A 70-year old male with dilated cardiomyopathy was admitted to our hospital because of a renal stone, and a supra-renal abdominal aortic aneurysm was detected during work-up. We performed a hybrid surgery using an endovascular stent because of his co-morbidities. The operation consisted of removal of the renal stone, de-branching of the visceral artery and both renal arteries from the abdominal aorta, reperfusion of the de-branched arteries with retrograde bypass surgery using two Y-graft from the left external iliac artery, and deployment of stent graft in the abdominal aorta. Therefore, we report a case of hybrid surgery for supra-renal abdominal aortic aneurysm.

Although surgical closure is the standard approach for a muscular ventricular septal defect, the procedure may be complicated by poor visualization and the need for incision on the ventricle. Another approach is, catheter-based intervention. However, it also has limitations. A hybrid procedure, the intraoperative combined use of an interventional device may reduce the procedure's invasiveness. We successfully managed two cases of muscular ventricular septal defect with a hybrid procedure. We report here on these 2 cases along with a review of the literature.

Background: A hybrid procedure using an open surgical extra-anatomic bypass of aortic arch vessels and thoracic endovascular aortic repair (TEVAR) is less invasive than open surgery, and provides a suitable proximal landing zone. Here we report our experience with a hybrid TEVAR procedure at a single center. Material and Method: We retrospectively reviewed consecutive patients with thoracic aortic disease who received a hybrid TEVAR procedure between August 2008 and January 2010. Patients' data were prospectively collected and mean follow-up was $10.8{\pm}5.5$ months (range 3~20). Result: Nine patients (7 males and 2 females) with a mean age of $63.8{\pm}15.8$ years (range 38~84) underwent a hybrid procedure. Five patients had an arch or a proximal descending aortic aneurysm, two had a dissecting aneurysm of the descending aorta, and two had an aneurysm of the ascending arch and descending aorta. Mean expected mortality calculated by logistic EuroSCORE was 21%. Six patients underwent debranching and rerouting from ascending aorta to arch vessels, 2 had carotid-carotid bypass grafting, and 1 underwent carotid-axillary bypass grafting. Mean operation time was $221.4{\pm}84.0$ min (range 94~364). Deployment success of endovascular stent grafting was 100% with no endoleak on completion angiography. There was no mortality, and a small embolism in the branch of the right opthalmic artery in one patient. During follow-up, one intervention was required for the endoleak. Actuarial survival at 20 months was 100%. Conclusion: Early and mid-term results are encouraging and suggest that hybrid TEVAR procedures are less invasive and safer and represent an effective technique for treating thoracic aortic disease.

Hybrid procedure was performed for a thirteen-day-old girl with a functionally single ventricle, who weighed 2.2 kg and had been prematurely born at $32^{+5}$ weeks of gestation. She underwent bilateral pulmonary artery banding using 3.5 mm Gore-Tex graft, ductal stenting using balloon expandable stent, and reverse Blalock-Taussig shunt with 3.5 mm Gore-Tex vascular graft. After discharge, she was followed up for 4 months, and underwent 2nd stage operation(extensive arch reconstruction with Damus-Kaye-Stansel anastomosis, atrial septectomy, bilateral pulmonary artery angioplasty, bidirectional cavopulmonary shunt). She has been followed up for 4 months after the 2nd operation with an excellent clinical condition.

A 53-year-old woman had right aortic arch, Kommerell’s diverticulum and aberrant left subclavian artery (LSA) without any compressive symptoms. Hybrid operation was performed. This consisted of LSA bypass using a 6 mm ringed Gore-Tex graft between the left common carotid artery and aberrant LSA via a left supraclavicular incision, and stent graft insertion into the aortic arch via the right femoral artery. Postoperative computed tomography as well as intraoperative angiography demonstrated successful occlusion of Kommerell’s diverticulum and bypass of the aberrant LSA. There were no complications related to the operation or the intervention.

