[Endovascular recanalisation of subclavian artery stenotic-occlusive lesions].

Recently, percutaneous transluminal angioplasty (PTA) with stent placement has gained greater acceptance for the treatment of hemodynamically significant atherosclerotic lesions involving the brachiocephalic, subclavian and vertebral vessels. PTA is performed instead of extratoracic bypass surgery, which is associated with several risks and complications. Main indications for PTA and stent include short occlusions and elderly patients with increased surgical risk.

[Initial experience in endovascular treatment of abdominal aortic aneurysms in Bulgaria].

The abdominal aneurysm imposes prominent epidemiological impact due to its high incidence and life threatening complications. The first steps in endovascular treatment of abdominal aneurysms in Bulgaria are herein described. Five bifurcated and one straight stent-grafts were implanted in the ,,St.

[Endovascular procedures in case of cancers engaging the vessels of the small pelvis].

Cervix cancer is quite common nowadays. Its progress is followed by painful symptomatology, urosepsis, lymphedem, flebothrombosis and ischemia of the lower limbs. The surgical treatment and the following chemotherapy and radiotherapy causes proliferation of the fibroid tissue, which embraces and presses the vessels of the small pelvis.

[Diagnostic and treatment of carotid bodies tumors].

Unlabelled: Carotid body tumor is rare neoplasm (about 0,5 per cent of all tumors).[28]. The tumor arise from paraganglionic cells of carotid body, which develops from both mesodermal elements of the third branchial arch and neural elements originating from the neural crest ectoderm.

[Analysis of the results of femoro-popliteal arterial bypasses depending on the clinical stage of disease].

The strategy of treating infra inguinal arterial lesions according to the clinical Fontaine stage is very difficult and complicated. Critical limb ischemia is considered a strong indication for revascularization without delay. It is still not clear what operative treatment should be chosen for patients in Fontaine stage II.
