ARAMBURU, Ignacio; JAUME, Alejandra; ROMERO, Mariana  and  SPAGNUOLO, Edgardo. Aneurysm “de novo” Case report and literature review. Rev. Urug. Med. Int. [online]. 2016, vol.1, n.3, pp.84-91. ISSN 2393-6797.

ABSTRACT Introduction: An aneurysm is defined as “de novo”, when it appears in a repeated angiography and not seen in a previous study, being a fundamental requirement that vascular studies the patients are of good quality. Most of the published works are for patients who suffered a subarachnoid hemorrhage due to rupture of a new aneurysm. Although their frequency is very low, in certain (young, hypertension, smoking, multiple aneurysms) patients, angiographic follow-up for a long period of time is suggested. Making the diagnosis of these aneurysms before they rupture, substantially improve the prognosis. Materials and Methods: A case who presented a complicated subarachnoid hemorrhage with acute subdural hematoma due to rupture of an aneurysm, which by definition turned out to be “de novo” is presented. An update on this pathology was performed. Discussion: The incidence of occurrence of “de novo” aneurysms hovers around 1%, and the interval between the first angiographic study and the manifestation of it is variable, on average 10 years. Its presence increases the risk of subarachnoid hemorrhage up to 6 times. There are several risk factors that increase the probability of these aneurysms, which take them into account, they allow us to properly track and in many cases get a timely diagnosis. Conclusions: Although “de novo” aneurysms have a low incidence, patients with subarachnoid hemorrhage, especially young women, should have angiographic follow-up of no less than 10 years. The detection of these aneurysms before they cause an subarachnoid hemorrhage, substantially improves prognosis, since morbidity and mortality is much lower with the treatment of unruptured aneurysms.
