary hypertension.A 34-year-old woman was admitted to the hospital because of recently aggravated right heart failure without angina for 5 months. When she was 25 years old, patch repair with polytetrafluoroethylene (PTFE) was performed for the secondum type of atrial septal defect (ASD) with moderate pulmonary hypertension. The chest PA, echocardiography and cardiac catheterization at current admission revealed Eisenmenger syndrome without intracardiac shunt. Chest CT scan with contrast revealed markedly dilated pulmonary trunk, both pulmonary arteries and concave disfigurement of the left side of the ascending aorta suggesting extrinsic compression, as well as total occlusion of the ostium of the left main coronary artery that was retrogradly filled with collateral circulation from the right coronary artery. The coronary angiography showed normal right coronary artery and the collaterals that come out from the conus branch to the mid-left anterior descending artery (LAD) and that from distal right coronary artery to the left circumflex artery (LCX) and to the distal LAD, respectively. On aortography, the left main coronary artery was not visualized with no stump, suggestive of total occlusion of the ostium of the left main coronary artery. From our experience, it is possible to say that the occlusion of the ostium of the left main coronary can be induced by the dilated pulmonary artery trunk due to ASD with pulmonary hypertension and that, if the ASD closure was too late, the narrowing or obstruction of the left coronary artery could not be resolved even after operation owing to irreversible pulmonary hypertension.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
7/67. dilatation of the intrahepatic bile ducts associated with benign liver lesions: an unusual finding.In three patients presenting different types of liver lesions, including isolated cyst, focal nodular hyperplasia (FNH), and hemangioma, intrahepatic bile duct dilatation was observed on US and CT. Final diagnosis was obtained by surgery in two cases (cyst and FNH) and by 1-year follow-up in one patient presenting an isolated hemangioma. The only common characteristic in our three cases was that lesions were present in segment four according to Couinaud's classification, at the level of the transverse fissure, suggesting that a space-occupying lesion at this site may cause compression of the common hepatic duct and right or left intrahepatic bile ducts. Our report indicates that compression may occur even with lesion of moderate size (35-40 mm in diameter). A benign liver lesion may cause a bile duct dilatation, particularly if located in segment 4, close to the hilum. awareness of this possibility is important to avoid unnecessary invasive diagnostic procedures, particularly when all imaging criteria are consistent with a benign lesion.- - - - - - - - - - ranking = 2keywords = compression (Clic here for more details about this article) |
8/67. Is unexplained third trimester intrauterine death of fetuses with gastroschisis caused by umbilical cord compression due to acute extra-abdominal bowel dilatation?We report on a case of gastroschisis in which sudden dilatation of extra-abdominal bowel at 34 1 weeks was followed by an unusual umbilical flow velocity waveform (diastolic notching). The condition was associated with normal umbilical Doppler indices, brain sparing effect and a non-reactive cardiotocograph (CTG). Findings at postnatal surgery strongly suggested severe cord compression by the herniated dilated bowel. The significance of notching in the umbilical artery waveform is discussed, as is the potential importance of this sign in the prepartum management of fetuses with gastroschisis.- - - - - - - - - - ranking = 5keywords = compression (Clic here for more details about this article) |
9/67. Hepatic involvement in hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber disease).Hepatic involvement in hereditary hemorrhagic telangiectasia is infrequent and poorly studied. We describe a 62-year-old woman with Rendu-Osler-Weber (ROW) disease and recurrent gastrointestinal bleeding episodes. blood chemistry was consistent with the presence of cholestasis. Imaging studies revealed prominent vascular abnormalities in the liver and focal intrahepatic bile duct dilatations. The intimate anatomic relationship of the vascular abnormalities to the dilated bile ducts suggests that external vascular compression could have caused their dilatation. To our knowledge, this mechanism has not been proposed in the literature as a possible explanation of biliary dilatation in patients with ROW.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
10/67. Obstructive pneumonia: an indication for surgery in mega aorta syndrome.A 76-year-old woman with annuloaortic ectasia, aortic regurgitation, and aneurysmal dilatation extending from the root to mid descending aorta presented with symptoms of bronchial compression and obstructive pneumonitis. Despite vigorous antibiotic treatment and physiotherapy, the pneumonitis persisted with clinical and radiologic deterioration. An emergency operation was performed to relieve bronchial compression. The operation comprised homograft aortic root replacement with prosthetic replacement of the arch and descending aorta. Postoperatively the pneumonia rapidly resolved.- - - - - - - - - - ranking = 2keywords = compression (Clic here for more details about this article) |
