Endovascular treatment of a left subclavian pseudoaneurysm induced by ingestion of a foreign body.

Subclavian artery-esophageal fistula is a life-threatening entity. It usually occurs in cases of an aberrant right subclavian artery. A fistula between a non-aberrant subclavian artery and esophagus is extremely rare and difficult to diagnose.

Does routine completion angiogram during embolectomy for acute upper-limb ischemia improve outcomes?

Background: Since 1963, Fogarty balloon catheter thromboembolectomy is usually adopted as the gold standard treatment for acute limb ischemia. As the success of the procedure depends on complete removal of all thromboembolic material, intraoperative arteriography can be used after arterial thromboembolectomy as a guide for extension of the procedure. It is still a matter of debate whether intraoperative angiography should be routinely performed in all cases or only in selected cases, depending on intraoperative findings, when the surgeon suspects an incomplete disobstruction.
