The effect of SKF S25A on SNP-, Ach-, or Pinacidil-Induced Relaxation in the Aorta of Rat (SKF 525A가 휜쥐의 대동맥에서 Sodium nitroprusside, Acetylcholine, Pinacidil에 의한 이완반응에 미치는 효과)

  • TEA, glibenclamide, L-NAME and SKF 525A-induced contraction were investigated using acetylcholine, sodium nitroprusside (SNP, NO donor) and pinacidil (ATP sensitive $K^{+}$ channel opener) in rat abdominal and thoracic aorta. The relaxant effects of acetylcholine, SNP and pinacidil were not different in the abdominal aorta and in the thoracic aorta. Acetylcholine-induced relaxation was dependent on endothelial cell, but pinacidil was independent endothelia cell. In the presence of TEA, glibenclamide, L-NAME, mepacrine and SKF 525A, acetylcholine and SNP did not change, but pinacidil-induced relaxation was significantly reduced in presence of glibenclamide, which is ATP sensitive $K^{+}$ channel blocker. SKF 525A, which is inhibitor of cytochrome P$_{450}$ dependent epoxygenase, partially inhibited the pinacidil-induced relaxation. These results indicate that the pinacidil-induced relaxation may be mediated by ATP sensitive $K^{+}$ channel and partially by EETs, which is produced by cytochrome P$_{450}$ dependent epoxygenase.enase.

  • Twelve patients underwent surgical interventions for aortic aneurysms consecutively from September 1986 to September 1990 in the Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. They were all men ranging in age from 25 to 68 years with the mean age of 48 years. Five patients of them had aneurysms involving ascending aorta, one aneurysm involving both ascending and descending aorta, four aneurysms involving descending thoracic aorta, and the others had aneurysms involving abdominal aorta. According to morphological classification, six cases of them were in dissection and the others in fusiform aneurysms. All the cases were pathologically true aneurysms and four of them were in acute status. According to causal classification, seven patients of them had atherosclerosis, three cystic medial necrosis, and the others had syphilis and trauma respectively. Six patients with ascending aortic aneurysm had annuloaortic ectasia with aortic regurgitation and underwent ascending aortic graft and aortic valve replacement[Bentall`s operation]. The others with descending thoracic and abdominal aortic aneurysms underwent Dacron graft replacement. Both hemorrhage necessitating reopening of the chest and wound dehiscence were observed in three patients and hoarseness in one patient. Cerebrovascular accident occurred three and a quarter years postoperatively in one patient and he died two days later. The others were followed up via OPD and have been doing well postoperatively.

  • Descending thoracic aorta to femoral artery bypass has been used as a remedial operation after aortic or axillofemoral graft failure or graft infection and other intra-abdominal pathologies not amenable to standard aortofemoral revascularization. It can avoid abdomen approach and has been known as a durable procedure with excellent long-term patency. We reported descending thoracic aorta to femoral artery bypass grafting for primary revascularization in a 55-year-old male with hostile abdominal conditions.

  • 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.

  • Nutcracker syndrome is a phenomenon that the left renal vein (LRV) is pressed between the superior mesenteric artery (SMA) and the aorta. Clinical characteristics include gross or microscopic hematuria, orthostatic proteinuria, abdominal pain, and back pain. It occurs due to LRV squeezing caused by narrowed aortomesenteric angle. SMA syndrome is a disease that the third part of the duodenum is prone to intestinal obstruction by narrowed angle between the SMA and the abdominal aorta. Clinical symptoms include postprandial abdominal distension, epigastric pain, nausea, and vomiting. SMA syndrome and nutcracker syndrome have common features that result from narrowed aortomesenteric angle. However, it is very rare for both syndromes to occur simultaneously, so the two syndromes are regarded as separate diseases. This is a report on a case of nutcracker syndrome with SMA syndrome in a child who presented gross hematuria, recurrent abdominal pain and vomiting. To our knowledge, nutcracker syndrome simultaneous with SMA syndrome has not been previously reported in pediatric patient, especially with an exhibition of gross hematuria. This case suggests that the simultaneous presence of SMA syndrome with the same pathogenesis needs to be considered when nutcracker syndrome is suspected in pediatric patients with hematuria.

  • We present a case of ruptured abdominal aortic aneurysm caused by blunt injury. The patient was 23-year-old soldier injured by a motor vehicle accident. Injuries sustained a contused abdominal aorta. At the time of aortic repair, the involved segment formed huge pseudoaneurysm, and which had intimal tear. Aorto-iliac graft replacement was carried out with a woven-dacron Y-graft prosthesis, which restored satisfactory circulation to both lower limbs. The postoperative course was uneventful.

  • From February 1985 to February 1993, 18 operations were performed in 17 patients for treatment of aneurysmal disease [n=12] and/or dissection of the ascending aorta [n=6]. The ages ranged from 26 to 69 years [mean 44.3 $\pm$ 11.0 years].The proposed operations include composite graft replacement of aortic valve and ascending aorta with coronary reimplantation in 11, graft replacement of ascending aorta alone in 5, aortic valve replacement and supracoronary graft replacement in 1 and ascending aorta to abdominal aorta bypass with thromboexclusion of descending aorta in one patient. Both Bentall [n=6] and Cabrol [n=5] technique were utilized for reimplantation of coronary arteries.Concomitant replacement of aortic arch and arch vessel reconstruction was necessary in two patients. Hypothermic circulatory arrest was utilized in 6 patients. Recently, four patients were managed on warm blood continuous cardioplegia via retrograde route. There were no operative deaths. No significant postoperative complications were noted. Postoperative follow up was complete in 15 patients from 1 month to 72 months. Redo operation was necessary in one patient who had suffered from distal recurrence of dissection 5 years after successful Bentall operation. The other patients are all in excellent clinical condition. From our early experience with those 17 cases, we assume that satisfactory operative result could be achieved with a variety of surgical technique including hypothermic circulatory arrest. In addition, continuous perfusion of warm blood cardioplegia via retrograde route is supposed to be beneficial in selected cases.

  • We experienced 20 patients with Takayasu`s disease who required 22 surgical procedures for critical arterial stenoses, aneurym of descending thoracic aorta, and aortic regurgitation from 1986 to 1993.Five patients had type I arteritis, seven patients had type II , seven patients had type III, and one patients had type IV.15 patients were female and 5 patients were male.Patients` ages ranged from 17 to 47 years and mean age was 29.1 years. The surgical procedures were as follows;autotransplantations of kidney[3], aortic valve replacements[2], ascending aorta-bilateral internal carotid artery bypasses[2], unilateral renal artery bypasses[2], bilateral renal artery bypasses[3], replacement of descending thoracic aorta[1], ascending aorta-abdominal aorta bypass[1], ascending aorta-right internal carotid artery bypass[1], ascending aorta-right internal carotid artery and left subclavian artery bypass[1], left common carotid artery-left-subclavian artery bypass[1], pulmonary artery angioplasty[1], left femoro-bilateral axillary bypass[1] and others[2]. There was no hospital death.Mean duration of follow-up was 42.7 months[ranged from 3 to 96 months].There was one late death and late mortality rate is 5.9%.Two patients was underwent second vascular procedures, one after 5 years and the other after 5 months.The other patients have done well after surgery.
