Mid-term results of zone 0 thoracic endovascular aneurysm repair after ascending aorta wrapping and supra-aortic debranching in high-risk patients

Objectives Surgical repair of aneurysmal disease involving the ascending aorta, aortic arch and eventually the descending aorta is generally associated with significant morbidity and mortality. A less invasive approach with the ascending wrapping technique (WT), supra-aortic vessel debranching (SADB) and thoracic endovascular aneurysm repair (TEVAR) in zone 0 was developed to reduce the associated risk in these patients. Methods During a 10-year period, consecutive patients treated by the ascending WT, SADB and TEVAR in zone 0 were included. All patients were considered at high risk for conventional surgery. Measured outcomes included perioperative deaths and morbidity, maximal aortic trans…

A New Off-Pump Hybrid Open and Endovascular Repair to Treat Ductus Botalli and Ascendens Aneurysms

To report a combined ascending aorta and aortic arch hybrid repair, we performed off-pump with no aortic graft replacement. A 65-year-old man, developing progressive recurrent laryngeal nerve paralysis, underwent a computed tomography (CT) angiography detecting nonpatent residual ductus Botalli aneurysm and ascending aorta aneurysm. Due to severe multimorbidities, a less-invasive alternative was elaborated. In a first step, appropriate proximal landing zone for aortic stent grafting was achieved by ascending aorta diameter reduction, with epiaortic wrapping, and debranching the supra-aortic trunks. In the second step, endovascular stent grafts were deployed from proximal ascending aorta to…

Classification of Chimney EVAR-Related Endoleaks: Insights from the PERICLES Registry

Juxtarenal aortic aneurysms (JAAs) pose significant challenges for endovascular aneurysm repair (EVAR). A short or absent infrarenal neck typically excludes standard EVAR as a viable or reasonable treatment option. In this context, the use of chimney grafts (chEVAR) is gaining in popularity and applicability. These grafts are designed to course in the aortic lumen outside the main stent-graft to maintain normal perfusion to the involved target branches. As such, they may represent a promising and less resource-intensive option for management of JAAs. However, this technical strategy is not without challenges of its own, particularly the inevitable creation of “gutters” that result from the …

Hypotensive Hemostasis in Patients Presenting with Ruptured Aortic Aneurysm

Hypotensive hemostasis in aortic rupture has been showed to be feasible and advantageous, especially in trauma patients. To date, there are no randomized studies on hypotensive hemostasis in patients with ruptured abdominal aortic aneurysm (rAAA), but observational studies indicate similar advantages when hypotensive hemostasis is used for endovascular aneurysm repair (EVAR) as in trauma patients. Actually, in EVAR for rAAA, a target systolic blood pressure of 90 mmHg or even lower is considered safe in conscious patients. Fluids should be administrated judiciously with the sole aim of maintaining adequate cardiac output and tissue oxygenation, whereas vasoactive pressors or dilatators may …
