Penetrating atherosclerotic ulcer involving the aortic arch has rarely been reported on in the literature. Acute rupture of a penetrating atherosclerotic ulcer involving the distal arch and the proximal descending thoracic aorta was found in a 78-year-old male, and he originally presented with acute-onset shoulder pain and hoarseness. Patch repair of the perforated arch and the proximal descending thoracic aorta was successfully done under total circulatory arrest.

We report hereon a case of double bypass of the esophagus and descending thoracic aorta for the treatment of esophagopleural fistula and aortopleural fistula due to an infected aortic aneurysm after esophageal rupture. A 48 year old man was diagnosed as having esophageal rupture after an accidental explosion. Although he had been treated by esophageal repair and drainage at another hospital, the esophageal leakage could not be controlled and subsequent empyema developed in the left pleura. Further, bleeding from the descending thoracic aorta had developed and he was managed with endovascular stent insertion to the descending thoracic aorta. He was transferred to our hospital for corrective surgery. We performed esophago - gastrostomy via the substernal route, without exploring posterior mediastinum and we let the empyema resolve spontaneously. While he was being managed postoperatively Without any signs and symptoms of infection, sudden bleeding developed from the left pleural cavity. After evaluation for the bleeding focus, we discovered an Infected aortic aneurysm and an aortospleural fistula at the stent insertion site. We performed a second bypass procedure for the infected descending thoracic aorta from the ascending aorta to the descending abdominal aorta via the right pleural cavity. We found leakage at the distalligation site during the immediate postoperative period, and we occluded the leakage using a vascular plug. He discharged without complications and he is currently doing well without any more bleeding or other complications.

Background: The conventional method of aortic cross-clamping is very difficult and increases the risk of cerebral infarct due to embolism of the calcified aorta in these patients. Accordingly, we analyzed our experience with 11 cases of ascending aorta and aortic valve replacement with hypothermic circulatory arrest. Materials and Methods: From January 2002 to December 2009, 11 patients had ascending aorta and aortic valve replacement with hypothermic arrest at our hospital. We performed a retrospective study. Results: There were 5 males and 6 females, with a mean age of 68 years (range, 44 to 82 years). Eight patients had aortic stenosis, and 3 patients had aortic regurgitation. An aortic cannula was inserted into the right axillary artery in 3 patients and ascending aorta in 6 patients. Two patients with aortic regurgitation had a remote access perfusion catheter inserted though the right femoral artery. The mean cardiopulmonary bypass time was 180 minutes (range, 110 to 306 minutes) and mean hypothermic circulatory arrest time was 30 minutes (range, 20 to 48 minutes). The mean rectal temperature during hypothermic circulatory arrest was $21^{\circ}C$ (range, $19^{\circ}C$ to $23^{\circ}C$). No patient had any new onset of cerebral infarct or cardiovascular accident after surgery. There was no hospital mortality. Early complications occurred in 1 patient who needed reoperation due to postoperative bleeding. Late complications occurred in 1 patient who underwent a Bentall operation due to prosthetic valve endocarditis. The mean follow-up duration was 32 months (range, 1 month to 8 years) and 1 patient died suddenly due to unknown causes after 5 years. Conclusion: Patients with a calcified aorta can be safely treated with a technique based on aorta and aortic valve replacement under hypothermic circulatory arrest.

We experienced a case of traumatic aneurysm of descending thoracic aorta by an automobile accident. The patient was 23-year-old-male with a traumatic aortic aneurysm [6x12cm] on the descending thoracic aorta just distal to the origin of the left subclavian artery. Exposure was obtained through a left posterolateral thoracotomy incision in the fourth intercostal space and then partial femoro-femoral cardiopulmonary bypass was established.After aortic cross- clamping, the aneurysmal sac was opened and repaired with interposition of Dacron vascular graft and aortic cross-clamping period lasted for 100 minutes. Postoperative bleeding and vocal cord paralysis were complicated, but bleeding was controlled by reoperation and vocal cord paralysis was improved. Follow up was continued for 14months and postoperative course was uneventful.

