Descending thoracic aortic diseases: stent-graft repair

PURPOSE: To evaluate endovascular treatment of descending thoracic aorta with commercially available self-expanding stent-grafts. MATERIALS AND METHODS: Seventy patients with aortic dissection, intramural hemorrhage, degenerative and posttraumatic aneurysm, penetrating atherosclerotic ulcer, and pseudoaneurysm underwent endovascular treatment. Eleven patients had impending rupture and were treated on an emergency basis. Stent-grafts were customized or selected on the basis of spiral computed tomographic (CT) or magnetic resonance (MR) imaging measurements. Preprocedure diagnostic angiography was performed in patients with aortic dissection and in other selected patients. All procedures were performed in an operating room and monitored with digital subtraction angiography (DSA) and transesophageal echocardiography (TEE). Follow-up was at 1, 3, 6, and 12 months after treatment and yearly thereafter. RESULTS: Stent positioning was technically successful in 68 cases. At DSA and TEE, complete aneurysm or false-lumen exclusion was achieved in 66 (97%) cases. No intraoperative mortality or complications occurred. In-hospital complications included transient monoparesis (one patient) and extension of dissection into ascending aorta (one patient) that was repaired surgically. Early endoleak was observed in five (7%) patients: In three (type 2), endoleak resolved spontaneously; in one (type 1), it was persistent; and in one (type 1), treatment was converted to surgery. At long term, one (1%) patient died of aortic rupture; another, of respiratory insufficiency. Five (7%) late endoleak (type 1, one caused by migration of the stent) cases were observed. In three (4%), endovascular treatment was successful; in two (3%), surgery was performed. In one patient with persistent postimplantation syndrome, treatment was converted to surgery after successful aneurysm sealing. Procedure failure (ie, aortic disease-related mortality or conversion to surgery) occurred in six (9%) patients. CONCLUSION: Endovascular stent-graft repair is less invasive in patients with chronic and acute descending thoracic aortic aneurysm and dissection.     

JAG Tearing Technique with Radiofrequency Guide Wire for Aortic Fenestration in Thoracic Endovascular Aneurysm Repair

An innovative approach, the JAG tearing technique, was performed during thoracic endovascular aneurysm repair in a patient with previous surgical replacement of the ascending aorta with a residual uncomplicated type B aortic dissection who developed an aneurysm of the descending thoracic aorta with its lumen divided in two parts by an intimal flap. The proximal landing zone was suitable to place a thoracic stent graft. The distal landing zone was created by cutting the intimal flap in the distal third of the descending thoracic aorta with a radiofrequency guide wire and intravascular ultrasound catheter.     

Emergency Endovascular Treatment of Sac Rupture for Type IIIa Endoleak in Thoracic Aortic Aneurysm Previously Excluded with Endovascular Repair

Elective endovascular treatment of thoracic aortic pathology has been applied in a variety of conditions. The complications of thoracic aortic stenting are also well recognized. Endoleak after endovascular repair of thoracic aortic aneurysms is the most frequent complication; among them, type III is the least frequent. Endovascular treatment of type III endoleak is generally performed under elective conditions; less frequently, in emergency. We report a successful emergency endovascular management of post-thoracic endovascular repair for thoracic aortic aneurysm rupture due to type IIIa endoleak.     

Endovascular Repair of Localized Pathological Lesions of the Descending Thoracic Aorta: Midterm Results

The endoluminal stent-graft represents an attractive and a less invasive technique for treatment of various diseases of the descending thoracic aorta. The purpose of this study was to evaluate the Talent endovascular stent-graft for the treatment of various localized diseases of the descending thoracic aorta. Over a 3-year period, Talent thoracic endografts were placed in 40 patients with a high surgical risk, presenting a localized lesion of the descending thoracic aorta: degenerative aneurysm (n = 13), acute traumatic rupture (n = 11), acute Stanford type B aortic dissection (n = 6), false aneurysm (n = 7), and penetrating atherosclerotic ulcer (n = 3). Fifteen patients (37.5%) were treated as emergencies. The feasibility of endovascular treatment and sizing of the aorta and stent-grafts were determined preoperatively by magnetic resonance angiography (MRA) and intraoperative angiography. Immediate and mid-term technical and clinical success was assessed by clinical and MRA follow-up. Endovascular treatment was completed successfully in all 40 patients, with no conversion to open repair or intraoperative mortality. The mean operative time was 37.5 ± 7 min. The overall 30-day mortality rate was 10% (n = 4), all in emergency cases, for causes not related to the endograft. The primary technical success was 92.5%. The mean follow-up period was 15 ± 5 months. The survival rate was 95% (n = 35). Diminution of the aneurismal size was observed in 47.5% (n = 19). We conclude that endovascular treatment of the various localized diseases of the descending thoracic aorta is a promising, feasible, alternative technique to open surgery in well-selected patients.
