ABSTRACT
<p>A 50-year-old man with an extensive thoracic aortic aneurysm underwent staged surgery which consisted of preceding total aortic arch replacement with the frozen elephant trunk technique using J Graft Open Stent Graft<sup>®</sup>, followed by open thoracoabdominal aortic aneurysm repair. During the second operation, the descending aorta was cross clamped along with the preexisting stent graft, and Dacron graft was anastomosed directly to the stent graft using a running 4-0 monofilament suture. The anastomosis site was then covered with a short piece of Dacron graft identical with the stent graft in size to secure hemostasis. We herein discuss our approach in this complex case, focusing on prevention of inadvertent events such as deformation of the preexisting stent graft and unexpected bleeding.</p>
ABSTRACT
Primary cardiac malignant tumors are relatively rare, and their prognosis is poor. We report a patient with sarcoma causing severe mitral regurgitation and stenosis due to rapid and specific infiltration into the mitral valve.
ABSTRACT
We report a case of left internal iliac aneurysm that ruptured into the left common iliac vein and formed an arteriovenous fistula. A 79-year-old man who had general fatigue was admitted to our hospital with a diagnosis of left internal iliac artery aneurysm, left hydronephrosis, dehydration and low renal function. After dehydration and low renal function resolved rapidly by medical treatment, an enhanced computed tomography was performed. This demonstrated a 69 by 67 mm diameter left internal iliac artery aneurysm with an arteriovenous fistula. During the operation, left common iliac artery and left external iliac artery were resected and the stumps sutured. External iliac-external iliac artery bypass was performed. An occlusive balloon catheter was inserted from the left femoral vein and the balloon was dilated to patch the fistula before opening the aneurysm. After clamping the proximal artery the aneurysm was opened. Bleeding from the fistula was controlled by this maneuver and digital compression of the left common iliac vein where was proximal side of fistula. An arteriovenous fistula with a 18 by 3 mm orifice was found between the left internal iliac artery and left common iliac vein. The fistula was closed from the inside of the aneurysm. His postoperative course was uneventful.
ABSTRACT
We report the Lampshade Technique : a new technique using Carbo-Seal Valsalva (Sorin Biomedica, Saluggia, Italy) to facilitate preparation of a composite graft. A Bentall operation and an ascending aorta replacement were performed with a composite graft using a Carbo-Seal Valsalva. This new technique can be considered useful as it can reduce the time required for preparing a composite graft, and create a skirt portion for continuous suturing to prevent bleeding.
ABSTRACT
A 68-year-old man with unstable angina after old myocardial infarction, and Leriche's syndrome was admitted. Coronary angiography found 90% stenosis of the left anterior descending artery (LAD), 99% stenosis of the diagonal branch, 99% stenosis of the right coronary artery (RCA), and 90% stenosis of the 4-posterior descending branch (4 PD). Left circumflex artery (LCX) was diffusely stenotic and small. Aortography revealed complete occlusion of the infrarenal aorta. Due to the risk of limb-threatening ischemia, we planned simultaneous revascularization of myocardium and the lower extremities. Off-pump coronary artery bypass (OPCAB) was performed first. Subsequently Y graft replacement of abdominal aorta was completed. The postoperative course was uneventful and he was discharged on the 14th day after operation.
ABSTRACT
A 71-year-old man was transferred to our hospital because of impending rupture of an abdominal aortic aneurysm (AAA). Preoperative CT scan demonstrated a huge aneurysm of the aortic arch (TAA) associated with an AAA. Emergency coronary angiography revealed 3-vessel disease. One-stage surgery including TAA repair, coronary bypass surgery, and AAA repair was performed to avoid the possibility of rupture of the remaining aneurysms and the risk of ischemic heart diseases. One-stage surgery is a possible approach for patients with severe multivascular diseases.
