Surgical Significance of the Aortic Root and its Neighbouring Structure Relationships

Objective: To measure the calibration of different levels in aortic root andevaluate the relationships between the aortic sinuses and its neighbouring structure. Methods:Thirty heart specimens from cadaver of normal adult were studied. The dimensions of four levels inaortic root were measured and the relationships between the aortic sinues and its neighbouringstructure were observed. Results: The dimensions of four levels in aortic root obtained as follows;Sinus > STJ1 > STJ0 > Base (P < 0.05) . The dimensions of the aortic valve leaflets were measured.The right coronary leaflet was larger than those of the left coronary and noncor-onary leaflets .But there was no statistical signiftcane (P > 0.05) . The relationships between the middle axis ofthe anterior valve of the bicuspid valve and the aortic sinuses were examined. The middle axis ofthe anterior valve in 26 specimens (86.6%) located between the left coronary sinus and thenoncoronary sinus . The relationship between the aortic prominence of the right atrium and theaortic sinuses was examined. The aortic prominence was formed from noncoronary sinus in 22 specimens(73.3%) . The relationship between the middle point of the right and left pulmonary valves and theaortic sinuses was examined. The middle point of the right and left pulmonary valves in 24 specimens(80%) was faced to the point between the right and left aortic sinuses . Conclusion: The dimensionof the four levels in aortic root is as follows, sinus > STJ1 > STJ0 > Base (P < 0.05) . There wasno statistical significance in the size of the three aortic valve leaflets (P > 0.05).

Surgical resection of a solitary para-aortic lymph node metastasis from hepatocellular carcinoma

Lymph node (LN) metastases from hepatocellular carcinoma (HCC) are considered uncommon. We describe the surgical resection of a solitary para-aortic LN metastasis from HCC. A 65-year-old Japanese man with B-type liver cirrhosis was admitted for the evaluation of a liver tumor. He had already undergone radiofrequency ablation, transcatheter arterial chemoembolization, and percutaneous ethanol injection therapy for HCC. Despite treatment, viable regions remained in segments 4 and 8. We performed a right paramedian sectionectomy with partial resection of the left paramedian section of the liver. Six months later, serum concentrations of alpha-fetoprotein (189 ng/mL) and PIVKA-2 (507 mAU/mL) increased. Enhanced com- puted tomography of the abdomen revealed a tumor (20 mm in diameter) on the right side of the abdominal aorta. Fluorine-18 fluorodeoxyglucose positron emission tomography revealed an increased standard uptake value. There was no evidence of recurrence in other regions. Esophagogastroduodenoscopy and colonoscopy revealed no malignant tumor in the gastrointestinal tract. Para-aortic LN metastasis from HCC was thus diagnosed. We performed lymphadenectomy. Histopathological examination revealed that the tumor was largely necrotic, with poorly differentiated HCC on its surface, which confirmed the suspected diagnosis. After 6 mo tumor marker levels were normal, with no evidence of recurrence. Our experience suggests that a solitary para-aortic LN metastasis from HCC can be treated surgically.

A Case of Large “Silent” Extra-adrenal Retroperitoneal Paraganglioma Resected Laparoscopically

SILENT extra-adrenal retroperitoneal paragangliomas (PGLs) arise from dispersed paraganglias which tend to be symmetrically distributed in close relation to the aorta and sympatheticnervous system. They are rarely encountered in everyday surgical practice.

Prognostic value of the ratio between prosthesis area and indexed annulus area measured by MultiSlice-CT for transcatheter aortic valve implantation procedures

Background Postprocedural aortic regurgitations following transcatheter aortic valve implantation （TAVI） procedures remain an is- sue. Benefit of oversizing strategies to prevent them isn＇t well established. We compared different level of oversizing in our cohort of con- secutive patients to address if severe oversizing compared to normal sizing had an impact on post-procedural outcomes. Methods From January 2010 to August 2013, consecutive patients were referred for TAVI with preoperative Multislice-CT （MSCT） and the procedures were achieved using Edwards Sapien~ or Corevalve devices~. Retrospectively, according to pre-procedural MSCT and the valve size, pa- tients were classified into three groups： normal, moderate and severe oversizing; depending on the ratio between the prosthesis area and the annulus area indexed and measured on MSCT. Main endpoint was mid-term mortality and secondary endpoints were the Valve Academic Research Consortium （VARC-2） endpoints. Results Two hundred and sixty eight patients had a MSCT and underwent TAVI procedure, with mainly Corevalve~. While all-cause and cardiovascular mortality rates were similar in all groups, post-procedural new pacemaker （PM） implantation rate was significantly higher in the severe oversizing group （P = 0.03）, while we observed more in-hospital congestive heart-failure （P = 0.02） in the normal sizing group. There was a trend toward more moderate to severe aortic regurgitation （AR） in the normal sizing group （P = 0.07）. Conclusions Despite a higher rate of PM implantation, oversizing based on this ratio reduces aortic leak with lower rates of post-procedural complications and a similar mid-term survival.

