RESUMO
Chronic subdural hematoma is one of the most common neurosurgical pathologies with over 160,000 cases in the United States and Europe each year. The current standard of care involves surgically evacuating the hematoma through a cranial opening, however, varied patient risk profiles, a significant recurrence rate, and increasing financial burden have sparked innovation in the field. This mini-review provides a brief overview of currently used evacuation techniques, including emerging adjuncts such as endoscopic assistance and middle meningeal artery embolization. This review synthesizes the body of available evidence on efficacy and risk profiles for each critical aspect of surgical technique in cSDH evacuation and provides insight into trends in the field and promising new technologies.
RESUMO
Objective: The subdural evacuating port system (SEPS) is a minimally invasive approach that can be performed under local anesthesia for the treatment of chronic subdural hematoma (CSDH). Subdural thrombolysis has been described as an exhaustive drainage strategy and found to be safe and effective for improving drainage. We aim to analyze the effectiveness of SEPS with subdural thrombolysis in patients older than 80 years. Method: Consecutive patients aged ≥80 years old who presented with symptomatic CSDH and underwent SEPS followed by subdural thrombolysis between January 2014 and February 2021 were retrospectively studied. Outcome measures included complications, mortality, recurrence, and modified Rankin Scale (mRS) scores at discharge and 3 months. Results: In total, 52 patients with CSDH in 57 hemispheres were operated on, with a mean age of 83.9 ± 3.3 years, and 40 (76.9%) patients were men. The preexisting medical comorbidities were observed in 39 patients (75.0%). Postoperative complications occurred in nine patients (17.3%), with two having significant complications (3.8%). The complications observed included pneumonia (11.5%), acute epidural hematoma (3.8%), and ischemic stroke (3.8%). One patient experienced contralateral malignant middle cerebral artery infarction and died of subsequent severe herniation, contributing to a perioperative mortality rate of 1.9%. Discharge and 3 months of favorable outcomes (mRS score 0-3) were achieved in 86.5% and 92.3% of patients, respectively. CSDH recurrence was observed in five patients (9.6%), and repeat SEPS was performed. Conclusion: As an exhaustive drainage strategy, SEPS followed by thrombolysis is safe and effective with excellent outcomes among elderly patients. It is a technically easy and less invasive procedure with similar complications, mortality, and recurrence rates compared with burr-hole drainage in the literature.
RESUMO
Background: Subacute subdural hematoma (SDH) is a common pathology most frequently affecting older patients and may be treated operatively through burr holes versus craniotomy or minimally invasively with bedside twist drill craniostomy. Less invasive intervention is favored when possible given a frequently comorbid population. The subdural evacuation port system (SEPS) is a popular treatment option that warrants investigation and reporting of its use and outcomes. Methods: A retrospective review of consecutive patients undergoing SEPS drain placement for chronic or mixed density SDH between 2010 and 2021 was conducted. Outcomes of SDH recurrence, need for operating room procedure after SEPS placement, discharge disposition other than home, and modified Rankin Scale score <3 at discharge were modeled with logistic regression using multiple demographic, clinical, and radiographic features. Results: Ultimately, 86 patients (mean age 68) were included in the analysis with 66 (78%) presenting with mixed-density SDHs. Radiographic factors such as hematoma thickness and midline shift were not associated with the need for an operating room procedure after SEPS placement or discharge disposition. However, the presence of septations and mixed-density SDH versus chronic SDH was significantly associated with increased odds of requiring an operative intervention after SEPS placement. Conclusions: Subacute SDHs are a frequent neurosurgical issue in patient populations where less invasive measures are favored. SEPS drainage continues to be an effective treatment option. However, the presence of septations and mixed-density SDHs has a significantly increased odds of requiring surgical intervention that must be considered in the decision to pursue SEPS drainage.
RESUMO
Background: Tension pneumocephalus is a neurosurgical emergency requiring prompt intervention. A variety of either temporizing or definitive methods was previously described as part of its management. Here, we report on an off-label use of a bed-side device and the subdural evacuating port system (SEPS)™ for the treatment of tension pneumocephalus. Methods: The SEPS™ (Medtronic Dublin, Ireland) is a minimally invasive tool that is indicated for the removal of chronic or subacute subdural hematomas and at the patient's bedside. We describe the use of this system to evacuate tension pneumocephalus. Results: A 44-year-old patient operated in our institution was presented with sudden obtundation 4 days post resection of esthesioneuroblastoma. Imaging confirmed a significant tension pneumocephalus. Immediate bedside decompression using a SEPS bolt placed frontally was performed, achieving rapid evacuation and patient regained consciousness. A definitive skull base reconstruction was done at the operating room at a later stage. Conclusion: The SEPS™, well-known for evacuation of CSDH, can be potentially used as a bed-side tool to effectively treat mass effect created by tension pneumocephalus. As a readily-available and commercially used device, it can provide a simple and standard toolkit suitable for an emergent temporizing procedure.
