Corneal Perforation associated with "Silent Brain Syndrome" / Perfuração corneana associada à "síndrome do cérebro silencioso"

ABSTRACT This case report describes the clinical characteristics and ophthalmic management of a patient who developed corneal perforation due to severe enophthalmos consistent with "silent brain syndrome." A 27-year-old man with a history of congenital hydrocephalus and ventriculoperitoneal shunt was referred with complaints of "sinking of the eyeballs" and progressively decreasing vision in the left eye. Examination revealed severe bilateral enophthalmos in addition to superonasal corneal perforation with iris prolapse in the left eye. The patient underwent therapeutic keratoplasty the next day. Orbital reconstruction with costochondral graft and shunt revision of the intracranial hypotension were performed the next month to prevent further progression.

Foi realizado no mês seguinte a reconstrução da órbita com enxerto costocondral e revisão do shunt para evitar progressão e piora do caso.

Surgical management of Dandy-Walker syndrome in infants and the literature review / 中国综合临床

Dandy-Walker syndrome is one of the posterior fossa malformations, which is easily confused with arachnoid cyst or cerebellar dysplasia in clinical practice, leading to misdiagnosis. Dandy-Walker syndrome is easy to be combined with hydrocephalus, resulting in increased intracranial pressure, increased head circumference, growth retardation, spastic hemiplegia and other manifestations, and can also be accompanied by other nervous system malformations. On February 27, 2021, a child with Dandy-Walker syndrome with growth retardation as the primary manifestation was admitted to Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine. After multiple surgical treatment, the child's hydrocephalus was significantly improved. Through the analysis of the clinical data of the child's operation and the treatment of complications, it is helpful to improve the clinicians' understanding of the surgical treatment of the disease.

Epidemiological, therapeutic and evolution aspects of hydrocephalus in children in Madagascar

Hydrocephalus is a disorder of the hydrodynamics of the CSF resulting in an increase in the volume of CSF in the cranial cavity. Hydrocephalus is frequent in Madagascar. We conducted a multicenter and retrospective study of operated hydrocephalic children in 3 neurosurgical departments in Madagascar over a 3-year period. We report 71 cases of hydrocephalus in operated children. Infants predominated in 90.1% of cases. Postmeningeal etiology was found in 42.3%. Ventriculo-peritoneal shunting was undertaken in 92.9% of cases. After the operation, the evolution was favourable in 84.5% of cases. Complications were reported. After discharge from hospital, 59.1% of the children were lost to follow-up within the first month. Hydrocephalus in children predominates in infants. Meningitis remains the most frequent etiology. Ventriculo-peritoneal shunting is the technique most commonly used in Madagascar. The result is favourable in the majority of cases.

Clinical efficacy and safety of laparoscopically assisted ventriculoperitoneal shunting for the treatment of hydrocephalus in older adult patients / 中国基层医药

Objective:To investigate the clinical efficacy and safety of laparoscopically assisted ventriculoperitoneal shunting for the treatment of hydrocephalus in older adult patients.Methods:Sixty-four older adult patients with hydrocephalus who received treatment in Yiwu Fuyuan Private Hospital from June 2017 to December 2019 were included in this study. They were randomly divided into study and control groups, with 32 patients in each group. The control group was given ventriculoperitoneal shunting and the study group was given laparoscopically assisted ventriculoperitoneal shunting. The Fugl-Meyer assessment of motor recovery, the activity of daily life score, hydrocephalus grading score, excellent and good efficacy rate, and incidence of complications were compared between the two groups.Results:After treatment, the Fugl-Meyer score and activity of daily life score in the study group were (77.05 ± 18.54) points and (84.83 ± 17.75) points, which were significantly higher than (63.25 ± 16.18) points and (63.76 ± 15.04) points in the control group ( t = 3.17, P = 0.002; t = 5.12, P < 0.001). Hydrocephalus grading score in the study group was significantly lower than that in the control group [(3.77 ± 2.41) points vs. (6.61 ± 2.75) points, t = 4.39, P < 0.001]. Excellent and good efficacy rate in the study group was significantly higher than that in the control group [93.75% (30/32) vs. 75.00% (24/32), χ2 = 4.26, P < 0.05]. The incidence of complications in the study group was significantly lower than that in the control group [9.38% (3/32) vs. 40.63% (13/32), χ2 = 8.33, P < 0.005]. Conclusion:Laparoscopically assisted ventriculoperitoneal shunting can accurately locate the catheter and is more effective in the treatment of hydrocephalus in older adult patients compared with ventriculoperitoneal shunting. It can accelerate the recovery of neurological function and is highly safe.

