Conditions associated with aneurysms

1. autosomal dominant polycystic kidney disease:

2. fibromuscular dysplasia (FMD): prevalence of aneurysms in renal FMD is 7%, in aortocranial FMD 21%

3. arteriovenous malformations (AVM) including moyamoya disease

a) Ehlers-Danlos, especially type IV (deficient collagen type III)which also has a high rate of arterial dissection, including with angiography or coiling

b) Marfan syndrome

c) pseudoxanthoma elasticum

5. multiple other family members with intracranial aneurysms. Familial intracranial aneurysm syndrome (FIA): 2 or more relatives, third-degree or closer, harbor radiographically proven intracranial aneurysms.

6. coarctation of the aorta ¹⁾

7. hereditary hemorrhagic telangiectasia ²⁾ (Osler-Weber-Rendu syndrome)

8. atherosclerosis ³⁾.

9. bacterial endocarditis

10. multiple endocrine neoplasia type 1 ⁴⁾.

11. neurofibromatosis type 1 ⁵⁾.

Aneurysms associated with arteriovenous malformations (AVM) are well represented in the literature. Their exact etiology is poorly understood, but likely global hemodynamic changes coupled with vascular wall pathology play into their formation. Flow-related and intranidal aneurysms, in particular, appear to have an increased risk for hemorrhagic presentation. Treatment strategies for these aneurysms are particularly challenging ⁶⁾.
