RESUMO

INTRODUCTION: There are enough cases of colorectal cancer with liver metastasis, but inferior vena cava infiltraion with dissemination to the right atrium is an infrequent event. PRESENTATION OF CASE: This is the first case of surgical treatment of recurrent liver metastasis with the infiltration to the inferior vena cava and to the right atrium of the heart, using a cryopreserved pulmonary homograft. DISCUSSION: The choice of a cryopreserved pulmonary homograft was preferred by the need for a radical and wide resection of tissues involved in the metastasis, as well as to potentially reduce the risk of thrombosis in the short- and long-term postoperative period. CONCLUSION: The use of a cryopreserved homograft in operation undergoing cardiopulmonary bypass allowed us to perform the required volume of radical resection and to replace an extended section of the inferior vena cava.

RESUMO

BACKGROUND: Perfect heart valve prostheses have optimized hemodynamics, reduced surgical morbidity, long-lasting durability, and extended patient survival with greater quality of life. Mechanical valves are recommended; however, young children may need anticoagulant medication for life. In this study, we looked at the success rate and viability of aortic valve neocuspidization (AVNeo) surgery for a variety of aortic disorders. METHODS: A methodical search strategy was used to fully evaluate the AVNeo results. Boolean operators were used to combine important words like 'Ozaki Procedure,' 'Aortic Valve Neocuspidization,' 'AVNeo,' and associated terms. Reputable databases such as PubMed, MEDLINE, Embase, Web of Science, and Scopus were the focus of our search. Study quality was assessed using a critical evaluation created with the Critical Appraisal Skills Programme tool. RESULTS: The findings are summarized in the 'Results' section that contains descriptive and critical analysis, ramifications, and explanations. According to research, AVNeo improved valve function and had few side effects. Aortic valve neocuspidization has a lower mean pressure gradient and a larger mean efficient orifice area than Trifecta. Aortic valve neocuspidization surgery reduces aortic valve regurgitation and pressure gradients. Postoperative echocardiograms indicated a decrease in peak and a rise in mean pressure gradient. CONCLUSION: The Ozaki method restores a healthy laminar flow pattern while preventing bivalvular disease. Ozaki procedure should be explored for valve repair in infants with truncal valve and congenital aortic disease. Aortic valve tricuspidization with glutaraldehyde-treated autologous pericardium results in considerable effective orifice area, modest pressure gradients, and little regurgitation.

RESUMO

OBJECTIVE: Renal cell carcinoma with inferior vena cava thrombosis is a rare disease with a poor prognosis without surgical treatment. We report our 11-year experience in the surgical treatment of renal cell carcinoma with extension of the inferior vena cava. METHODS: We conducted a retrospective analysis of patients undergoing surgical treatment for renal cell carcinoma with invasion of the inferior vena cava in two hospitals from May 2010 to March 2021. To assess the spread of the tumor process invasion, we used the Neves and Zincke classification. RESULTS: A total of 25 people underwent surgical treatment. Sixteen patients were men, nine were women. Thirteen patients underwent cardiopulmonary bypass (CBP) surgery. The following postoperative complications were recorded: two cases of disseminate intravascular coagulation (DIC), two cases of acute myocardial infarction (MI) and one case of coma of unknown reason, Takotsubo syndrome and postoperative wound dehiscence. Three patients deceased (16.7%) of DIC syndrome and AMI. After discharge, one of the patients had a recurrence of tumor thrombosis 9 months after surgery, and another patient had the same 16 months later, presumably due to the neoplastic tissue in the adrenal gland on the contralateral side. CONCLUSION: We believe that this problem should be dealt with by an experienced surgeon with a multidisciplinary team in the clinic. The use of CPB provides benefits and reduces blood loss.

RESUMO

Marfan syndrome is an autosomal dominant disease of connective tissue affecting approximately one in 5 000 people. However, the majority of patients (60-80%) with Marfan syndrome have some degree of aortic root dilation or thoracic aortic aneurysm that can lead to aortic dissection and rupture, which has long been recognised as the leading cause of death in Marfan syndrome. The funnel breast (pectus excavatum), often seen in patients with Marfan syndrome, radically complicates the access during aortic root or arch interventions, forcing cardiosurgery practitioners to seek alternative approaches. We present a series of clinical observations of two patients with Marfan syndrome and aneurysm of the aortic root and ascending aorta. A left-sided thoracotomy provides the possibility of successful implementation of extensive surgical interventions, decreasing the risks of intra-operative damage to the cardiac structures adjacent to the sternum in this complex cohort of patients.

RESUMO

Primary pulmonary artery sarcoma is a rare disease with poor prognosis. Radical resection provides the best curative chances. Our 60-year old male patient underwent pulmonary artery sarcoma excision with pericardial patch repair of the main pulmonary artery in 2017, but required reoperation in 2019 due to recurrence. Total pulmonary artery bifurcation replacement was performed using a handmade 2-limbed bovine pericardial tube graft. This technique is safe and reproducible, and may offer a valuable alternative surgical strategy for this patient cohort. Our patient is still alive 4 years after initial presentation.