Le pseudo kyste abdominal: une complication de la dérivation ventricule péritonéale à propos d'un cas / The abdominal pseudocyst: a complication of ventriculoperitoneal bypass about a case

Le pseudokyste abdominal est une complication rare pouvant survenir chez les sujets porteurs d'une dérivation ventriculo-péritonéale (DVP). Nous rapportons le cas d'un adolescent de 11 ans, chez qui une DVP a été réalisée pour une hydrocéphalie congénitale. Il présentait une distension abdominale progressive sans notion de troubles de transit. L'imagerie (échographie, urosacnner) a permis de mettre en évidence un épanchement péritonéal de grande abondance organisé, à paroi fine et régulière, exerçant un effet de masse sur la vessie et les uretères, responsable d'une urétérohydronéphrose bilatérale. Le bout distal du cathéter de DVP a été visualisé dans la collection

The abdominal pseudocyst is a rare complication that can occur in subjects with a ventriculoperitoneal drain (VPD). We report the case of an 11-year-old adolescent with congenital hydrocephalus antecedent, for whom a ventriculoperitoneal shunt was made. He presented a progressive abdominal distension without notion of transit disorders. Abdominal ultrasound and uroscanner revealed an organized peritoneal effusion of great abundance, thin and regular wall, exerting a mass effect on the bladder and the ureters responsible for bilateral uretero-hydronephrosis. Above all, it has made it possible to individualize the distal ventriculo-peritoneal bypass catheter projecting in the effusion

Hepatic Liquoric Cyst as a Complication of Ventriculoperitoneal Shunt Insertion: A Case Report

Background The ventriculoperitoneal shunt (VPS) procedure is still themost used technique for management of hydrocephalus. This article reports a case of hepatic cerebrospinal fluid (CSF) pseudocyst as a rare, but important, complication of the VPS insertion. Case Description An 18-year-old male presented to the hospital complaining of temporal headache and visual turbidity for approximately 3 months with a history of VPS insertion for treatment of hydrocephalus and revision of the valve in adolescence. The diagnosis was based on abdominal imaging, demonstrating an extra-axial hepatic CSF pseudocyst free from infection. Following the diagnosis, the management of the case consisted in the removal and repositioning of the catheter on the opposite site of the peritoneum. Conclusion The hepatic CSF pseudocyst is an infrequent complication of VPS procedure, but it needs to be considered when performing the first evaluation of the patient. Several techniques are considered efficient for the management of this condition, the choice must be made based on the variables of each individual case.

Complicaciones de la derivación ventriculoperitoneal en pacientes pediátricos. Revisión del tema / Pediatric complications of ventriculoperitoneal shunt. Topic review

RESUMEN Fundamento: La hidrocefalia es un desorden pediátrico frecuente y la colocación de una derivación ventriculoperitoneal es la técnica quirúrgica más usada para su tratamiento. La incidencia de las complicaciones en pacientes pediátricos es un problema frecuente que aumenta la morbilidad y mortalidad. Objetivo: Sistematizar y actualizar los conocimientos relacionados con las complicaciones ventriculoperitoneal es en edad pediátrica. Desarrollo: Las complicaciones asociadas a la derivación ventriculoperitoneal son frecuentes y se pueden dividir en tres grupos: mecánicas, infecciosas y funcionales relacionadas con el drenaje anómalo del líquido cefalorraquídeo, bien por defecto o por exceso. Dentro de las mecánicas, la obstrucción tiene la mayor incidencia seguida de las desconexiones y roturas por adherencias y por las calcificaciones que se forman en el trayecto subcutáneo a lo largo del tiempo. Las obstrucciones tardías predominan en el extremo distal y son motivo frecuente de reintervenciones. Las infecciones del sistema resultan las complicaciones más graves y complejas de tratar acompañándose de una alta mortalidad. Se pueden presentar de forma aguda, subaguda y de manera tardía. Se han identificado diferentes factores que pueden aumentar la incidencia de complicaciones, algunos relacionados con el tipo de válvula y la causa de la hidrocefalia. Conclusiones: Las derivaciones del líquido cefalorraquídeo han sido durante mucho tiempo el tratamiento clásico de la hidrocefalia pediátrica, al poder resolver casi todas sus formas independientemente de la causa. La clave del éxito para evitar las complicaciones está en una adecuada valoración preoperatoria y una rigurosa técnica quirúrgica y garantizar las medidas para la prevención de las infecciones.

