Chimney and periscope grafts to facilitate endovascular treatment of aortic transection in a patient with aberrant right subclavian artery

2014

Purpose: To report the use of parallel grafts to extend the proximal landing zone for stentgraft repair of aortic transection involving an aberrant right subclavian artery (ARSA). Case Report: A 28-year-old patient was referred for treatment of traumatic aortic transection with contained rupture at the level of an ARSA. Immediate thoracic endovascular aortic repair (TEVAR) was planned because of hemodynamic instability. To achieve rapid sealing and maintain perfusion to both subclavian arteries, a chimney stent to the left subclavian artery (LSA) and a periscope stent-graft to the ARSA were deployed successfully. After surgical repair of all fractures, the patient was discharged 1 month aft…

Percutaneous angioplasty and stenting of left subclavian artery lesions for the treatment of patients with concomitant vertebral and coronary subclav…

2006

bjective: To evaluate the efficacy of subclavian stenosis percutaneous transfemoral angioplasty (PTA)-treatment in patients with intermittent or complete subclavian steal syndrome (SSS), and coronary-subclavian steal syndrome (C-SSS) after left internal mammary artery-interventricular anterior artery (LIMA-IVA) by pass graft. Methods: We studied 42 patients with coronary subclavian steal syndrome subdivided in two groups; the first group consisted of 15 patients who presented an intermittent vertebral-subclavian steal, while the second group consisted of 27 patients with a complete vertebral-subclavian steal. All patients were treated with angioplasty and stent application and were followed…

Should intentional endovascular stent-graft coverage of the left subclavian artery be preceded by prophylactic revascularisation?

2011

Thoracic endovascular aortic repair (TEVAR) has emerged as a promising therapeutic alternative to conventional open aortic replacement but it requires suitable proximal and distal landing zones for stent-graft anchoring. Many aortic pathologies affect in the immediate proximity of the left subclavian artery (LSA) limiting the proximal landing zone site without proximal vessel coverage. In patients in whom the distance between the LSA and aortic lesion is too short, extension of the landing zone can be obtained by covering the LSA's origin with the endovascular stent graft (ESG). This manoeuvre has the potential for immediate and delayed neurological and vascular symptoms. Some authors, ther…

TEVAR and periscope graft technique to treatment of huge aneurysm of aortic isthmus: Case report

2021

Introduction Thoracic endovascular aortic repair (TEVAR) has revolutionized the treatment of thoracic aortic aneurysms. Innovative techniques as chimney and periscope grafts can improve the outcomes of procedure. Herein, we report a case in emergency of huge Thoracic aortic aneurism. Presentation of case An 86-year-old male with hypertension, diabetes mellitus, was referred to our hospital for chest pain. CT-angiography showed a huge aneurysm of aortic isthmus with signs of rupture. The patient was considered unfit for open surgery and an endovascular approach was chosen. This patient underwent endovascular repair with TEVAR, using the periscope graft technique to preserve patency in left s…

Periscope endograft technique to revascularize the left subclavian artery during thoracic endovascular aortic repair.

2013

Purpose: To present early and midterm results of the periscope endograft (PG) technique to maintain left subclavian artery (LSA) blood flow in thoracic endovascular aortic repairs (TEVAR) involving zone 3. Methods: From April 2010 to January 2013, 14 consecutive high-risk patients (11 men; mean age 7068 years, range 56–87) underwent TEVAR with the PG technique for 10 thoracic aortic aneurysms (TAA), 2 traumatic aortic ruptures, and 2 aortic dissections without a suitable landing zone (.2 cm distal to the LSA). Five procedures were performed emergently for rupture (3 TAAs and the 2 trauma cases). Two patients had a periscope deployed in an aberrant right subclavian artery. The periscope endo…
