Anamnesi
• Uomo, 59 anni
• Ex fumatore, iperlipemia mista
• Iperteso, importante cardiopatico
1987 IMA con residua acinesia ant. ventricolo sin
1990 Triplice bypass aorto-coronarico, aneurismectomia
ventricolo sin, Coumadin, Lanoxin, Adalat
1995 Colecistectomia laparotomica
Febbraio 2000 diagnosi di AAA Ø 6 cm,
trattam. endovascolare
in altra sede: “Vanguard” retta
ictus minor p.o.
endoleak tipo I all’ angiotac p.o.
Agosto 2000 re-trattamento endovascolare con
protesi “Excluder” biforcata
Febbraio 2001 controllo angiotac: regolare esclusione
aneurismatica
3 luglio 2001ore 18.40’ RICOVERO D’URGENZA IN ALTRA

INCIDENCE AND RISK FACTORS OF LATE RUPTURE ,
CONVERSION AND DEATH AFTER ENDOVASCULAR
REPAIR OF AAA : THE EUROSTAR EXPERIENCE
Harris PL, J Vasc. Surg, Oct 2000
• 2.464 pts , mean follow up 12,19 months
• Cumulative risk of rupture 1% per year
• Significant risk factors for rupture: proximal type
I and III leaks, graft migration and kinking
• Cumulative risk of late conversion 2,1% per year
• Global risk of failure 3% per year
RUPTURED ABDOMINAL AORTIC ANEURYSM
AFTER ENDOVASCULAR REPAIR
Bernhard VM, J Vasc. Surg, Juin 2002
• 5/686 EVT first generation, mean follow-up 42 mths
• 2/3260 EVT market approved, specifically in the
subgroup of 166 tube grafts (37,5 months)
• overall mortality 4/7 (57%) and surgical
mortality 3/6 (50%)
• LITERATURE SEARCH : 40 additional ruptures of
other devices, mainly due to type I and III leak, with
an overal mortality 50% and operative mortality 41%
• CONCLUSION: outcome of postendograft rupture is
similar to rupture without prior endograft therapy
Complications in endovascular repair of abdominal aortic
aneurysms: treatment and prevention.
2011
re-intervention rate 10.4% (29/279)
overall complication rate 12.9% (36/279)
including endoleak 5.7% (16/279)
stent-graft migration 1.1% (3/279)
aneurysm expansion or rupture 5.4% (15/279)
limb occlusion 2.5% (7/279)
stent-graft infection 1.4% (4/279)
Chronic contained abdominal aortic aneurysm
rupture after suprarenal fixation fatigue fracture
• 20 days before his admission to our hospital, he had undergone a
secondary iliac limb extension for treatment of post-EVAR rupture.
• On admission, abdominal plain radiography identified suprarenal
fixation fracture as a possible reason for CCR, but computed
tomographic angiography failed to confirm any endoleak or "active"
bleeding and rupture.
• The patient received medication treatment for possible diverticulitis
and was kept under close monitoring for suspected failure of recently
performed secondary endovascular procedure and CCR
.

Chronic contained abdominal aortic aneurysm
rupture after suprarenal fixation fatigue fracture
A day later, the abdominal pain symptoms
worsened, and a new computed
tomographic angiography confirmed the
suspected CCR. The patient was treated
successfully by "open" repair using a Y
prosthesis

Lifelong post-EVAR follow-up with high
level of both clinical and imaging
diagnostic accuracy is essential for the early
recognition and proper treatment of EVAR
pitfalls.

Conclusione
Possibile effetto tamponamento parziale
dell’endoprotesi