ABSTRACT Background: Hydrocephalus is a common pediatric disorder and ventriculoperitoneal shunting is the most commonly surgical technique used for its treatment. The prevalence of pediatric complications is a frequent problem that increases morbidity and mortality. Objective: To systematize and update knowledge on pediatric ventriculoperitoneal complications. Development: Complications associated to ventriculoperitoneal shunting are frequent and can be divided into three groups: mechanical, infectious and functional related to inconsistent drainage of cerebrospinal fluid, either by defect or excess. Within mechanical complications, obstruction has the highest incidence followed by disconnections and ruptures due to adhesions and calcifications formed in the subcutaneous tract over time. Late obstructions predominate in the distal end being a frequent cause of reinterventions. Infections of the system are the most serious and complex complications to treat and are accompanied by high mortality. They can be acute, subacute and late. Unlike identified factors may increase the incidence of complications, some related to the type of valve and the cause of hydrocephalus. Conclusions: Cerebrospinal fluid shunts have been long the classic treatment for pediatric hydrocephalus, able to solve almost all of its different forms regardless of the cause. The key to success in avoiding complications lies in an adequate preoperative assessment and a rigorous surgical technique also endorsing infection prevention measures.

Complicaciones inusuales de las derivaciones ventrículoperitoneales. A propósito de 2 casos pediátricos / Unusual complications of ventriculoperitoneal shunts. About 2 pediatric cases

Introducción: Durante el seguimiento de los pacientes con derivación ventrículoperitoneal (DVP) para el tratamiento de la hidrocefalia se pueden presentar complicaciones habituales relacionadas a la derivación, tales como infecciones u obstrucción/ruptura del sistema derivativo. Sin embargo, raramente se pueden observar complicaciones más raras y graves que pueden afectan a órganos como el corazón y el pulmón. Pacientes y métodos: Presentamos 2 pacientes con raras complicaciones relacionadas a la DVP. El primero, un paciente de 10 años, que después de 7 años de la implantación de una DVP presentó episodios de neumonía recurrente secundaria a la migración intrapulmonar del catéter distal. El segundo caso, un paciente de 3 años, que 5 meses posteriores a la colocación de una DVP presentó síntomas de hipertensión endocraneana secundarios a migración intracardíaca del catéter distal. Conclusión: La migración intrapulmonar e intracardíaca del catéter distal son complicaciones extremadamente raras, pero que pueden producir morbilidad importante. Los pacientes con derivación ventrículoperitoneal deben ser controlados de forma rutinaria de por vida, con la finalidad de evitar comorbilidades asociadas a sus complicaciones.

Introduction: during the follow-up of patients with ventriculoperitoneal (VP) shunts for the treatment of hydrocephalus, common complications may occur, such as infections or obstruction/rupture of the shunt system. However, more rare and serious complications that affect organs such as the heart and lungs can be observed Patients and methods: we present 2 patients with rare complications related to VP shunts. The first, a 10-year-old patient, who 7 years after implantation of a VP shunt, presented episodes of recurrent pneumonia secondary to intrapulmonary migration of the distal catheter. The second case, a 3-year-old patient, who 5 months after the placement of a VP shunt, presented with symptoms of intracranial hypertension secondary to intracardiac migration of the distal catheter. Conclusion: intrapulmonary and intracardiac migration of the distal catheter are extremely rare complications, but they can cause significant morbidity. Patients with ventriculoperitoneal shunts should be routinely monitored for life by neurosurgeons, in order to avoid comorbidities associated with potential complications.

