Over the past 20 years the availability of aortic stent-grafts has allowed a major step change in the management of abdominal aortic aneurysms (AAA). Prior to this open surgical resection, first described by Charles Dubost in 1950, was the mainstay of AAA management. For elective cases open surgical repair has now largely been superseded by the deployment of a covered stent (stent-graft) through minimal surgical access in the common femoral arteries. Over the past few years there have been significant developments in stent-graft technology and an improved understanding of how best to utilise stent-grafts when treating aortic disease. Despite this, their role in the management of a patient with an AAA is still, at times, debatable.
Pre-procedureel
Type I: Inadequate seal (Ia: proximal, Ib: distal)
Type II: Retrograde flow from side branches of an aortic aneurysm (IIa: single vessel, IIb: two vessels or more)
Type III: Inadequate joint between the stent-grafts or damage to the stent-graft (IIIa: junctional separation of the modular components, IIIb: fractures or holes involving the endograft)
Type IV: Porosity of the stent-graft
Type V: Endotension; gradual enlargement without apparent endoleaks

Endoleaks
TLA Technique:
Embolization of the sac versus sac and branches shows no difference in outcomes.

Laser-Assisted Transgraft Embolization
Successful embolization was achieved with aneurysmal sac regression demonstrated on 1-year follow-up CT angiography.
Martini Pre-EVAR Embolization Criteria:
Pre-Discharge and Follow-Up Plan
TOP. AB profylaxe. Huiddesinfectie en steriel afdekken. Locale anesthesie met levobupivacaine 0,5% en lidocaine 1%. Beiderzijds echogeleide punctie AFC, meten voor Manta device, plaatsen 7Fr sheaths. 5000E heparine.
Via rechts inbrengen 260 cm Lunderquist via terumo/pigtail waarna inbrengen main body (ESBF-32-14-103). Via links inbrengen angiocatheter. Angiogram en aftekenen nierarteriën. Ontplooien mainbody tot en met contralaterale pootje, controle angiogram, ontplooien top-cap. Aanhaken contralaterale poot vanuit links, controle positie in de endograft door de pigtail te roteren. Inbrengen 260 cm Lunderquist via terumo/pigtail . Blow-back angiogram links en aftekenen AII. Inbrengen contralaterale poot (ETLW-16-16-156), ontplooien waarbij we landen in de AIC net boven de origo AII. Verwijderen delivery device en plaatsen 12Fr sheath.
Verder ontplooien main body tot en met de ipsilaterale poot, ophalen topcap en verwijderen delivery device. Inbrengen 16Fr sheath. Blowback angiogram en aftekenen AII rechts. Inbrengen en ontplooien ipsilaterale poot (ETLW-16-16-156) tot in de AIC net boven de origo AII. Naballoneren.
Controle angiogram: fraaie positie endograft, geen endoleak. Nierarteriën en AII bdz doorgankelijk.
Hemostase met Manta device bdz. SOP.
