Is physical activity a trigger factor for subarachnoid hemorrhage?
2022, NeurochirurgieCitation Excerpt :Subarachnoid hemorrhage (SAH) is a serious disease associated to a 43% of mortality [1] and a capability to go back to previous professional activity in only a third of survivors [2]. Defecation and sexual activity account for 5.3 to 14% of the circumstances in which SAH occurs [3–5]. Venous hypertension due to Valsalva maneuvers is a suggested mechanism for the sudden variation of pressure gradient between intrasaccular and cisternal space responsible for aneurysmal rupture [6,7].
Repeated Retching and Vomiting in the Pathophysiology of Isolated Spinal Aneurysms
2021, World NeurosurgeryCitation Excerpt :Although our series is the first to attribute retching and vomiting to be involved in the formation and rupture of ISAs, data available in the literature support this hypothesis and clearly suggest that this phenomenon is more than a mere coincidence. Multiple studies have already demonstrated how hemodynamic changes increase the risk of SAH as seen in intense physical exertion,40,41 emotional stress,42 sexual activity,43,44 and physical maneuvers that increase intrathoracic pressure. Valsalva maneuver during defecation, micturition,45,46 and forceful sneezing47 have been attributed to causing SAH.
Clinical presentation of cerebral aneurysms
2013, European Journal of RadiologyCitation Excerpt :Ruptured intracranial aneurysms (RIAs), on the other hand, are by far the most common cause of SAH (85%) [4] with half of patients being younger than 55 [5], and represent a neurological emergency with potentially devastating consequences. In recent study cohorts, case-fatality rates within the first months, although declined in the last decades, are still reported to be as high as 35–39% [3,6,7], and sudden death is reported to occur in about 10% [8]. We will describe the clinical spectrum of unruptured and ruptured intracranial aneurysms by discussing both typical and uncommon clinical features emerging from the literature review.