RESUMO

INTRODUCTION: Giant thoracic aortic aneurysms and aortic arch dissections are accompanied by high mortality rates, cardiac and neurologic events and pulmonary complications. Tracheobronchial compression with aorta-tracheal fistula is a rare complication of the aorta aneurysms. Aortic arch replacement in such case presents several formidable challenges. PRESENTATION OF CASE: This is the case report of successful surgical treatment of giant aortic arch aneurysm, complicated by airway compression, aorta-tracheal fistula and recurrent community-acquired pneumonia. DISCUSSION: Urgent indications for the aortic arch aneurysms surgery include significant size and high risk of rupture. As well as a visceral compression are presented. Bronchoscopy can be used to successfully treatment at all stages from trachea intubation to extubation. CONCLUSION: Aggressive surgical approach with careful pre-operative diagnostic are the key to success and the only one chance for patients with aortic arch aneurysm, complicated by airway compression.

RESUMO

INTRODUCTION AND IMPORTANCE: The infective endocarditis incidence data for patients undergoing aortic valve neocuspidization with glutaraldehyde-treated autologous pericardium (Ozaki procedure) are rare, and the optimal surgical treatment strategy remains unclear. CASE PRESENTATION: This is the first case report of surgical treatment of infective endocarditis of aortic valve with cryopreserved homograft in an athlete with previously performed Ozaki procedure. CLINICAL DISCUSSION: The choice of homograft was dictated by the young age of the patient; professional activity as an athlete; refusal of anticoagulants and the need for wide excision of compromised tissues to mitigate potential risk of spread of infection as well as its recurrence. CONCLUSION: The use of the aortic homograft allowed us to radically remove the infected tissues and achieve hemodynamic characteristics similar to the native valve. This is probably the first case report of use of homograft to treat aortic valve endocarditis following Ozaki procedure.

RESUMO

Cardiological patients with malignant tumors belong to a complex category of patients. We present the world's first case of simultaneous surgical treatment of severe mitral valve disease and esophageal cancer. The patient underwent simultaneous replacement of the mitral valve and the Ivor-Lewis procedure using right thoracotomy and upper midline laparotomy. The patient underwent 3 courses of chemotherapy (paclitaxel and 5-fluoroucil). Follow-up for 8 months showed no signs of tumor recurrence or cardiac problems. A dextral thoracotomy with the lung deprivation, supplemented by an upper median laparotomy, achieved us convenient access to the mitral valve and to all parts of the esophagus, including groups of compromised lymph nodes. This case demonstrates the modern possibilities of simultaneous cardio and oncosurgery that allows eliminating competitive fatal diseases in 1 surgical and anesthetic intervention.

RESUMO

OBJECTIVE: To examine the results of various myocardial revascularization techniques in pediatric patients to better understand the strategies for surgical treatment of coronary artery pathologies. METHODS: We analyzed 61 publications dedicated to the indications, methods, and results of coronary bypass surgery in children. Due to the small size of this cohort, case reports are also included in our review. RESULTS: The main indications for coronary bypass grafting in children are Kawasaki disease, myocardial revascularization as a necessary procedure during the congenital cardiac surgery, to manage intraoperative iatrogenic damage to coronary arteries, and homozygous familial hypercholesterolemia. The use of internal thoracic arteries as conduits for coronary bypass grafting in children with Kawasaki disease showed significantly better results in long-term functionality compared to autovenous conduits (87% and 44%, respectively, P<0.001). Acute and late coronary events after arterial switch operation for the transposition of the great arteries, anomalous origin of the left coronary artery from the pulmonary artery, and left main coronary artery atresia are the main congenital heart diseases where surgical correction involves interventions on the coronary arteries. CONCLUSION: The internal thoracic artery is a reliable and durable conduit that demonstrates proven growth potential in children.

RESUMO

OBJECTIVE: To determine the feasibility of aortic valve neocuspidization (AVNeo) with glutaraldehyde-treated autologous pericardium. METHODS: One hundred and seventy (170) AVNeo (84 males/86 females) were performed from January 2017 through March 2019 in three centers. All the records were prospectively collected and retrospectively reviewed. RESULTS: Most of the patients were older than 60 years and over 95% were operated for aortic stenosis. Preoperatively, pressure gradients were 69.9±21.3 mmHg for patients with aortic stenosis, and the surgical annular diameter was 21.0±2.0 mm for all patients. Effective orifice area (EOA) and indexed EOA (iEOA) averaged 0.7±0.3 cm2 and 0.4±0.2 cm2/m2 for patients with aortic stenosis before surgery, respectively. There was no conversion to prosthetic aortic valve replacement. Eight patients needed reoperation for bleeding, but no patient needed reoperation due to early infective endocarditis. There were five in-hospital deaths due to noncardiac cause. Compared to preoperative echocardiographic measurements, postoperative peak pressure gradient decreased significantly (-58.7±1.7 mmHg; P<0.001) and reached 11.2±5.6 mmHg, and mean pressure gradient also decreased significantly (-36.8±1.1 mmHg; P<0.001) and reached 6.0±3.5 mmHg. Accordingly, EOA and iEOA increased significantly 2.0 cm2 and 1.0 cm2/m2 (both P<0.001) to reach 2.7±0.6 cm2 and 1.4±0.3 cm2/m2 after surgery, respectively, with minimal significant aortic regurgitation (0.6% > mild). CONCLUSION: AVNeo is feasible and reproducible with good clinical results. Hemodynamically, AVNeo produces immediate postoperative low-pressure gradients, large EOA, and minimal regurgitation of the aortic valve. Further studies are necessary to evaluate mid- and long-term evolution.
