RESUMO

Recently, the superior approach with transaction of the superior vena cava was introduced for the repair of supracardiac anomalies in adults. We developed a bidirectional right-angle venous cannula and placed it within the innominate vein to make the modified superior approach with the superior caval transection suitable for neonates and tiny infants. We applied this modified superior approach for the repair of infracardiac forms of total anomalous pulmonary venous drainage.

RESUMO

OBJECTIVE: We compared the outcomes of a new triple-branched stent graft reconstruction technique of total aortic arch with those of the conventional strategy of replacing the hemiarch during the surgical treatment of acute Debakey type I aortic dissection over five years. METHODS: Fifty-two patients with acute Debakey type I aortic dissection underwent ascending aorta replacement combined with triple-branched stent graft reconstruction of the aortic arch from June 2008 to February 2010. Concurrently, 41 cases of Debakey type I aortic dissection underwent ascending aorta replacement combined with hemiarch replacement. Both groups received hypothermic cardiopulmonary bypass and selective cerebral perfusion. RESULTS: Patient characteristics and in-hospital mortality of the two groups were similar. Postoperative data were not different between the groups. During the five years after surgery, there were no deaths in the stent graft group and three deaths in the hemiarch group. The late reinterventions/events during follow-up in the stent graft group were significantly less than those in the hemiarch group. On postoperative computed tomography, the aortic diameter of both groups was significantly reduced compared to the postoperative aortic diameter. There was no difference in diameter between one month and five years postoperatively in the stent graft group, although in the hemiarch group the diameter was significantly greater at five years than at one month postoperatively. CONCLUSION: The triple-branched stent graft reconstruction of the aortic arch is an effective and simplified procedure for the treatment of acute Debakey type I aortic dissection.

RESUMO

BACKGROUND: Acute type A aortic dissection (ATAAD) complicated by mesenteric malperfusion is a critical and complicated condition. The optimal treatment strategy remains controversial, debate exists as to whether aortic dissection or mesenteric malperfusion should be addressed first, and the exact time window for mesenteric ischemia intervention is still unclear. To solve this problem, we developed a new concept based on the pathophysiological mechanism of mesenteric ischemia, using a 6-hour time window to divide newly admitted patients by the time from onset to admission, applying different treatment protocols to improve the clinical outcomes of patients with ATAAD complicated by mesenteric malperfusion. METHODS: This was a retrospective study that covered a five-year period. From July 2018 to December 2020(phase I), all patients underwent emergency open surgery. From January 2021 to June 2023(phase II), patients with an onset within 6 h all underwent open surgical repair, followed by immediately postoperative examination if the malperfusion is suspected, while the restoration of mesenteric perfusion and visceral organ function was performed first, followed by open repair, in patients with an onset beyond 6 h. RESULTS: There were no significant differences in baseline and surgical data. In phase I, eleven patients with mesenteric malperfusion underwent open surgery, while in phase II, our novel strategy was applied, with sixteen patients with an onset greater than 6 h and eleven patients with an onset less than 6 h. During the waiting period, none died of aortic rupture, but four patients died of organ failure, twelve patients had organ function improvement and underwent surgery successfully survived. The overall mortality rate decreased with the use of this novel strategy (54.55% vs. 18.52%, p = 0.047). Furthermore, the surgical mortality rate between the two periods showed even stronger statistical significance (54.55% vs. 4.35%, p = 0.022). Moreover, the proportions of patients with sepsis and multiorgan failure also showed differences. CONCLUSIONS: Our novel strategy for patients with ATAAD complicated by mesenteric malperfusion not only improves the surgical success rate but also reduces the overall mortality rate.