Minimally invasive aortic valve surgery

Aortic valve disease is a prevalent disorder that affects approximately 2% of the general adult population. Surgical aortic valve replacement is the gold standard treatment for symptomatic patients. This treatment has demonstrably proven to be both safe and effective. Over the last few decades, in an attempt to reduce surgical trauma, different minimally invasive approaches for aortic valve replacement have been developed and are now being increasingly utilized. A narrative review of the literature was carried out to describe the surgical techniques for minimally invasive aortic valve surgery and report the results from different experienced centers. Minimally invasive aortic valve replace- ment is associated with low perioperative morbidity, mortality and a low conversion rate to full sternotomy. Long-term survival appears to be at least comparable to that reported for conventional full sternotomy. Minimally invasive aortic valve surgery, either with a partial upper stemotomy or a right anterior minithoracotomy provides early- and long-term benefits. Given these benefits, it may be considered the standard of care for isolated aortic valve disease.

Surgery for rare aneurysm associated with colorectal cancer

The occurrence of concomitant aortic aneurysm and colorectal cancer is a rare medical entity,and con-troversy surrounds its optimal treatment.We report a case of rectal cancer and concomitant aneurysm from the ascending aorta to the common iliac artery.As with DeBakey typeⅠaortic dissecting aneurysm,our patient was treated by rectal cancer resection,with preservation of the anus(Dixon operation)under controlled hypo-tension.Blood pressure was maintained at 80-90/50-60 mmHg and the pulse at 70-90 beats/min.The pathological examination of the surgical specimen showed a poorly differentiated T3N0 tumor.The patient had an uneventful recovery without aneurysm rupture,and was discharged from hospital on postoperative day 15 after 3 d adjuvant chemotherapy with oxaliplatin combined with calcium folinate and fluorouracil.The patient was given six courses of adjuvant chemotherapy in 6 mo,without recurrence or metastasis,and the aneurysm was still stable after 2 years follow-up.

Thoraco-abdominal Aorta Revascularization through a Retroperitoneal Approach

Objective To investigate the application of the retroperitoneal approach in aortic surgery. Methods We collected and analyzed data of 7 patients in Macao who presented with aortic diseases from 2007 to 2008 and were treated with aorta repair through retroperitoneal approach. Demographic features as well as intraoperative and postoperative data were analyzed. One case of thoracoabdominal aneurysm and 4 cases of abdominal aneurysm received artificial graft, among which hybrid iliac artery reconstruction with Zenith stent covering the ostium of the left subclavian artery was performed in 2 cases of infrarenal abdominal aneurysm. Aortic-iliac artery bypass was performed in 2 cases of aortoiliac occlusion. Results No operative or early postoperative death was observed. No perioperative intestinal adhesion or ureteral obstruction was found. One case reported delayed paraplegia and graft infection as postoperative complications. The complications were partially removed 3 months later after rehabilitation. Conclusion Retroperitoneal approach is a safe and feasible technique, which associated with a low incidence of postoperative pulmonary complications.

Advanced age and the clinical outcomes of transcatheter aortic valve implan-tation

Aortic valve stenosis （AS） is common in the elderly. Although surgical replacement of the valve has been the gold standard of management, many patients have been excluded from surgery because they were very old, frail, or had co-morbidities that increased operative risks. In the last decade, transcatheter aortic valve implantation （TAVI） has emerged as a new treatment option suitable for these patients. This article reviews the available literature on the role of TAVI in elderly patients with severe aortic stenosis. Published studies showed that elderly individuals who underwent TAVI experienced better in-hospital recovery, and similar short and mid-term mortality compared to those underwent surgical treatment of AS. However, long-term outcomes of TAVI in elderly patients are still unknown. The available data in the literature on the ef-fect of advanced age on clinical outcomes of TAVI are limited, but the data that are available suggest that TAVI is a beneficial and tolerable procedure in very old patients. Some of the expected complications after TAVI are reported more in the oldest patients such as vascular in-jures. Other complications were comparable in TAVI patients regardless of their age group. However, very old patients may need closer monitoring to avoid further morbidities and mortality.

