Preoperative and Postoperative Arterial Adaptation in Patients with Acute Aortic Dissection.

Spinal cord ischemia is one of the most serious complications after an aortic repair. To date, there is no evidence for arterial changes during an aortic dissection or for the observation of such arteries after an aortic repair. The aim of this study was to compare spinal-cord-supplying arteries in patients with an acute aortic dissection, preoperatively and postoperatively, with patients without an acute aortic dissection.

Multiple coexisting variations of skull and cervical spine anatomy in a symptomatic patient - uncommon or uncommonly noticed? A CT-based case study.

Introduction: Among many anatomical variations of the skull and cervical spine, some may be an underlying cause of a disease, while others remain clinically silent. The estimated individual prevalences of them differ, but given the available data it is impossible to clarify how frequently they coexist with each other. The following study presents an example of seven anomalies, amongst which at least few have manifested clinically in the examined patient.

Prevalence of the Onodi cell in the Polish adult population: an anatomical computed tomography study.

Background: Onodi cell is a posterior ethmoid air cell with the optic canal bulging into it; the common position of the bulge is into the sphenoid sinus, usually immediately posterior to the posterior ethmoid air cells. Variable pneumatisation patterns lead to various structures of lamellae and sinuses occasionally exposing important nerves and vessels, such as the optic and vidian nerves, internal carotid artery and cavernous sinus. In clinical practice, special imaging techniques are used to navigate through the paranasal sinuses and hence avoid injury to these structures.

Extensive pneumatisation of the sphenoid bone: anatomical investigation of the recesses of the sphenoid sinuses and their clinical importance.

Background: There is a great variance between the extents of pneumatisation of the sphenoid sinuses that can reach beyond the body of the sphenoid bone. The purpose of this study was to find the prevalence of the recesses of the sphenoid sinuses in Polish adult population.

Materials And Methods: Two hundred ninety-six computed tomography (CT) scans of patients who did not present any pathology in the sphenoid sinuses were evaluated in this retrospective analysis.

The total number of septa and antra in the sphenoid sinuses - evaluation before the FESS.

Purpose: The purpose of this research is to define the total number of septa and the total number of antra in the sphenoid sinuses (created as a result of the presence of additional septa), as well as the relation between the number of the septa and their location in the adult population.

Materials And Methods: e study was conducted as a retrospective analysis of the computed tomography (CT) scans of the paranasal sinuses of 296 patients (147 females and 149 males), who did not present any pathology in the sphenoid sinuses. The CT scans of the paranasal sinuses were done with the spiral CT scanner (Siemens Somatom Sensation 16) by using a standard procedure, in the option Siemens CARE Dose 4D, without using any contrast medium.

Autonomic nervous system of the pelvis - general overview.

Autonomic nervous system of the pelvis is still poorly understood. Every year more and more pelvic procedures are carried out on patients suffering from different pelvic disorders what leads to numerous pelvic dysfunctions. Authors tried to review, starting from historical and clinical background, the most important reports on anatomy of the pelvic autonomic plexuses.

Vascular density of inferior tibiofibular joint - cadaveric experimental study.

The study was carried out on 50 human lower legs obtained during autopsies (KBET: 122.6120.315.

Residua of thymus in the mediastinum - clinical aspects - cadaveric study.

The main goal of this study was to investigate possible residua of thymic tissue in 100 adult cadavers with no thoracic pathology known before, by dissection of standard locations of thymic tissue in perithyroid, periaortic, peritracheal and retrotracheal spaces, as well as areas located next to the course of phrenic, vagus and left recurrent laryngeal nerves. Thus obtained tissue samples were studied by two pathologists independently. The remnants of the thymic tissue were found in 61 out of 100 specimens studied.

[The Cracow Physicians Society and the medical faculty of Jagiellonian University--the past and the present].

The Cracow Physicians Society (CPS) since inception in 1866, maintain close liaison with the Faculty of Medicine of the Jagiellonian University by the person of president, board members and ordinary members of the Society who are also employees of the University. They share a number of common initiatives. Many distinguished professors are honorary members of the Society.

The venous system of the human foetal spinal cord. Scanning electron microscope of vascular corrosion casts.

The investigation was carried out on 16 human foetal cadavers at the age of 17-23 weeks from the time of conception. The foetal vascular system was injected with the synthetic resin MERCOX CL-2R and analysed in scanning electron microscope.The vascular system of the foetal spinal cord was studied.

Extra- and intracerebral course of the recurrent artery of Heubner.

Background: The aim of the current study was to analyse the extra- and intracerebral course of the recurrent artery of Heubner (RAH) to provide detailed information for neurosurgeons operating in this area.

Materials And Methods: The material for this study was obtained from cadavers (ages 31-75 years) during routine autopsies. A total of 70 human brains (39 male and 31 female) were examined.

Accessory spine of the foramen ovale.

The objective of this study was to provide morphometric analysis of an accessory spine that was found within the lumen of the foramen ovale, as well as to find out whether this structure could mechanically irritate the mandibular nerve. A bifid spine was perceived in the macerated skull of an adult individual. It was located in the anterior part of the left foramen ovale.

Detailed 3D-morphometry of the anterior communicating artery: potential clinical and neurosurgical implications.

Purpose: Although a site common for pathology and of great importance to the neurosurgeon, the three-dimensional (3D) morphometry of the anterior communicating artery (ACoA) has had incomplete descriptions in the literature.

Methods: Using a novel 3D digital-image computer data analysis system, 115 patients underwent evaluation of their ACoA based on DICOM files derived from CT angiography. Measurements included the length, internal diameter, volume, deviation index (DI) and tortuosity index (TI).

Three-dimensional morphometry of the A2 segment of the anterior cerebral artery with neurosurgical relevance.

Most prior morphometry data regarding the A2 segment of the anterior cerebral artery (ACA) have been based on cadaveric measurements. With newer imaging modalities, surgical techniques, and minimally invasive procedures, new standards for the anatomy of this vessel are necessary. A novel computer-based data system was used to analyze the three-dimensional (3D) morphometry of 230 A2 segments.

Interactive 3D stereoscopic digital-image analysis of the basilar artery bifurcation.

The goal of this study was to analyze morphometrical variations of the basilar artery bifurcation (BAB), so that physicians could map out a patients anatomical structure prior to delicate neurosurgical procedures. The CT-angio files of 98 patients ranging from 12 to 78 years of age were retrieved. These files were evaluated using Gradual Angiographic Image Data Analyzer (GAIDA) software, where a new interactive three-dimensional (3D) stereoscopic visualization method was used to reconstruct computer images of the BAB complex.