ABSTRACT
A 16-year-old boy with multiple injuries suffered in a motorcycle accident was admitted to our hospital. On admission, X-ray films showed left hemothorax and bone fractures of the left humerus, thigh bone, and pelvis. Computed tomography of the chest revealed a pseudoaortic aneurysm approximately 6.0cm in diameter at the proximal portion of the descending aorta. Because of multiple severe associated injuries, we considered that conventional aortic repair in the acute phase would be difficult. We therefore performed an endovascular stent-graft treatment 140 days after injury. The postoperative course was uneventful and the pseudoaneurismal sac has confirmed to decrease. Transluminal placement of endovascular stent-graft is a technically feasible method for treatment of traumatic aortic aneurysm. However, because the long-term results are still unknown, we should follow-up carefully, particularly in young patients.
ABSTRACT
An 86-year-old woman was transferred to our hospital because of chest pain and left incomplete paralysis. CT-scan revealed a dissecting aortic aneurysm (DeBakey type 2) 6cm in diameter. Coronary angiography and aortography were perfomed to assess the coronary artery disease and ASO, they showed occluded LAD, 90% stenosis of CX and occluded left external iliac artery. We planned a 1-stage operation. Coronary artery bypass grafting with the beating heart was carried out prior to replacement of the ascending aorta. Then we performed femoro-femoro bypass. The postoperative course was uneventful and the patient was discharged 23 days after the operation.
ABSTRACT
A 50-year-old man was admitted with a fusiform descending thoracic aortic aneurysm measuring 60mm. Chest CT scan revealed porcelain aorta from the aortic arch to the abdominal aorta. Severe calcification found on the descending aortic wall was considered to entail greater risk for conventional aortic repair and reconstruction of intercostal arteries. Therefore endovascular stent grafting was planned. The stent graft was deployed from near the origin of the left subclavian artery to the 10th thoracic vertebral level. Neither paraplegia nor other complication occurred. Endovascular stent grafting may be a safe and effective method for descending thoracic aneurysms with severely calcified aorta.
ABSTRACT
A 65-year-old man suffered abdominal pain and anterior chest pain due to a ruptured abdominal aortic aneurysm (AAA) and acute myocardial infarction. Abdominal CT scanning demonstrated infrarenal AAA measuring 6.0cm in diameter with retroperitoneal hematoma. Coronary angiography was performed revealing total occlusion of the left anterior descending and 90% stenosis in the circumflex coronary artery. The operation was performed immediately after CAG. After median sternotomy, cardioplumonary bypass was initiated using moderate hypothermia (32.0°C). After completion of CABG, AAA replacement using a Y-shaped prosthesis was performed during extracorporeal circulation. Extracorporeal circulation protects the heart from the hemodynamic changes after aortic clamping or declamping during abdominal aortic surgery. Our experience shows that one-stage operation is a feasible option for patients with AAA and coronary artery disease accompanied by impaired left ventricular function.
ABSTRACT
A 51-year-old male, who had undergone aortic valve replacement (BS27A) 13 years ago, was admitted with a sudden onset of cerebral stroke and SVC syndrome. Computed tomography and aortography revealed aneurysmal dilatation and dissection of the ascending thoracic aorta with occlusion of the superior vena cava and the right pulmonary artery. A modified Collins procedure was performed and the postoperative course was uneventful.
ABSTRACT
Since arteriosclerosis is a general progressive disease, an aneurysm of the thoracic aorta is not infrequently complicated by ischemic heart disease. Therefore, assessment of indications of surgical treatment and selection of the surgical procedure and auxiliary procedures on the basis of accurate preoperative evaluation of ischemic heart disease are considered to be very important for improving the results of operations for thoracic aortic aneurysm. Recently. we successfully operated on a 64-year-old patient with a left ventricular aneurysm and a descending aortic aneurysm. One-stage operation was performed by a left thoracotomy approach and partial left heart bypass by draining the pulmonary artery into the femoral artery with mild hypothermia. The approach and the auxiliary procedures employed in this patient are considered to be a useful combination applicable also to one-stage operation for descending aortic aneurysm and coronary artery bypass grafting.
