[Proposal of a human cadaveric model for bedside ultrasound-based pneumothorax detection.].

Introduction: In the last decade, the use of bedside ultrasound examination has become one of the defining elements of emergency and intensive-anesthesia care. Among the everyday applications, lung ultrasound examination, which received a huge boost in connection with the coronavirus pandemic, stands out in a profession-specific manner. The first step of the most frequently used protocols is the immediate diagnosis of life-threatening conditions (e.

Minimally invasive apical cannulation and cannula design for short-term mechanical circulatory support devices.

Background: Refractory cardiogenic shock is still a major clinical challenge with high mortality rates, although several devices can be used to conquer this event. These devices have different advantages and disadvantages originating from their insertion or cannulation method, therefore many complications can occur during their use. The aim of our study was to develop and create prototypes of a novel minimal invasively insertable, transapical cannula for surgical ventricular assist devices, which uniquely incorporates the inflow and outflow routes for the blood of the patient in itself, therefore it enables the use for only one cannula for patients in cardiogenic shock.

[Rare variation of hepatic blood supply with accessory right and left hepatic artery].

In recent decades, multiple studies have examined the various manifestations of the hepatic blood supply using anatomical preparation and imaging procedures (angiography, CT). Based on these observations, several classifications have emerged to determine blood supply types and their incidence rates. Our aim is to present a rare variation of the arterial blood supply of the liver through an anatomical preparation.

Traumatic lesions at the thumb base: Treatment options.

Traumatic lesions around the base of the thumb have special features due to the location and structure of the joint and its inherent potential instability. This causes different fracture patterns, which are mostly isolated around the metacarpal base but can also involve just the trapezium or both. Exceptionally, there may be isolated dislocation.

Human Cadaveric Artificial Lung Tumor-Mimic Training Model.

An important phase in surgical training is gaining experience in real human anatomical situations. When a cadaver is available it may complement the various artificial practice models. However, it is often necessary to supplement the characteristics of the cadavers with a simulation of a tumor.
