1/99. Ruptured distal aortic arch aneurysm associated with arteriosclerosis obliterans.A 73-year-old man with a ruptured distal aortic arch aneurysm into the pericardial space, mediastinum and right pleural space is described. The patient underwent a successful total aortic arch replacement using deep hypothermia, systemic circulatory arrest and selective cerebral perfusion. extracorporeal circulation was established with right axillar arterial perfusion due to arteriosclerosis obliterans (ASO). Presentation and management are discussed.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
2/99. cardiac tamponade and death from intrapericardial rupture [corrected] of sinus of valsalva aneurysm.A 35-year-old woman presented with dyspnea and chest pain. She had a large aneurysm of the non-coronary sinus of valsalva. Before her scheduled urgent surgery, the patient collapsed and died of cardiac tamponade secondary to intrapericardial rupture of the aneurysm. We would advocate urgent repair of this type of lesion to prevent such an outcome. We are aware of no other specific reports addressing extracardiac rupture of non-coronary cusp aneurysms [corrected].- - - - - - - - - - ranking = 11.219793619976keywords = coronary (Clic here for more details about this article) |
3/99. diagnosis of ruptured sinus of valsalva aneurysms: potential value of transesophageal echocardiography.Two patient cases are reported in which an aneurysm of the right coronary sinus of valsalva ruptured into the right ventricular outflow tract, near the crux of the heart. Transthoracic two-dimensional echocardiography and transesophageal echocardiography using Doppler color flow mapping allowed accurate preoperative assessment of the left-to-right shunt, which was subsequently confirmed by contrast aortography and surgery.- - - - - - - - - - ranking = 5.6098968099882keywords = coronary (Clic here for more details about this article) |
4/99. Endovascular stent-grafting via the aortic arch for distal arch aneurysm: An alternative of endovascular stent-grafting in a complicated case.A 67-year-old man with severe discomfort was diagnosed with a rupture of the thoraco-abdominal aneurysm, a distal arch aneurysm and triple coronary artery disease. After emergency surgery for a thoracoabdominal aneurysm, a scheduled surgery for coronary artery bypass grafting and endoluminal stent-grafting for the distal arch aneurysm was performed simultaneously. A stent-graft was introduced into the descending aorta via a small incision on the arch aorta. Open endovascular stent-grafting via the arch aorta is an alternative for repairing a distal arch aneurysm with coronary artery bypass grafting.- - - - - - - - - - ranking = 16.829690429965keywords = coronary (Clic here for more details about this article) |
5/99. Stent-grafting to descending thoracic aorta during coronary artery bypass grafting.We report on 2 patients who underwent successful concomitant operation of coronary artery bypass grafting and stent grafting to descending thoracic aortic aneurysms. The device was inserted through a small linear incision on the anterior wall of the aortic arch. Intraoperative stent grafting to descending thoracic aortic aneurysms is an alternative therapeutic option for patients who require concomitant coronary artery bypass grafting and descending aortic replacement.- - - - - - - - - - ranking = 33.659380859929keywords = coronary (Clic here for more details about this article) |
6/99. Successful completion of endoluminal repair of an abdominal aortic aneurysm after intraoperative iatrogenic rupture of the aneurysm.PURPOSE: A method of achieving successful completion of endoluminal repair of an abdominal aortic aneurysm (AAA) in the presence of intraoperative iatrogenic rupture of the aneurysm is reported. methods: An 83-year-old woman with an AAA that was 7 cm in diameter was treated electively by means of endoluminal repair with a Vanguard bifurcated prosthesis (boston Scientific, Natick, Mass). No difficulty was experienced with the introduction of the delivery catheter, despite extreme angulation in the aneurysm. An acute episode of hypotension prompted an aortogram to be performed. Extravasation of contrast outside the aneurysm sac was demonstrated. The balloon on the delivery catheter was immediately advanced to the suprarenal aorta and inflated. hypotension was reversed, and hemodynamic stability was restored, thus enabling deployment of the prosthesis to proceed and the repair to be completed by means of the endoluminal method. RESULTS: The patient's blood pressure remained stable after deflation of the balloon, allowing a postprocedure aortogram to be performed. Exclusion of the aneurysm sac was demonstrated. Exclusion of the aneurysm sac from the circulation and a large retroperitoneal hematoma were confirmed by means of a postoperative contrast computed tomography scan. convalescence was complicated by acute renal failure, pneumonia, and prolonged ileus. The patient remained well and active at the follow-up examination 6 months after operation. CONCLUSION: Iatrogenic perforation of an AAA during endoluminal repair may be treated by endovascular means and does not necessarily require conversion to open repair, although this may be the safest option.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
