ABSTRACT

Vestibular schwannomas (VS) are benign intracranial tumors posing significant management challenges. This study aims to compare the outcomes of stereotactic radiosurgery (SRS) and watchful waiting (WW) in the management of newly diagnosed VS, integrating findings from both retrospective and the pioneering V-REX prospective trial. Adhering to PRISMA guidelines, a systematic review was conducted using MEDLINE, Embase, and Cochrane databases. Studies directly comparing SRS with WW for newly diagnosed VS were included. Primary outcomes focused on hearing preservation assessed through the AAO-HNS or Gardner-Robertson hearing classification scales and tumor progression, with secondary outcomes focusing on neurological symptoms, and the need for further treatment. Thirteen studies encompassing 1,635 patients (WW: 891; SRS: 744) were included.While no significant difference was found in serviceable hearing loss at last follow-up (RR = 1.51, [95%CI: 0.98, 2.32], p = 0.06), significant differences favoring WW were observed in pure tone audiometry (PTA) (MD = -13.51 [95%CI: -22.66, -4.37], p = 0.004) and word recognition score (WRS) (MD = 20.48 [95%CI: 9.72, 31.25], p = 0.0002). Analysis of tumor progression indicated no overall significant difference in risk between SRS and WW (RR = 0.40, [95%CI 0.07, 2.40], p = 0.32), but subgroup analysis suggested a lower risk with SRS in certain contexts. The need for further treatments favored SRS (RR = 0.24, [95%CI: 0.07, 0.74], p = 0.007). No significant differences were found in tinnitus and imbalance between the two groups. This comprehensive analysis suggests no marked difference in functional hearing preservation between SRS and WW in managing VS. However, untreated tumors commonly necessitate additional interventions. These findings highlight the need for individualized treatment decisions and underscore the importance of continued monitoring. The study advocates for further prospective trials to refine management strategies for VS.

ABSTRACT

BACKGROUND: Traditionally, patients undergoing craniotomy were subject to extended hospital stays for intensive monitoring and management of potential complications. However, with the evolution of surgical methods, anesthesia, and postoperative protocols, the feasibility and interest in same-day discharge (SDD) are growing. This study aimed to evaluate whether same-day discharge is a safe and feasible approach in craniotomy through a meta-analysis of the available literature. METHODS: Following PRISMA guidelines, a comprehensive search was conducted across Medline, Embase, Cochrane, and Web of Science databases from inception to December 2023. Eligible studies comprised reports in English with a minimum of 4 patients who underwent craniotomies and were discharged with same-day discharge, whether single-arm or comparative with normal discharge. Single proportion analysis with 95 % confidence interval (CI) was used to pool the studies and Odds Ratio (OR) with 95 % CI was used to measure effects in comparative analysis. A random-effects model was adopted. Endpoints included success and failure of pre-planned same-day discharge, and postoperative complications throughout the hospital stay (until discharge), these complications were further categorized into major and minor complications. Also, need for reoperation, readmission within 24 h, readmission after 24 h, and mortality. RESULTS: Seven observational studies were included. Five studies were included in the single-arm analysis, comprising data from 715 patients. Four studies comprising 731 patients were included in the comparative analysis, of whom 233 were discharged on SDD, and 498 were discharged normally. The analysis revealed a success rate of 88 % (95 % CI, 83 %-94 %), readmission to the hospital within the initial 24 h rate of 2 % (95 % CI, 1 %-2 %), readmission after 24 h rate of 1 % (95 % CI, 0 %-2 %;), total postoperative complications until discharge rate of 2 % (95 % CI, 1 %-4 %), major complications rate of 0 % (95 % CI, 0 %-0 %), minor complications rate of 2 % (95 % CI, 1 %-4 %), and mortality rate of 0 % (95 % CI, 0 %-0 %). Comparative analysis for complications and mortality showed no difference between both approaches. CONCLUSION: This systematic review and meta-analysis identified that same-day discharge in craniotomy for selected patients, as well as for tumor resection craniotomies, is highly feasible and safe, with a high success rate, low failure, and reoperation rates. Moreover, for selected patients, no evidence of harm in same-day discharge was identified when compared with normal discharge. Consequently, same-day discharge may be considered a viable option, provided appropriate selection criteria are employed.

