Extent Intravenous Thoracoabdominal Aortic Aneurysms: A Systematic Review

Abstract

after thrombolysis procedure. We analyzed the incidence of arterial emboli according to the method of thrombolysis and the location of the dialysis graft by Chi-square test. Results: Arterial emboli were documented by angiography in 83 cases (3.3%) of patients. Sixty-one cases of embolization involved the brachial artery or its branches, 14 involved the ulnar artery, and 8 involved the radial artery. Two patients complained of finger pain, but it immediately subsided. The numbers and incidence of arterial emboli according to the thrombolysis method are given. Arterial emboli were retrieved by occlusion balloon/fogarty balloon (45), guiding catheter-assisted aspiration (15), observation without intervention ( 16), sheath assisted aspiration (2), back-bleeding technique (3), and others (2). Subsequent fistulograms obtained in 26 patients and demonstrated arterial stenosis in 2 patients. Follow-up fistulogram demonstrated complete resolution of the observation emboli in three of four patients. Conclusion: Arterial emboli are seldom occurrence during percutaneous dialysis graft thrombectomy procedure, and the majority can be easily retrieved by percutaneous techniques. Clinical observation also appears to be indicated in asymptomatic patients.
