Overall,
10 of 33 patients underwent endovascular treatment encompassing spiral embolization (n=9) or covered stentgraft placement (n=1) for aneurysms of the celiac trunk (n=1),
hepatic (n=4),
splenic (n=4),
or gastroduodenal artery (n=1).
Mean aneurysm diameter was 30 +/- 15 mm in interventionally treated patients.
Aneurysms which were only followed by surveillance had a mean diameter of 10 +/- 5 mm.
Initial technical success rate of endovascular therapy was 100%.
The mean follow-up period was 38 months (range 3-108 months).
After splenic artery embolization postembolization-syndrome occurred in 2 patients.
No further endovascular procedure-related complications occurred.
Untreated aneurysms showed no increase in size over time.
Consequently,
no re-intervention or surgical intervention was necessary.
Figure 6 depicts a large aneurysm of the splenic artery with a diameter of about 3 cm.
Figure 7 shows the corresponding selective DSA with a micro-catheter.
After successful interventional embolization therapy with platinum coils selective DSA (Figure 8) confirms a sufficient occlusion of the "front-" and "back-door" as well as some coils within the aneurym itself.
The postinterventional CT scan (Figure 9) reveals a segmental infarction of the spleen due to the embolization.
Figure 10 displays the selective DSA of a pedunculated aneurysm of the hepatic artery,
which was also correlated with duplex-ultrasound (Figure 11).
After successful embolization therapy,
selective DSA confirms a complete occlusion of the aneurysm sac with a patent hepatic artery (Figure 12).
Figure 13 shows the CTA of a rare case of an enormous true aneurysm of the anterior pancreaticoduodenal artery.
The selective DSA (Figure 14) depicts two consecutive aneurysm sacs.
Note,
there is a retrograde flow to the gastroduodenal and common hepatic artery due to an occlusion of the superior mesenteric artery (not shown).
The selective DSA after successful embolization therapy (Figure 15) depicts an occlusion of the treated aneurysms and a patent flow to the hepatic artery via the dorsal pancreaticoduodenal artery.
