Sutureless Clampless Telescoping Method for Aortic and Arterial Anastomoses Using an Endograft Connector
Full text linkTips and tricks to make the ascending aorta accessible to EVAR
No full textThe ascending aorta is gaining increasing interest for endovascular specialists, as it opens the
door to a potentially better way to treat aortic arch pathologies. Landing safely a stentgraft into the
ascending aorta allows downgrading significantly the invasiveness of conventional open repair of the
ascending aorta and/or aortic arch. Unfortunately, accessibility to the ascending aorta, in order to perform
EVAR, can be challenging as the transfemoral approach might be cumbersome, or because the
ascending aorta might not be appropriate for stentgraft landing. This paper will present some technical
tips and tricks to achieve successful stentgraft landing in zone 0
Endoluminal stent-graft relining of visceral artery bypass grafts to treat perigraft seroma.
No full textPurpose: To describe the endovascular treatment of intra-abdominal perigraft seromas
associated with small-caliber expanded polytetrafluoroethylene (ePTFE) grafts.
Case Reports: Two patients who underwent hybrid repair of thoracoabdominal aortic
aneurysms in which renovisceral bypass grafts were implanted presented with large,
symptomatic perigraft seromas. The 5- to 8-mm-diameter ePTFE bypass grafts believed to
be involved in the seromas were successfully relined with self-expanding Viabahn stentgrafts
in percutaneous procedures. The patients’ symptoms were relieved, and imaging
follow-up (18 and 10 months, respectively) has shown near complete resorption of the
seromas.
Conclusion: It is expected that this minimally invasive technique could be very valuable in
treating aortic, renovisceral, and peripheral perigraft seroma
How to diagnose and treat abdominal compartment syndrome after endovascular and open repair of ruptured abdominal aortic aneurysms
No full textIntra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are frequently encountered in patients treated for ruptured abdominal aortic aneurysms (rAAA) and carry a high morbidity and mortality risk. Despite these facts, IAH/ACS are still overlooked by many physicians, timely diagnosis is missed and treatment often inadequate. All staff involved in the treatment of rAAA should be aware of the risk factors predicting IAH/ACS, the profound implications and derangements on all organ systems, the clinical presentation, the appropriate measurement of intra-abdominal pressure to detect IAH/ACS and the current treatment options for these detrimental syndromes. This comprehensive review provides contemporary knowledge that should help to improve patient survival and long-term outcome

Complete Renovisceral Debranching and EVAR for thoracoabdominal aort aneurysm
Full text linkOpen graft repair of thoracoabdominal aortic aneurysms (TAAA) is an incredibly complex and
challenging procedure with acceptable results achieved only by a few centers worldwide.
Contemporary outcome analysis of TAAA repair performed in the United States showed greater operative
mortality and morbidity rates than commonly reported. Moreover, a recent European long-term
follow-up study showed that survival remains suboptimal, especially in the early years after TAAA
repair. Complete renovisceral debranching combined with EVAR offers many advantages in regard
to open surgical repair with comparable or better results, especially in the high-risk patient. Although
this hybrid procedure will not replace open surgical repair, the latter will significantly decrease during
the next decades, as very experienced surgeons will be lacking, due to the mainly endovascular
generation of surgeons being educated nowadays. Similarly, the results of the hybrid TAAA repair
will improve, as new techniques will eliminate most barriers still existing today
Use of the STAT (Sutureless Telescoping Anastomosis Technique) to facilitate supraaortic revascularization: Mid-term Results
Full text linkChimney and periscope grafts to facilitate endovascular treatment of aortic transection in a patient with aberrant right subclavian artery
Full text linkPURPOSE: To report the use of parallel grafts to extend the proximal landing zone for stent-graft 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 after the initial injury in good condition. Imaging follow-up at 10 months showed a stable repair, patent parallel grafts, and no complications.
CONCLUSION: TEVAR with chimney and periscope grafts proved to be a safe and quick treatment for a patient requiring ARSA repair in acute aortic transection. This technique maintained blood flow to the ARSA and LSA in a totally endovascular approach, which could be very valuable in transection cases where bypass surgery to supra-aortic branches is compromised or deemed challenging due to thoracic wall and/or neck trauma. Parallel grafting can be a valuable tool to address any acute aortic pathology as it can be performed with off-the-shelf devices
