RESUMO

The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo-gical examination excluded mycotic etiology of the aneu-rysm and "normal aneurysm wall" was described. The brain stem haemorrhage - Duret bleeding - was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.

RESUMO

BACKGROUND: Ruptured aneurysms of the intracranial vertebral artery (VA) or posterior inferior cerebellar artery (PICA) are challenging to treat as they are often dissecting aneurysms necessitating direct sacrifice of the diseased segment, which is thought to carry high morbidity due to brainstem and cerebellar stroke. However, relatively few studies evaluating outcomes following VA or proximal PICA sacrifice exist. We sought to determine the efficacy and outcomes of endovascular VA/PICA sacrifice. METHODS: A retrospective series of ruptured VA/PICA aneurysms treated by endovascular sacrifice of the VA (including the PICA origin) or proximal PICA is reviewed. Collected data included demographic, radiologic, clinical, and disability information. RESULTS: Twenty-one patients were identified. Median age was 57 years (IQR 11); 15 were female. The Hunt and Hess grade was mostly 3 and 4 (18/21). Seven cases (33%) involved VA-V4 at the PICA take-off, and 14 cases (67%) involved the PICA exclusively. For VA pathology, V4 was sacrificed in all cases, while for PICA pathology, sacrificed segments included anterior medullary (4/14), lateral medullary (7/14), and tonsillomedullary (3/14) segments. Four patients went to hospice (19%). Twelve patients (57%) had evidence of stroke on follow-up imaging: cerebellar (8), medullary (1), and both (3). One patient required suboccipital decompression for brainstem compression. No aneurysm re-rupture occurred. Median discharge modified Rankin Scale score was 2.0 (IQR 2), which decreased to 1.0 (IQR 1) at median follow-up of 6.5 months (IQR 23). CONCLUSIONS: Endovascular sacrifice of V4 or PICA aneurysms may carry less morbidity than previously thought, and is a viable alternative for poor surgical candidates or those with good collateral perfusion.

RESUMO

INTRODUCTION: Clinically, anterior communicating artery complex fenestration combined with fenestration-related aneurysms is rare, and combination of this condition with tandem aneurysms is even rarer. PATIENT CONCERNS: A case of a 43-year-old man with spontaneous subarachnoid hemorrhage. DIAGNOSIS: A computed tomography angiography examination revealed a fenestrated anterior communicating artery complex combined with 2 aneurysms. Then, a digital subtraction angiography examination was performed to further determine the diagnosis, which showed a complex anatomical structure of the local tissue. After the aneurysms ruptured, they were partially wrapped by a hematoma and compressed, which increased the difficulty of surgery. INTERVENTIONS: An endovascular interventional therapy method was chosen, and a simple coil was successfully inserted through the blood vessel into the tandem aneurysms to maintain the integrity of the anatomical structure. OUTCOMES: The patient recovered well postoperatively. An imaging review after the operation did not show the aneurysms, and the upper and lower branches were patent. CONCLUSION: Therefore, endovascular treatment is an appropriate choice for arterial fenestration combined with tandem aneurysms, once the aneurysms have ruptured.

RESUMO

Coronary-pulmonary artery fistula( CPAF) is a relatively rare congenital malformation. We successfully treated a patient who presented with cardiac tamponade due to ruptured CPAF. A 58-year-old woman was admitted to our hospital due to consciousness disorder. Enhanced computed tomography revealed hemopericardium, and she was diagnosed with cardiac tamponade due to a ruptured coronary artery aneurysm with fistula arising from the right coronary and entering the main pulmonary artery. Therefore, emergency operation was performed. Under cardiopulmonary bypass, the aneurysm was opened and the ostium of the fistula was closed with pledgetted mattress sutures. After ligating the tortuous CPAF, the aneurysmal wall was sutured. Postoperative course was uneventful, and she was discharged on postoperative day 16.

RESUMO

OBJECTIVE: The novel coronavirus disease 2019 (COVID-19) pandemic poses a substantial threat to the health of health care personnel on the front line of caring for patients with COVID-19. The Centers for Medicare and Medicaid Services have announced that all nonessential planned surgeries and procedures should be postponed until further notice and only urgent procedures should proceed. Neurologic surgeries and procedures should not be delayed under the circumstance in which it is essential at saving a life or preserving functioning of the central nervous system. METHODS: With the intent to advise the neurosurgery team on how to adequately prepare and safely perform neurosurgical procedures on confirmed and suspected patients with COVID-19, we discuss considerations and recommendations based on the lessons and experience shared by neurosurgeons in China. RESULTS: Perioperative and intraoperative strategies, considerations, as well as challenges arisen under the specific circumstance have been discussed. In addition, a case of a ruptured aneurysm in a suspected patient with COVID-19 is reported. It is advised that all health care personnel who immediately participate in neurosurgical surgeries and procedures for confirmed and suspected patients with COVID-19 should take airborne precautions and wear enhanced personal protective equipment. CONCLUSIONS: Following the proposed guidance, urgent neurosurgical surgeries and procedures can be safely performed for the benefit of critical patients with or suspected for COVID-19.