RESUMO

BACKGROUND: In total arch replacement for patients with acute type A aortic dissection, anastomoses of the graft to the left subclavian artery and descending aorta are often difficult, and the arch vessel anastomosis is frequently performed at the site of dissection. To make this procedure easier and safer, we developed 2 modified techniques: open single-branched stent graft placement into the left subclavian artery and the descending aorta and reinforcement of the dissected arch vessel stump with a stent graft neointima. The feasibility and initial clinical results of these 2 new techniques are reported. METHODS AND RESULTS: Total arch repair with the 2 new techniques was performed in 26 patients with acute Stanford type A aortic dissection. Most patients had an uneventful postoperative course, and there were no surgical deaths. All implanted stent grafts were fully opened and not kinked, and there was no space or blood flow surrounding any of the stent grafts. The false lumen of the descending thoracic aorta closed with thrombus formation in 22 of 26 patients. Disappearance of the false lumen and recovery of the true lumen was observed in all of the dissected arch vessels. CONCLUSIONS: Open single-branched stent graft placement into the left subclavian artery and the descending aorta and reinforcement of the dissected arch vessel stump with a stent graft neointima are 2 simple and effective techniques that should make total arch repair an easier and safer procedure for acute type A aortic dissection.

RESUMO

Objectives: Most patients with acute aortic dissection (AAD) have a history of hypertension. Diagnosis of AAD in patients with hypertension at an early stage is complicated and challenging. This study aimed to explore the distinctive metabolic changes in plasma samples of AAD patients with hypertension and patients with hypertension only and provide early identification and diagnosis of AAD in patients with hypertension. Materials and methods: We collected blood samples from 20 patients with type A AAD and hypertension admitted to the emergency department and physically examined other 20 patients with hypertension as controls. The plasma metabolomic profiles of these patients were determined using untargeted metabolomics with ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry. Results: A total of 38 metabolites that differed between the AAD and hypertension groups were screened. In the positive ion mode, 12 metabolites were different between the two groups, and in the negative ion mode, 26 metabolites were different. Among the 26 different metabolites detected by the negative ion mode, 21 were significantly upregulated and five were downregulated in patients with AAD compared to patients with hypertension. Moreover, five metabolites were upregulated and seven were significantly downregulated in patients with AAD compared to those with hypertension, as detected by the positive ion mode. The metabolites differentially expressed in AAD were mainly involved in lipid metabolism (fatty acid biosynthesis, biosynthesis of unsaturated fatty acids, and linoleic acid metabolism), carbohydrate metabolism (galactose, fructose, and mannose metabolisms), and membrane transport (ATP-binding cassette transporters). Interestingly, plasma hydrocortisone and dimethylglycine concentrations were significantly increased in patients with type A AAD, with the highest area under the curve value (AUC = 0.9325 or 0.9200, respectively) tested by the receiver operating characteristic curve analysis. Conclusion: This study provides possible metabolic markers for the early clinical diagnosis of AAD in patients with hypertension.

RESUMO

BACKGROUND: Acute Stanford type A aortic dissection is often fatal, with a high mortality rate and requiring emergency intervention. Salvage surgery aims to keep the patient alive by addressing severe aortic regurgitation, tamponade, primary tear, and organ malperfusion and, if possible, prevent the late dissection-related complications in the proximal and downstream aorta. Unfortunately, no optimal standard treatment or technique to treat this disease exists. Total arch replacement with frozen elephant trunk technique plays an important role in treating acute type A aortic dissection. We aim to describe a modified elephant trunk technique and report its short-term outcomes. METHODS: From February 2018 to August 2019, 16 patients diagnosed with acute Stanford type A aortic dissection underwent surgery with the modified frozen elephant trunk technique at Xiamen Heart Center (male/female: 9/7; average age: 56.1 ± 7.6 years). All perioperative variables were recorded and analyzed. We measured the diameters of the ascending aorta, aortic arch, and descending aorta on the bifurcation of the pulmonary and abdominal aortas and compared the diameters at admission, before discharge, and 3 months after discharge. RESULTS: Fifteen patients (93.8%) had hypertension. The primary tears were located in the lesser curvature of the aortic arch and ascending aorta in 5 (31.3%) and 9 patients (56.3%), respectively, and no entry was found in 2 patients (12.5%). The dissection extended to the iliac artery and distal descending aorta in 14 (87.6%) and 2 patients (12.5%), respectively. The duration of cardiopulmonary bypass (CPB), cross-clamping, and antegrade cerebral perfusion were 215.8 ± 40.5, 140.8 ± 32.3, and 55.1 ± 15.2 min, respectively. Aortic valve repair was performed in 15 patients (93.8%). Bentall procedure was performed in one patient (6.3%). Another patient received coronary artery repair (6.3%). The diameters at all levels were greater on discharge than those on admission, except the aortic arch. After 3 months, the true lumen diameter distal to the frozen elephant trunk increased, indicating false lumen thrombosis and/or aortic remodeling. CONCLUSIONS: The modified frozen elephant trunk technique for acute Stanford type A aortic dissection is safe and feasible and could be used for organ malperfusion. Short-term outcomes are encouraging, but long-term outcomes require further investigation.

