Risk factors, treatment, and outcome in dogs and cats with subdural hematoma and hemispheric collapse after ventriculoperitoneal shunting of congenital internal hydrocephalus. J Vet Intern Med 2023; 37:2269-2277. [PMID: 37675951 PMCID: PMC10658535 DOI: 10.1111/jvim.16861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 08/24/2023] [Indexed: 09/08/2023] Open
Abstract
BACKGROUND Overshunting and hemispheric collapse are well-known complications after ventriculoperitoneal shunt (VPS) implantation. Risk factors that predispose to overshunting, treatment options, and prognosis after therapeutic intervention have not been described. HYPOTHESIS/OBJECTIVES To identify preoperative risk factors for overshunting, the effect of surgical decompression, and their outcomes. ANIMALS Seventy-five dogs and 7 cats. METHODS Retrospective case cohort study. Age, breed, sex, body weight, number of dilated ventricles, ventricle brain ratio, intraventricular pressure, and implanted pressure valve systems were evaluated as possible risk factors. RESULTS Overshunting had a prevalence of 18% (Cl 95% 9.9-26.66). An increase of 0.05 in VBR increased the risk of overshunting by OR 2.23 (Cl 95% 1.4-3.5; P = .001). Biventricular hydrocephalus had the highest risk for overshunting compared to a tri- (OR 2.48 with Cl 95% 0.5-11.1) or tetraventricular hydrocephalus (OR 11.6 with Cl 95% 1.7-81.1; P = .05). There was no influence regarding the use of gravitational vs differential pressure valves (P > .78). Overshunting resulted in hemispheric collapse, subdural hemorrhage, and peracute deterioration of neurological status in 15 animals. Subdural hematoma was removed in 8 dogs and 2 cats with prompt postoperative improvement of clinical signs. CONCLUSIONS AND CLINICAL IMPORTANCE Biventricular hydrocephalus and increased VBR indicate a higher risk for overshunting. The use of differential valves with gravitational units has no influence on occurrence of overshunting related complications and outcomes. Decompressive surgery provides a favorable treatment option for hemispheric collapse and has a good outcome.

Abstract
Postoperative remote intracranial hemorrhage (rICH) secondary to craniotomy surgery is an extremely rare but catastrophic complication. The present study aimed to investigate the incidence and the possible pathophysiological mechanism of rICH after brain tumor surgery. The clinical data from 9 rICH cases among 4588 patients undergoing brain tumor surgery were collected retrospectively. Remote intracranial hemorrhage occurred in 9 cases, including 6 cases of remote epidural hemorrhage (rEDH), 2 cases of remote subdural hemorrhage (rSDH), and 1 case of remote cerebellar hemorrhage (rCBH). Among the 9 cases, 2 were males and 7 were females, with an age range of 22 to 63 years (mean of 44.3 years). The incidence of rICH in the patients with ventricular system opening/drainage (4/258) was much higher than the patients without ventricular system opening/drainage (5/4330), and the difference was statistically significant (P < 0.01). Hematoma evacuation was performed in 7 patients with serious neurological status or massive hematoma. The outcome for most of the rICH cases was good, and the Glasgow outcome scale scores of 4-5 were found in 8 cases with a 3-month-long follow-up. Our results suggest that brain tumor surgery with ventricular system opening/drainage was more susceptible to rICH. Paying particlular attention to gradual reduction of intracranial pressure and avoiding excessive loss of cerebrospinal fluid may aid to prevent the occurrence of rICH. The authors suggest that a high index of suspicion, a prompt diagnosis, and emergent management is of vital importance to achieve good prognosis for rICH patients secondary to brain tumor surgery.

Abstract
Background The occurrence of remote epidural hematoma as a postoperative complication after intracranial tumor resection is rare. This study reviewed experiences treating these hematomas and speculated on the causes of this disease. This study reviewed the treatment experience of 14 such cases. Methods The 14 patients included 10 males and 4 females, with an age range of 19 to 65 years old. Six cases of tumors occurred in the sellar region, two cases in the lateral ventricle, one case in the fourth ventricle, one case in a cerebellar hemisphere, and four cases in other sites. Among them, five cases were complicated with supratentorial hydrocephalus. The tumors included five cases of meningioma tumors, two cases of pituitary adenomas, three cases of ependymomas, two cases of craniopharyngiomas, one case of astrocytoma, and one case of tuberculosis tumor. For the cases complicated with hydrocephalus, ventricular drainage was provided if needed, and the tumor resection was then performed, with close observation for postoperative changes. If neurological symptoms and disturbance of consciousness occurred, computed tomography (CT) examination was immediately performed. If a remote epidural hematoma was found, the hematoma was evacuated by craniotomy. The patients were followed up after surgery. In the five cases complicated with hydrocephalus, ventricular drainage was first provided for three cases. Results All of the 14 cases underwent total tumor resection, and postoperative remote epidural hematoma occurred in all cases, including eight cases on the ipsilateral side and adjacent to the supratentorial operative field; two cases occurred on the contralateral side; two cases occurred on bilateral sides; and two cases occurred in distant areas (with infratentorial surgery, the hematoma occurred on the supratentorial area). Postoperative remote epidural hematoma usually occurred 0.5–5 h after the tumor resection, when the tentorial hernia had already occurred. Following tumor resection and epidural hematoma evacuation, 13 patients were discharged with good recovery, and one patient died. Conclusions The reduced intracranial pressure due to the intracranial tumor resection may be the cause of this hematoma. This type of epidural hematoma is acute and often occurs before hernia. Thus, the risk of remote epidural hematoma after intracranial tumor resection needs to be made known. Aggressive hematoma evacuation can often result in satisfactory outcomes for patients.

