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.

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.

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.

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.

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.

BACKGROUND: The interest in robotic cardiac surgery has recently grown but there has not been much clinical research reported on this. The aim of this study is to examine our initial experience, since August 2007, with robotic cardiac surgery using the da Vince(TM) surgical system and to evaluate the feasibility and safety of it. MATERIAL AND METHOD: Between August and December 2007, a total of 20 patients underwent robotic cardiac surgery using the da Vinci surgical system. For mitral valve repair (n=11), tricuspid valve repair (n=1), and ASD repair (n=1), cannulation, antegrade cardioplegia and transthoracic aortic cross-clamping were conducted for the right femoral vessels and the right internal jugular vein. For minimally invasive direct CABG (MIDCAB) (n=7), the internal thoracic artery (ITA) was harvested with the da Vinci surgical system. RESULT: The mean age of the patients was 50.1 (range: 26~78) years. Three concomitant Maze procedures and one tricuspid annuloplasty were combined with mitral valve repair. The mean cardiopulmonary bypass time was 208.0+/-61.3 minutes and the aortic cross clamp time was 158.8+/-40.6 minutes. No patients showed more than mild mitral regurgitation after repair and the median hospital stay was 4 days. The robotic-harvested ITA was used for either left ITA (n=6) or bilateral ITA (n=1). The mean harvest time was 43.2+/-12.0 minutes. The harvested ITA showed good flow and it was anastomosed under direct vision after left anterolateral thoracotomy. The patency of all the grafts was 100% (18/18) in MIDCAB. CONCLUSION: Robotic cardiac surgery using the da Vinci surgical system was variously adapted to areas such as mitral and tricuspid valve repair, ASD repair and ITA harvest for MIDCAB. The early results of the robotic cardiac surgery showed its safety and feasibility. With this primary report, we anticipate that clinical applications and further studies on robotic cardiac surgery using the da Vinci surgical system will be actively conducted in Korea.

PURPOSE: The Maze procedure has shown excellent efficacy in the elimination of atrial fibrillation (AF); however, little is known about the quality of functional recovery in the left atrium (LA) following successful sinus rhythm conversion by the Maze procedure. MATERIALS AND METHODS: We prospectively enrolled 12 patients (aged 52.5+/-10.1 years, 1 female) with valvular AF undergoing mitral valve surgery combined with the Maze procedure. Parameters of LA function in three anatomic compartments [anterior, posterior, and LA appendage (LAA)] were evaluated using electrocardiography-gated dual-source cardiac CT at one month and at six months after surgery. Twelve subjects matched by age, gender, and body surface area served as controls. RESULTS: At one month after surgery, ejection fraction (EF) and emptying volume (EV) of the LA were 14.9+/-7.4% and 21.3+/-9.7 mL, respectively, and they were significantly lower than those of the control group (EF, 47.9+/-11.2%; EV, 46.0+/-10.7%; p<0001). These values did not significantly change throughout late periods (p=0.22 and 0.21, respectively). Functional contributions of the anterior, posterior, and appendage compartments (EV of each compartment/overall EV) were 80.4%, -0.9%, and 20.5%, respectively, for those with LAA preservation (n=6); 100.1%, -0.1%, and 0% for those with LAA resection (n=6; p<0.05); and 62.2%, 28.2%, and 9.7% in the control subjects (p<0.001). CONCLUSION: Contractile functions of the LA significantly decreased after the Maze procedure. Functional contributions of three compartments of the LA were also altered. The influence of LAA preservation on postoperative LA functions needs to be evaluated through studies of larger populations.