ABSTRACT

PURPOSE: Persistent Spinal Pain Syndrome type 2 (PSPS-T2) poses a significant clinical challenge, demanding innovative therapeutic interventions. The integration of Spinal Cord Stimulation (SCS) and Dorsal Root Ganglion Stimulation (DRG-S) is emerging as a potent synergistic strategy for comprehensive pain management. This single patient-blind proof of concept (POC) trial explores the efficacy and synergistic potential of combined SCS and DRG-S in a patient with refractory PSPS-T2. METHODS: A 45-year-old male with intractable PSPS-T2 underwent a unique, methodically structured study, involving three treatment phases: Phase A with SCS alone, Phase B with DRG-S alone, and Phase C The patient, blinded to the treatment modalities, provided pain assessments using the Visual Analogue Scale (VAS) and Douleur Neuropathique 4 Questions (DN4) conducted by clinical investigators at each phase. Baseline pain scores were ten and nine, respectively. RESULTS: Distinct responses were noted across the phases. Phase A demonstrated moderate pain relief, while Phase B offered further pain intensity reduction. However, Phase C, combining both strategies, yielded the most significant improvement, remarkably enhancing the patient's quality of life and functional capacity. CONCLUSION: This POC trial underscores the synergistic potential of SCS and DRG-S in managing complex cases of PSPS-T2, suggesting a paradigm shift towards integrated neuromodulation strategies for enhanced pain control. The development of dual intent implantable pulse generators (IPGs) capable of offering combination therapy simultaneously might be effective for pain management in select cases. The significant pain reduction and functional improvement observed advocate for further research in dual neuromodulation therapies. TRIAL REGISTRATION NUMBER: IRB 20190536.

ABSTRACT

BACKGROUND: Resting-state electroencephalography (rsEEG) is usually obtained to assess seizures in comatose patients with traumatic brain injury (TBI). We aim to investigate rsEEG measures and their prediction of early recovery of consciousness in patients with TBI. METHODS: This is a retrospective study of comatose patients with TBI who were admitted to a trauma center (October 2013 to January 2022). Demographics, basic clinical data, imaging characteristics, and EEGs were collected. We calculated the following using 10-min rsEEGs: power spectral density, permutation entropy (complexity measure), weighted symbolic mutual information (wSMI, global information sharing measure), Kolmogorov complexity (Kolcom, complexity measure), and heart-evoked potentials (the averaged EEG signal relative to the corresponding QRS complex on electrocardiography). We evaluated the prediction of consciousness recovery before hospital discharge using clinical, imaging, and rsEEG data via a support vector machine. RESULTS: We studied 113 of 134 (84%) patients with rsEEGs. A total of 73 (65%) patients recovered consciousness before discharge. Patients who recovered consciousness were younger (40 vs. 50 years, p = 0.01). Patients who recovered also had higher Kolcom (U = 1688, p = 0.01), increased beta power (U = 1,652 p = 0.003) with higher variability across channels (U = 1534, p = 0.034) and epochs (U = 1711, p = 0.004), lower delta power (U = 981, p = 0.04), and higher connectivity across time and channels as measured by wSMI in the theta band (U = 1636, p = 0.026; U = 1639, p = 0.024) than those who did not recover. The area under the receiver operating characteristic curve for rsEEG was higher than that for clinical data (using age, motor response, pupil reactivity) and higher than that for the Marshall computed tomography classification (0.69 vs. 0.66 vs. 0.56, respectively; p < 0.001). CONCLUSIONS: We describe the rsEEG signature in recovery of consciousness prior to discharge in comatose patients with TBI. rsEEG measures performed modestly better than the clinical and imaging data in predicting recovery.