RESUMO

In the majority of patients presenting with acute type A aortic dissection (AAD) complicated by aortic valve insufficiency, the aortic valve (AV) can be preserved by AV resuspension. A meta-analysis was performed to investigate the outcomes following AV resuspension for AAD. A systematic literature search for publications reporting outcomes after AV resuspension in AAD published between January 1998 and June 2018 was conducted. Early outcome events and linearized occurrence rates for late outcome events were derived. The retrieval process yielded 18 unique studies involving 3295 patients with a total of 17 532 patient-years (pt-yrs). Pooled early mortality was 15.5% [95% confidence interval (95% CI) 11.5-19.4%, I2 = 91.9%], and the linearized late mortality rate was 3.21%/pt-yrs (95% CI 2.49-3.77, I2 = 29%). The linearized occurrence rates for aortic root reintervention was 1.4%/pt-yrs (95% CI 0.88-1.79, I2 = 48%); for recurrent significant aortic valve insufficiency (>2+), it was 1.12%/pt-yrs (95% CI 0.79-1.45, I2 = 68%); and for endocarditis, it was 0.01%/pt-yrs (95% CI 0-0.04, I2 = 7%). The composite rate of thromboembolism and bleeding was 1.41%/pt-yrs (95% CI 0.18-2.63, I2 = 82%). A more recent surgical period was associated with a decreased hazard of reoperation on the aortic root (P < 0.001). Requirement of AV resuspension alone in AAD is a risk factor for mortality. The long-term durability of AV resuspension is excellent, with low rates of endocarditis and thromboembolism and bleeding. Root reoperation hazard has become acceptable in recent years. Preoperative aortic valve insufficiency grade exceeding 2+ is a predictor for root reoperation.

RESUMO

OBJECTIVE: To Summarize the clinical experience of individual immunosuppressive regime in heart transplantation with high risk. METHODS: From September 2001 to December 2006, 51 cases with the complication of Hepatitis B viruses (HBV) infection, diabetes mellitus, renal dysfunction or pulmonary infection in perioperative period were analyzed retrospectively. All cases received daclizumab (Zenapax) induction therapy, and baseline triple immunosuppressive regime was consist of cyclosporine (CsA), azathioprine (Aza) or mycophenolate mofetil (MMF) and prednisone (Pred). Ten cases received HBV infection in preoperative period, the immunosuppressive protocol was emphasized on the use of MMF and the withdraw of Pred one month later in postoperation. Nine cases received diabetes mellitus in pre-operation, 4 cases had post-transplant diabetes mellitus. The immunosuppressive protocol was emphasized on the use of CsA rather than FK506, the use of Pred was less dosage, and the therapy of insulin was necessary. Sixteen cases had renal dysfunction in pre-operation, the use of MMF was routine but the use of CsA was delayed to the time 5 to 19 d postoperative. Twelve cases received pulmonary infection after allograft transplantation. The immunosuppressive agent was to be taped or suspended in therapy time. RESULTS: The liver function of the 10 cases with HBV infection was stable in 1 year follow-up, and 1 case received acute rejection after 13 months allograft transplantation. In the 6 months follow-up, the blood glucose level of the 13 cases with diabetes mellitus was stable, none of the cases suffered from acute rejection. In the one month follow-up, none of the 16 cases with renal dysfunction suffered from acute rejection, and the renal function was normal. Two of the 12 cases with the pulmonary infection were died of serious infection, others were survival. One case received acute rejection on the 17th day in postoperation. CONCLUSIONS: Low mortality can be realized by selecting appropriately individual immunosuppressive regime and the episode of acute rejection is rare.

