1/110. Mitral valve replacement through dilated aortic annulus in Marfan's syndrome.A 30-year-old man presented with severe aortic regurgitation due to an ascending aortic aneurysm and mitral valve insufficiency in conjunction with active endocarditis. He underwent combined aortic root replacement by a composite graft and mechanical mitral valve replacement. After excision of the aortic valve cusps the mitral valve was approached through the extremely dilated aortic annulus. This technique is seldom used. Mitral valve replacement through the aortic root can be advantageous in selected patients to minimize trauma and reduce myocardial ischemic time.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/110. A single-stage operation for bicuspid aortic valve, annulo-aortic ectasia, hypoplastic aortic arch, and coarctation of the aorta: A case report.The patient was an 18-year-old man who had been diagnosed as having a bicuspid aortic valve and dilatation of the ascending aorta six years previously. As he grew up, aneurysmal change of the ascending aorta and hypertension in the upper body gradually progressed. Preoperative evaluation showed annulo-aortic ectasia and the following congenital abnormalities: bicuspid aortic valve, hypoplastic aortic arch, and coarctation of the aorta. Composite graft replacement and extended total aortic arch replacement were carried out.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
3/110. Idiopathic saccular aneurysm of the azygos vein.Idiopathic saccular aneurysm of the azygos vein is a rare condition. We report the case of a 52-year-old man with saccular aneurysm of the azygos vein who underwent surgical resection. Preoperative dynamic computed tomography revealed strong and rapid enhancement of the chest mass. magnetic resonance imaging showed a thoracic tumor with low signal intensity on the T1-weighted image and coexistence of low and high signal intensity on the T2-weighted image. Intraoperative findings showed cystic dilatation of the azygos vein. Although an accurate preoperative diagnosis of saccular azygos vein aneurysm is difficult, especially differential diagnosis between this anomaly and mediastinal tumors, a markedly enhanced mass shown by dynamic computed tomography was useful for the preoperative diagnosis of this anomaly.- - - - - - - - - - ranking = 7keywords = aneurysm (Clic here for more details about this article) |
4/110. Isolated dissection of the celiac artery--a case report.Isolated arterial dissection, which occurs with the absence of aortic dissection, has been reported in carotid and renal arteries but rarely in visceral arteries. A case of isolated celiac artery dissection is reported here. A healthy 58-year-old man experienced sudden upper abdominal pain, which continued for several days. A body computed tomogram (CT) showed a multiple low-density wedge-shaped area in the spleen, which was diagnosed as splenic infarction, and an aneurysm with thrombus in the celiac artery. A selective angiogram showed dilatation of the celiac artery with wall irregularity, and proximal occlusion of the hepatic artery. The distal hepatic artery was fed by collateral arteries from the superior mesenteric artery. splenic infarction was probably due to the embolism from the thrombus in the dissected celiac artery. The absence of other vascular lesions and causes or risks for the arterial dissection would suggest the occurrence of spontaneous dissection. The dissection of visceral arteries should be considered in diagnosing acute abdominal pain.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
5/110. Multiple arterial ectasias in patients with sarcoidosis and uveitis.PURPOSE: To describe and evaluate the cause of a clinical entity characterized by bilateral intraocular inflammation, multiple arterial ectasias including beading, macroaneurysms, comma-like ectasias and kinking, with vasculitis, staining of the optic disk and multiple peripheral round punched-out hypopigmented chorioretinal scars in elderly patients. The formation and the course of the arterial ectasias is analyzed. methods: Seven patients with this syndrome were evaluated by clinical examination, fluorescein angiography, and systemic investigations. RESULTS: Three of the seven patients had a biopsy characteristic of sarcoidosis, two others showed positive bronchoalveolar lavage, as well as other analyses and tests suggesting sarcoidosis, and two showed other findings suggestive of sarcoidosis. The patients were all over 60 years of age and had arterial hypertension. In two patients, an arterial ectasia developed at the site of previous focal inflammation. The macroaneurysms either remained unchanged, became comma-like ectasias, arterial kinks, or completely vanished. CONCLUSION: Elderly patients with multiple arterial ectasias, uveitis, disk staining, and peripheral chorioretinitis should be thoroughly investigated for sarcoidosis. We suggest that sarcoidosis may cause some degree of arteritis, which may weaken the arterial wall, with resulting ectasia. Arterial hypertension may play a role in the formation of the ectasias by increasing the pressure on the arterial wall weakened by inflammation.- - - - - - - - - - ranking = 2keywords = aneurysm (Clic here for more details about this article) |