Aortic valve replacement with sutureless and rapid deployment aortic valve prostheses

Aortic valve stenosis is the most common valve disease in the western world. Over the past few years the number of aortic valve replacement （AVR） interventions has increased with outcomes that have been improved despite increasing age of patients and increasing bur- den of comorbidities. However, despite such excellent results and its well-established position, conventional AVR has undergone great de- velopment over the previous two decades. Such progress, by way of less irtvasive incisions and use of new technologies, including tran- scatheter aortic valve implantation and sutureless valve prostheses, is intended to reduce the traumatic impact of the surgical procedure, thus fulfilling lower risk patients＇ expectations on the one hand, and extending the operability toward increasingly high-risk patients on the other. Sutureless and rapid deployment aortic valves are biological, pericardial prostheses that anchor within the aortic annulus with no more than three sutures. The sutureless prostheses, by avoiding the passage and the tying of the sutures, significantly reduce operative times and may improve outcomes. However, there is still a paucity of robust, evidence-based data on the role and performance of sutureless AVR. Therefore, strongest long-term data, randomized studies and registry data are required to adequately assess the durability and long-term outcomes of sutureless aortic valve replacement.

Primary biliary cirrhosis after aortoiliac reconstruction surgery using a Y-graft: A case report

Primary biliary cirrhosis (PBC) is an autoimmune disease characterized by anti-mitochondrial antibodies and destruction of intra-hepatic bile ducts. Though little is known about the etiology of PBC, some reports suggest that xenobiotics and viral infections may induce PBC. We describe a case of PBC after the aortoiliac reconstruction surgery using a Y-graft.

Noninfectious Fever Following Aortic Surgery:Incidence,Risk Factors,and Outcomes

Objective To determine the incidence, course, potential risk factors, and outcomes of noninfectious fever developed in patients after aortic surgery. Methods Patients who received operation for aortic aneurysm or dissection in our center from January 2006 to January 2008 were reviewed. Patients who met one of the following criteria were excluded： having a known source of infection during hospitalization; having a preoperative oral temperature greater than or equal to 38.0℃; undertaking emergency surgery; having incomplete data. Univariate analysis was performed in patients with noninfectious postoperative fever and those without, with respect to demographics, intraoperative data, etc. Risk factors for postoperative fever were considered for the muhivariate logistic regression model if they had a P value less than 0.10 in the univariate analysis. Results Totally 463 patients undergoing aortic surgery were enrolled for full review. Among them, 345 （74.5%） patients had noninfectious postoperative fever, the other 118 （25.5%） patients didn＇t develop postoperative fever. Univariate analysis demonstrated that several risk factors were associated with the development of noninfectious postoperative fever, including weight, surgical procedure, minimum intraoperative bladder temperature, temperature upon intensive care unit （ICU） admission, discharge, and during ICU stay, as well as blood transfusion. In a further multivariate analysis, surgical site of thoracic and thoracoabdominal aorta （odds ratio： 4.861; 95% confidence interval： 3.029-5.801; P=0.004）, lower minimum intraoperative bladder temperature （odds ratio： 1.117; 95% confidence interval： 1.01-1.24; P=0.04）, and higher temperature on admission to the ICU （odds ratio： 2.57; 95% confidence interval： 1.28-5.18; P=0.008） were found to be significant predictors for noninfectious postoperative fever. No difference was found between the febrile and afebrile patients with regard to postoperative hospitalization duration （P=0.558） or total medical costs （P=0.896）. Conclusion Noninfectious postoperative fever following aortic surgery is very common and closely related with perioperative interventions.

Development of a Haptic Interface with Proximity Sensors and Vibration Motors

As described in this paper, we propose a new haptic interface for a service robot. For safety with service robots working in a space where people live, some notification before collision with an obstacle is desirable. To achieve such a function, we developed a master-slave manipulator system in which the slave manipulator surface is covered with many proximity sensors. Additionally, we developed a haptic device that feeds back proximity sense information to the operator using small vibration motors. We attached the haptic device to the arm of the operator and vibrated the vibration motor corresponding to the sensor. Thereby, the operator was able to ascertain the position of an object near the manipulator, and to make the robot maneuver to avoid it before collision. To confirm the system usefulness, we equipped subjects with the developed proximity sense presentation device and performed a detection-position-specific experiment and an obstacle avoidance experiment in a narrow space. As results of the detection position specific experiment on five subjects, four subjects reported the detection position correctly. The remaining one person failed because of his particular arm shape. Operation experiments conducted in a narrow space showed that all subjects＇ work was successful when given feedback of proximity sense information. Nobody was successful without proximity sense information. Results of these two experiments demonstrate that this proposed system is useful for obstacle avoidance of a master-slave manipulator system.

