Intramural hematoma of the aorta (IMH) is the precursor or a variant of a classic aortic dissection where hemorrhage occurs within the aorta wall in the absence of an initial intimal tear. IMH has a high rate of mortality and morbidity. The optimal therapy for IMH is uncertain, yet the involvement of the ascending aorta is usually considered as an indication for surgery due to the associated risk of rupture or cardiac tamponade. We report here on a case of a 71-year-old man who presented with syncope. Because of misdiagnosis, he underwent computed tomography (CT) after 5 hrs from arriving to the ER. Computed tomography of the aorta revealed intramural hematoma of the ascending aorta with cardiac tamponade. He also had vascular complications such as acute renal failure and visceral ischemia. We performed emergency graft replacement of the total arch and ascending aorta. He was discharged without complication on postoperative day 14.

Endovascular stent grafting is regarded as a promising alternative approach to open surgical repair for treating various aortic diseases in high risk patients. We report here on a case of a 79-year-old female who underwent endovascular stent-graft insertion in the ascending aorta for treating a complicated ascending aortic rupture that occurred secondary to radiation necrosis during the treatment of recurrent breast cancer.

Cases of undifferentiated pleomorphic sarcoma of the thoracic aorta are rare, and usually present with embolic events, renovascular hypertension, or back pain. Mural-based undifferentiated pleomorphic sarcomas that present as ruptured saccular aneurysms are extremely rare and are difficult to differentiate from mycotic aneurysms or penetrating atherosclerotic ulcers. Herein, we report a case of histopathologically proven undifferentiated pleomorphic sarcoma arising from the wall of the descending thoracic aorta that manifested as a mass after thoracic endovascular aortic repair for the treatment of a ruptured saccular aneurysm. We present findings obtained by CT and PET to provide helpful information for the accurate diagnosis and appropriate treatment of future cases.

Background: Conventional ascending aortic cross clamping is often limited. This study was carried out to evaluate the safety and efficacy of an endovascular aortic clamping technique with an intraaortic balloon catheter. Material and Method: From April 2004 to January 2007, surgery with endoaortic clamping was performed in seven patients. A retrograde access perfusion (RAP) catheter was used in six patients and a Pruitt's balloon catheter in two patients. The indication for the operation was a retrosternal pseudoaneurysm of the aortic root in six patients, diffuse calcification of the ascending aorta with aortic regurgitation in 2 patients and an atrial septal defect in one patient. Five patients had at least two prior cardiac surgeries. Result: Successful insertion of the catheter and endoaortic clamping was achieved in all patients. Conclusion: The endovascular aortic clamping technique with a balloon catheter was a useful alternative method for patients in whom conventional cardiac surgery was limited.

Background: Open surgical repair of abdominal aortic aneurysms was initiated by Dubost in 1952. Despite the rapid expansion of percutaneous endovascular repair, open surgical repair is still recognized for curative intent. We retrospectively analyzed surgical outcome, complications, and mortality-related factors for patients with abdominal aortic aneurysms over a 6 year period. Material and Method: We analyzed 18 patients who underwent surgery for abdominal aortic aneurysms between March 2002 and March 2008. The indications for surgery were rupture, a maximal aortic diameter >60 mm, medically intractable hypertension, or pain. Result: The mean age was $66.6{\pm}9.3$ years (range, $49\sim81$ years). Twelve patients (66.7%) were males a 6 patients were females. Extension of the aneurysm superior to the renal artery existed in 6 patients (33.3%), and extension to the iliac artery existed in 13 patients (72.2%). Five patients (27.8%) had ruptured aortic aneurysms. The mean maximal diameter of the aorta was $72.2{\pm}12.9$ mm (range, $58\sim109$ mm). Surgery was performed by a midline laparotomy, and 6 patients underwent emergency surgery. The mean total ischemic time from aorta clamping to revascularization was $82{\pm}42$ minutes (range, $35\sim180$ minutes). The mortality rate was 16.7%; the mortality rate for patients with ruptured aneurysms was 60%, and the mortality rate for patients with unruptured aneurysms was 0%. The postoperative complications included one each of renal failure, femoral artery and vein occlusion, and wound infection. The patients who were discharged had a long-term survival of $34{\pm}26$ months (range, $4\sim90$ months). Rupture and emergency surgery had a statistically significant mortality-related factor (p < 0.05). Conclusion: Emergency surgery for ruptured aortic aneurysms continues to have a high mortality, but unruptured cases are repaired with relative safety. Successfully operated patients had long-term survival. Even though endovascular aortic repair is the trend for abdominal aortic aneurysms, aggressive application should be determined with care. Experience and systemic support of each center is important in the treatment plan.

