Transposition of the Left Carotid Artery to the Ascending Aorta to Repair Aortic Arch Injury

JOURNAL OF CARDIAC SURGERY, Issue 1 2009
Salvatore Lentini M.D.
A 52-year-old man presented to our department with a penetrating chest wound by a gunshot in the attempt of suicide. The aortic arch and the insertion of the left carotid artery were involved in the lesion. Through sternotomic approach, the aortic arch was repaired in extracorporeal circulation. Left carotid artery was transected to allow easier repair of the arch posterior wall involved in the lesion, and to reduce the danger of residual stenosis. Then, it was translocated to the ascending aorta by interposing a 7-mm Gore-Tex (W.L. Gore & Associates, Flagstaff, AZ, USA) conduit. The patient complicated renal failure and pneumonia in the postoperative period, but eventually he was discharged in good general conditions. [source]

Carotid artery stenting: Do procedural complications relate to the side intervened upon?,

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 1 2009
Registry of the Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte (ALKK), Results From the Carotid Artery Stent (CAS)
Abstract Objectives: To determine the influence of the side intervened upon on outcomes during carotid artery stenting (CAS). Background: Anatomic and technical aspects may influence the results of CAS. The value of the side intervened upon has not been analyzed yet. Methods: We analyzed data from the Carotid Artery Stent (CAS) , Registry.Results: A total of 3,165 CAS procedures, 1,613 (51%) at the left and 1,552 (49%) at the right carotid artery were included. There was a higher proportion of patients treated for symptomatic stenoses when CAS was performed at the left carotid artery (50.1% versus 45.8%, P = 0.016) and more patients already had prior carotid endarterectomy (8.5% versus 5.8%, P = 0.003). Interventions at the left side took 3 min longer than interventions at the right side (46.6 ± 24.3 versus 43.8 ± 23.6, P = 0.003). In patients treated at the left carotid artery amaurosis fugax (0.7% versus 0.1%, P = 0.005), ipsilateral stroke (3.1% versus 1.8%, P = 0.017), and the primary endpoint of in-hospital death or stroke (4.1% versus 2.3%, P = 0.005) occurred significantly more often. Even after adjusting for confounding parameters, CAS procedures performed at the left carotid arteries remained an independent predictor of death or stroke (OR = 1.77, 95% CI: 1.15,2.72, P = 0.009). Conclusions: In current clinical practice, CAS is performed frequently at the right carotid artery as at the left carotid artery. CAS interventions have a higher in-hospital complication rate if performed at the left carotid artery. Technical improvements might help to overcome this situation. © 2009 Wiley-Liss, Inc. [source]

A Novel Subcutaneous Counterpulsation Device: Acute Hemodynamic Efficacy During Pharmacologically Induced Hypertension, Hypotension, and Heart Failure

ARTIFICIAL ORGANS, Issue 7 2010
Carlo R. Bartoli
Abstract The miniaturization of mechanical assist devices and less invasive implantation techniques may lead to earlier intervention in patients with heart failure. As such, we evaluated the effectiveness of a novel, minimally invasive, implantable counterpulsation device (CPD) in augmenting cardiac function during impaired hemodynamics. We compared the efficacy of a 32-mL stroke volume CPD with a standard 40-mL intra-aortic balloon pump (IABP) over a range of clinically relevant pathophysiological conditions. Male calves were instrumented via thoracotomy, the CPD was anastomosed to the left carotid artery, and the IABP was positioned in the descending aorta. Hemodynamic conditions of hypertension, hypotension, and heart failure were pharmacologically simulated and data were recorded during CPD and IABP support (off, 1:2, 1:1 modes) for each condition. In all three pathophysiological conditions, the CPD and IABP produced similar and statistically significant (P < 0.05) increases in coronary artery blood flow normalized to the left ventricular (LV) workload. During hypotension and heart failure conditions, however, the CPD produced significantly greater reductions in LV workload and myocardial oxygen consumption as compared with the IABP. A novel 32-mL CPD connected to a peripheral artery produced equivalent or greater hemodynamic benefits than a standard 40-mL IABP during pharmacologically induced hypertension, hypotension, and heart failure conditions.