RESUMO
Tension pneumocephalus (TP) is a rare neurosurgical emergency due to the rise of intracranial pressure from air in the cranial cavity. Tension pneumocephalus' clinical presentation ranges from headache, visual alterations, altered mental status, and death. Given its nonspecific clinical presentation, tension pneumocephalus is usually diagnosed via computed tomography (CT) imaging. Open burr hole craniotomy is the preferred treatment method for tension pneumocephalus. Subdural evacuating port system (SEPS) drains have, however, seen increased utilization in neurosurgery due to decreased possibilities for infections, reduced seizure probability, and better outcomes post-surgery, especially for elderly patients. In this article, we present the case of a 67-year-old female with postoperative tension pneumocephalus after the evacuation of an acute subdural hematoma. The patient became symptomatic from tension pneumocephalus, which was evacuated using a subdural evacuating port system drain. Post-drain placement, the patient had a radiographic and clinical resolution of her tension pneumocephalus. Thesubdural evacuating port system is a useful adjunctive tool for treating tension pneumocephalus.Given the favorable characteristic profile of subdural evacuating port system drains compared to open surgical modalities, further inquiry should be pursued to analyze the feasibility of establishing subdural evacuating port systems as a less invasive treatment alternative.
RESUMO
The subdural evacuating port system (SEPS) is a minimally invasive option for treating chronic subdural hematoma (cSDH). Individual case series have shown it to be safe and effective, but outcomes have not been systematically reviewed. We sought to review the literature in order to determine the safety and efficacy of SEPS as a first line treatment for cSDH. A comprehensive literature search for outcomes following SEPS placement as a primary treatment for cSDH was performed. The primary outcome was treatment success, which was defined as a composite of improvement in presenting symptoms and no need for further treatment in the operating room. Additional outcomes included discharge disposition, length of stay (LOS), hematoma recurrence, and complications. A total of 12 studies comprising 953 patients who underwent SEPS placement met the inclusion criteria. The pooled rate of a successful outcome was 0.79 (95% CI 0.75-0.83). Frequency of delayed hematoma recurrence was 0.15 (95% CI 0.10-0.21). The pooled inpatient mortality rate was 0.02 (95% CI 0.01-0.03). Complications rates included 0.02 (95% CI 0.00-0.03) for any acute hemorrhage, 0.01 (95% CI 0.00-0.01) for acute hemorrhage requiring surgery, and 0.02 (95% CI 0.01-0.03) for seizure. SEPS placement is associated with a success rate of 79% and very low rates of acute hemorrhage and seizure. This data supports its use as a first-line management strategy, although prospective randomized studies are needed.

BACKGROUND: Subdural drain (SDD) and Subdural Evacuating Port System (SEPS) are bedside options for management of nonacute subdural hematomas (SDHs). These interventions have not been compared with each other. Our objective is to compare the need for second bedside procedure, need for craniotomy, complication rate, and other outcomes related to bedside drainage of SDH with SDD or SEPS. We hypothesized that SDD would be associated with superior outcomes to SEPS. METHODS: Database queries and direct patient chart reviews were used to gather patient data. t-Tests, Fisher exact tests, and proportional odds models were performed. RESULTS: Of 41 SDDs and 25 SEPS, baseline characteristics were similar except more isodense SDHs were present in SDD (P = 0.0312). SEPS was associated with significant risk of requiring a second bedside procedure (odds ratio, 3.2381; 99% confidence interval, 1.0345-10.1355) relative to SDD. Need for craniotomy did not differ between groups (12.1% SDD vs. 16% SEPS; P = 0.721). The complication rate was similar between groups (2.4% SDD vs. 12% SEPS; P = 0.1484). Symptom resolution, condition at latest follow-up, and posthospital disposition were similar between groups, but SEPS was associated with longer intensive care unit and total hospital length of stay (P = 0.02 and 0.04, respectively). CONCLUSIONS: SEPS was associated with higher risk for need of second bedside procedure and longer intensive care unit and hospital length of stay than SDD, although not increased need for craniotomy. Additional studies are needed to confirm our findings and determine if SDD may be more effective than SEPS for the treatment of nonacute SDH.