Galen Vein Aneurysm: Problem of Management in an Under-Equipped Neurosurgical Environment about a Case and Review of the Literature

Vein of GALEN aneurysmal malformation (VGAM) is a rare congenital disease caused by arteriovenous shunts between the choroidal arteries and the porencephalic ectatic vein. The diagnosis is often made in utero or during infancy, endovascular treatment remains the most suitable therapeutic means in a well-equipped environment. Here we report here the case of a patient complaining of headache for 1 year, and whose brain CT imaging showed the presence of Galen veinaneurysm with associated non-communicating hydrocephalus. In the absence of the appropriate technical platform, the placement of a ventriculoperitoneal shunt relieved our patient’s symptoms

An analysis of factors determining the requirement of ventriculoperitoneal shunt surgery in the children suffering from posterior fossa tumour: a single centre retrospective review

Background: Hydrocephalus is a relatively common occurrence in a children suffering from the posterior fossa tumour (PFTm). However, there is a divided opinion regarding the ventriculoperitoneal shunt (VPS) surgery before the posterior fossa tumour resection in a child. For the better clinical outcome, we should be able to predict which patient will require VPS following the resection of PFTm. Purpose of our retrospective analysis is to analyse various factors that predicts the necessity of VPS following PFTm resection.Methods: A consecutive series of twenty-six patients who underwent PFTm resection without undergoing VPS preoperatively are analysed in our series.Results: In our series, we found that the younger age at presentation, incomplete tumour resection, longer period of artificial ventilatory support, insertion of external ventricular drain (EVD) and its duration during the postoperative period correlate the necessity of VPS following PFTm resection. However, the severity of hydrocephalus prior to tumor surgery, tumour size, anatomical location of the tumour, tumour dissemination, use of Dural grafts during closure and histopathological type do not predict the requirement of the VPS following PFTm.Conclusions: Patients who are younger at diagnosis should be treated with utmost importance. Gross total resection should be the goal. Factors which predict the likelihood of the EVD which parallels the likelihood of postresection hydrocephalus must be prevented for the better clinical outcome.

Clinical performance of fixed-pressure Sphera Duo® hydrocephalus shunt / Performance clínica da válvula de pressão fixa Sphera Duo®

Abstract Introduction: Cerebral hydrodynamics complications in shunted patients are due to the malfunction of the system. The objective of this retrospective, single-center, single-arm cohort study is to confirm the safety and performance of Sphera® Duo when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cysts. Methods: Data were generated by reviewing 112 adult patient's charts, who were submitted to a ventriculoperitoneal shunt surgery and followed for one year after surgery. Results: The results show us that 76% of patients had their neurological symptoms improved and that the reoperation rate was 15% in the first year following surgery. Discussion: Sphera Duo® shunt system is an applicable shunt option in routine neurosurgical management of hydrocephalus by several causes. It has presented good results while mitigating effects of overdrainage. Overdrainage is especially important in adults with non-hypertensive hydrocephalus and can cause functional shunt failure, which causes subnormal ICP (particularly in the upright position) and is associated with characteristic neurological symptoms, such as postural headache and nausea. Conclusion: Sphera Duo® shunt system is safe when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cyst.

Resumo Introdução: As complicações da hidrodinâmica cerebral em pacientes com derivação ventriculoperitoneal são frequentemente relacionadas ao malfuncionamento do sistema. O objetivo deste estudo retrospectivo de coorte de centro único é avaliar a segurança e performance clínica do Sistema Sphera® Duo quando utilizado em adultos com hidrocefalia, pseudotumor cerebral ou cistos aracnoides. Métodos: Avaliamos os prontuários de 112 pacientes adultos submetidos a cirurgia de derivação ventriculoperitoneal e acompanhados por 1 ano após a cirurgia. Resultados: O resultado mostra que 76% dos pacientes melhoraram dos sintomas neurológicos e a taxa de reoperação foi de 15% no primeiro ano após a cirurgia. Discussão: O sistema de derivação Sphera Duo® é uma opção de shunt adequada a ser usada no tratamento neurocirúrgico da hidrocefalia por causas diversas. Ele demonstrou bons resultados clínicos enquanto reduziu riscos de hiperdrenagem. A hiperdrenagem é especialmente preocupante e mórbida em pacientes adultos com hidrocefalia não hipertensiva e pode levar a prejuízo clínico e disfunção da válvula, com sintomas de hipotensão craniana, como cefaléia ortostática e náuseas. Conclusão: O sistema de derivação Sphera Duo® é seguro para tratamento da hidrocefalia, pseudotumor cerebri ou cistos aracnóides em adultos.