Purpose: The Hybrid care environment, combining interventional procedures and surgeries in one space, is crucial for managing complex diseases, responding to emergencies, and reducing recovery times and pain. This study provides foundational data for creating architectural guidelines for a Hybrid Operating Unit in a general hospital's surgical department, focusing on cardiovascular care. Methods: The study analyzed the spatial and configuration types of the Vascular Angiography Unit and the Cardiac Operating Unit, which are the basic components of the Hybrid Operating Unit, through a literature review. Based on the initial research findings, interviews with experts were conducted. Results: In the Hybrid Operating Process, the study proposed spatial configuration alternatives that consider the positioning of medical staff and the types and arrangement changes of equipment, including Angiography, Heart-lung machines, and other surgical tools and instruments. Implications: The integration of the two units leads to increased diversity and demand for medical staff, equipment, and supplies during surgical and interventional procedures. Therefore, strategic spatial configurations and equipment placement are necessary to effectively respond to these needs.

Background: The possibility of incomplete revascularization and development of flow competition after revascularization of the borderline lesion made the hybrid strategy as an option for complete revascularization. Material and Method: From January f998 to July 2004, 25 $(3.2\%)$ patients underwent hybrid revascularization among 782 total OPCAB procedures. Clinical results and angiographic patencies were evalulated. Percutaneous coronary intervention (PCI) was peformed before CABG in 8 patients and after CABG in 47 patients. Result: The causes of PCIs before CABG were to achieve complete revascularization with minimally invasive surgery (n=7) and emergent PCI for culprit lesion (n=1). The indications of PCIs after CABG were high possibility of flow competition in the borderline lesion of right coronary artery territory (n=8), diffuse atheromatous lesion preventing anastomosis of graft (n=5), severe calcified ascending aorta with no more arterial grafi available (n=3), and intramyocardial coronary lesion (n=1). Mean number of distal anastomoses was $2.3\pm1.0$. Mean number of lesions treated by PCI was $1.2\pm0.4$. There was no operative or procedure-related mortality. PCI-related complication was periprocedural myocardial infarction in one patient, and complications related to CABG were transient atrial fibrillation (n=5), perioperative myocardial infarction (n=1), and transient renal dysfunction (n=1). Early postoperative coronary angiography $(1.8{pm}1.6days)$ revealed $100\%$ patency rate of grafts (57/57). The stenosis occurred in one patient performed PCI before CABG, which was successfully treated with re-ballooning. During midterm follow-up (mean; $25{\pm}26$ months), 1 patient died of congestive heart failure. All survivors (n=24) accomplished follow-up coronary angiographics, which showed .all grafts (56/57) were patent except one string sign. In-stent restenosis was developed in 2 patients who received bare metal stents. Conclusion: In selected patients, complete revascularization was achieved with low risk by taking the hybrid strategy.

Natural orifice transluminal endoscopic surgery is a newly emerging technique recently, with its many potential advantages in clinical practice. Cholecystectomy by Hybrid NOTES in this work, performed with single working channel endoscope in conjunction with a laparoscopic grasping forceps in dogs, is a "bridge" between laparoscopic procedure and pure NOTES. Three different approaches for cholecystectomy were carried out; transgastric, transcolonic and transvaginal. In all three approaches, abdominal opening was made by a 5 mm trocar, followed by making pneumoperitoneum of 4 mmHg with $CO_2$ insufflator. Transgastric cholecystectomy, single working channel endoscope was advanced to the peritoneal cavity through gastric incision in antral region made by endoscopic needle knife. Endoscope was retroflexed to visualize the gall bladder. Transcolonic access, incision for endoscopic entry was done at right ventral wall of descending colon, 15 cm inside from the anus. Incision in transvaginal access was made at right-ventral region, just caudal to the caudal tubercle. With the simple traction by the laparoscopic grasping forceps, good visualization of surgical field was obtained in all three groups. Cystic duct and artery were ligated with endoclips; for complete gall bladder dissection from liver, L-knife was used. Closure of incision sites were done in transgastric and transcolonic cholecystectomy by endoclips, not in transvaginal approach.

Surgical repair of thoracoabdominal aortic aneurysm (TAAA) remains a formidable challenge associated with significant rates of mortality and morbidity, especially in patients with high risk. Use of endovascular stent graff in aortic aneurysm disease is now accepted as an alternative treatment to surgery. But the saving of visceral arteries is the chief obstacle to endovascular repair of TAAA. We successfully treated two patients of TAAA with high risk by hybrid procedure including open visceral debranching and concomitant endovascular aneurysm exclusion.