RESUMO

We describe a modified volume reduction technique for a giant left atrium that consists of circumferential resection of a strip of left atrial wall with the appendage, plicated pericardium replacing the posterior atrial wall, and anastomoses of the remaining right side free wall to the interatrial septum instead of the interatrial groove. Our initial application showed that this technique can safely reduce a giant left atrium to the desired volume and obtain a high rate of sinus rhythm restoration after a maze operation.

RESUMO

In operations for acute type A aortic dissection with open technique in elderly patients and patients with long-term treatment of anticoagulation, the transverse pericardial sinus was routinely closed before the graft implantation. With the aid of both a bovine pericardial patch covering the pericardial recess between the superior caval vein and the pulmonary artery and an opening in the left inner side of the superior caval vein, this prophylactic transverse pericardial sinus closure could make autotransfusion of blood loss into the central venous system possible to deal with the diffuse oozing from the suture line.

RESUMO

Standard aortic valve replacement for aortic regurgitation caused by Behçet's disease is frequently complicated by postoperative recurrent prosthetic valve detachment. To prevent this, we have developed a modified Bentall procedure, in which the valved conduit is proximally attached to the left ventricular outflow tract instead of to the fragile annulus, based on the fact that the left ventricular outflow tract myocardium is rarely involved in Behçet's disease. This modified Bentall procedure was performed in 5 Behçet's disease patients with prosthetic valve detachment after primary aortic valve replacement, and satisfactory results were achieved.

RESUMO

BACKGROUND: To reduce some problems of traditional graft, we devise a modified multiple branched graft for repair of Crawford extent II and III thoracoabdominal aortic aneurysm (TAAA). CASE PRESENTATION: We described a modified multiple branched graft for Crawford extent II and III thoracoabdominal aortic aneurysm (TAAA) repair in 8 patients, Which comprised a main graft and three branches, and the third branch was bifurcated into two limbs. CONCLUSIONS: Our initial experience demonstrated that this modified multiple branched graft may make the thoracoabdominal aortic aneurysm(TAAA) repair easier and safer.

RESUMO

BACKGROUND: To simplify extensive repair of acute DeBakey type I aortic dissection, ascending aorta and hemiarch replacement combined with modified triple-branched stent graft implantation was developed. The descriptions and early results of this technique are reported. METHODS: From August 2014 to September 2015, 116 patients with acute DeBakey type I aortic dissection underwent ascending aorta and hemiarch replacement combined with modified triple-branched stent graft implantation. Clinical data of all patients were retrospectively reviewed. Survivors were followed up prospectively by computed tomography angiography. RESULTS: The cardiopulmonary bypass time was 131.5 ± 10.7 minutes, the aortic cross-clamp time was 50.0 ± 9.9 minutes, and the selective cerebral perfusion and lower body arrest time was 17.2 ± 2.2 minutes. The in-hospital mortality rate was 3.4%. Two patients were lost during follow-up. One patient died of a cerebrovascular accident 2 months after discharge, and another died of chronic renal failure 5 months after discharge. At the 3-month postoperative scans, complete thrombus formation of the false lumen around the implanted modified triple-branched stent graft occurred in all survivors, at the diaphragmatic level in 69.7% patients, and at the superior mesenteric arterial level in 8.3% patients. CONCLUSIONS: Extensive thoracic aorta repair of acute type I aortic dissection can be performed simply by combining ascending aorta and hemiarch replacement with modified triple-branched stent graft implantation. This technique can reduce the risk and technical difficulty of extensive thoracic aorta repair to levels close to those seen with ascending aorta and hemiarch graft replacement with open distal anastomosis.

RESUMO

OBJECTIVE: To study the postoperative hemodynamics after heart transplantation and treatment for disorders due to denervated transplanted hearts in order to improve the short term outcome of heart transplantation. METHODS: Forty one patients with endstage cardiopathy underwent orthotopic cardiac transplantation. The changes in the graft function were closely monitored during the postoperative period in order to maintain the stability of hemodynamics of the allografts. RESULTS: All recipients received vasoactive drug therapy and 6 recipients died of acute dysfunction of the right ventricle of the allograft during the postoperative period. The remaining patients survived well and led a life with rather good quality. CONCLUSION: The hemodynamic characteristics of a denervated grafted heart are unique. Close monitoring and good nursing care with rational administration of vasoactive drugs are the key measures for the prevention of acute dysfunction of the allograft in the early postoperative period.