Chronic subdural hematoma (CSDH) is a relatively common condition encountered in a neurosurgical practice. There have been increased efforts in creating different treatment regimens for CSDH to improve patients' outcomes, including the addition of tissue plasminogen activator (tPA) in drains to reduce recurrences. Here, we present the first case report of the safe use of tPA in conjunction with an Integra Camino bolt for maximized drainage of CSDH with a successful neurological recovery and the complete resolution of the hematoma.
RESUMO
Chronic subdural hematoma (cSDH) is a common condition that disproportionately affects older patients. Given the greater risks of general anesthesia in this population, interest has turned towards less invasive surgical approaches such as the subdural evacuating port system (SEPS; Medtronic, Inc., Minneapolis, MN). There is a relative dearth of information about the outcomes following this procedure. Here, we present our institution's experience with SEPS and analyze factors associated with the outcomes. Using a prospectively maintained institutional database, we retrospectively identified all patients who presented with cSDH and received first line therapy with SEPS. Pre- and post-operative clinical and radiographic data was obtained from the electronic health record. Outcomes included success or failure, Modified Rankin Scale (mRS) at discharge, length of stay (LOS), and discharge disposition. A total of 126 patients met the inclusion criteria (36 females and 90 males; mean age of 71.6â¯years). None of the pre-procedural clinical or radiographic variables were associated with the likelihood of a successful outcome. Increasing age was associated with non-routine hospital discharge (pâ¯=â¯0.003), and lower presenting GCS was associated with longer hospital stay (pâ¯=â¯0.005). Greater thickness of the cSDH was associated with a lower likelihood of having a favorable outcome (mRSâ¯≥â¯3; pâ¯=â¯0.003). SEPS is an effective first-line therapy for cSDH. Variables previously reported to limit the effectiveness of the technique (presence of septations, mixed density collections) were not associated with treatment failure.

OBJECTIVE The aims of this study were to evaluate a multiyear experience with subdural evacuating port system (SEPS) placement for chronic subdural hematoma (cSDH) in the intensive care unit at a tertiary neurosurgical center and to compare SEPS placement with bur hole evacuation in the operating room. METHODS All cases of cSDH evacuation were captured over a 7-year period at a tertiary neurosurgical center within an integrated health care delivery system. The authors compared the performance characteristics of SEPS and bur hole placement with respect to recurrence rates, change in recurrence rates over time, complications, length of stay, discharge disposition, and mortality rates. RESULTS A total of 371 SEPS cases and 659 bur hole cases were performed (n = 1030). The use of bedside SEPS placement for cSDH treatment increased over the 7-year period, from 14% to 80% of cases. Reoperation within 6 months was higher for the SEPS (15.6%) than for bur hole drainage (9.1%) across the full 7-year period (p = 0.002). This observed overall difference was due to a higher rate of reoperation during the same hospitalization (7.0% for SEPS vs 3.2% for bur hole; p = 0.008). Over time, as the SEPS procedure became more common and modifications of the SEPS technique were introduced, the rate of in-hospital reoperation after SEPS decreased to 3.3% (p = 0.02 for trend), and the difference between SEPS and bur hole recurrence was no longer significant (p = 0.70). Complications were uncommon and were similar between the groups. CONCLUSIONS Overall performance characteristics of bedside SEPS and bur hole drainage in the operating room were similar. Modifications to the SEPS technique over time were associated with a reduced reoperation rate.

UNLABELLED: OBJECT.: The incidence of chronic subdural hematoma (CSDH) is expected to increase substantially over the next 25 years. Continuing refinement of techniques for surgical evacuation is essential for optimizing patient outcomes. A novel technique involving a hollow screw, which is threaded through a twist-drill hole in the cranium and then connected to a closed drainage system, has been increasing in popularity. The aim of this systematic review is to collate and analyze the published experience with this novel technique and to evaluate its efficacy in comparison with the other surgical treatment methods. METHODS: This systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and has been registered with the PROSPERO International Prospective Register of Systematic Reviews (registration number CRD42013003544). MEDLINE, Web of Knowledge, EMBASE, and the Cochrane Database of Systematic Reviews were searched for published series involving more than 10 patients treated with these new techniques. RESULTS: Nine eligible studies were found (6 case series and 3 case-control studies) comprising 796 patients treated with these new techniques. Pooled analysis showed a "success rate" of 77.6% (95% CI 74.6%-80.4%), recurrence rate of 22.4%, and in-hospital mortality of 1.4%. CONCLUSIONS: This systematic review adds further evidence to the pool of data assessing the safety and efficacy of the use of this novel, minimally invasive technique for the treatment for CSDH. Overall, twist-drill craniostomy with hollow screws appears to be safe and effective. Class I evidence is necessary to optimize the surgical management of patients with CSDH.
