  • Ten patients underwent operation for aortic aneurysms from Jan. 1983 to April 1988 at the Department of Thoracic and Cardiovascular Surgery, Keimyung University Hospital. There were 7 males and 3 females in this series. The age ranged from 16 to 70 years with the mean age of 45 years. The cause of the aneurysm was atherosclerosis in 8 patients, mycosis in 1 patient and unknown in 1 patient. There were two patients with ascending aortic aneurysm treated by Dacron graft replacement, with no hospital death. One patient with aortic arch aneurysm was received Dacron graft replacement under cardiopulmonary bypass and died on the 21st postoperative day because of cerebral edema. There were three patients with descending aortic aneurysm. The aneurysm in two patients was successfully repaired by Dacron graft. One additional patient with ruptured aneurysm died at operation because of ventricular fibrillation. Four patients with abdominal aortic aneurysm were underwent Dacron graft replacement and the results were good.

  • Aortic abdominal aneurysm rarely has been reported as causing osteolytic lesions of the spine. It may produce back and radiating pain patterns similar to those of several commonly encountered neurosurgical processes. We report a uncommon complication of huge pulsating aortic aneurysm causing severe vertebral erosion with incapacitating back and radiating pain.

  • For high-risk patients, endovascular aortic aneurysm repair (EVAR) is a good option but may lead to serious complications, which should be addressed immediately. A 75-year-old man with a history of abdominal surgery underwent EVAR for an aneurysm of the abdominal aorta and iliac arteries. During EVAR, iliac artery rupture and graft limb occlusion occurred, and they were successfully managed by the additional deployment of an iliac stent graft and balloon thrombectomy, respectively. We, herein, report a rare case of the simultaneous development of the two fatal complications treated by the endovascular technique.

  • 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.

  • This study was designed to determine the effects of the long non-coding RNA (lncRNA) plasmacytoma variant translocation 1 (PVT1) on vascular smooth muscle cell (VSMC) apoptosis and extracellular matrix (ECM) disruption in a murine abdominal aortic aneurysm (AAA) model. After injection of PVT1-silencing lentiviruses, AAA was induced in Apolipoprotein E-deficient ($ApoE^{-/-}$) male mice by angiotensin II (Ang II) infusion for four weeks. After Ang II infusion, mouse serum levels of pro-inflammatory cytokines were analysed, and aortic tissues were isolated for histological, RNA, and protein analysis. Our results also showed that PVT1 expression was significantly upregulated in abdominal aortic tissues from AAA patients compared with that in controls. Additionally, Ang II treatment significantly increased PVT1 expression, both in cultured mouse VSMCs and in AAA murine abdominal aortic tissues. Of note, the effects of Ang II in facilitating cell apoptosis, increasing matrix metalloproteinase (MMP)-2 and MMP-9, reducing tissue inhibitor of MMP (TIMP)-1, and promoting switching from the contractile to synthetic phenotype in cultured VSMCs were enhanced by overexpression of PVT1 but attenuated by knockdown of PVT1. Furthermore, knockdown of PVT1 reversed Ang II-induced AAA-associated alterations in mice, as evidenced by attenuation of aortic diameter dilation, marked adventitial thickening, loss of elastin in the aorta, enhanced aortic cell apoptosis, elevated MMP-2 and MMP-9, reduced TIMP-1, and increased pro-inflammatory cytokines. In conclusion, our findings demonstrate that knockdown of lncRNA PVT1 suppresses VSMC apoptosis, ECM disruption, and serum pro-inflammatory cytokines in a murine Ang II-induced AAA model.

  • Eight patients received operation for ascending aortic aneurysm and aortic regurgitation associated with Marfan`s syndrome from January 1984 to July 1986 at Seoul National University Hospital. The patients` age ranged from 29 to 51 years [mean 37.3 years]. Five patients were male and three were female. All of them showed some stigmata of skeletal system in Marfan`s syndrome. Three patients had dissecting aneurysm and five patients had fusiform aneurysm of ascending aorta. Two patients had concomitant fusiform aneurysm of abdominal aorta. All patients showed aortic regurgitation of grade III to IV. One patient received insertion of intraluminal ringed graft and resuspension of aortic valve, and seven patients received modified Bentall operation [Carol`s method]. There was no hospital death and all showed functional improvement in the 7.4 patient-years follow-up period.

  • 저자들은 우리나라에서는 처음으로 복강경을 이용한 수기보조 방법으로 복부 대동맥류 치환술을 시행하였다. 환자는 67세 남자였으며, 복부 대동맥류의 직경은 약 5.8 cm였다. 첫 단계로 상복부에 6 cm 절개선을 내고, 복강경하에서 집도의의 왼손을 이용하여 대동맥류 주위를 박리하였다. 근위부 문합은 절개창을 통하여 직접 하였으며, 인조혈관의 양쪽 다리를 후복막을 통하여 양족 서혜부에서 총대퇴동맥과 단측문합하였다. 환자는 술 후 6시간 후 경구 식이를 시작하였으며, 술 후 4일째 퇴원하였다.

  • 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.

  • 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.