RESUMO

OBJECTIVE: To report the preliminary experience of 21 orthotopic heart transplantations without early death. METHODS: Between April 2002 and June 2005, 21 patients underwent orthotopic heart transplantation. Recipients' pulmonary vascular resistance ranged from 3.0 to 5.9 wood units [mean (4.3 +/- 1.4) wood units]; Stanford myocardial protective solution or HTK solution was perfused for donor heart myocardial preservation, donor heart cold ischemic period ranged from 52 to 310 min [mean (81 +/- 23) min]; Three patients had previous cardiac operations under cardiopulmonary bypass, conventional Stanford orthotopic cardiac transplantation in 20 cases and total heart technique in 1 case; Recipients received simulect preoperatively and cyclosporine A, cellcept and prednisone postoperatively for prevention of acute allograft rejection; Patients received appropriate medical control of hypertension, hyperglycemia, hypercholesterolemia and uricacidemia. RESULTS: Acute right heart failure in 3 cases and pericardial effusion in 4 cases were observed at the early postoperative stage, but no any infection and acute rejection were found. All patients survived with good life quality. CONCLUSIONS: Heart transplantation may produce satisfying early results. Suitable selection of recipients with low pulmonary vascular resistance, excellent donor heart conservation, practised anastomotic technique, proper immunosuppression treatment and efficient postoperative management are key measures of orthotopic heart transplantation with excellent early outcome.

RESUMO

BACKGROUND: In the conventional ascending replacement for acute type A aortic dissection, the distal aortic anastomosis is frequently performed at the dissected site, and postoperative residual dissection in the arch and downstream aorta still occurs in most patients. We used open placement of a fenestrated stent graft during this operation. METHODS: During the conventional ascending replacement in 41 patients with acute type A aortic dissection, a fenestrated stent graft was inserted into the arch and the proximal descending aorta through the distal ascending transection. The distal ascending transection incorporating the proximal end of the fenestrated stent graft was directly anastomosed to the Dacron (DuPont, Wilmington, DE) tube graft. Survivors were examined by computed tomography angiography. RESULTS: The cardiopulmonary bypass time was 134.46 ± 19.03 minutes, aortic cross-clamp time was 46.38 ± 8.57 minutes, and selective cerebral perfusion and lower body arrest time was 12.50 ± 2.19 minutes. There was 1 in-hospital death but no difficult bleeding from the distal aortic anastomosis. On postoperative computed tomography, the false lumen closed, with complete thrombus formation around the inserted fenestrated stent graft found in all survivors (100%), at the diaphragmatic level in 28 patients (70%), and at the superior mesenteric arterial level in 3 (8%). CONCLUSIONS: An open fenestrated stent graft placement provided extensive primary repair of the thoracic aorta and a strong distal aortic stump during the conventional ascending aorta replacement for acute type A aortic dissection but did not increase the risk or technical difficulty of the operation.

RESUMO

During the bidirectional Glenn shunt procedure in small infants, the standard right-angle venous cannula is frequently placed in the innominate vein for establishing the temporary veno-atrial bypass without cardiopulmonary bypass, but it should be small enough to allow flow to pass around it from the internal jugular vein opposite to the side the cannula is directed. Small cannula may induce the inadequacy of venous drainage. We developed a modified right-angle venous cannula and placed it within the innominate vein for sufficient venous drainage. The standard right-angle venous cannula was simply modified by an oval open on the top of the external curvature. Our initial application demonstrated that this modified venous cannula provides better venous drainage during the bidirectional Glenn shunt procedure without cardiopulmonary bypass in small infants.

