Pseudoaneurysms of the superficial temporal artery (STA) are rare vascular lesions that mainly occur after blunt head trauma. Diagnosis can be made on clinical grounds and is confirmed by ultrasonography. They are usually treated by open surgery procedures, but when the aneurysm is located in inaccessible areas, catheter embolization can be an alternative therapeutic option. We describe a case of a traumatic pseudoaneurysm of the STA which was treated with the vascular plug embolization. We conclude that endovascular embolization can be an option in the treatment of STA pseudoaneurysms.

Background and ObjectivesAbdominal Aortic Aneurysm (AAA) and carotid disease have medical and social significance, considering their morbidity, disability, and economic consequences. The study objectives were to determine the prevalence of asymptomatic internal carotid artery (ICA) lesions ≥70% in patients with AAA, the correlation of AAA diameter with the degree of ICA stenosis and symptoms, and the importance of preventive ultrasound checkups.Subjects and MethodsA prospective non-randomized controlled study including 740 patients, aged from 18-85 years, who were suitable for the inclusion and exclusion criteria and reported at the vascular laboratory of the Institute for Vascular and Endovascular Surgery, Clinical Center of Serbia from 1st of December 2011 to the 1st of November 2012.ResultsThe prevalence of asymptomatic ICA stenosis ≥70% in patients with AAA is 10.8%. Male representatives have more symptomatic ICA stenosis ≥70%. Patients with small aneurysms more often have asymptomatic ICA stenosis ≥70%. The occurrence of symptoms of carotid disease was more prevalent among patients with ICA stenosis ≥70% compared to the group with stenosis <70%. There was no correlation found between the grade of ICA stenosis with the size of AAA.ConclusionThe prevalence of asymptomatic ICA stenosis ≥70% in patients with AAA is found to be 10.8%. Male patients with ICA stenosis ≥70% more often had symptoms of carotid disease. In the smaller aneurysms, ICA stenosis ≥70% occurs frequently, but without the symptoms of carotid disease, and there was no correlation between the size of AAA and the grade of ICA stenosis. Clinical implications of ICA imaging in patients with previously diagnosed AAA is necessary.

The incidence of concomitant extracranial carotid artery stenosis and ipsilateral intracranial carotid aneurysm has been reported to vary between 2.8% and 5%. These complex lesions may present a challenge for treatment decision-making. This case report describes an asymptomatic male patient with severe carotid bifurcation stenosis, coupled with an unruptured supraclinoid internal carotid aneurysm. Both lesions were treated simultaneously. Patient underwent carotid stenting followed by aneurysm coiling in the same setting without any complication.

Background Coronary collateral circulation exerts protective effects on myocardial ischaemia due to coronary artery disease and can be promoted by exercise with heparin co-administration. Whether this arteriogenetic effect is accompanied by functional improvement of left ventricle during stress and lessening of angina symptoms remains unknown. Aims To evaluate the anti-ischaemic efficacy of heparin plus exercise in coronary artery disease. Methods In a prospective, single-centre, randomized, double-blind study we recruited 32 ‘no-option’ patients (27 males; mean age 61 ± 8 years) with stable angina, exercise-induced ischaemia and coronary artery disease not suitable for revascularization. All underwent a two-week cycle of exercise (two exercise sessions per day, five days per week) and were randomized ( n = 16 per group) to intravenous placebo (0.9% saline) versus unfractionated heparin (5.000 IU intravenously), 10 min prior to exercise. We assessed Canadian Cardiovascular Society angina class, stress electrocardiogram and echo parameters (wall motion score index) and computed tomography angiography for collaterals. Results After two-week cycle, Canadian Cardiovascular Society class statistically decreased in both groups (heparin plus exercise group: 2.6 ± 0.7 to 1.9 ± 0.7, p < 0.001, exercise group: 2.4 ± 0.7 to 2.1 ± 0.9, p = 0.046). Only the heparin plus exercise group improved time-to-ST segment depression (before 270, 228–327 s vs. after 339, 280–360 s, p = 0.012) and wall motion score index (before 1.38 ± 0.25 vs. after 1.28 ± 0.18, p = 0.005). By multi-slice computed tomography angiography, collaterals improved in 12/15 (80%) in the heparin plus exercise group versus 2/16 (12.5%) in the exercise group ( p < 0.001). Conclusion A two-week, 10-test cycle of heparin plus exercise is better than exercise in improving angina class, myocardial ischaemia and collaterals by computed tomography angiography.