ABSTRACT

Cancer-related pain is a common and debilitating condition that can significantly affect the quality of life of patients. Opioids, NSAIDs, and antidepressants are among the first-line therapies, but their efficacy is limited or their use can be restricted due to serious side effects. Neuromodulation and lesioning techniques have also proven to be a valuable instrument for managing refractory pain. For patients who have exhausted all standard treatment options, hypophysectomy may be an effective alternative treatment. We conducted a comprehensive systematic review of the available literature on PubMed and Scielo databases on using hypophysectomy to treat refractory cancer-related pain. Data extraction from included studies included study design, treatment model, number of treated patients, sex, age, Karnofsky Performance Status (KPS) score, primary cancer site, lead time from diagnosis to treatment, alcohol injection volume, treatment data, and clinical outcomes. Statistical analysis was reported using counts (N, %) and means (range). The study included data from 735 patients from 24 papers treated with hypophysectomy for refractory cancer-related pain. 329 cancer-related pain patients were treated with NALP, 216 with TSS, 66 with RF, 55 with Y90 brachytherapy, 51 with Gamma Knife radiosurgery (GK), and 18 with cryoablation. The median age was 58.5 years. The average follow-up time was 8.97 months. Good pain relief was observed in 557 out of 735 patients, with complete pain relief in 108 out of 268 patients. Pain improvement onset was observed 24 h after TSS, a few days after NALP or cryoablation, and a few days to 4 weeks after GK. Complications varied among treatment modalities, with diabetes insipidus (DI) being the most common complication. Although mostly forgotten in modern neurosurgical practice, hypophysectomy is an attractive option for treating refractory cancer-related pain after failure of traditional therapies. Radiosurgery is a promising treatment modality due to its high success rate and reduced risk of complications.

ABSTRACT

Background Resting-state electroencephalogram (rsEEG) is usually obtained to assess seizures in comatose patients with traumatic brain injury (TBI) patients. We aim to investigate rsEEG measures and their prediction of early recovery of consciousness in comatose TBI patients. Methods This is a retrospective study of comatose TBI patients who were admitted to a level-1 trauma center (10/2013-1/2022). Demographics, basic clinical data, imaging characteristics, and EEG data were collected. We calculated using 10-minute rsEEGs: power spectral density (PSD), permutation entropy (PE - complexity measure), weighted symbolic-mutual-information (wSMI - global information sharing measure), Kolmogorov complexity (Kolcom - complexity measure), and heart-evoked potentials (HEP - the averaged EEG signal relative to the corresponding QRS complex on electrocardiogram). We evaluated the prediction of consciousness recovery before hospital discharge using clinical, imaging, rsEEG data via Support Vector Machine with a linear kernel (SVM). Results We studied 113 (out of 134, 84%) patients with rsEEGs. A total of 73 (65%) patients recovered consciousness before discharge. Patients who recovered consciousness were younger (40 vs. 50, p .01). Patients who recovered consciousness had higher Kolcom (U = 1688, p = 0.01,), increased beta power (U = 1652 p = 0.003), with higher variability across channels ( U = 1534, p = 0.034), and epochs (U = 1711, p = 0.004), lower delta power (U = 981, p = 0.04) and showed higher connectivity across time and channels as measured by wSMI in the theta band (U = 1636, p = .026, U = 1639, p = 0.024) than those who didn't recover. The ROC-AUC improved from 0.66 (using age, motor response, pupils' reactivity, and CT Marshall classification) to 0.69 (p < 0.001) when adding rsEEG measures. Conclusion We describe the rsEEG EEG signature in recovery of consciousness prior to discharge in comatose TBI patients. Resting-state EEG measures improved prediction beyond the clinical and imaging data.

