ANSWERS AND EXPLANATIONS

---

A) Its annual incidence in the States is 6 per 100 000 populations/year

This answer is incorrect.

Ruptured Berry's aneurysm is responsible for up to 75% of cases of non-traumatic SAH. It has an equal sex incidence in general. Ruptured AVMs are mainly seen in the 2nd to 4th decades of life. Acute elevation of blood pressure (e.g. at orgasm) may be responsible for aneurysmal "rupture," not development. Ruptured AVMs are responsible for only 10% of SAH cases (with somewhat male preponderance).   (See References)

B) Cerebral AVMs are a very common cause of SAH world-wide

This answer is correct.

Ruptured cerebral Berry aneurysm is responsible for up to 75% of cases of non-traumatic SAH; it has an equal sex incidence in general. Ruptured AVMs are mainly seen in the 2nd to 4th decades of life. Acute elevation of blood pressure (e.g. at orgasm) may be responsible for aneurysmal "rupture," not development. Ruptured AVMs are responsible for only 10% of SAH cases (with somewhat male preponderance).  (See References)