Abstract
BACKGROUND Endoscopic third ventriculostomy (ETV) is an ideal treatment for obstructive hydrocephalus. Although ETV is a safe procedure, several complications related to this procedure have been reported in the literature. We present a rare case of late onset symptomatic bilateral subdural hematoma after an uneventful ETV that proved particularly difficult to solve. CASE DESCRIPTION A 61-year-old male patient presented in our neurosurgery department three months after ETV (aqueductal stenosis) with progressive headaches and anomic aphasia. The MRI revealed bilateral chronic subdural hematomas (chSDH). They were treated via a burr hole evacuation, subduroperitoneal and external subdural drains proving to be refractory to the first two strategies. Postoperatively, his headaches improved. At the last follow-up the patient's status remains improved and there is no radiological evidence of significant residual collections. CONCLUSION This case confirms that chSDH formation is a rare possible complication following ETV even in the presence of a normal early postoperative image. Patients should be followed-up more closely for possible subdural collection formation. In the cases of very long-term hydrocephalus with a thin cerebral mantle, brain elastic properties are likely to be altered. As there is no possibility to close the internal shunt, the stoma, we advocate external subdural drainage to reinflate the brain, in the first intention or at least after an initial failed burr hole evacuation.

Abstract
BACKGROUND Endoscopic procedure has been known as the method of choice for treatment of hydrocephalus with 8.5% complication rate. It seems that good dural closure, reconstructing bone defect and perfect pericranium suturing can decrease the wound complications. Here, we describe the method of minicraniotomy instead of the burr hole in the endoscopic procedure. MATERIALS AND METHODS A case-control study regarding the cranial opening for endoscopic surgery was done in 45 patients of <12 months age; 15 patients in case group for minicraniotomy and 30 infants as control group for burr hole. They were followed at least 1-month for complications including cerebrospinal fluid collection, wound dehiscence, wound infection, and meningitis. RESULT Patients were between 1 and 11 months. Hydrocephalus (73%) was the most common etiology for endoscopic surgery in this series, followed by the arachnoid cyst (20%). Two patients in the case group and eight in control group developed complications. Meningitis was found in one infant in the control group. Despite less complications in the case group the difference between two cohorts was not statistically significant. CONCLUSION Minicraniotomy with providing more space in comparison to burr hole makes dural closure possible. It provides a small bone flap that can be replaced inside the bone defect. In spite of nonsignificant statistical difference between two groups regarding complication rate, we found less wound complications with minicraniotomy. Therefore, we advise this technique for the endoscopic procedure and propose minicraniotomy even in the older population to provide better dural opening, watertight dural closure and reconstructing the bone defect.

Abstract
PURPOSE As the number of endoscopic third ventriculostomy (E3V) operations increase, new rare complications are encountered. In this article, a complication caused by bone particles that migrated into the third ventricle will be described. Additionally, the methods of avoidance as well as the necessity of a new approach will be discussed. METHODS After the video images of the first and second operations of a patient who was subjected to E3V twice were compared, it was discovered that one of the bone particles within the ventricle had occluded the ostium after the second operation. Most of the bones were removed and their pathological investigations were performed. RESULTS Video images of the patient, surgical observations of the second operation, emergence of the time of dysfunction, and other similar cases in the literature were assessed, and it was concluded that the bones that localized intraventricularly were living tissues. DISCUSSION Abandoning usage of bone dust for sealing burr holes is a solution to avoid this complication. In addition, it should be kept in mind that intraventricular bone particles might grow and lead to obstructions. If such particles are detected, removal of the bones in certain locations before formation of neovascularization can be an option.

Abstract
PURPOSE Endoscopic third ventriculostomy (ETV) has become standard for obstructive hydrocephalus. Even a successful ETV can obstruct, leading to recurrence of symptoms and even death. A possible solution to this problem is leaving an Ommaya reservoir (OR) following the ETV. OR can be tapped in an emergency and for diagnostic purposes. No specific complications have been attributed to OR in this setting. We present our experience with OR in children undergoing ETV for hydrocephalus. MATERIALS AND METHODS A retrospective study was conducted in hydrocephalic children that underwent ETV with OR insertion over 13 years (1997-2010) from a single institution. Data were collected from charts and follow-ups. RESULTS Twelve patients (from 200 patients who had an ETV) underwent placement of OR with ETV. OR was reserved for a subgroup of patients in whom we anticipated complications-in children that presented with acute hydrocephalus and were in deteriorating condition, for pathologies believed to have a low predicted ETV success rate, or when the surgeon felt that the ETV procedure was suboptimal. OR was tapped in eight patients. Complications occurred in four patients: two cases of subdural effusion, one case of chronic subdural hematoma, and one CSF leak. Four ORs were removed due to complications, and four were converted to shunts. CONCLUSIONS OR should be considered in selected patients undergoing ETV. Despite its obvious advantages, OR may be associated with a relatively high risk of extraaxial fluid collections. This association requires further investigation.