RESUMO

OBJECTIVE: To make the open placement of the triple-branched stent graft technique suitable for most patients with acute type A aortic dissection to achieve effective individual total arch repair, we developed a self-adaptive triple-branched stent graft and arch open technique. In this study, we report the clinical experience and outcomes of total arch repair using implantation of this self-adaptive triple-branched stent graft with the aid of the arch open technique. METHODS: Between December 2012 and July 2014, 105 consecutive patients with acute type A aortic dissection with indications of total arch repair underwent total arch repair using implantation of a self-adaptive triple-branched stent graft with the aid of the arch open technique under hypothermic cardiopulmonary bypass and selective cerebral perfusion. Survivors were followed up prospectively by means of computed tomography angiography. RESULTS: The cardiopulmonary bypass time was 169.37 ± 27.17 minutes, aortic crossclamp time was 60.48 ± 16.72 minutes, and selective cerebral perfusion and lower body arrest time was 28.95 ± 7.23 minutes. The in-hospital mortality was 4.76%. One patient was lost to follow-up. One sudden death of unknown cause occurred 10 months after surgery. On the 3-month postoperative scans, the false lumen closed with complete thrombus formation around the self-adaptive triple-branched stent graft was found in all survivors and at the diaphragmatic level in 71.72% of patients. CONCLUSIONS: The simple implantation of a self-adaptive triple-branched stent graft with the aid of the arch open technique can be used safely in most patients with acute type A aortic dissection for effective individual total arch repair.

RESUMO

OBJECTIVE: To summarize the clinical experiences and midterm follow-up results of total arch repair with open triple-branched stent graft placement for acute type A aortic dissection. METHODS: From June 2008 to March 2013, 122 patients (95 men and 27 women; mean age, 50.9 ± 10.4 years) with acute type A aortic dissection underwent total arch repair with open placement of a triple-branched stent graft under hypothermic cardiopulmonary bypass and selective cerebral perfusion. During the follow-up period, enhanced computed tomography and echocardiography were performed at 3 months postoperatively and annually thereafter. RESULTS: Placement of the triple-branched stent graft into the true lumen of the descending aorta, arch, and 3 arch vessels was technically successful in 121 patients. The cardiopulmonary bypass time was 186.50 ± 38.23 minutes, and the selective antegrade cerebral perfusion time was 31.97 ± 10.08 minutes. The in-hospital mortality was 4.93%. No permanent neurologic dysfunction or paraplegia was observed. Three patients were lost to follow-up. The mean follow-up period was 30.24 ± 12.35 months. After hospital discharge, 3 patients died. On the 3-month postoperative scans, complete thrombus formation around the triple-branched stent graft was observed in 89.38% of the patients. Endoleaks were detected in 12 patients; 8 patients refused any management for the endoleaks, but they maintained a good quality of life. The other 4 patients were successfully treated by additional surgery. CONCLUSIONS: Total arch repair with open triple-branched stent graft placement is an effective technique with satisfactory early and midterm results. This technique could be an attractive alternative to conventional total arch replacement.

RESUMO

BACKGROUND: In total arch repair with open placement of a triple-branched stent graft for acute type A aortic dissection, the diameters of the native arch vessels and the distances between 2 neighboring arch vessels did not always match the available sizes of the triple-branched stent grafts, and insertion of the triple-branched stent graft through the distal ascending aortic incision was not easy in some cases. To reduce those two problems, we modified the triple-branched stent graft and developed the arch open technique. METHODS AND RESULTS: Total arch repair with open placement of a modified triple-branched stent graft and the arch open technique was performed in 25 consecutive patients with acute type A aortic dissection. There was 1 surgical death. Most survivors had an uneventful postoperative course. All implanted stents were in a good position and wide expansion, there was no space or blood flow surrounding the stent graft. Complete thrombus obliteration of the false lumen was found around the modified triple-branched stent graft in all survivors and at the diaphragmatic level in 20 of 24 patients. CONCLUSIONS: The modified triple-branched stent graft could provide a good match with the different diameters of the native arch vessels and the various distances between 2 neighboring arch vessels, and it's placement could become much easier by the arch open technique. Consequently, placement of a modified triple-branched stent graft could be easily used in most patients with acute type A aortic dissection for effective total arch repair.
