RESUMO
Carotid endarterectomy is preferable for prevention of acute cerebrovascular accident associated with atherosclerotic lesions of internal carotid artery. Modern interest in minimizing local complications and small excisions is also actual in carotid surgery. The authors review the modern literature data on evolution of carotid arteries exposure. Cutaneous mini-incision, transverse skin incision and retrojugular approach are discussed. The authors consider the advantages and possible complications of each technique.

We report surgical treatment of 4 patients with superior mesenteric artery aneurysm. A comprehensive examination including Doppler ultrasound and CT angiography of visceral arteries made it possible to assess the features of vascular anatomy. In accordance with the peculiarities of upper mesenteric artery angioarchitectonics, open and endovascular methods were used. A differentiated approach made it possible to treat patients without any complications.

Neck paragangliomas are orphan diseases with incidence 1:30 000-1:100 000. Life expectancy is poor in patients with distant metastasis (5-year overall survival 11.8%), whereas 5-year overall survival in patients with regional metastasis is 76.8-82.4%. Meanwhile, there is still no any reliable tool for prediction of malignant potential of paraganglioma. Above-mentioned data indicate an importance of early diagnosis and timely treatment of neck paragangliomas. Total resection of tumor in ablastic conditions is a gold standard of treatment. However, surgery is associated with a high risk of neurovascular complications and requires multidisciplinary approach. Nevertheless, new knowledge dedicated to different aspects of pathogenesis of neck paraganglioma, diagnosis and treatment arise every year. This review is devoted to modern data on neck paragangliomas.
