We report an unusual case of delayed bleeding after open surgical repair of a thoracoabdominal aortic aneurysm. A 79-year-old man developed a massive retroperitoneal hematoma 49 days after Crawford type III thoracoabdominal aorta replacement. During emergency surgery, a tear was found in the prosthetic vascular graft caused by a sharp bony spur arising from the second lumbar vertebral body. This rare, but potentially lethal, complication indicates that attention should be paid to sharp bony structures during open repair of the descending aorta.

Still a lethal injury, traumatic rupture of thoracic aorta occurs more frequently than we expect and comprises significant part of causes of deaths by blunt trauma. We recently experienced a thoracic aortic rupture accompanied by multiple injuries including pericardial and interatrial septal rupture and myocardial contusion in a patient who had been injured in a fall accident. Literatures are reviewed with the concern of early diagnosis, surgical technique and the result of operation.

Background: Background: Computed tomography (CT) is the main tool for detecting abnormalities of the thoracic aorta, but conventional CT only shows the cross-sectional images. These CT images have some limitations fo accuratly measuring the thoracic aortic diameters at various levels. Multidetector computed tomography (MDCT) overcomes these limitations. We measured the thoracic aortic diameter perpendicular to the loop-shaped thoracic aortic course and this was studied in relation to age, gender, height, weight, the body surface area, the body mass index and the presence of hypertension. Material and Method: Thirty hundred thirty one patients (males: 141 patients and females: 190 patients) who had no abnormalities of the thoracic aorta were investigated using MDCT aortography. They were divided into three age categories: 20~39 years old, 40~59 years old and over age 60. The image was reformed with multiplanar reconstruction and the diameter of the aorta was measured perpendicular to the aortic course at 5 anatomic segments. Level A was the mid-ascending aorta, level B was the distal ascending aorta, level C was the aortic arch, level D was the aortic isthmus and level E was the mid-descending aorta. Result: The mean age was 49.5 years old for males and 54.9 years old for females (p<0.05). The mean diameter of the thoracic aorta at level A was 31.1 mm, that at level B was 30.2 mm, that at level C was 26.5 mm, that at level D was 24.0 mm and that at level E was 22.6 mm. The diameters at all the levels were gradually increased with age. Hypertensive patients had larger diameters than did the non-hypertensive population. There was a positive correlation between the ascending aortic diameter (levels A&B) and height and the body surface area, but there were no statistical differences at the aortic arch (level C) and the descending aorta (levels D&E). There were no statistical differences of the weight and body mass index at all levels. Conclusion: The diameters of the thoracic aortas were directly correlated with gender, age and hypertension. Height and the body surface area were only correlated with the ascending aorta. Weight and the body mass index have no statistical difference at all levels. We measured the age related thoracic aortic diameters and the upper normal limits and we provide this data as reference values for the thoracic aortic diameter in the Korean population.

Endovascular treatment of the aortic aneurysm with a stent graft is rapidly evolving. We describe here a case of hybrid TEVAR (thoracic endovascular aortic repair) in which the stent grafts were placed in the aortic arch after debranching of the arch vessels. The patient had undergone ascending aorta replacement for acute type I aortic dissection 2.5 years earlier. The aneurysmal change of the distal dissection progressed with time. A provisional bypass surgery from the ascending aorta to the innominate artery and left carotid artery was performed and then stent grafts were inserted via an antegrade route that covered the whole aortic arch and proximal descending thoracic aorta.

We have examined the relaxational response to the water extract of Rheum palmatum L.(ERP) and water extrc alcohol processed Rheum palmatum L.(ARP) in isolated thoracic aorta from sprague dawley (SD) rat. Rat thoracic aort investigated in vessel segments suspended for isometric tension recording by polygraph. Responses to ERP and ARP investigated in vessels precontracted with 5-hydroxytryptamine(5-HT). We found that the thoracic aorta segments respo to ERP and ARP with a dose-dependent vasorelaxation. We found that ; The thoracic aorta segments responded to I and ARP with a dose-dependent vasodilation. The 5-HT induced contraction at 10/sup -4/M were inhibited by 71.7% and a: after addition of the 0.01 g/mL water extract of ERP and ARP. The 5-HT induced contraction at 10/sup -4/M were inhibite 100% after 10/sup -3/M emodin. The concentration of emodin was 0.027% and 0.098% in ERP and ARP. In condusion, ERP ARP induced relaxation in the isolated rat thoracic aorta were composed of dose-dependent relaxation. and it has pi vasodilation.

We have experienced two cases of ascending aorta aneurysm with aortic regurgitation in Marfan`s syndrome. There were abnormal findings in cardiovascular system associated with abnormalities of skeletal systems. They had total replacement of the ascending aorta and aortic valve with Bjork-Shiley`s aortic valve composite graft and reimplantation of coronary ostia on the graft. Their postoperative courses were uneventful and discharged with good clinical results for follow up.

Aortopulmonary septal defect is rare congenital heart disease. An 8-year-old girl was diagnosed as a ventricular septal defect with patent ductus arteriosus at Department of Thoracic and Cardiovascular Surgery of Chungnam National University Hospital. On operation, the defect was confirmed as an aortopulmonary septal defect [Type I], anomalous origin of right pulmonary artery from aorta [Type Ill] and patent ductus arteriosus. The defect was repaired anatomically with cardiopulmonary bypass. But she was not survived because of uncontrollable bleeding from aorta.

Aneurysm of the Aorta is a grave disease mostly producing disabling symptoms and ultimate death by rupture and hemorrhage without surgical intervention. Aneurysm of the thoracic aorta is more common in arteriosclerosis than syphilitic origin,since the incidence of cardiovascular syphilis has been reduced significantly in recent decades and the life span of population has increase. We have experienced a case of luetic aneurysm of aortic arch without pulse in tile left arm which was succesfully treated by surgical intervention.

In patient with severe adhesion between lung and aorta, there is some limitation in approaching the distal arch or descending thoracic aorta through the usual left thoracotomy. We report a case of a successfully managed distal arch and descending thoracic aortic aneurysm through the median sternotomy without any manipulations of the lung in a 66 year old man who presented hemoptysis.

Eight patients received operation for ascending aortic aneurysm and aortic regurgitation associated with Marfan`s syndrome from January 1984 to July 1986 at Seoul National University Hospital. The patients` age ranged from 29 to 51 years [mean 37.3 years]. Five patients were male and three were female. All of them showed some stigmata of skeletal system in Marfan`s syndrome. Three patients had dissecting aneurysm and five patients had fusiform aneurysm of ascending aorta. Two patients had concomitant fusiform aneurysm of abdominal aorta. All patients showed aortic regurgitation of grade III to IV. One patient received insertion of intraluminal ringed graft and resuspension of aortic valve, and seven patients received modified Bentall operation [Carol`s method]. There was no hospital death and all showed functional improvement in the 7.4 patient-years follow-up period.
