1/15. Pure acute subdural haematoma without subarachnoid haemorrhage caused by rupture of internal carotid artery aneurysm.A 52-year-old female presented with disturbance of consciousness and clinical signs of tentorial herniation. Computed tomography showed a pure acute subdural haematoma (SDH) over the left convexity without subarachnoid haemorrhage. cerebral angiography showed a saccular aneurysm at the junction of the left internal carotid artery and the posterior communicating artery. Surgery to remove the haematoma and clip the aneurysm showed the rupture point was located in the anterior petroclinoid fold (subdural space). The patient recovered without neurological deficits. Pure SDH caused by ruptured aneurysm is rare. rupture of an aneurysm adhered to either the dura or falx and located in the subdural space may cause pure SDH. Therefore, ruptured intracranial aneurysm should be considered as a cause of non-traumatic SDH. Immediate removal of the SDH and aneurysmal clipping is recommended in such patients, even those in poor neurological condition.- - - - - - - - - - ranking = 1keywords = subarachnoid haemorrhage, subarachnoid, haemorrhage (Clic here for more details about this article) |
2/15. Fatal subdural haemorrhage following lumbar spinal drainage during repair of thoraco-abdominal aneurysm.A 63-year-old male patient collapsed and died from a major subdural haemorrhage 5 days after elective repair of a Type III thoraco-abdominal aortic aneurysm. The anaesthetic technique had included the use of a lumbar cerebrospinal fluid drain. The management of the patient is described, and the association between subdural haemorrhage and cerebrospinal fluid drainage is discussed.- - - - - - - - - - ranking = 0.069252344742563keywords = haemorrhage (Clic here for more details about this article) |

4/15. Acute subdural hematoma in patients who underwent aneurysm clipping--four case reports.Four patients presented with intracranial hemorrhage mainly consisting of acute subdural hematoma (ASDH), who had all undergone aneurysm clipping 2-20 years earlier. Whether the clips had slipped or new trauma had caused the bleeding was difficult to determine, since the initial computed tomography showed that the subarachnoid hemorrhage or the intracerebral hematoma developed near the clips. Angiography in three patients showed that the clips had not slipped off. Three of four ASDHs appeared in the same side as the craniotomy used for the previous aneurysm surgery. Anti-platelet agents and ventriculoperitoneal shunting had been previously used in two patients with no causal signs of trauma. The outcomes were poor in three patients and one patient died. Weakening of the extra- or intracranial structure after aneurysm surgery might have been involved together with the postoperative anti-platelet agent and shunt treatment in the etiology of the present ASDH.- - - - - - - - - - ranking = 0.041762098240333keywords = subarachnoid (Clic here for more details about this article) |
5/15. Acute subdural hematoma caused by ruptured cerebral aneurysms: diagnostic and therapeutic pitfalls.On rare occasions, rupture of a cerebral aneurysm causes acute subdural hematoma (SDH) in addition to subarachnoid hemorrhage (SAH). The frequency of SDH resulting from aneurysmal rupture is summarized, and its clinical and radiological characteristics, as well as potential pitfalls in the diagnosis and the management of this life-threatening condition are described. Among 641 patients with nontraumatic SAH treated between 1992 and 2000, 12 patients (1.9%) presented with SDH due to aneurysmal rupture. The SAH grade on admission was grade II in one patient, grade IV in three patients, and grade V in eight patients. Four underwent both hematoma evacuation and clipping of the aneurysm, four underwent hematoma evacuation alone, and the other four patients were treated conservatively. The outcome was good recovery in two patients, severe disability in one patient, and death in nine patients. patients with a good outcome had a better SAH grade on admission, smaller midline shift, and smaller SDH volume on the initial CT scan, and they had been treated by both SDH evacuation and clipping of the aneurysm. Emergency one-stage operations may be beneficial for aneurysmal SDH patients who are in good SAH grade, or those who are in poor SAH grade but show some neurological recovery after resuscitation. It should also be mentioned that there are cases of aneurysmal SDH without recognizable SAH on the CT scans, and that a case of aneurysmal SDH may present as a case of 'head trauma' after an accident, because of the disturbance of consciousness resulting from aneurysmal rupture.- - - - - - - - - - ranking = 0.041762098240333keywords = subarachnoid (Clic here for more details about this article) |
