Wilms' Tumor With Intra-Atrial Extension: Treatment and Management.

Wilms’ tumor is the most common renal cancer in children. It can grow for a long time without any characteristic symptoms, causing only fever, abdominal pain, nausea, or vomiting, which is the reason why it is often discovered accidentally. In 1% to 4% of the cases, nephroblastoma leads to complications in the form of intravascular and intra-atrial extension. We present a case of a five-year-old boy with Wilms’ tumor extending into the inferior vena cava, right atrium, and then prolapsing through the tricuspid valve into the right ventricle.

Surgical closure of patent ductus arteriosus in extremely low birth weight infants weighing less than 750 grams

BACKGROUND Patent ductus arteriosus (PDA) occurs more frequently in premature infants. Depending on the degree of prematurity, these children often have other serious comorbidities that could have a significant impact on surgical outcome. AIM This study aimed to evaluate the clinical results of surgical ligation of PDA in extremely low body weight preterm infants with birth weight below 750 g, and to identify risk factors of mortality. METHODS A total of 31 preterm infants with birth weight below 750 g and significant PDA were operated between 2006 and 2016 through posterolateral thoracotomy (n = 16) or with the use of video-assisted thoracoscopic method (n = 15). Mean weight at the time of surgery was 750.8 ± 104.7 g. The gestational age ranged from 22 to 32 weeks. Data were retrospectively analysed, and prospective 100% follow-up was performed. RESULTS In-hospital mortality was 25.8% (n = 8). The type of surgery had no influence on the results. During the follow-up period lasting 5.2 ± 2.5 years, two other patients died. One-year and five-year probability of survival was 77.4% and 74.2%, respectively. The predominant cause of death was acute heart failure. All patients with preoperative renal dysfunction died in the postoperative period. Moreover, Cox regression analysis revealed renal dysfunction as an independent risk factor of early death. CONCLUSIONS Preterm infants with birth weight less than 750 g and significant PDA are highly challenging patients. Despite the recent advances in perioperative management with neonates, surgery is still associated with a high early mortality rate irrespective of the applied method.

Conversion to thoracotomy of video-assisted thoracoscopic closure of patent ductus arteriosus

Introduction Posterolateral thoracotomy was the access of choice in surgical treatment of patent ductus arteriosus (PDA) for many years before the introduction of video-assisted thoracoscopic surgery (VATS). The latter is thought to reduce postoperative pain and improve musculoskeletal system status. However, it carries a potential risk of conversion to thoracotomy. Aim To evaluate the rate, reasons and outcomes of VATS conversion to thoracotomy in surgical PDA patients. Material and methods From 2012 to 2017, 112 children were qualified for VATS closure of symptomatic PDA. Among them, 19 (16.9%) with the median age of 19.4 months required conversion to thoracotomy. The predominant reasons for conversion, early mortality and morbidity as well as late survival were evaluated. Results The overall conversion rate was 16.9% with an evident learning curve as it decreased significantly from more than 20% at the beginning to approximately 10% in the last 2 years. The predominant reasons were incomplete PDA closure (n = 6; 31.6%) followed by ductal bleeding after clip application (n = 5; 26.3%) and inadequate visualization (n = 5). One child died 48 h after the surgery due to acute cardiopulmonary failure (mortality 5.9%). All patients required postoperative chest tube insertion, and two of them developed postoperative pneumothorax. Neither deaths nor severe adverse events were noted throughout the follow-up period. Conclusions The rate of VATS PDA closure conversion to standard thoracotomy features a learning curve. Although it must be considered as a serious complication, probably it does not negatively affect either early the mortality rate or long-term survival.

Thromboembolic complications after an ankle joint open fracture in a patient with a history of deep vein thrombosis in the lower limbs

A 55-year-old patient was admitted to the Department of Orthopedics due to an open fracture in the right ankle joint. On the seventh day of hospitalization the patient experienced a transient ischemic attack. During the next day, dyspnea, chest pain and a ‘rider’ type pulmonary embolism in the pulmonary trunk occluding both pulmonary arteries and its branches were diagnosed. The patient was transferred to the Department of Cardiac Surgery. He underwent pulmonary embolectomy for massive pulmonary, right and left atrial embolism, and left ventricular embolism. ASD II was closed during this procedure. Ultrasonography with Doppler was performed 6 days after the surgery and revealed deep vein thrombosis, so the patient was transferred to the Department of Vascular Surgery for temporary inferior vena cava filter placement at the time of orthopedic surgery. The next day after implantation of the filter, the lower limb was operated on, and 14 days after orthopedic surgery, the vena cava filter was removed.

Combined mitral valve replacement associated with the Bentall procedure, diaphragmatic hernia repair and reconstruction of the pectus excavatum in a 26-year-old patient with Marfan syndrome

A 26-year-old man with Marfan syndrome was admitted as an emergency patient with ascending aorta aneurysm, severe mitral and aortic regurgitation, diaphragmatic hernia and pectus excavatum. After completion of diagnostics a combined surgical procedure was performed.

STEMI-RVD SCALE: THE NEW TOOL TO RECOGNIZE RIGHT VENTRICULAR DYSFUNCTION IN PATIENTS WITH FIRST STEMI

Right ventricular (RV) function provides strong prognostic information in patients treated with PCI for myocardial infarction. Identifying accurate and reliable parameters for the assessment of the RV dysfunction (RVD) is still a challenge. The aim of this study was to attempt to develop an optimal
