Vascular geometry of vertebrobasilar tree with and without aneurysm.

Aim: To examine a possible relationship between the variable vascular geometry of vertebrobasilar joint angle and basilar bifurcation angle as well as the diameters of these blood vessels.

Methods: The study included 60 adult patients, of both sexes, who were divided into two groups. One group (30) consisted of patients without aneurysm of vertebrobasilar tree, and another group (30) of patients with aneurysm.

Variations in diameters of vertebro-basilar tree in patients with or with no aneurysm.

Introduction: The morphological anatomy of the posterior circulation is very complex and variable. Aims of this research were to document the morphological anatomy of the posterior circulation along with variations in the Bosnian population, in patients with or without aneurysm. Measurements of the outer diameters of the vertebral artery, basilar artery and posterior cerebral artery were taken.

Intrahepatic transposition of bile ducts.

Objective. To describe the intrahepatic bile duct transposition (anatomical variation occurring in intrahepatic ducts) and to determine the frequency of this variation. Material and Methods.

[Anatomical variations of roots of the common bile duct].

Variations of extrahepatic bile ducts are the basis of hepatobilliar surgery, and they may be a problem during the surgical procedures. In this paper we present the results of our research, wich is conducted on 100 human livers. Common hepatic duct wich is formed by connecting of right hepatic duct and left hepatic duct is noticed in 92% of cases, and in 5% of cases was formed by tree bile ducts.

Martin-Gruber anastomosis and transposition in cubital tunnel.

This describes the indivisible anastomosis of the main stem of median nerve with ulnar nerve through cubital tunnel followed by the anomaly of ulnar artery that appears as superficial ulnar artery. Both anomalies are found during the anatomical dissection of a grown-up male cadaver, on his right arm. Such case is very rare as, in the literature available to us, it has not been described.

[Variable anatomy of the kidneys--relationship and incidence between anatomical and clinical three-dimensional image methods].

Unlabelled: Research has been done at a 150 pairs of the human adult kidneys (50 anatomical preparedness plus 100 patients) both sex, randomly chosen. Variations of the kidneys have been analyzed and their respect at a live ones, by clinical tree-dimensional "image"methods and lifeless one by anatomical macro dissection plus corrosive method.

Conclusion: At the most presence of noticed variation had into a size of the kidney, and the lowest one in the number of the kidneys.

The ventilatory patterns of the left upper lobe of lung.

Having knowledge on models of the bronchial tree branching, is of a special interest for clinical and surgical pulmology, because the hemilobectomy, segmentectomy and subsegmentectomy are always determined by intralobar, intrasegmental and intrasubsegmental bronchial ramification. Investigations were performed on 100 lungs of children and adults of both sexes, one day to 85 years old, randomly chosen. There are two main types of branching of the left upper lobe bronchus: the bifurcation pattern as dominant model in 74% and the trifurcation model found in 26%.

[Anatomic variations of the cystic duct and its junction with the common hepatic duct].

The ductus cysticus is variable in the length, position and the site where it enters the ductus hepaticus communis--the cystohepatic junction. The investigations were carried out on 100 livers (50 anatomical preparations and 50 patients) adults of both sexes, randomized trial. Main methods of the research were: anatomical macrodissection and analysis of the clinical radiograms.

[Variations in the position and point of origin of the vermiform appendix].

There were investigated variations of appendix vermiformis in the place of origin and position. The investigations were carried out on 50 human preparations of adults of both sexes, unintentional choice. The position and relation between intestinum caecum and appendix vermiformis were determined by forensic medical and pathoanatomical autopsy.