Aortic root replacement

Objective To report our operative experience with aortic root replacement in 231 patients with aortic root aneurysm and discuss the current indications, methods, and surgical techniques、Methods Between January 1994 and August 1999, a group of 231 consecutive patients underwent aortic root replacement at our hospital, with 13 being treated on an emergency basis、 There were 189 men and 42 women, ranging in age from 14 to 69 years、 The diameter of the aneurysm varied from 4、5 to 11?cm、 Among this group, 145 had isolated aortic root aneurysms, 65 suffered from DeBakey type Ⅰ aortic dissection, and the remaining 21 were diagnosed as having DeBakey type Ⅱ aortic dissection、 Aortic valve regurgitation occurred in all cases、 Aortic root replacement was performed with composite valved graft in 229 patients, and in 2 patients the aortic valve was preserved、Results The hospital mortality rate was 3、03% (7 patients)、 Early complications included re-exploration for bleeding in 6 patients, pericardial effusion in 9, as well as cerebral infarction, pleural effusion, and pneumothorax in 2 patients each、 One hundred and seventy-five patients (78、12%) were followed up, with a mean follow-up time of 15、7±13、1 months (range, 2 weeks to 65 months)、 One patient died from lower-limb embolism and renal dysfunction 3 months postoperatively、 Three patients died from postoperative anticoagulation accidents、 The preoperative and postoperative mean left ventricular end-diastolic diameters were significantly different (68、1±9、4?mm, range 54 to 112?mm; vs 54、8±8、2?mm, range 38 to 88?mm; P<0、001)、Conclusions Once a diagnosis of acute aortic root dissecting aneurysm is made, the patient should undergo surgery as soon as possible if the general conditions permit、 Aortic aneurysm without dissection or with chronic dissection should be operated if the diameter of the aneurysm is greater than 5?cm

Emergent treatment of patients with traumatic aorta ruptures

Objective ： To discuss our experience on the diagnosis and treatment of thoracic aorta rupture （TAR） that is one of the main common causes of death in the victims under blunt chest trauma. Methods： Between July 2001 and March 2006, 9 patients （6 men and 3 women, aged from 20 to 54 years ） suffering from acute traumatic aorta rupture after motor vehicle accidents received emergent surgical treatments in our hospital. Based on our experience in the rescue of the first TAR patient we introduced a practical procedure on the diagnosis and treatment of TAR in our department. All the other patients generally followed this procedure. Eight patients received contrast material enhanced helical computerized tomography scan before the operation. The leakage of coustrast medium from the aorta isthmus was found, and diagnosis of TAR was confirmed. Seven patients underwent immediate operation within 14 hours after accidents. One patient was treated on the 5th day of the accident because of delayed diagnosis of aortic rupture. All patients received general anesthesia with double lumen endotracheal tube and normothermic femoro-femoral partial cardiopulmonary bypass, with beating heart and aortic clamping. One patient received simple repair, and others received partial replacement of thoracic aorta with artificial vascular graft. Results： Seven TAR patients were successfully salvaged. Three patients combined brain injury as well as extremitiy hemiplegia before operation. After treatments one was fully and two partially recovered without paraplegia. Conclusions： Proper practical protocol is emphasized for the surgical repair of TAR because it will reduce the mortality of severe blunt chest injury.

Aorta-to-right atrium fistula,an unusual complication of endocarditis

Infective endocarditis(IE) remains a serious disease. Aorta-to-right atrium fistula is a rare but very serious complication of IE and predicts a higher mortality. This report describes a 50-year-old man with endocarditis,vegetation,perforation of noncoronary sinus,and formation of two aorta-to-right atrium fistulas with native valves detected by transthoracic echocardiography. This disease is lethal despite developments in cardiac imaging and antibacterial therapy. Early diagnosis,aggressive antibacterial therapy,and surgical treatment may improve the prognosis.