ABSTRACT

BACKGROUND: Spinal cord stimulation (SCS) is a cost-effective option for treating refractory persistent spinal pain syndrome type-2 (PSPS-2). For patients with extensive spine instrumentation including the thoraco-lumbar junction, percutaneous placement of SCS leads is usually not an option being paddle leads typically implanted anterograde. Paddle lead placement will be particularly challenging in more complex cases when the instrumentation covers the targeted level. To overcome this barrier, we studied using a retrograde approach to reach the sweet spot, facilitate the placement, and reduce associated risks. OBJECTIVES: To study the use of retrograde SCS paddle as a placement method to optimize the spinal cord target and reduce the risks of conventional placement in complex cases. STUDY DESIGN: Case series and technical note. METHODS: We present three cases of thoracic retrograde SCS paddle lead placement cases, detailing patient selection, operative technique, and outcome. All the cases had extensive instrumentation to the thoraco-lumbar spine, and one had additional spinal canal stenosis. The surgical procedure entailed a retrograde midthoracic inter-laminar approach, flavectomy, and caudal placement of the paddle lead with intraoperative neurophysiologic monitoring (IONM) guidance for functional midline determination. RESULTS: All the cases had a successful lead placement over the sweet spot without complications. The same approach was used to decompress a focal spinal stenosis in one case. One case had significantly improved pain and hence underwent a pulse generator implant. The other cases had non-satisfactory pain control and were explanted. LIMITATIONS: These case description could guide technical procedural steps, however, a larger number of such cases would be needed to describe further technical nuances. CONCLUSIONS: We demonstrated that placing SCS paddle leads via retrograde midthoracic approach with IONM guidance is safe. This procedure should be an option for SCS paddle implants in patients with posterior spinal fusion encompassing the intended targeted spinal stimulation level.

ABSTRACT

Traumatic brain injury (TBI) poses significant challenges for assessing fitness-to-drive (FTD) and determining the appropriate timing for return-to-driving (RTD) in civilian adults. This systematic review and meta-analysis protocol is designed to offer a comprehensive assessment of RTD timelines post-TBI, examining the effects of injury severity as well as demographic and clinical factors that influence driving capabilities. In response to gaps identified in previous literature-namely, the absence of recent systematic search strategies and thorough quality assessments-this study employs rigorous methodologies for literature search, data extraction, and evaluation of study quality. Our approach aims to provide reliable estimates and detailed analyses of subgroups within the TBI population. The findings aim to support clinical decision-making, inform RTD readiness, and potentially impact policy and driving assessment protocols. Ultimately, this review seeks to contribute to public safety measures, reduce traffic-related harm, and improve life outcomes for individuals recovering from TBI, thereby filling a vital research niche in neurotrauma rehabilitation.

ABSTRACT

Robotic assistance in stereoelectroencephalography (SEEG) holds promising potential for enhancing accuracy, efficiency, and safety during electrode placement and surgical procedures. This systematic review and meta-analysis, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and International Prospective Register of Systematic Reviews (PROSPERO) registration, delves into the latest advancements and implications of robotic systems in SEEG, while meticulously evaluating outcomes and safety measures. Among 855 patients suffering from medication-refractory epilepsy who underwent SEEG in 29 studies, averaging 24.6 years in age, the most prevalent robots employed were robotic surgical assistant (ROSA) (450 patients), Neuromate (207), Sinovation (140), and ISys1 (58). A total of 8,184 electrodes were successfully implanted, with an average operative time of 157.2 minutes per procedure and 15.1 minutes per electrode, resulting in an overall mean operative time of 157.7 minutes across all studies. Notably, the mean target point error (TPE) stood at 2.13 mm, the mean entry point error (EPE) at 1.48 mm, and postoperative complications occurred in 7.69% of robotically assisted (RA) SEEG cases (60), with 85% of these complications being asymptomatic. This comprehensive analysis underscores the safety and efficacy of RA-SEEG in patients with medication-refractory epilepsy, characterized by low complication rates, reduced operative time, and precise electrode placement, supporting its widespread adoption in clinical practice, with no discernible differences noted among the various robotic systems.

