Emergency surgical repair for acute traumatic aortic ruptures has been associated with a high peri-procedural mortality rate. Endovascular stent-grafting, as a less invasive procedure, has shown encouraging results. This report describes a patient with a short landing zone, who was treated by transposing the supra-aortic branch without sternotomy, followed by covered stent-grafting with an extended proximal bare portion to enhance fixation.

The authors report one case of akinetic mutism with obstructive hydrocephalus. The patient suffered from multiple shunt failures and shunt revision. After multiple shunt revision, the patient fell into an akinetic-mute state. She appeared awake but was no response to painful somatosensory, loud auditory or threatening visual stimuli and she required total nursing care. This behavioral syndrome was no response to shunt revision but we were able to successfully treat a case of akinetic mutism after combination theraphy of Bromocryptine and Ephedrine.

A 23 years old single nulligravida woman underwent laparoscopic removal of a huge cystic adnexal mass that occupied her entire abdomen, giving the appearance of a full term pregnancy. After anesthesia, a vertical infra-umbilical incision, 1 cm long, was made and a telescope was introduced through the port to determine the status of the intra-abdomen and the surface contour of the mass. A needle tipped with a laparoscopic suction apparatus was inserted into the cyst through the infra-umbilical port, directly under the mass. Subsequently, 3, 200 ml of cystic fluid was aspirated without spillage. A huge cyst, reaching to the level of the xyphoid process was effectively excised through the operative laparoscopy after prelaparoscopic drainage. Operation time was 140 minutes and hospital stay was 2 days. There were no complications during hospital stay and after discharge. It seems the size of the cyst is not a criteria for the contraindication of laparoscopic surgery.

Selection of a treatment modality for traumatized renal rupture depends on the renal injury grade, hemodynamic stability, combined organ injury, and the physician's experience. Treatment for renal injury tends to be conservative to maintain renal function and lessen the morbidity of surgery. If renal injuries were well-staged and selected by radiologic evaluation, hemodynamically stable patients with significant injuries (grades II through V) can usually be managed without surgical exploration. We report 3 cases of grade 4 renal injuries successfully treated with selective renal arterial embolization.

OBJECTIVE: This study aimed to assess the surgical morbidity and mortality of thoracic endovascular repair (TEVAR) as compared with open surgical repair (OSR) for isolated descending thoracic aortic disease. MATERIALS AND METHODS: From January 1, 2006 through May 31, 2010, a total of 68 patients with isolated descending thoracic aortic disease were retrospectively reviewed for the presence of perioperative complication, 30-day mortality, and clinical success. The patients were divided into two groups (group 1, OSR, n = 40 vs. group 2, TEVAR, n = 28) and these groups were compared for major variables and late outcomes. RESULTS: The mean age was 58 years (group I = 54 vs. group II = 63 years, p = 0.011). Significant perioperative complications occurred in 12 patients: 8 (20%) in group I and 4 (13%) in group II (p = 0.3). There were five 30 day mortalities of which 4 occurred in group I and 1 in group II (p = 0.23). Clinical success (effective aortic remodeling and complete false lumen obliteration or thrombosis) was achieved in 20 patients (71%). Mean Kaplan-Meier survival rate at 1 year was similar for both groups (group 1 = 87% vs. group 2 = 80%, p = 0.65). CONCLUSION: Thoracic endovascular repair for isolated thoracic aortic disease shows comparable results to OSR. However, the potential for endoleak or rupture remains a challenge that needs to be addressed in the future. Therefore, close follow-up study is needed for the evaluation of satisfactory long-term outcomes.

