The vertebrobasilar system is a part of the cerebral arterial circle (circle of Willis), which forms the collateral circulation of the brain. A 75-year-old Caucasian female was admitted to hospital because of a strong headache radiating to the neck. On the basis of a neurological examination, the patient was classified into group III of the Hunt and Hess scale. Subarachnoid haemorrhage and 2 aneurysms of the cerebral arteries were diagnosed during multidetector 64-row computed tomography and angiography. An asymmetrical fenestration of the proximal part of the basilar artery was also observed. The bleeding aneurysm locating at anterior communicating artery was diagnosed and clipped surgically by right fronto-parietal craniotomy. The second aneurysm was located just after the junction of the vertebral arteries on the wall of the basilar artery. The presented case firstly illustrates the asymmetric fenestration of the proximal part of the basilar artery coexisting with subarachnoid haemorrhage and 2 aneurysms of brain arteries. Such observation should increase diagnostic attention in the detection of possible associated aneurysms and can help in preventing complications during all endovascular treatment procedures.

Duplication of the inferior vena cava (IVC) is a congenital condition where there are 2 large vessels: right IVC (RIVC) and left IVC (LIVC) on both sides of the abdominal aorta. Here, we present 2 cases of duplicated inferior cava coexisting with rare morphology of left gonadal (ovarian/testicular) vein. Both were observed during multidetector 64-row computer tomography. In first case atherosclerotic, tortuous abdominal aorta models both inferior venae cavae. The shape of veins were more- (RIVC) and less-arcuate (LIVC). Two years ago, the patient had been diagnosed with pulmonary thromboembolism. In second case abdominal aortic aneurysm models both large veins. The RIVC has a highly right-arcuate shape, while the LIVC has a less left-arcade shape. Our observation would seem to be especially important, because the tortuous abdominal aorta changes the shape of both IVC, and may predispose them for thrombosis formation. The presented report precisely describes the topography and measurements of the vessels in the retroperitoneal area. The literature concerning this anomaly, potential clinical implications and vascular complications are reviewed and the possible practical aspects are discussed. A familiarity with the anatomy of the most common types of venous anomalies is crucial for all surgeons, urologists and oncologists to reduce the risk of severe haemorrhage during all abdominal procedures.

Background: Confirming the branching pattern of the deep femoral artery (DFA) is vital in planning radiological and surgical procedures involving the medial circumflex femoral artery (MFCA) and the lateral circumflex artery (LFCA). The aim of this study was to characterise the course and morphology of branches of the DFA. Materials and methods: The anatomical dissection included 80 lower limbs which were fixed in 10% formalin solution. A dissection of the femoral region was carried out according to a pre-established protocol, using traditional techniques. Morphometric measurements were obtained twice by two researchers. Results: Six types of medial and lateral femoral circumflex artery variations were distinguished. In type I, the DFA divides into the MFCA and the LFCA (observed in 45% of cases). In type II, the MFCA is absent and the LFCA origin normally from the DFA (18.75%). In type III, the MFCA arises from the femoral artery above the origin of the DFA, while the LFCA starts from the DFA (15%). Finally, in type IV, the LFCA arises from the femoral artery above the origin of the DFA, while the MFCA starts from the DFA (10%). In type V, the LFCA origin alone from the femoral artery below the origin of the DFA, while the MFCA origin from the DFA (7.5%), while in type VI (3.75%), both the MFCA and the LFCA origin from the femoral artery. The mean diameter of the femoral artery at the level of the DFA origin was greatest in type 2 (10.62 ± 2.07 mm) and the least in type 6 (7.90 ± 1.72 mm; p = 0.0317). The distance from inguinal ligament to where the DFA arose was the greatest in type 6 (78.24 ± 29.74 mm) and least in type 5 (28.85 ± 11.72 mm; p = 0.0529). Conclusions: The medial and lateral femoral circumflex arteries were characterised by high morphological variations. The diameter of the femoral artery at the level of inguinal ligament correlated with the diameter of the DFA and distance to where the DFA arises from femoral artery.