RESUMO

BACKGROUND: In aneurysmal subarachnoid hemorrhage (SAH) and multiple intracranial aneurysms (MIAs) identification of the bleeding source cannot always be assessed according to the hemorrhage pattern. Therefore, we developed a statistical model for the prediction of the ruptured aneurysm in patients with SAH and multiple potential bleeding sources at the time of ictus. METHODS: Between 2012 and 2015, 252 patients harboring 619 aneurysms were admitted to the authors' institution. Patients were followed prospectively. Aneurysm and patient characteristics, as well as radiological findings were entered into a computerized database. Gradient boosting techniques were used to derive the statistical model for the prediction of the ruptured aneurysm. Based on the statistical prediction model, a scoring system was produced for the use in the clinical setting. The aneurysm with the highest score poses the highest possibility of being the bleeding source. The prediction score was then prospectively applied to 34 patients suffering from SAH and harboring MIAs. RESULTS: According to the statistical prediction model the main factors affecting the rupture in patients harboring multiple aneurysms were: 1) aneurysm size, 2) aneurysm location and 3) aneurysm shape. The prediction score identified correctly the ruptured aneurysm in all the patients that were used in the prospective validation. Even in the five most debatable and challenging cases assessed in the period of prospective validation, for which the score was designed for, the ruptured aneurysm was predicted correctly. CONCLUSIONS: This new and simple prediction score might provide additional support for neurovascular teams for treatment decision in SAH patients harboring multiple aneurysms. In a small prospective sample, the prediction score performed with high accuracy but larger cohorts for external validation are warranted.

RESUMO

BACKGROUND: Infectious basilar artery (BA) aneurysm has been occasionally reported to be generated from meningitis following transcranial operation. However, infectious BA aneurysm formed by intracranial infection after endoscopic endonasal operation has never been reported. CASE PRESENTATION: A 53-year-old man who was diagnosed with suprasellar region meningioma received tumor removal via endoscopic endonasal approach. After operation he developed cerebrospinal fluid (CSF) leak and intracranial infection. The patient ultimately recovered from infection after anti-infective therapy, but a large fusiform BA aneurysm was still formed and ruptured in a short time. Interventional and surgical measures were impossible due to the complicated shape and location of aneurysm and state of his endangerment, therefore, conservative anti-infective therapy was adopted as the only feasible method. Unfortunately, the aneurysm did not disappear and the patient finally died from repeating subarachnoid hemorrhage (SAH). CONCLUSION: Though extremely rare, it was emphasized that infectious aneurysm can be formed at any stage after transnasal surgery, even when the meningitis is cured. Because of the treatment difficulty and poor prognosis, it was recommended that thorough examination should be timely performed for suspicious patient to make correct diagnosis and avoid fatal SAH.

RESUMO

BACKGROUND: Basilar perforator aneurysms are rare causes of subarachnoid hemorrhage and their natural history is poorly characterized. Although various treatment strategies have been reported, conservative management is an option that has been associated with a high likelihood of spontaneous resolution. CASE DESCRIPTION: Here we present 2 cases of subarachnoid hemorrhage, 1 diffuse and the other perimesencephalic, due to small ruptured basilar perforator artery aneurysms. These aneurysms were only identified after repeat angiography. Conservative management with serial imaging was pursued. Both patients did well clinically and repeat imaging demonstrated spontaneous resolution of the ruptured aneurysms. We also provide a literature review of ruptured basilar perforator aneurysms, showing a ~10% re-rupture rate within the early post-rupture period but otherwise a high rate of spontaneous resolution. CONCLUSIONS: Although basilar perforator aneurysms can re-rupture, there is also a high likelihood of spontaneous resolution. Given the challenges of treatment, conservative management is an option that can be considered.

RESUMO

BACKGROUND: Ruptured intracranial aneurysms are often associated with subarachnoid or intraparenchymal hemorrhage. However, the prevalence of subdural hemorrhage post aneurysmal rupture is low and rarely reported in scientific studies. Here, we report an unusual case of a ruptured posterior communicating artery aneurysm resulting in an isolated subdural hematoma located in the tentorial and spinal canal without subarachnoid or intraparenchymal hemorrhage. CASE PRESENTATION: In this case, a 34-year-old woman with no history of trauma or coagulopathy was diagnosed with a subdural hematoma in the tentorium cerebellum tracing to the subdural space of the spinal column. Computed tomography angiography was used to identify the source of the bleeding, which revealed a ruptured left-sided posterior communicating artery saccular aneurysm. The aneurysm was clipped, and the hematoma was evacuated. The patient recovered without any neurological complications. CONCLUSIONS: Our results suggest that a diagnosis of ruptured intracranial aneurysm should be considered in patients with nontraumatic subdural hematoma. Prompt diagnostic imaging and interventional diagnostic procedures are required to ensure proper management of these patients and to avoid unnecessary complications.

