Aims and objectives
Endoleaks which are defined as a persistent blood flow within the aneurysm sac [1],
constitute a common complication after endovascular abdominal aortic aneurysm repair (EVAR) [2].
Can be classified into five types according to the origin [3].
There are several options for their treatment including transarterial approach or direct puncture,
regarding type of endoleak [3].
SquidPeri (Emboflu,
Switzerland) is a liquid embolic agent,
used for peripheral vascular intervention,
originally designed and intended for use in the cerebral vasculature [4].
The purpose of the study is...
Methods and materials
10 patients (mean age: 72.7 years)underwent 11 endovascular procedures - either translumbar embolization (n=4) or transarterial embolization (n=7) between January 2014 and September 2017.
Indications for the procedure included type 2 endoleak with an aneurysm sack enlargementand endoleak type 1,
which was impossible to treat with cuff extension.
Success of the embolization was defined as a total occlusion of the endoleak zone in angiography and absence of recanalization and aneurysm enlargement in 6-month follow-up CT.
Results
Initial endoleak repair was successful in 9 patients.
Transarterial approach was not successful in one patient and the case required a second attempt with translumbar approach. Neither persisting endoleak,
nor aneurysm sac enlargementwere observed in any of treated patients in 6-month follow-up examination.
Conclusion
Squid plays an important role in the treatment of intracranial arteriovenous lesions and seems to be an effective treatment method for endoleak cases (SquidPeri).
This embolic material can be characterized by low risk of complication rate,
low probability of recurrence and permanent embolization results.