Neuroinfección por Vibrio cholerae no O1/ no O139 secundaria a la derivación ventriculoperitoneal. Reporte de caso / Vibrio cholerae no o1/ no 0139 neuroinfection secondary to ventriculoperitoneal shunt: case report

RESUMEN La infección de la derivación ventriculoperitoneal es una de las complicaciones más frecuentes en este procedimiento. Vibrio cholerae O1 y O139 es una bacteria gram negativa conocida principalmente por ser la responsable del cólera epidémico. No obstante, existen serotipos no O1/ no O139 capaces de causar afecciones extraintestinales, entre ellas se han reportado casos de neuroinfección. Presentamos el caso de una paciente con 9 meses de edad que posterior a la colocación de una derivación ventriculoperitoneal como tratamiento de hidrocefalia obstructiva congénita, presentó un cuadro de neuroinfección y el síndrome de malfunción valvular; se pudo aislar la Vibrio cholerae no O1/ no O139 en el líquido cefalorraquídeo y en la punta del catéter. Es el primer reporte en la literatura en la que se aísla la Vibrio cholerae no O1/ no O139 en líquido cefalorraquídeo secundario a infección de una derivación ventriculoperitoneal.

SUMMARY The infection of the ventriculoperitoneal shunt is one of most frequent complications for this procedure. Vibrio cholera O1 and O139 is a Gram negative bacteria known mainly for being responsible of the epidemic cholera, however, there are serotypes no O1/ no O139 capable of causing extraintestinal conditions, among them neuroinfection cases have been reported. We present the case of a 9 months old patient who after the placement of a ventriculoperitoneal shunt as treatment for connate obstructive hydrocephalus, presents a neuroinfection condition and valve malfunction syndrome, being able to isolate the Vibrio cholerae no O1/ no O139 in the cerebrospinal fluid and the tip of the catheter. It is the first report in the literature in which the Vibrio cholerae no O1/ no O139 is isolated in the cerebrospinal liquid secondary to an infection from a ventriculoperitoneal shunt.

Outcome Analysis of Ventriculoperitoneal Shunt in Terms of Complications In Patients of Congenital Hydrocephalus

Introduction: Ventriculo-peritoneal shunt is routinelyperformed in neurosurgery especially in PediatricNeurosurgery. This study is a retrospective study to analyzethe complications occurring in patients of congenitalhydrocephalous who got operated at our centre.Materials and Methods: This study was done by analyzing 90cases referred to Department of Neuro Surgery, SSG CivilHospital, Baroda Medical College, Baroda, Gujarat, India fromNovember 2017 to April 2019. A minimum follow-up of 6months was done. Hydrocephalus associated with Spaceoccupying lesions, Intracranial hemorrhages, Neural tubedefects were excluded.Results: Total number of cases operated during this periodwas 90. 59(65.6%) were male, 31 (34.4%) were female.Complications were observed in 30/90 (33.3%) cases. Out of30 cases shunt block 16 cases (53.4%) was a major cause ofcomplication followed by Infection i.e. 6 cases (20%). Therewas no mortality observed in our cases.Conclusion: This procedure has a high complication rate butnow due to again popular endoscopic third ventriculostomywhich can be safely used in certain cases above a set age, hasgiven us an option, but still in age group of 0-6 monthsventriculo-peritoneal shunt is still a more popular andprocedure of choice till any further alternative is available.

Cerebellar infarction complicated with acute hydrocephalus

Acute hydrocephalus is a rare manifestation of posterior circulation strokes. Clinical worsening and coma may occur in addition to these symptoms of cerebellar dysfunction. Timely and careful approach will certainly prove to be life saving when deciding for a shunt procedure in a patient developing obstructive hydrocephalus following cerebellar infarct. The case presented here is a reminder for both this rare complication, and the treatment approach. We present a patient with cerebellar infarct and secondary obstructive hydrocephalus. Forty three year old male patient was brought to the emergency room in our hospital with unconsciousness, before that patient with suddenly developing dizziness, loss of balance and vomiting. His neurological examination showed that he was coma. The patient's brain computed tomography scan showed severe third and lateral ventricular dilation suggestive of obstructive hydrocephalus. Following shunt placement and suboccipital decompression, the patient recovered and was able to walk without assistance. Cerebellar infarcts may cause death as a result of pressure increase in the posterior fossa and pressure on the brain stem due to edema. Moreover, the aquaductus or the fourth ventricle may close because of edema and cause obstructive hydrocephalus and acute intracranial pressure increase. Temporary external ventricular drainage or permanent shunt systems and surgical decompression of the posterior fossa may be considered to prevent progressive neurologic worsening. In conclusion, we wished to point out that a timely surgical procedure in a cerebellar infarct case where acute hydrocephalus developed could be life saving.