RESUMO

Objevtive: To explore the thoracic ascending aortic (TAA) pathophysiological characteristics of heterozygous mutant Myh11 R247C/+ mice under the norepinephrine-induced hypertension mode. Methods: Female heterozygous mutant Myh11 R247C/+ and wild type Myh11 +/+ mice were selected as experimental group (HET group) and control group (WT group),respectively. The hypertensive model was induced by intraperitoneal injection of norepinephrine (NE),and TAA diameter and invasive blood pressure (Bp) data were collected dynamically in real time using high-frequency ultrasound imaging and invasive arterial blood pressure monitoring technique,so as to indirectly analyze TAA compliance of two groups of mice. At the same time,the incidences of hemothorax and TAA rupture were further analyzed by autopsy and histology. Results: After injection of NE,heterozygous mice did not show a higher Bp increase percentage in systole or diastole comparing with wildtype mice. However,heterozygous mice exhibited 17% and 32% higher TAA diameter dilation percentage than wildtype ones in systole and diastole respectively. Two heterozygous mice had TAA dissection and rupture,and the incidence of hemothorax in heterozygous mice (3/5) was higher than that in wildtype (0/5). Conclusion: It was very likely that the altered TAA wall compliance of mutant Myh11 R247C/+ mice had led to a higher TAA dilation degree than that in wildtype,and even could be the potential reason of TAA dissection and rupture.

RESUMO

Coil embolization for cerebral aneurysms can lead to various complications, such as aneurysm rupture and cerebral embolism. In recent years, foreign substance embolisms-caused by peeling off of coating materials from therapeutic devices-have been described. We report here a case of unilateral multiple cerebral edema four weeks after coil embolization. A 44-year-old woman presented with a subarachnoid hemorrhage from a right internal carotid-posterior communicating artery aneurysm, for which coil embolization was performed. Four weeks after the embolization, she developed numbness in the left side of her mouth and in her left upper extremity. Magnetic resonance images showed multiple edematous lesions in the right cerebral hemisphere. Subsequent treatment with steroids improved her symptoms and edematous cerebral lesions. Although definitive diagnosis by biopsy was not performed, her clinical course and imaging findings resembled a foreign substance embolism by hydrophilic coating. It is important to note that delayed cerebral edema due to foreign substance embolisms might occur after endovascular treatments.

RESUMO

AIM: To summarize the clinical outcomes, follow-up results and to discuss the optimal therapeutic strategy for pericallosal artery aneurysms (PAAs). MATERIAL AND METHODS: From January 2013 to May 2017, the charts of 49 patients with PAAs, representing 2.43% of 2,018 consecutive patients with intracranial aneurysms (IAs) were reviewed. The clinical and radiological data of these patients were retrospectively analyzed. RESULTS: There were no technical failures in the clipping group, but one patient in the coiling group presented rebleeding during the operation, resulting in a poor prognosis. Although the difference was not significant, the coiling group had a better complete recovery rate than the clipping group [overall: coiling, n=20 (87.0%) vs clipping, n=11 (68.8%), p=0.33; unruptured PAAs: coiling, n=12 (92.3%) vs clipping, n=5 (83.3%); ruptured PAAs: coiling, n=8 (80%) vs clipping, n=6 (60%), p=0.63]. One patient in the coiling group exhibited recurrence. No patients experienced rebleeding during the follow-up period in either group. CONCLUSION: In our study, both endovascular coiling and microsurgery were technically feasible and achieved favorable clinical outcomes in patients with PAAs. Longer radiological follow-up is necessary. Patients should be evaluated by a multidisciplinary team prior to determining the optimal treatment modality.

RESUMO

BACKGROUND: Cerebral hyperperfusion syndrome, which carries a potential risk of intracranial hemorrhage, is a rare and overlooked condition in the setting of subarachnoid hemorrhage (SAH). CASE DESCRIPTION: A 72-year-old female presenting with SAH underwent clipping of a ruptured aneurysm of the left middle cerebral artery. On post-SAH day 7, the patient exhibited motor aphasia due to cerebral vasospasm of the left middle cerebral artery. After recovery from symptomatic cerebral vasospasm, the patient became restless and suffered from right hemiparesis on post-SAH day 12. Initially, recurrence of cerebral vasospasm was suspected; however, cerebral blood flow measurement using single-photon emission computed tomography revealed apparently increased perfusion in the same territory of the left middle cerebral artery. Hypertensive therapy was not induced during the postoperative period. Her neurologic symptoms and signs of cerebral hyperperfusion gradually improved with intensive blood pressure lowering. CONCLUSIONS: This is the first report to describe postischemic cerebral hyperperfusion syndrome after symptomatic vasospasm detected using sequential single-photon emission computed tomography during the acute stage of SAH. Early diagnosis of this rare phenomenon is crucial given the necessity to lower blood pressure for preventing hemorrhagic complications, which is contrary to the usual management of patients with vasospasm.
