Woven coronary artery is extremely rare. It is characterised by thin channels arising from the coronary artery and reanastamosis at the distal portion. A 62-year-old man was diagnosed of coronary artery disease. Coronary angiography showed 3-vessel coronary artery disease. The distal right coronary artery derived 3 twisting thin channels, and the inferior thin channel sprouted second-class thin channels, which then reanstomosed distally. He received off-pump coronary artery bypass. The present patient had woven coronary artery with a more complex configuration of thin channels different from the previously reported cases.

The aim of the study was to investigate the distribution of the circle of Willis variants in Polish population by means of computed tomography angiography (CTA). The results were then analysed and compared with another study that used similar methods but that was carried out on an ethnically distinct population. Patients presenting with intracranial pathology were excluded from the initial study population. In total, 250 CTA belonging to 129 female and 121 male patients were reviewed. A modified classification system of the circle was proposed, which took into consideration the anterior and the posterior aspects of the circle individually. The typical variant of Willis’s circle occurred in 16.80% of cases. The anterior and the posterior portions of the circle were normal in 47.20% and 26.80% of the patients respectively. As for the anterior part, lack of the anterior communicating artery was the most frequent abnormality (22.80%). Bilateral absence of posterior communicating arteries was the most common anomaly in the posterior part of the circle (29.20%). This type of anomaly was also the most common, when taking into consideration the entire circle (12.00%). There were statistically significant differences between the age groups and genders when considering the occurrence of an incomplete circle. Overall, a substantial proportion of patients manifested clinically important variants that were incapable of providing collateral circulation. Comparison with other imaging-based and cadaveric studies revealed noticeable differences, that may have resulted from the variable technical features of other studies or other factors such as the ethnical origins of the studied populations.

The anterior tibial artery is of great clinical relevance to vascular infrapopliteal surgery. The sources (origins), length and luminal diameter of the anterior tibial artery in 46 men and 30 women with Lerich syndrome were studied by means of radiological and digital methods. The results obtained were described by twoway analysis of variance (Multi-group ANOVA) for unpaired data — the means for six subtypes with regard to sex and side of the body, using the STATISTICA 5.5 program. The anterior tibial artery occurred most frequently (92.11%) as a terminal branch of the popliteal artery in its normal (IA: 87.5 %, IB: 2.63%) and high (IIA 1: 1.32%, IIA 2: 0.66%) division. In the remainder (7.89%), the anterior tibial artery arose from both the anterior tibioperoneal trunks (IC: 1.97%, IIB: 5.92%). The statistical analysis of the sources of the anterior tibial artery did not show gender differences. Symmetry of the left and right popliteal patterns was observed in the two most frequent subtypes: IA (r₁ = 0.80) and IIB (r₂ = 0.83). The anterior tibial artery was the longest (p = 0.02 for men, p = 0.04 for women) in subtype IIA 2. The greatest diameter of the anterior tibial artery was characteristic for a trifurcation (IB) and the smallest for subtype IIA 2 (p = 0.04). Both the length (p = 0.03) and luminal diameter (p = 0.04) of the anterior tibial artery in men were significantly greater than in women in all the popliteal subtypes observed. Morphometric parameters of the right and left anterior tibial artery showed no statistically significant differences. The anterior tibial artery was the predominant vessel in a trifurcation (IB) and in the two subtypes with an anterior tibioperoneal trunk (IC, IIB). These results have implications in vascular grafting below the knee.

As early as several days after the publication of the information concerning Roentgen's discovery the first radiological examinations were performed in Poland. The new method was immediately introduced into medical practice, including gastroenterology. In that pioneer period the most important works were those by Walery Jaworski who was the first man in the world to perform an X-ray of gall stones as well as the stomach with the use of a contrast medium. In its more-than-a-hundred-year history Polish gastrointestinal radiology has attempted not only to catch up with the world science, but it also has made a considerable contribution to its development.

Advances in 64-row multidetector computed tomography have provided noninvasive imaging of coronary arteries. The aim of this study was to evaluate the prevalence of coronary artery anomalies in Iranian symptomatic patients and to determine the presence of anomalies resulting in myocardial ischaemia without atherosclerotic plaque. This study was carried out in Tabriz University of medical sciences on 534 patients with suggestive symptoms for coronary artery diseases. Original slices were reconstructed from data achieved by using a ECG-gated multidetector computed tomography scanner, and reconstructed 3-dimentional images of the heart were reviewed. Congenital angiography was performed in 36.3% of patients. The prevalence of myocardial bridging in symptomatic patients was 6.0% by multidetector computed tomography while conventional angiography could detect 20% of them. The most prevalent site was the middle portion of the left anterior descending artery. Anomalous origin or course of coronary arteries and AV fistula was detected by multidetector computed tomography coronary angiography in 2.6% of cases while conventional angiography could detect 44.4% of these anomalies. The prevalence of atherosclerotic plaques in patients with myocardial bridging was 53.1%. In 46.9% of these patients, myocardial bridging was held responsible for signs and symptoms of myocardial ischaemia as no atherosclerotic plaque was evident. This rate was 64.3% in symptomatic patients with other anomalies in origin or course of coronary arteries. This study gives the prevalence of coronary artery anomalies and myocardial bridging in the Iranian population. The results suggest multidetector computed tomography coronary angiography as the preferred utility for diagnosing such anomalies. (Folia Morphol 2009; 68, 4: 201–206)
