Awareness

The CLI Global Society

Dr. Fadi Saab presents the background, the structure and the activities of the CLI Global Society. The lack of awareness within the healthcare community and the general public remains the biggest challenge in CLI treatment. In 2017, primary amputation was still the first-line treatment and the costs of the disease were among the greatest healthcare expenditures. In this regard, the CLI Global Society has the mission to change this and to reduce both amputation and mortality rate in this cohort.

Endovascular treatment of recurrent acute deep vein thrombosis

Prof. Bisdas (Vascular Surgery, Athens, Greece) presents a recorded case of a recurrent DVT in the right common iliac vein treated by percutaneous thrombectomy and venous stenting. In this case, the operator discusses important issues like decision making, criteria for selecting the thrombectomy device and the stent, how to choose the right diameter for your stent, crucial steps during the intervention and which should be the duration and type of anticoagulation after endovascular treatment.

Review of the literature

Decision-making in intermediate femoropopliteal lesions

Professor Katsanos (Interventional Radiology, Patras, Greece) provides an evidence-based overview of different techniques and devices for the treatment of intermediate (<15cm) femoropopliteal lesions. Which should be your first treatment strategy? Which is the role of drug-eluting stents? Do we have enough evidence about atherectomy? What is vessel prep and how important is for the durability of the treatment strategy? Is there still space for the use of stent-grafts in the SFA?

Thoracoabdominal aortic aneurysm: when to treat open and when endo?

Professor Dr. Böckler (Vascular Surgeon, Heidelberg, Germany) provides an overview of the current evidence regarding decision making in the treatment of TAAA. Which patients' characteristics should influence your decision, do we have head-to-head comparisons between open surgery and endo-repair, what about the risk of spinal cord ischemia, and many other relevant questions will be answered in this presentation and discussed between the panelists.

Technical note

Removing stent grafts and implications for putting them in

"Who will do my aortic surgery when my time comes" was a common refrain among my mentors, only half jokingly. Now, the question has gained a sharpness. I think the tide will turn and the kids will do fine, but we all have to do a bit of reclamation, or open surgery will become the habit of strange eccentric artisans. I recommend calling up the retired surgeon and inviting them in for conferences and cases. Reprint masterwork atlases like Wiley's. Connect with likeminded. Before it's too late.

Management of the false lumen in chronic aortic dissection

False lumen (FL) thrombosis and aortic remodeling is a major predictor of survival in chronic aortic dissection (AD). Chronic AD (> 3 months) is associated with a non-compliant intimal flap, multiple fenestrations in the intimal flap and aortic branch artery communication with the FL. This makes FL thrombosis and subsequent aortic remodeling difficult to achieve with conventional thoracic EVAR devices. This presentation provides an overview of different methods to manage FL in chronic AD.

Review of the literature

A brief history of surgical repair of the abdominal aortic aneurysm

Since India’s Sushruta (800-600 BC) first reported that "aneurysms can be cured only with the greatest difficulty", the majority of surgeons shared a fear of aortic surgery till the first half of the 20th century. The surgical treatment of AAA became available only in the second half of the 20th century. This presentation summarizes the most important historical milestones in AAA surgery.

Experimental investigation

In-vitro experimental investigation of different bridging stent-grafts for fEVAR

Giovanni Torsello (Vascular Surgeon, GER) presents and discusses with the experts the latest results from an experimental head-to-head investigation of different bridging stent-grafts (BSG) used in fenestrated aortic endografting.
How does the material respond to balloon dilatation? Which are the forces that might lead to the dislocation of the BSG from a fenestration? Endoleak of unknown origin after fEVAR: could be associated with material fatigue?

Case report

Periscope and Chimney-EVAR for a ruptured AAA following infrarenal EVAR

Despite the latest advances in both endovascular field and open repair, a ruptured AAA still remains one of the most challenging situations in vascular medicine. This case shows the use of chimney and periscope grafts for the treatment of a Type Ia Endoleak in patient presenting with a ruptured AAA.

Review of the literature

Paraplegia after endovascular TAAA-repair:

Why does the endovascular TAAA repair increase the risk of spinal cord ischemia (SCI)? Which are the challenges? How can you prevent SCI during complex endovascular TAAA repair? Do we have enough evidence for the prohylactic use of cerebrospinal fluid drainage in the endovascular treatment of complex TAAAs?

Recorded video case

Open surgical repair of a pararenal AAA

In this video case, we present our standard practice of open surgical repair for pararenal AAA. In general, we performed open repair with the “clamp and sew” technique, and the application of cold renal perfusion is limited to the cases with renal revascularization. Sometimes, division of left renal vein is imperative for better access to the suprarenal aorta. Retrospective analysis of our series revealed no negative impact of the division on long-term renal function - J Vasc Surg 2018;67:1042-1