BACKGROUND: The choice between a bioprosthetic and a mechanical valve is an important decision in cardiac valve surgery, and the durability of the tissue valve is a major decision factor. We retrospectively evaluated the midterm results of bioprosthetic valve replacement in the mitral position. MATERIAL AND METHOD: The subjects were all patients who had undergone mitral bioprosthesis replacement between July 1989 and August 2007. Among the 216 patients, there were 236 surgical cases. The mean age was 63+/-15 years, and the male to female ratio was 1:3. We retrospectively analyzed hospital and outpatient records such that the total follow-up duration amounted to 760.2 patient-years, and the mean follow-up duration was 41.9+/-40.7 months (range 0~212 months). RESULT: Early death occurred in 18 patients (8.3%), and 13 of these underwent concomitant cardiac procedures. The survival rate after 5 years was 79.9+/-3.5%, and the survival rate after 8 years was 65.5+/-5.5%, while freedom from structural valve deterioration (SVD) was 96.2+/-2.2% at 5 years and 85.9+/-5.3% at 8 years. Freedom from reoperation was 96.0+/-1.7% at 5 years and 90.4+/-4.2% at 8 years, while freedom from reoperation for SVD was 98.1+/-1.2% at 5 years and 92.3+/-4.1% at 8 years. On multivariate analysis of preoperative risk factors, small valve size (between 25 mm and 27 mm) was a significant risk factor for reoperation, and low LV ejection fraction (<40%) was a significant risk factor for SVD and mortality. CONCLUSION: Survival and freedom from reoperation for SVD in mitral bioprosthesis replacement had acceptable midterm results, but freedom from SVD was relatively low. In particular, since SVD increased sharply at the eighth postoperative year, frequent follow-up and echocardiograms around that time will be helpful for the early detection of SVD. It will be necessary to conduct further studies involving long-term follow-up and more patients.

Minimally invasive cardiac surgery using AESOP (Automated Endoscope System for Optimal Positioning) offers certain advantages such as better a cosmetic outcome, a shortened post operative recovery time and a shorten hospital stay, and these advantages are not achieved by conventional cardiac surgery. We report here on our first robot-assisted (AESOP) left minithoracotomy surgery in a 26 year-old female with a subarteral ventricular septal defect, and this might have been treated by median sternotomy before the development of AESOP.

BACKGROUND: We reviewed the long-term outcomes of aortic root replacement at Asan Medical Center and investigated the predictors affecting mortality. MATERIALS AND METHODS: A retrospective analysis was performed on 225 consecutive adult patients undergoing aortic root replacement with mechanical conduits (n=169), porcine aortic root prosthesis (n=23), or aortic homografts (n=33) from January 1992 to September 2009. The median follow-up duration was 6.1 years (range, 0 to 18.0 years). RESULTS: The porcine root group was older than the other groups (freestyle 55.9+/-14.3 years vs. mechanical 46.3+/-14.6 years, homograft 48.1+/-14.7 years; p=0.02). The mechanical group had the highest incidence of the Marfan syndrome (mechanical 22%, freestyle 4%, homograft 3%; p=0.01). Surgery performed for infective endocarditis was more frequent in the homograft group (mechanical 10%, freestyle 10%, homograft 40%; p<0.001). The overall 30-day mortality was 5.3% (12/225). Actuarial survival rates in the mechanical, porcine root, and homograft groups were 79.4%, 81.5%, and 83.5% at 5 years and 67%, 61.9%, and 61.1% at 10 years, respectively (p=0.73). By multivariate analysis, preoperative diabetes mellitus, older age, and longer cardiopulmonary bypass time were independent predictors of mortality. Incidence of postoperative complications, including infective endocarditis and thromboembolism were comparable in all of the groups. CONCLUSION: Aortic root replacement can be safely performed with different types of prostheses as the outcome was not affected by the choice of prosthesis. Further studies are required to assess the long-term durability of biological prostheses.

BACKGROUND: Although a residual intimal tear may contribute to the dilatation of the descending aorta following surgical repair of acute type I aortic dissection (AD), its causal relationship has not been elucidated by clinical data due to the limited resolution of imaging modalities. METHODS: This study enrolled 41 patients (age, 55.2+/-11.9 years) who were evaluated with dual-source computed tomography (CT) imaging of the whole aorta in the setting of the surgical repair of acute type I AD. Logistic regression models were used to determine the predictors of a composite of the aortic aneurysm formation (diameter >55 mm) and rapid aortic expansion (>5 mm/yr). RESULTS: On initial CT, a distal re-entry tear was identified in 9 patients. Two patients failed to achieve proximal tear exclusion by the surgery. Serial follow-up CT evaluations (median, 24.6 months; range, 6.0 to 67.2 months) revealed that 14 patients showed rapid expansion of the descending aorta or aortic aneurysm formation. A multivariate analysis revealed that the residual intimal tear (odds ratio [OR], 4.31; 95% confidence interval [CI], 1.02 to 19.31) and the patent false lumen in the early postoperative setting (OR, 4.64; 95% CI, 0.99 to 43.61) were predictive of the composite endpoint. CONCLUSION: The presence of a residual intimal tear following surgery for acute type I AD adversely influenced the expansion of the descending aorta.
