1/266. Endovascular stent graft repair of aortopulmonary fistula.Two patients who had aortopulmonary fistula of postoperative origin with hemoptysis underwent successful repair by means of an endovascular stent graft procedure. One patient had undergone repeated thoracotomies two times, and the other one time to repair anastomotic aneurysms of the descending aorta after surgery for Takayasu's arteritis. A self-expanding stainless steel stent covered with a Dacron graft was inserted into the lesion through the external iliac or femoral artery. The patients recovered well, with no signs of infection or recurrent hemoptysis 8 months after the procedure. Endovascular stent grafting may be a therapeutic option for treating patients with aortopulmonary fistula.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
2/266. Post-traumatic thoracic pseudoaneurysm repair with an endoluminal expandable stent.Recent technological improvement has allowed endoluminal correction of thoracic and abdominal aortic aneurysm through percutaneous insertion of expandable stents. A woman who presented with chronic pseudoaneurysm of the thoracic aorta 10 years after being in a car accident is presented. A Talent stent was introduced through the femoral artery and successfully deployed under fluoroscopic guidance across the aneurysmal defect. Recovery was uneventful, and 12 months later the patient remained asymptomatic.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
3/266. Asymptomatic dissection of the ascending aorta: diagnosis by transesophageal echocardiography.A young man with marfanoid habitus underwent transesophageal echocardiography to evaluate an aortic root abnormality visualized on transthoracic echocardiography. Transesophageal echo demonstrated a type A aortic dissection traversing across the right sinus of valsalva but not involving the aortic valve, right coronary artery, or pericardial sac. The aorta was not dilated. This is apparently the first reported case of an asymptomatic and uncomplicated aortic dissection localized to the sinus of valsalva.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
4/266. Antegrade filling of an occluded right coronary artery via collaterals from a separate conus artery, a previously undescribed collateral pathway.The conus artery is known to be a frequent supplier of collaterals to the LAD and distal marginal branches of the RCA. In this report we describe a patient with an ostial RCA occlusion who was found to have, during selective conus artery injection, excellent collaterals directly to the proximal RCA. This anatomy was initially mistaken for diffuse disease of the ostium and proximal portion of the RCA.- - - - - - - - - - ranking = 10keywords = artery (Clic here for more details about this article) |
5/266. Surgery of the dissecting aneurysm involving a right aortic arch.A dissecting aneurysm in association with a right aortic arch is extremely rare. However, a 50-year-old male was diagnosed as having a dissecting aneurysm (DeBakey IIIa) with a right aortic arch, right descending aorta and an aberrant retro-esophageal left subclavian artery. A graft replacement of the right descending aorta was successfully performed under right thoracotomy and partial cardiopulmonary bypass. Precise anatomical definition and proper surgical procedure permitted a successful surgical result.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
6/266. Simultaneous selective cerebral perfusion and systemic circulatory arrest through the right axillary artery for aortic surgery.The duration of safe circulatory arrest for replacement of the ascending aorta for a type A dissection, without additional cerebral perfusion measures, is not clearly defined. If prolonged periods (> 60 minutes) are anticipated, retrograde cerebral perfusion or selective antegrade carotid perfusion may be required. The latter requires separate cannulas with subsequent snaring of the cerebral vessels, which may be time consuming and cumbersome. We propose an alternative method whereby the right axillary artery is cannulated for cardiopulmonary bypass and, when the desired hypothermic temperature is achieved, the flows are turned down to 500 mL/min. The origin of the innominate artery is then occluded establishing selective antegrade right carotid artery perfusion. The distal ascending or aortic arch anastomosis is then performed while the remainder of the body is under selective systemic circulatory arrest. The proximal aortic anastomosis is performed after the graft is clamped proximally and flows return to appropriate perfusion levels.- - - - - - - - - - ranking = 9.3991043118666keywords = artery, carotid artery, carotid (Clic here for more details about this article) |
7/266. Aortic dissection of Kommerell's diverticulum in Marfan's syndrome.We report a surgical case of chronic aortic dissection with an entrance tear on Kommerell's diverticulum, a rare embryologic anomaly, with an extension to the arteria lusoria, in a patient with Marfan's syndrome. The operation consisted of aortic root and arch replacement with reimplantation of the right subclavian artery in the right carotid artery under circulatory arrest and deep hypothermia.- - - - - - - - - - ranking = 3.6207072404479keywords = artery, carotid artery, carotid (Clic here for more details about this article) |
8/266. Two-stage operation for multiple aneurysms of the thoracic aorta, abdominal aorta, and left common iliac artery in an octogenarian.Multiple aortic aneurysms are well described in the surgical literature. However, there are many problems related to surgical treatment of elderly patients with such aneurysms. This report presents the case, an octogenarian with multiple aortic aneurysms that were successfully treated by graft replacement. An 82-year-old man with a descending aortic aneurysm was referred to our institution for surgery. In addition to the previously diagnosed aneurysm, computed tomography and aortography showed an abdominal aortic aneurysm and a left common iliac aneurysm. Since the patient was an elderly man with chronic obstructive pulmonary disease, a two-stage operation was performed. The abdominal aortic aneurysm and left common iliac aneurysm were resected first due to the risk of thromboembolism from the abdominal aortic aneurysm during surgery involving replacement of the descending aorta under femoro-femoral (F-F) bypass. Fifty-two days after the first operation, a second operation was performed to repair the descending aortic aneurysm. The postoperative course was uneventful. angiography after the operation showed satisfactory replacement of the multiple aortic aneurysms. The patient was discharged 25 days after the second operation.- - - - - - - - - - ranking = 4keywords = artery (Clic here for more details about this article) |
9/266. Combined coronary artery bypass grafting and repair of aneurysm of the descending aorta.The outcome of patients with thoracic or thoracoabdominal aortic aneurysm is often determined by the concomitant coronary artery disease. Two patients with thoracic and thoracoabdominal aortic aneurysm and concomitant single-vessel coronary artery disease underwent combined myocardial revascularization and repair of aortic aneurysm. The operations were performed through a left thoracotomy and thoracoabdominal incision with distal aortic perfusion using a partial femoro-femoral bypass and selective right lung ventilation. Coronary anastomoses were performed on the beating heart, and the aneurysm was replaced with a woven Dacron tube graft.- - - - - - - - - - ranking = 7.2211985217061keywords = artery, artery disease (Clic here for more details about this article) |
10/266. Coronary artery aneurysms, aortic dissection, and hypertension secondary to primary aldosteronism: a rare triad. A case report.Primary aldosteronism is a relatively uncommon etiology of hypertension. plasma renin activity is suppressed in the majority of the cases but not always. plasma renin activity has been associated with increased vascular injury. The occurrence of vascular complications has rarely been reported with low plasma renin activity. The authors report a case of long-standing secondary hypertension due to primary aldosteronism with coronary artery aneurysms and aortic dissection. Diagnosing is important, for therapeutic intervention can be curative.- - - - - - - - - - ranking = 5keywords = artery (Clic here for more details about this article) |
