Pulmonary sequestration is an uncommon congenital pulmonary malformation characterized by presence of nonfunctioning lung tissue which receives its blood supply mostly from the anomalous systemic arteries - descending thoracic aorta or abdominal aorta, subclavian artery, innominated artery and internal mammary artery, etc. In our country, 39 cases were reported previously. The patient was a 40 years old woman and admitted due to productive cough for 1 year. The chest X-ray and chest C-T showed a dense mass containing a large cavity with air-fluid level and multiple radiolucent cysts in the right lower lung field. On the operative field, we could identify an aberrant large artery [ $\phi$7mm which arose directly from the descending thoracic aorta at eighth thoracic spinal level and fed the sequestrated portion of the right lower lobe. The aberrant artery was double ligation after division. Only sequestrated lobe on the superolateral lesion of the right lower lobe was resected because of nonseparated lobes in all the right lobes. An abnormal vein and bronchiole were ligated with black silk. The patient`s postoperative course was unevenful.

Isolated iliac artery aneurysm (IAA) is rare, but can be fatal. Emergency surgery is performed in cases of hemorrhagic shock due to a suddenly ruptured IAA, which may have a high mortality rate because of massive non-compressible torso hemorrhage (NCTH). Recently, resuscitative endovascular balloon occlusion of the aorta (REBOA) has been accepted as an alternative to aortic cross-clamping via open thoracotomy to achieve hemostasis in trauma patients with profound shock due to NCTH and is considered an emerging bridging therapy for damage control. However, there is limited information on the use of REBOA in non-trauma patients with shock. Herein, we describe a patient with impending cardiac arrest due to isolated ruptured IAA, in whom perioperative bleeding was successfully controlled by REBOA.

Background: Selective antegrade perfusion via axillary artery cannulation along with circulatory arrest under deep hypothermia has became a recent trend for performing surgery on the ascending aorta and aortic arch and when direct aortic cannulation is not feasible. The authors of this study tried using moderate hypothermia with right brachial and femoral artery perfusion to complement the pitfalls of single axillary artery cannulation and deep hypothermia. Materials and Methods: A retrospective analysis was performed on 36 patients who received ascending aorta or aortic arch replacement between July 2005 and May 2010. The adverse outcomes included operative mortality, permanent neurologic dysfunction and temporary neurologic dysfunction. Results: Of these 36 patients, 32 (88%) were treated as emergencies. The mean age of the patients was 61.9 years (ranging from 29 to 79 years) and there were 19 males and 17 females. The principal diagnoses for the operation were acute type A aortic dissection (31, 86%) and aneurysmal disease without aortic dissection (5, 14%). The performed operations were ascending aorta replacement (9, 25%), ascending aorta and hemiarch replacement (13, 36%), ascending aorta and total arch replacement (13, 36%) and total arch replacement only (1, 3%). The mean cardiopulmonary bypass time was $209.4{\pm}85.1$ minutes, and the circulatory arrest with selective antegrade perfusion time was $36.1{\pm}24.2$ minutes. The lowest core temperature was $24{\pm}2.1^{\circ}C$. There were five deaths within 30 post-op days (mortality: 13.8%). Two patients (5.5%) had minor neurologic dysfunction and six patients, including three patients who had preoperative cerebral infarction or unconsciousness, had major neurologic dysfunction (16.6%). Conclusion: When direct aortic cannulation is not feasible for ascending aorta and aortic arch replacement, the right brachial and femoral artery can be used as arterial perfusion routes with the patient under moderate hypothermia. This technique resulted in acceptable outcomes.

Aggressive revascularization of the ischemic lower extremities in atherosclerotic, occlusive diseases or acute embolic arterial occlusion due to cardiac valvular disease by thromboembolectomy or an arterial bypass operation has been advocated by some authors. We have performed 68 first time vascular operations, including thromboembolectomies on RR patients with ischemic lower extremities, within an 11-year-and-6-month period, from January 1974 to June 1984. We have reviewed and analyzed our vascular operative procedures and post operative results. The patients upon whom thromboembolectomies were performed were 42 males and 13 females ranging from 5 to 72 years of age. The major arterial occlusive sites were common iliac artery in 20 cases, femoral artery in 21 cases, popliteal artery in 8 cases, common iliac artery and femoral artery in 4 cases, and femoral artery and popliteal artery in 3 cases. The underlying causes of arterial occlusive disease were atherosclerosis obliterans in 34 cases; Buerger`s disease in 3 cases; emboli due to cardiac valvular disease in 13 cases; and vascular trauma in 4 cases, including cardiac catheterization in I of those cases. Arterial bypass operations with autogenous or artificial vascular prosthesis were done in 31 cases. Amputations were done on 2 patients carrying out any more vascular operative procedures would have been of no benefit to them. Our bypass operations for ischemic lower extremities were classified as follows: those done between the abdominal aorta and the femoral artery in 17 cases, including those done between the aorta and the bifemoral arteries with a Y graft in four of those cases and long ones done from the axillary to the femoral artery in 4 cases. Five patients died in the hospital following vascular surgery for ischemic lower extremities, the causes of death were not directly related to the vascular reconstructive operative procedures. The leading causes of death were respiratory failure due to metastatic lung carcinoma: renal failure due to complications from atherosclerosis obliterans; sepsis from open, contaminated fractures of the tibia and fibula; and myocardial failures due to open heart surgery in one case and reconstructive surgery of the ascending aorta in another.