Dissecting aortic aneurysm is a disease which is characterized by hemorrhagic intramural seperation of aortic wall and extension for varlng distances proximally, distally, or both from the site of the intimal tear. Most aortas show some type of medial degeneration most commonly described as cystic medial necrosis. DeBackey classified this disease according to involved aorta and site of intimal tear to 3 basic types, such as type I, II and III. Type III is defined that dissecting process arrises in the descending thoracic aorta just distal to origin of the left subclavian artery and extends distally for a varing distance. We expirienced a case of dissecting aneurysm, type III of DeBackey's classification which dissecting process is limited to the descending thoracic aorta in the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. This patient was 40 year old woman and she had suffered from intermittent sharp back pain for 3 years .before admission. Excision of the aneurysm and Dacron graft were placed successfully under the left atrio-femoral bypass with artificial pump. The hospital course was uneventful.

Aortobronchial fistula (ABF) involves the formation of an abnormal connection between the thoracic aorta and the central airways or the pulmonary parenchyma and is associated with an increased risk of mortality. An ABF typically manifests clinically with symptoms of hemoptysis, and currently, there is a lack of defined guidelines for its treatment. Here, we report the cases of two patients who suffered from recurrent hemoptysis due to ABF with pseudoaneurysm. We propose that removal of the aorta with concomitant lung resection and coverage of the aorta using the pericardial membrane is a definite treatment to lower recurrence of ABF and persistent infection.

Undifferentiated pleomorphic sarcoma (UPS) arising from the descending thoracic aorta is a rare type of tumor. To our knowledge, only a few cases have been reported in the literature. We present computed tomography (CT) and magnetic resonance imaging findings of a 43-year-old male patient with undifferentiated pleomorphic sarcoma of the descending thoracic aorta, which showed enhancement on only magnetic resonance imaging (MRI). MRI with contrast enhancement may be useful in differentiating an aortic tumor from atherosclerotic disease.

Aortic dissection is a challenging disease and the causes of that are well-known. Blunt chest trauma is one of the causes of aortic dissection. In such cases, nearly all cases involves the isthmic portion of descending aorta, but ascending aorta is involved in about 10. We experienced a patient who had ascending aortic dissection due to automobile accident and who showed spontaneous rupture of the aorta during operation. In this case, after installation of aortic line via left femoral artery, ascending aorta ruptured and a large amount of blood gushed out, which was suckered by cardiotomy sucker. A little delay of cardiopulmonary bypass may cause the fatal outcome in such a case because the bleeding from aorta is too much to be controlled. Fortunately, we controlled the bleeding with cardiopulmonary bypass and got the good outcome of this patient by interpositioning the vascular graft. One should suspect the possibility of aortic dissection in blunt chest trauma, and prepare all the facilities against bleeding due to rupture.

A Case of thoraco-abdominal aortic aneurysm involving from the lower descending- thoracic aorta to bifurcation of abdominal aorta into both common iliac artery is presented in special view-point of its surgical technic and postoperative complication. Operative technic is the most popular method of Dr. De Bakey's shunt of Dacron which is bridging thoracic aorta to terminal abdominal aorta primarily as temporary shunt but after anastomosing the individual hranch of left Renal, Celiac, Sup. meseateric and right Renal artery to corresponding part of the Dacron tube, the Dacroa graft is fixed as permanent graft in stead of excised thoraco-abdominal aorta. The patient died of acute renal failure and increasing evidence of CNS damage due to respiratory acidosis on 6th postoperative day hut this report will he a good experience in respect of further progress of aortic surgery in Korea.

Aneurysm of the Aorta is a grave disease mostly producing disabling symptoms and ultimate death by rupture and hemorrhage without surgical intervention. The author recently experienced one case of surgical correction of descending thoracic aortic aneurysm treated with excision of the aneurysm and replacement of Dacron artificial vessel under temporary external by pass technique in November, 10th, 1975. 9mm internal diameter arterial cannula was inserted into upper and below the aneurysm. Bypass time was about 1 hour. The case was 35 years old women who had small egg sized saccular aneurysm in the upper third of the descending thoracic aorta involving the 1t. subclavian artery. Histopathological diagnosis was arteriosclerotic. Immediate postoperative course had been uneventful except low pressure and pulse of the left arm. The follow-up was possible up to date about 3 months. The patient has been doing well with ordinary activities except mild left chest discomfort.