Neurological Symptoms of Intracranial Hypotension

Intracranial hypotension usually arises in the context of known or suspected leak of cerebrospinal fluid (CSF). This leakage leads to a fall in intracranial CSF pressure and CSF volume. The most common clinical manifestation of intracranial hypotension is orthostatic headache. Post-dural puncture headache and CSF fistula headache are classified along with headache attributed to spontaneous intracranial hypotension as headache attributed to low CSF pressure by the International Classification of Headache Disorders. Headache attributed to low CSF pressure is usually but not always orthostatic. The orthostatic features at its onset can become less prominent over time. Other manifestations of intracranial hypotension are nausea, spine pain, neck stiffness, photophobia, hearing abnormalities, tinnitus, dizziness, gait unsteadiness, cognitive and mental status changes, movement disorders and upper extremity radicular symptoms. There are two presumed pathophysiologic mechanisms behind the development of various manifestations of intracranial hypotension. Firstly, CSF loss leads to downward shift of the brain causing traction on the anchoring and supporting structures of the brain. Secondly, CSF loss results in compensatory meningeal venodilation. Headaches presenting acutely after an intervention or trauma that is known to cause CSF leakage are easy to diagnose. However, a high degree of suspicion is required to make the diagnosis of spontaneous intracranial hypotension and understanding various neurological symptoms of intracranial hypotension may help clinicians.

Risk Factors and Preoperative Risk Scoring System for Shunt-Dependent Hydrocephalus Following Aneurysmal Subarachnoid Hemorrhage

OBJECTIVE: Shunt-dependent hydrocephalus (SdHCP) is a well-known complication of aneurysmal subarachnoid hemorrhage (SAH). The risk factors for SdHCP have been widely investigated, but few risk scoring systems have been established to predict SdHCP. This study was performed to investigate the risk factors for SdHCP and devise a risk scoring system for use before aneurysm obliteration. METHODS: We reviewed the data of 301 consecutive patients who underwent aneurysm obliteration following SAH from September 2007 to December 2016. The exclusion criteria for this study were previous aneurysm obliteration, previous major cerebral infarction, the presence of a cavum septum pellucidum, a midline shift of >10 mm on initial computed tomography (CT), and in-hospital mortality. We finally recruited 254 patients and analyzed the following data according to the presence or absence of SdHCP : age, sex, history of hypertension and diabetes mellitus, Hunt-Hess grade, Fisher grade, aneurysm size and location, type of treatment, bicaudate index on initial CT, intraventricular hemorrhage, cerebrospinal fluid drainage, vasospasm, and modified Rankin scale score at discharge. RESULTS: In the multivariate analysis, acute HCP (bicaudate index of ≥0.2) (odds ratio [OR], 6.749; 95% confidence interval [CI], 2.843–16.021; p=0.000), Fisher grade of 4 (OR, 4.108; 95% CI, 1.044–16.169; p=0.043), and an age of ≥50 years (OR, 3.938; 95% CI, 1.375–11.275; p=0.011) were significantly associated with the occurrence of SdHCP. The risk scoring system using above parameters of acute HCP, Fisher grade, and age (AFA score) assigned 1 point to each (total score of 0–3 points). SdHCP occurred in 4.3% of patients with a score of 0, 8.5% with a score of 1, 25.5% with a score of 2, and 61.7% with a score of 3 (p=0.000). In the receiver operating characteristic curve analysis, the area under the curve (AUC) for the risk scoring system was 0.820 (p=0.080; 95% CI, 0.750–0.890). In the internal validation of the risk scoring system, the score reliably predicted SdHCP (AUC, 0.895; p=0.000; 95% CI, 0.847–0.943). CONCLUSION: Our results suggest that the herein-described AFA score is a useful tool for predicting SdHCP before aneurysm obliteration. Prospective validation is needed.