Characterized by unique phenotypic features such as aortic aneurysm/dissection, hypertelorism, bifid uvula/cleft palate and generalized tortuosity in the arterial system, Loeys-Dietz syndrome is a newly described aggressive connective tissue disorder associated with mutation in the gene encoding transforming growth factor-$\beta$ receptor type I or type II. Some phenotypic manifestations of Loeys-Dietz syndrome overlap with those of Marfan syndrome or Ehlers-Danlos syndrome type IV. However, due to its more malignant pathophysiologic nature, physicians should be alert to Loeys-Dietz syndrome. High suspicion, early diagnosis, preventive surgery and serial imaging assessments are warranted for optimal management of Loeys-Dietz syndrome. We present here a case of a young patient with Loeys-Dietz syndrome who had aortic rupture, bifid uvula and hypertelorism. We also present a review of the medical literature.

Between March 1963, and December 1994, fifty-three patients with a ruptured aneurysm of sinus of Vasalva(RSV) were operated. The RSV originated from the right coronary sinus in 43 patients(81%), from the non coronary sinus in 7 patients(13%), and from combined sinuses in 2 patients. The RSV from the right coronary sinus mainly drained to the right ventricle(81.4%), and the RSV from the non coronary sinus mainly drained to the right atrium(71.4%). Recently, we are using patch to repair the RSV through a double approach. During the operation, concomitant . procedures were performed; 32 Patch repairs of VSD, 14 aortic valvuloplasty, 10 aortic valve replacement, 2 tricuspid valvuloplasty, and one Bentall's procedure. During the follow up period between 1 and 31 years(mean 8 years, 94% follow up), there were 2 late deaths and 14 late complications. Actuarial 10-year survival rate .was 95%, and 10-year actuarial freedom from late event was 53 %. Factor analysis revealed that the combined SBE is a risk factor of late event. Actuarial freedom from failure of aortic valvuloplasty was 55% at 9 years. Although surgical repair of RSV achieved excellent long term survival, aortic regurgitation and endocarditis revealed significant risk factor in long-term results. Therefore, more attention should be required in patients of RSV associated with aortic regurgitation or endocarditis.

Aortic disease usually recurs after aortic surgery in the form a new aneurysm distal to the previous operation site, and finding a penetrating atherosclerotic ulcer proximal to the previous operation site has rarely been reported. We report here on a case of successful patch repair of a ruptured penetrating ulcer in the distal aortic arch, and this developed late after replacement of the descending thoracic aorta.

Aortic dissection refers to the separation of the aorta into a true and false lumen as the medial membrane of the aorta is torn along the long axis due to a high aortic pressure when a minute rupture occurs in the aortic lining. The mortality rate is very high, and aortic dissection occurs 2~5 times more in men than women. The prevalent age range is 50~70 years old. In this case, the authors experienced a diagnosis of aortic dissection that occurred in a young woman in her 30s, which does not occur frequently. In the process of tracking severe aortic regurgitation, aortic valve prolapse was initially suspected. We report this case because aortic dissection could be diagnosed by observing the intimal flap of the ascending aorta in the process of confirming this suspected part.