6/15. Remote hypertensive intracerebral haematoma following clipping of an intracranial aneurysm.We report a case of a 58-year-old woman who presented with an aneurysmal subarachnoid haemorrhage. Immediately following clipping of this aneurysm, she had a spontaneous hypertensive bleed in the contralateral hemisphere. Although very unusual, hypertensive episodes following aneurysmal subarachnoid haemorrhage must carry a risk of such an intracranial event.- - - - - - - - - - ranking = 0.4keywords = subarachnoid haemorrhage, subarachnoid, haemorrhage (Clic here for more details about this article) |
7/15. Pseudosubarachnoid haemorrhage in subdural haematoma.Two patients with large bilateral subdural haematomas with patterns of non-enhanced brain computed tomography (CT) falsely suggesting coexistent subarachnoid haemorrhage are presented. The CT images showed marked effacement of the basal cisterns with hyperdense signal along the tentorium, sylvian fissure, and the perimesencephalic cisterns. In both cases, the suspicion of subarachnoid haemorrhage led to the performance of angiographic studies to rule out vascular lesions. Thus, recognition of this radiological feature is important to avoid unnecessary testing and treatment delay.- - - - - - - - - - ranking = 1.0533041556974keywords = subarachnoid haemorrhage, subarachnoid, haemorrhage (Clic here for more details about this article) |
8/15. Haemangiopericytoma presenting as acute subdural haematoma.Haemangiopericytomas are vascular neoplasms that arise from capillary pericytes. They rarely present with haemorrhage.

9/15. Acute subdural haematoma due to ruptured intracranial aneurysms.Acute spontaneous subdural haematoma (SDH) is rarely associated with rupture of intracranial saccular aneurysm. We report our experience with four cases of non-traumatic SDHs secondary to rupture of an intracranial aneurysm and discuss the diagnosis and management of this condition. We retrospectively reviewed of four cases of acute SDH due to cerebral aneurysm rupture confirmed by cerebral angiography and surgery. patients were evaluated using the glasgow coma scale (GCS) and subarachnoid grade of the World Federation of Neurosurgical societies (WFNS) and outcome with the glasgow outcome scale (GOS). Of the 232 patients with non-traumatic subarachnoid haemorrhage (SAH) treated between 1993 and 2002, only four patients (1.72%) presented SDH due to aneurysmal rupture. The SAH grade on admission was grade IV in one patient and V in the other three. In all cases the aneurysm was located in the posterior communicating artery. Spontaneous acute SDH secondary to aneurysm rupture has been rarely reported. We suggested that timely SDH removal and aneurysmal clipping surgery should be performed in such patients, including those in poor neurological condition.- - - - - - - - - - ranking = 0.24176209824033keywords = subarachnoid haemorrhage, subarachnoid, haemorrhage (Clic here for more details about this article) |
10/15. mutism after evacuation of acute subdural hematoma of the posterior fossa.CASE REPORT: A 7-year-old boy was involved in a road traffic accident. A computed tomography scan revealed an acute subdural hematoma (ASDH) of the posterior fossa, traumatic subarachnoid hemorrhage, and distortion of the brain stem. Removal of the ASDH was completed 3.5 h after injury. After extubation, the patient rapidly recovered consciousness. He was able to follow commands, although he did not speak. He began to utter 14 days after the injury. His speech became normal 39 days after injury. A magnetic resonance imaging scan revealed a post-contusional change in the right cerebellum and an ischemic lesion in the pons. DISCUSSION: Immediate removal of the hematoma is the only therapy for patients with ASDH of the posterior fossa. Although any lesions of the dentate nucleus, red nucleus, thalamus, cerebral cortex, and pons, all of which are involved in this case, are able to cause mutism, his mutism was primarily caused by the severe ASDH of the posterior fossa. The transient nature of this syndrome suggests that the cause of the mutism is trauma-related edema and/or transient ischemia of these structures.- - - - - - - - - - ranking = 0.041762098240333keywords = subarachnoid (Clic here for more details about this article) |