Mini-pigs have been widely employed in preclinical studies to explore new therapeutic strategies for diseases of the human urinary system; however, the normal reference of the renal artery has not been clearly investigated in the mini-pig model. Therefore, we aimed to establish a normal reference of the radiological morphology of the renal artery in mini-pigs by renal angiography via catheterization of the carotid artery. The renal angiographies obtained from 15 mini-pigs were evaluated to determine the orifice from the aorta, facing direction, size and the number of branches of renal arteries. Cranio-laterally facing renal arteries with 2 distal branches were mainly observed in the renal artery of mini-pigs. Both sides of the renal artery presented symmetrical sizes; however, the right renal artery orifice from the aorta was located more cranially than the left counterpart. The results of this study will contribute to radiological diagnosis of the renal artery as well as preclinical studies of mini-pigs.

Takayasu`s arteritis is one of chronic inflammatory disease characteristically involving the aorta and its major branches. Symptoms and signs of the disease are various depending on the involved area. We experienced a surgical case of Takayasu`s arteritis mainly involving both renal arteries with renovascular hypertension in a 13 year old girl. Hypertension was not controlled by medical treatment including diuretics and captopril [160/140 mmHg]. Aortogram showed severely stenosed right renal artery, nearly obstructed left renal artery and not visulalized superior mesenteric artery. Angioplasty was performed for the right renal artery but aorta-renal bypass graft with greater saphenous vein was inevitable for the left renal artery. Blood pressure was controlled sufficiently with some adjunct of captopril postoperatively [130/90 mmHg]. While the patient was discharged with much improvement, she was lost follow up and died of not identified definitive cause 3 months later.

The left aortic arch with an aberrant right subclavian artery, or arteria lusoria, is the most common aortic arch anomaly, occurring in 0.5-2.5% of individuals. In such cases, the angular course of the arteria lusoria to the ascending aorta imposes difficulty in passing a guide wire to the ascending aorta during right transradial catheterization. Here, the case of a 53-year-old woman with intermittent chest tightness and coughing is reported. Aberrant right subclavian artery (arteria lusoria) was diagnosed via aortogram during right transradial coronary angiography. Compression of the esophagus and trachea by the aberrant right subclavian artery was demonstrated by chest computed tomography (CT).

Objectives : We have examined the relaxational response to the water extract of genus Panax in rat thoracic aorta and mesenteric artery. 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 genus Panax with a dose-dependent vasorelaxation. At $10^{-5}m$ 5-hydroxytrptamine (5-HT), the maximal contraction force were 94.9% of the maximum KCl-response. At $10^{-5}m$ 5-HT - induced contraction, The contractile response of thoracic aortic rings were inhibited by 54.7%, 36.3% and 31.3% after addition of the high concentration (100 mg/ml) of water extract of Panax ginseng, Panax japonicus and Panax quinquefolium. The contractile response of mesenteric arteries were inhibited by 88.3%, 87.7%, and 70.3% after addition of the high concentration (100 mg/ml) of water extract of Panax ginseng, Panax japonicus and Panax quinquefolium. Conclusions : In conclusion, water extract of genus Panax - induced relaxation in the isolated rat thoracic aorta and mesenteric artery were composed of endothelium - independent relaxation and dose - dependent relaxation.

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.

A 49-year-old male presented with chills and a fever. Five years previously, he underwent ascending aorta and aortic arch replacement using the elephant trunk technique for DeBakey type 1 aortic dissection. The preoperative evaluation found an esophago-paraprosthetic fistula between the prosthetic graft and the esophagus. Multiple-stage surgery was performed with appropriate antibiotic and antifungal management. First, we performed esophageal exclusion and drainage of the perigraft abscess. Second, we removed the previous graft, debrided the abscess, and performed an in situ re-replacement of the ascending aorta, aortic arch, and proximal descending thoracic aorta, with separate replacement of the innominate artery, left common carotid artery, and extra-anatomical bypass of the left subclavian artery. Finally, staged esophageal reconstruction was performed via transthoracic anastomosis. The patient's postoperative course was unremarkable and the patient has done well without dietary problems or recurrent infections over one and a half years of follow-up.