7/99. Ruptured aneurysm of the sinus of valsalva in association with persistent left superior vena cava--a case report.A 58-year-old man presenting with chest pain and dyspnea was diagnosed by transesophageal echocardiography and cardiac catheterization to have the rare combination of ruptured aneurysm of noncoronary sinus of valsalva into the right ventricle in association with persistent left superior vena cava. These defects were confirmed at cardiac surgery. This case shows the importance of complementary use of invasive and noninvasive methods together in the diagnosis of rare combinations of lesions.- - - - - - - - - - ranking = 5.6098968099882keywords = coronary (Clic here for more details about this article) |
8/99. Echocardiographic diagnosis of sinus Valsalva aneurysm rupture in two pediatric patients.Sinus Valsalva aneurysm rupture (SVAR) is a rare cardiac abnormality that requires surgical correction when diagnosed. Previously, cardiac catheterization and angiography were thought to be necessary for its diagnosis. We present two pediatric cases of SVAR with subarterial ventricular septal defect (VSD) diagnosed noninvasively by echocardiography; surgical findings confirmed the diagnosis. In both of our cases the origin of SVAR was the right coronary sinus. The first case was ruptured into the right ventricular cavity; the second was ruptured into the right ventricular outflow tract. Continuous murmurs heard during follow-up of children with VSD must alert the physician to this pathology. Combined two-dimensional, Doppler and color-Doppler echocardiography is an accurate, noninvasive method for diagnosis of SVAR.- - - - - - - - - - ranking = 5.6098968099882keywords = coronary (Clic here for more details about this article) |
9/99. dissection and rupture of the ascending aorta. Unusual complications of aortocoronary bypass surgery.This is a report concerning two cases of unusual complications, dissection and rupture of the ascending aorta, secondary to saphenous vein bypass surgery. We recommend that evaluation of patients undergoing saphenous vein bypass surgery include careful image-intensifier fluoroscopic examination during coronary arteriography. If aneurysmal dilatation of the aorta or calcification is observed, ascending aortography should be performed to better evaluate the aorta, and surgeons should be alerted to use appropriate maneuvers and techniques to minimize the risk of complications in the aortic site of the vein anastomosis. Internal mammary coronary-artery bypass should be the procedure of choice in such conditions.- - - - - - - - - - ranking = 33.659380859929keywords = coronary (Clic here for more details about this article) |
10/99. Aorto-right artrial fistula: a rare complication of aortic dissection.We describe the successful surgical repair of an acute aortic dissection that had caused an aorto-right atrial fistula in a 67-year-old man. The patient was admitted to the hospital on an emergency basis because of severe heart failure. The diagnosis of acute aortic dissection with rupture into the right atrium was confirmed by use of intraoperative transesophageal echocardiography, although rupture of a sinus of valsalva aneurysm into the right atrium had been suggested initially by 2-dimensional and Doppler transthoracic echocardiography. At surgery, we found the patient to have aortic arch dissection with complete separation of the right coronary artery from the sinus of valsalva and a false lumen that had ruptured into the right atrium. The aortic arch was repaired directly. The ascending aorta was successfully replaced with a composite graft. Aortic dissection with rupture into the right atrium is extremely rare and leads to death rapidly. As shown in this case, such a condition might be mistaken for an aneurysmal rupture of the sinus of valsalva, with use of transthoracic echocardiography alone. Transesophageal echocardiography is a useful noninvasive method to further define or confirm the diagnosis. Early surgical intervention is necessary in patients with this condition to prevent profound shock and end-organ failure.- - - - - - - - - - ranking = 5.6098968099882keywords = coronary (Clic here for more details about this article) |