Abstract
OBJECTS Although endoscopic third ventriculostomy (ETV) is considered as the first choice in the management of noncommunicating hydrocephalus, it is not without risk or complication. METHODS The patients who had undergone ETV only between 1998 and 2005 were retrospectively reviewed. There were 85 males and 70 females, and 173 ETVs were performed in 155 patients. The patients' age ranged from 2 months to 77 years. Complications were categorized as (1) intraoperative, (2) early postoperative (<1 month), and (3) late postoperative (>1 month). Follow-up of the patients ranged from 1 to 86 months. RESULTS Overall complication rate per patient was 15.4%, and complication per procedure was 18%. Complication rate significantly varied with the etiology of hydrocephalus (P = 0.013). The patients with Chiari type I malformation and tumor had no or very low complication rates. The complication risk was significantly higher in repeat endoscopic procedure (55.5%) than in the first procedure (10%; P = 0.0001). CONCLUSION ETV should be the first choice in the management of noncommunicating hydrocephalus. Training, experience, and meticulous technique will decrease the complication rate. Patients undergoing ETV should be followed in a similar manner to patients with cerebrospinal fluid shunts.

Abstract
BACKGROUND Overdrainage in shunted patients is a known predisposing factor for the formation of hygromas, but little is known about risk factors in endoscopic third ventriculocisternostomy (ETV). MATERIALS AND METHODS We retrospectively analysed data of 34 patients younger than 1 year with obstructive hydrocephalus, undergoing ETV, with respect to incidence, management, outcome and possible risk factors for the formation of hygromas. Hygromas were arbitrarily defined as a collection of cerebrospinal fluid of more than 10 mm in diameter over the paramedian hemispheric convexities, diagnosed by ultrasonography. RESULTS They occurred in 9 of 34 (26%) patients 3 to 28 days after ETV. They were on the operated side in four and bi-lateral in five cases. There was no relevant age difference between patients with hygromas (median 127 days) and those without hygromas (median 166 days). Etiology of obstructive hydrocephalus had no impact on the frequency of hygromas. Hygromas occurred somewhat less frequently when a paediatric endoscope with an outer diameter of 3 mm was used for ETV instead of an endoscope with a diameter of 6 mm. Hygromas were asymptomatic and conservatively managed in five cases; 4 of 34 (12%) patients underwent surgery because of clinical symptoms of increasing intracranial pressure or increasing hygroma diameter. Two patients were treated with a temporary external drainage only and another two patients with an external drainage first and eventually a subduro-peritoneal shunt. There were no neurological long-term sequelae. CONCLUSION Clear predisposing factors for the formation of hygromas could not be identified, but the outer diameter of the endoscope may play a role.

Abstract
BACKGROUND The significant technological improvement of endoscopic instrumentation has allowed, in the last 10 years, a widespread diffusion of neuroendoscopic procedures. Nevertheless, severe, sometimes life-threatening, complications may occur during neuroendoscopic surgery, and the incidence and age specificity of complications in children have been underdescribed so far. MATERIALS AND METHODS Complications recorded in a prospectively collected database of pediatric patients undergoing neuroendoscopic procedures were analysed; the medical histories of the patients and the surgical procedures were reviewed. RESULTS Complications occurred in 32 out of 231 (13.8%) procedures performed for the management of obstructive hydrocephalus (137), multiloculated hydrocephalus (53), arachnoid cysts (29) and intraventricular tumors (12). Subdural hygroma occurred in 11 cases, seven requiring subdural shunting. In one of these cases, infection of the subdural space occurred and required a craniotomy. Cerebrospinal fluid (CSF) infection occurred in 11 cases. In one case, a frontal abscess developed and was managed with craniotomy. CSF leak occurred in nine cases, intraventricular haemorrhages in two, technical failures in seven, subcutaneous CSF collection (managed with lumbo-peritoneal shunt) in one, thalamic contusion and post-operative transient akinetic mutism in one. This patient suddenly died 6 months later, probably as a consequence of closure of the stoma. Two patients developed secondary compartmentalisation of the ventricles after complicated endoscopic third ventriculostomy. In nine cases, these complications were associated. Overall, no patient died after the procedure (operative mortality 0), one patient died 6 months after the procedure for unexplained events (sudden death rate 0.4%), and three patients presented permanent disability as a consequence of surgical complication (permanent morbidity 1.3%). CONCLUSIONS Complication rate of neuro-endoscopic procedures is not negligible even in experienced hands. The majority are minor complications which do not affect the final outcome, but sporadically major events may occur, leading to significant problems in surgical management and, occasionally, to permanent disabilities. Careful selection of patients on pre-operative imaging studies and intensive training of surgeons are mandatory to improve results.