6/110. Multiple coronary artery aneurysms combined with abdominal aortic aneurysm.Coronary artery aneurysm (CAA) is defined as coronary dilatation which exceeds the diameter of a normal adjacent segment or the diameter of the patients's largest coronary vessel by as much as 1.5 times. It is an uncommon pathology with a frequency of 1-4% in routine autopsies or coronary angiographies. atherosclerosis plays an important role in the development of CAA, and it may be a predominant cause in the majority of patients. However, the timing of surgical intervention and the treatment options for CAA are still controversial. In this report, we present a patient who had multiple CAAs of all main coronary arteries and abdominal aortic aneurysm. Different treatment modalities and indications are also discussed.- - - - - - - - - - ranking = 10keywords = aneurysm (Clic here for more details about this article) |
7/110. Dilated coronary sinus mimicking posterior left ventricular aneurysm.Dilation of the coronary sinus is mostly a congenital lesion. As acquired lesion it was found to be associated with poor left ventricular function. In the present case an angiographic diagnosed posterior left ventricular aneurysm was during surgery found to be a dilated coronary sinus. Preoperative left ventricular function was normal.- - - - - - - - - - ranking = 5keywords = aneurysm (Clic here for more details about this article) |
8/110. Rapid normalization of marked dilatation of the cerebral duro-venous system in a newborn infant mimicking a great vein of Galen varix.A newborn infant with a marked dilatation of the cerebral duro-venous system is presented. The patient was diagnosed as having a vein of Galen aneurysmal varix by a cranial ultrasound examination immediately following delivery. Computed tomographic angiography on the following day, however, showed a marked dilatation of the cerebral duro-venous system, including the great vein of Galen, superior sagittal sinus, torcular herophili and transverse sinuses. There were no arteriovenous fistulas at the vein of Galen. dilatation of the duro-venous system and concomitant heart failure subsided rapidly after intravenous administration of indomethacin for the treatment of the patent ductus arteriosus on the fourth day of life. dilatation of the duro-venous system in a newborn infant should be differentiated from any form of vein of Galen aneurysm.- - - - - - - - - - ranking = 2keywords = aneurysm (Clic here for more details about this article) |
9/110. Familial multiple trichoepithelioma associated with subclavian-pulmonary collateral vessels and cerebral aneurysm--case report.A 63-year-old woman presented with cerebellar infarction caused by occlusion of the right posterior inferior cerebellar artery. She had papules on her face that were identified histologically as multiple trichoepithelioma. Angiography revealed right subclavian-pulmonary collateral vessels and a cerebral aneurysm arising from the bifurcation of the right middle cerebral artery. Her grandmother, mother, and uncle had had similar papules, and the deaths of her mother and uncle were due to subarachnoid hemorrhage.- - - - - - - - - - ranking = 5keywords = aneurysm (Clic here for more details about this article) |
10/110. Saccular aneurysm of pulmonary autograft after the Ross procedure.The Ross procedure, which includes removal of the malformed aortic valve and replacement of a pulmonary autograft in the aortic position, has increased the number of available treatment options. Recently, dilatation of the autograft pulmonary root after the Ross procedure has been reported as a complication. We report a patient with bicuspid aortic valve malformations and aortic annulus dilatation, who had a saccular-form, true-type, aneurysm in the pulmonary autograft seven months after the Ross procedure. These changes have not been described so far as complication. Pathologically, marked mucoid degeneration was noted in the tunica media of the aneurysm, as well as in the original aortic root. These findings may suggest similar pathological characteristics between the aorta and pulmonary arteries. Hence, the surgical risks accompanying vascular characteristics in patients with congenital aortic valve malformations should be considered.- - - - - - - - - - ranking = 6keywords = aneurysm (Clic here for more details about this article) |
