  • To investigate the difference of contractile mechanism between KCI and phenylephrine-induced contraction, we observed effects of $Ca^{2+}$ antagonists and protein kinase inhibitors on aorta contraction of rats. Verapamil dose-dependently inhibited the contraction induced by KCI and phenylephrine, the inhibitory effect of verapamil was more potent in KCI-induced contraction than phenylephrine-induced contraction. Econazole and TMB-8 significantly inhibited CKI-induced contraction but did not inhibit phenylephrine-induced contraction. Staurosporine dose-dependently inhibited both KCI and phenylephrine-induced contraction. Genistein and calmodulin antagonists (W-7 and trifluoperazine) also inhibited both contraction in a dose dependent manner. However, the inhibitory effects of genistein and calmodulin antagonists were more potent in phenylephrine-induced contraction than KCI-induced contraction. These results suggest that involvements of $Ca^{2+}$ channel and protein kinase in rat aorta contraction were dependent on agonist causing aorta smooth muscle contraction.

  • 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.

  • 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.

  • Aortic thrombi are important because it can cause the central and peripheral embolizations. Aortic thrombi can occur anywhere in the aorta but extremely rare in ascending aorta without atherosclerosis, aneurysm, cardiosurgical or traumatic state. Systemic sclerosis (SSc) is an autoimmune disorder of connective tissue and it can involve multisystem. Enhanced coagulation pathways, decreased fibrinolysis, and endothelial dysfunction probably contribute to vascular events in SSc. We report a case of a highly mobile thrombus in the ascending aorta, presented as an acute embolic stroke in the patient with systemic sclerosis. Surgical removal was performed to prevent recurrent embolic events.

  • The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resources. We carried out to develop a traditional functional beverage by using hot-water extraction of 4 medicinal plants(Polygonatun sibiricum, Ophiopogonis radix, Lycii fructus, Schizandriae fructus) and we examined the effects of drink on physiological function in aorta relaxation. Thus, the effect of developed beverage on phenylephrine induced contraction of isolated rat thoracic aorta. Contractile force was measured with force displacement transducer under 1.5g loading tension. Brix, pH and titratable acidity of developed drink were 9.5%, 3.3 and 0.22%. The approximate nutritional composition of beverage was carbohydrate, 5.98%, crude protein, 0.70%, crude fat, 0.20% and crude ash, 0.20%. Developed beverage contained K(4.00 ㎎%), Na(3.68 ㎎%), Ca(2.54 ㎎%), Mg(1.60 ㎎%) and Fe(0.29㎎%). The contraction forces by injection of phenylephrine in isolated thoracic aorta were significantly low in each experimental groups compared with control groups, These results that developed drink with medicinal plants can be used as a functional material to decrease aorta contraction.

  • 대동맥벽내 혈종은 진성 대동맥박리증과 구별되는 질환으로 아직 정확한 예후나 치료지침이 알려져 있지 않다. 저자들은 57세 여자환자에서 상행대동맥에 발생한 대동맥 벽내 혈종 1례를 수술 치험하였다. 환자는 질식감과 함께 심한 전흉부동통이 견갑골간으로 전파되는 것이 주소였다. 술전 흉부 전산화 단층왈영에서 흉부대동맥전체와 복부대동맥 일부의 대동맥 벽내에 초생달 형태의 혈종이 관찰되었고, 내벽의 파열 은 관찰되지 않았다. 저자들은 완전순환정지와 역행성 뇌 순환하에서 상행대동맥 치환술을 시행하였다. 우측관상동맥입구 의 손상이 있었으나 복재정 맥을 이용한 우회문합술로 수술하였다. 환자는술후4주만에 퇴원하였으며, 창상감염, 심낭삼출액 등의 합병증외에는 심각한 합병증은 없었다.

  • A 67-year-old female patient was treated with conventional total arch replacement and insertion of a stented elephant trunk (SET) graft into the descending thoracic aorta for acute DeBakey type I aortic dissection at one time. She had been treated with right coronary artery stent insertion for acute myocardial infarct 4 days earlier, and at that time, she was diagnosed with acute DeBakey type I aortic dissection from the ascending aorta to the suprarenal artery based on trans-esophageal echocardiography and aorta computed tomography. Through a median sternotomy, we inserted the SET graft through the opened aorta to the descending aorta. We also performed anastomosis between the proximal stented graft and the distal aortic arch, and then performed total arch replacement. For acute DeBakey type I aortic dissection, we report total arch replacement with insertion of a SET graft as a combination of conventional surgery and the interventional technique.

  • Authors report a case of a painless acute dissecting aneurysm of the descending aorta in a patient who presented with unexplained hypotension followed by simultaneous paraplegia and right arm monoparesis. To our knowledge, case like this has not been reported previously. Magnetic resonance imaging of the brain and spine revealed hemodynamic cerebral infarction and extensive cord ischemia, respectively. Computerized tomography angiography confirmed a dissecting aneurysm of the descending aorta. The cause of the brain infarction may not have been embolic, but hemodynamic one. Dissection-induced hypotension may have elicited cerebral perfusion insufficiency. The cause of cord ischemia may be embolic or hemodynamic. The dissected aorta was successfully replaced into an artificial patch graft. The arm monoparesis was improved, but the paraplegia was not improved. In rare cases of brain and/or spinal cord infarction caused by painless acute dissecting aneurysm of the aorta, accurate diagnosis is critical because careless thrombolytic therapy can result in life-threatening bleeding.

  • This is a case report of successful surgical correction of coarctation of the aorta associated with the patent ductus arteriosus and the persistent left superior vena cava. The patient was a 15 year old girl and congenital heart anomaly was suspected at the sixth month after birth. Afterward there has been no embarrassing symptoms until the day of operation except slight dyspnea on exertion, The diagnosis of coarctation of the aorta and the patent ductus arteriesus detected by physical signs and X-ray studies including aortography. In the first place, coarctation of the aorta was corrected with following procedure: partial resections of the aortic wall just above and below the coarctating line of the aorta and removal of diaphragmatic structure of coarctation performed by. cross clamping aorta above and below coarctation, and then the defect of the aortic wall was closed by lateral aortorrhapic suture with atraumatic needle 3-0 silk continuously [Fig. 6]. In the second place, the patent ductus arteriosus was closed with double ligation method. The persistent left superior vena cava left as it has been, because there has been no evidence of hemodynamic abnormal shunt. After operation, excellent result was obtained; blood pressure in the upper and lower extremities was normalized and subjective complains of hypertension in the upper extremity was disappeared.
