  • Takayasu`s arteritis is one of chronic inflammatory disease characteristically involving the aorta and it`s major branches. We experienced two surgical cases of Takayasu`s arteritis associated with the stenosis of the descending thoracic aorta. One case was 15 year-old girl and she was admitted because of dyspnea on exertion for 12 months. Aortogram showed the stenosis of the descending thoracic aorta from just below left subclavian artery to the 9th thoracic vetebra. The other case was 10 year-old girl and she was admitted because of URI and hypertension. Aortogram showed narrowing of right innominate artery, but developed collateral circulation, and the stenosis of the descending thoracic aorta near the 9th thoracic vertebra. In each case, bypass graft from the ascending aorta to the abdominal aorta just above the inferior mesenteric artery was performed with satisfactory result.

  • Objectives: To examine the relaxational response to the water extract of Rheum palmatum L. and Rheum undulatum L. on rat thoracic aorta and abdominal aorta. Methods: Segments of thoracic aorta and abdominal aorta obtained from rats immediately after delivery were mounted in organ baths superfused on a polygraph. Results : We found that the thoracic aorta segments responded to the water extract of genus Rheum with a dose-dependent vasorelaxation. At $10^{-4}$ M 5-HT, the maximal contraction force was 93.5% of the maximum KCI-response. The 5-HT induced contractions at $10^{-4}$ M were inhibited by 86.4% and 62.1 % after addition of the high concentrations of R. palmatum root (RPR) and leaf (RPL) and R. undulatum root (RUR) and leaf (RUL). At 10 mg/ml RPR and RUR, the relaxational response at thoracic aorta and abdominal aorta with and without endothelium were 86.4%, 83.2%, 85.8%, and 62.1% of the maximum 5-HT induced contraction. Conclusion: Our result showed that RPL and RUL induced dose-dependent vasorelaxation on rat thoracic aorta and abdominal aorta, and that RPL and RUL roots have more potent effects than the leaves.

  • Aortoesophageal fistula is an uncommon and fatal complication after surgery of aortic aneurysm. A case of aortoesophageal fistula as a complication of synthetis patch aortoplasty for mycotic aneurysm of descending thoracic aorta is described. After 3 months since patch aortoplasty for mycotic aneurysm of descending thoracic aorta this patient visited the emergency room due to melena and hematemesis. After gastrofiberoscopy and computed tomography the patient was taken ot the operating room. The surgical intervention was performed in two steps. Median sternotomy and midline laparotomy were made. Hemashield's Dacron(16mm) bypass between ascending thoracic aorta and infra-renal abdominal aorta was established first. Through the posterolateral thoracotomy false aneurysm and previous Hemashield's Dacron patch of descending aorta were resected. The two ends of the aorta were sutured and esophageal fistula was repaired. The esophageal suture line and the stumps were covered with omental graft. Thirty months later the patient has had no difficulty referable to the aortic surgery.

  • Objective : To examine the inhibition of 5-Hydroxytryptamine(5-HT) induced vasocontraction of the water extract of Acanthopanax senticosus Harms roots (ASR) on rat thoracic Aorta and mesenteric artery with and without endothelium. Methods : Segments of thoracic aorta and mesenteric artery obtained from rats immediately after delivery were mounted in organ baths superfused on a polygraph. Results : We found that the thoracic aorta segments responded to the water extract of ASR with a dose-dependent and concentration-dependent vasorelaxation. 5-HT produced a concentration-dependent contraction of the thoracic aorta and mesenteric artery. At high concentrations of ASR, the inhibition responses were 93.7% (Jang-su), 93.5% (Heok-ryong-kang-sung), 92.8% (Mt. Back-doo), and 83.5% (Yeon-byun) of the maximum 5-HT induced contraction. At high concentrations of ASR, the relaxational response at thoracic aorta and mesenteric artery wi1h endothelium were 95.2% and 94.6%; without endothelium were 93.5% and 92.5% of 1he maximum 5-HT induced contraction. Conclusions : In conclusion, the effect of water extract of ASR had potent inhibition at 5-HT and the effect of ASR in isolated thoracic aorta and mesenteric artery showed dose-dependent inhibition but endothelium-independent response.

  • This is one case report of successful resection of the aneurysm of the thoracic aorta, which det-ected by thoractomy unexpectedly, in the Department of Thoracic Surgery, Hanyang University Hospital. The patient was a 34 years old woman and subjective complaints was not related with the aneurysm. Chest film showed a small round hazy shadow in the left margin of the upper posterior mediastinum. A saccular aneurysm located on the descending thoracic aorta, 7cm distal to the left subclavian artery and arouse from the antero-lateral wall of the aorta. Excision of the saccular aneurysm was performed by cross clamping the descending aorta above and below the aneurysm, and then the defect of the aortic wall was closed by aortorrhaphy with continuous suture. Crossclamping time was required 15 minute. Histopathologically, the wall of the aneurysm consisted of all layers of the arterial wall, that is, intima, media and adventitia. Postoperative course was uneventful and aortogram showed good continuity of the blood flow of the entire aorta.

  • Aneurysms of the descending thoracic aorta can be caused by various etiologies. So, its abrupt rupture leads life-threatening state, it must be operated as soon as possible. Surgical treatment of the descending thoracic aortic aneurysm requires temporary cross-clamping of major artery. The obligatory occlusion of the descending thoracic aorta during management causes proximal arterial hypertension and distal arterial hypotension. The former may leads to left ventricular failure, or cerebrovascular accident, whereas the latter may leads to spinal cord ischemia or renal injury. Some have recommended insertion of temporary shunt around the occluded descending aorta to prevent above problems. Still others would favor expeditious operation employing simple aortic occlusion during the repair of the descending aorta. Recently we had experienced two cases of dissecting aneurysms of descending thoracic aorta which performed aortoplasty with Gore-Tex conduit under simple aortic occlusion. The one was 34-year-old female patient with traumatic dissecting aortic aneurysm [5 em X 5 cm] on the descending thoracic aorta distal to the origin of the left subclavian artery and the other was 58-year-old female patient with atherosclerotic dissecting descending thoracic aortic aneurysm [6 cmX7 cm] and diffuse abdominal aortic aneurysms [3X5 cm]. Both patients performed standard left posterolateral thoracotomy. After the aneurysmal sac was mobilized, occluding vascular clamps were placed on the transverse aorta proximal to the origin of the left subclavian artery, and on the distal descending aorta without adjuvant bypass procedures for 31 and 32 minutes, respectively, and the aneurysmal sac was repaired with 18 mm ringed Gore-Tex conduit graft. Both patients postoperative courses were uneventful.

  • The rupture of the aorta commonly follows major blunt trauma to the thorax. It has markedly increased in recent years, paralleling the rising number of vehicular accidents. The most frequent site of rupture is the area of the isthmus, with the ascending aorta second. The diagnosis of the condition from clinical data is difficult, and aortography is used whenever aortic tear is suspected. We are presenting a case of patient who had intimal tearing of the thoracic aorta with multiple injuries. The patient underwent surgical repair 28 days after injury with left heart [LA-Femoral artery] bypass.

  • Bronchopulmonary sequestration (BPS) is a rare congenital malformation of the lower respiratory tract. Most intralobar BPSs are provided with an arterial blood via the thoracic or abdominal aorta but such a supply is rarely found in patients older than 50 years. We report a case of an intralobar BPS with a dual arterial supply from the celiac artery and thoracic aorta in a 50-year-old man presenting with a respiratory tract infection and haemoptysis. To our knowledge, this is the first case report of a BPS supplied by the celiac artery and thoracic aorta in a 50-year-old man.
