Inflammatory abdominal aortic aneurysm accounts for 5% to 10% of all cases of abdominal aortic aneurysm and differs from typical atherosclerotic abdominal aortic aneurysm in many important ways. Although both inflammatory and atherosclerotic abdominal aortic aneurysms most commonly affect the infrarenal portion of the abdominal aorta, patients with the inflammatory variant are younger and usually symptomatic, chiefly from back or abdominal pain. Unlike patients with atherosclerotic abdominal aortic aneurysm, most with the inflammatoryvariant have an elevated erythrocyte sedimentation rate or abnormalities of other serum inflammatory markers. Computed tomography and magnetic resonance imaging are both sensitive for demonstrating the cuff of soft tissue inflammation surrounding the aneurysm that is characteristic of inflammatory abdominal aortic aneurysm. Inflammatory abdominal aortic aneurysm can be primarily infected by degenaration of an infected artery (in less than 1% of cases), or can become secondary infected in the already existing aneurysm. Seconadary infection of the pre-existing aneurysm has big inffluence on treatment choice, but is also rare. Clinically non-symptomatic infection, also known as bacterial collonisation, can be very frequent, regarding a greatly increased number of positive intraoperative findings (10-15%). Prolonged intravascular catheterization, vascular grafting, repeated punctures with large bore needles, and decreased immune defence mechanism make uraemic patients undergoing haemodialysis more likely to develop Staphylococcus aureus bacteraemia and its complications. ⋯ There were no postoperative complications, and the final outcome was fully satisfactory. Control CT scans after 3, 6 and 12 months were regular, with signs of regression fibrosis of the retroperitoneum.,

Cardiovascular autonomous neuropathy (CAN) in diabetes has not been still defined clinically and aetiopathogenetically. ⋯ Our results show that besides disease duration, the subacute deterioration of glycoregulation also leads to the appearance of cardiovascular autonomous dysfunction in diabetes. The sympathetic nervous tissue is functionally more sensitive than the parasympathetic one to metabolic disorders in diabetes. The cardiovascular autonomous dysfunction will occur independently of the type of diabetes.

The risk of cardiovascular disease in patients with chronic renal disease appears to be far greater than in the general population and the risk of cardiovascular death is much higher than the risk of eventually requiring renal replacement therapy. Heart failure is important finding and it is evident even before the initiation of dialysis; the frequency of heart failure is 10 to 30 times higher in patients on dialysis than in the general population. Left ventricular hypertrophy has incidence of nearly 75-80% and is closely related to heart failure, ventricular arrhythmias, fatal myocardial infarction, aortic root dilatation and cerebrovascular event. ⋯ Patients on dialysis are prone to calcification of media and intima due to disbalance of promoters and inhibitors of calcification process. Now, there are no valid data about the privilege of one dialysis method over another in cardiovascular morbidity and mortality. Numerous traditional and non-traditional risk factors urge for preventive measures for cardiovascular diseases in patients with chronic renal diseases.

Aneurysms of digital arteries are considered to be rarity. They could be true or false. False aneurysms are usually the result of penetrating trauma, while the causes of development of true aneurysms are various, such as blunt trauma, and rarely atherosclerosis, vasculitis and infection. Also, they can be idiopathic. Reviewing the literature we found 13 cases of previously described true aneurysms of digital arteries. None of them referred to the common digital artery aneurysm. ⋯ As mentioned above, true aneurysms of digital arteries are very rare, so they are of little clinical importance. The most common symptom of digital artery aneurysms is pain, with a tender pulsatile mass on examination. Since natural healing cannot be expected, surgical treatment of true digital artery aneurysms is recomended for pain relief and avoidance of complications which may occur and are related to the aneurysm presence. Aneurysm resection and ligation of a blood vessel can be performed. Also, artery reconstruction can be performed by primary end-to-end anastomosis or the placement of a reversed interposition vein graft.

Mortality in ST elevation myocardial infarction (STEMI) ranges from 4-24% and is dependent on the variety of patients' clinical characteristics (CC) that are present prior to and within the first hours of the onset of MI, affecting reliability of the diagnosis. The higher mortality rate of patients with STEMI should be associated with a higher rate of applied reperfusion therapy according to guidelines and randomized study results, which is in opposition to everyday hospital practice. ⋯ Clinical characteristics significantly influence mortality in STEMI; a significantly higher mortality is among women, patients in their 80's and 90's, anterior MI localization and prior coronary disease. RT significantly lowers mortality in STEMI compared to the use of classical therapeutic approach and therefore STEMI patients with a higher mortality determined by their prehospital charactheristics, i.e. higher risk, are those who have higher benefit of RT, which should be taken into consideration when making decision about the therapy of choice.
