Gastroschisis - current options for prenatal diagnosis and subsequent management.

Gastroschisis is a congenital abdominal wall defect characterized by the eventration of bowel loops through a right-sided paraumbilical opening. Prenatal detection of gastroschisis is generally straightforward due to advanced ultrasound techniques, and it is essential for optimizing both prenatal care and subsequent management. The prognosis for this condition is generally favorable, with positive long-term outcomes for most children.

Sacrococcygeal teratoma - prognosis based on prenatal ultrasound diagnosis, single-center experience and literature review.

Introduction: Sacrococcygeal teratoma (SCT) is the most common congenital tumor. The incidence of malignant types is rare but increases with late detection or in case of relapse. Prenatal diagnosis is based on ultrasound examination and magnetic resonance imaging (MRI).

Prenatal diagnosis in estimating the prognosis of sacrococcygeal teratoma.

: Sacrococcygeal teratoma is a rare congenital malformation, the prognosis depends on factors affecting foetal development. The diagnosis is based on ultrasound examination, especially the evaluation of the detailed morphology of the foetus in the 20th week of pregnancy. Therefore, it is crucial to keep looking for ultrasound markers that would prenatally determine the most accurate prognosis for the foetus.

Study protocol of a prospective single-arm multicenter clinical study to assess the safety and performance of the aXess hemodialysis graft: The pivotal study.

Background: Arteriovenous grafts (AVGs) are used for patients deemed unsuitable for the creation of an autogenous arteriovenous fistula (AVF) or unable to await maturation of the AVF before starting hemodialysis. However, AVGs are prone to infection and thrombosis resulting in low long-term patency rates. The novel aXess Hemodialysis Graft consists of porous polymeric biomaterial allowing the infiltration by cells and the growth of neotissue, while the graft itself is gradually absorbed, ultimately resulting in a fully functional natural blood vessel.

Six-year outcomes of a phase II study of human-tissue engineered blood vessels for peripheral arterial bypass.

Objective: The human acellular vessel (HAV) was evaluated for surgical bypass in a phase II study. The primary results at 24 months after implantation have been reported, and the patients will be evaluated for ≤10 years.

Methods: In the present report, we have described the 6-year results of a prospective, open-label, single-treatment arm, multicenter study.

Five Year Outcomes in Patients with End Stage Renal Disease Who Received a Bioengineered Human Acellular Vessel for Dialysis Access.

Objective: Patients with end stage renal failure who require haemodialysis suffer morbidity and mortality due to vascular access. Bioengineered human acellular vessels (HAVs) may provide a haemodialysis access option with fewer complications than other grafts. In a prospective phase II trial from 2012 to 2014 (NCT01744418), HAVs were implanted into 40 haemodialysis patients at three sites in Poland.

Strategy of pulseless pink supracondylar humerus fracture treatment in children: a comparison of two approaches.

Purpose: The appropriate treatment of pulseless pink supracondylar humerus fractures (SCHF) remains controversial. In this study, the outcomes of two treatment approaches (with and without vascular surgery) were compared.

Material And Methods: This was a retrospective multicenter study of patients with pulseless pink SCHFs treated in ten pediatric surgery, trauma, or orthopedics departments in the Czech and Slovak Republic between 2014 and 2018.

Arterial reconstruction with human bioengineered acellular blood vessels in patients with peripheral arterial disease.

Objective: Vascular conduit is essential for arterial reconstruction for a number of conditions, including trauma and atherosclerotic occlusive disease. We have developed a tissue-engineered human acellular vessel (HAV) that can be manufactured, stored on site at hospitals, and be immediately available for arterial vascular reconstruction. Although the HAV is acellular when implanted, extensive preclinical and clinical testing has demonstrated that the HAV subsequently repopulates with the recipient's own vascular cells.

The ultrasonography evaluation of talar dysplasia as a potential prognostic factor for predicting the course and outcomes of clubfoot deformity treatment using Ponseti technique.

Objective: The aim of this study was to assess the role of sonographic evaluation of Talar dysplasia in predicting the outcome of standard Ponseti method in the treatment of clubfoot deformity.

Methods: A total 23 children (15 boys and 8 girls; mean age: 18.2 ± 5.

Contrast Media Administration in Coronary Computed Tomography Angiography - A Systematic Review.

 Various different injection parameters influence enhancement of the coronary arteries. There is no consensus in the literature regarding the optimal contrast media (CM) injection protocol. The aim of this study is to provide an update on the effect of different CM injection parameters on the coronary attenuation in coronary computed tomographic angiography (CCTA).

Bioengineered human acellular vessels for dialysis access in patients with end-stage renal disease: two phase 2 single-arm trials.

Background: For patients with end-stage renal disease who are not candidates for fistula, dialysis access grafts are the best option for chronic haemodialysis. However, polytetrafluoroethylene arteriovenous grafts are prone to thrombosis, infection, and intimal hyperplasia at the venous anastomosis. We developed and tested a bioengineered human acellular vessel as a potential solution to these limitations in dialysis access.

Evaluation of individually body weight adapted contrast media injection in coronary CT-angiography.

Objectives: Contrast media (CM) injection protocols should be customized to the individual patient. Aim of this study was to determine if software tailored CM injections result in diagnostic enhancement of the coronary arteries in computed tomography angiography (CTA) and if attenuation values were comparable between different weight categories.

Materials And Methods: 265 consecutive patients referred for routine coronary CTA were scanned on a 2nd generation dual-source CT.

Automated Tube Voltage Selection for Radiation Dose Reduction in CT Angiography Using Different Contrast Media Concentrations and a Constant Iodine Delivery Rate.

Objective: The purpose of this study was to systematically investigate radiation dose reduction using automated tube voltage selection during CT angiography (CTA) and to evaluate the impact of contrast medium (CM) injection protocols on dose reduction.

Materials And Methods: A circulation phantom containing the thoracic and abdominal vasculature was used. Four different concentrations of CM (iopromide 300 and 370 mg I/mL and iomeprol 350 and 400 mg I/mL) were administered while maintaining an identical iodine delivery rate (1.

Robot-assisted right colectomy: surgical technique and review of the literature.

Following the successful introduction of robotic surgery to the field of urology and gynecology, its use gained even more interest among those in the field of colorectal surgery. Rectal resection is believed to be among the best suited for robotic assistance. In particular, the right hemicolectomy procedure has been proposed as a training tool in order to gain clinical experience with the robot.
