Endovascular Repair of a Right Subclavian Artery Aneurysm with Coil Embolization and Stent Graft: Case Report and Literature Review.

Subclavian artery aneurysms (SAAs) may be clinically asymptomatic or present with symptoms ranging from pain to upper limb ischemia, posterior circulation ischemia, or, most seriously, life-threatening rupture and hemorrhage. In recent years, endovascular treatment has been extensively employed as an alternative for treating SAAs with favorable anatomy, especially in patients who are not candidates for surgery. We report a case of successful endovascular treatment of SAA with coil embolization and stent graft.

Transplantation of autologous bone marrow mononuclear cells for patients with lower limb ischemia.

Background: Many treatment options for lower limb ischemia are difficult to apply for the patients with poor arterial outflow or with poor general conditions. The effect of medical treatment alone is far from ideal, especially in patients with diabetic foot. A high level amputation is inevitable in these patients.