ABSTRACT

PURPOSE OF REVIEW: High-cervical spinal cord stimulation can alter cortical activity and cerebral metabolism. These effects are potentially beneficial for disorders of consciousness. A better understanding of the effects of clinical application of stimulation is needed. We aimed to evaluate the existing literature to determine the state of available knowledge. We performed a literature review of clinical studies assessing cervical spinal cord epidural stimulation for disorders of consciousness. Only peer-reviewed articles reporting preoperative and postoperative clinical status were included. RECENT FINDINGS: Nineteen studies were included. A total of 532 cases were reported, and 255 patients were considered responsive (47.9%). Considering only studies published after the definition of minimally conscious state (MCS) as an entity, 402 individuals in unresponsive wakefulness syndrome (UWS) and 113 in MCS were reported. Responsiveness to SCS was reported in 170 UWS patients (42.3%) and in 78 MCS cases (69.0%), although the criteria for responsiveness and outcome measures varied among publications. SUMMARY: Cervical SCS yielded encouraging results in patients with disorders of consciousness and seems to be more effective in MCS. More extensive investigation is needed to understand its potential role in clinical practice.

ABSTRACT

BACKGROUND AND OBJECTIVES: Bedside procedures are often helpful for neurosurgical patients, especially in neurocritical care. Portable drills with technological advancements may bring more safety and efficiency to the bedside. In this study, we compared the safety and efficiency of a new cordless electric drill with smart autostop ("HD"-Hubly Cranial Drill, Hubly Surgical) with those of a well-established standard traditional electrical neurosurgical perforator ("ST"). METHODS: A cadaveric study was conducted using both drills to perform several burr holes in the fronto-temporo-parietal region of the skull. An evaluation was performed on the number of dura plunges, and complete burr hole success rates were compared. RESULTS: A total of 174 craniotomies using the HD and 36 burr holes using the ST perforator were performed. Despite significantly exceeding intended drill bit tolerance by multiple uses of a single-use disposable HD, autostop engaged in 100% of the 174 craniotomies and before violating dura in 99.4% of the 174 craniotomies, with the single dura penetration occurring on craniotomy no. 128 after the single-use drill bit had significantly dulled beyond its single-use tolerance. Autostop engaged before dura penetration for 100% of the 36 burr holes drilled with the ST perforator ( P = .610). All the perforations were complete using the HD after resuming drilling. An autostop mechanism in a cranial drill is not commonly available for portable bedside perforators. In the operating room, most use a mechanical method to stop the rotation after losing bone resistance. This new drill uses an electrical mechanism (smart autostop) to stop drilling, making it a single-use cranial drill with advanced features for safety and efficiency at the bedside. CONCLUSION: There was no difference in the safety and efficacy of the new cordless electric drill with smart autostop when performing craniotomies compared with a traditional well-established electric cranial perforator with mechanical autostop on a cadaveric model.

ABSTRACT

Gunshot head injuries are increasingly prevalent in the urban setting and carry complex technical and clinical decision-making challenges to practicing neurosurgeons. Here, we present a unique case of a patient who suffered a gunshot injury and presented to the emergency department with an intraventricular bullet lodgment without significant neurological deficits. The patient was rushed to the operating room to remove the bullet after neuroimaging demonstrated its migration inside the ventricular system. The patient showed a favorable outcome postoperatively. This case report highlights the importance of prompt diagnosis and tailored management strategies in cases of intraventricular bullet lodgment.

ABSTRACT

Sacral stimulation is a well-established therapy for urologic neuromodulation. After the advent of dorsal root ganglion (DRG) stimulation, pain surgeons have started to reach this target mostly for pelvic and sacral pain. For those without good surgical experience, sacral foramen puncture, especially S3 and S4, can be a challenge, due to its entry angle and limited C-arm image resolution. In this report, we describe a new technique to utilize sacral navigation using the O-arm approach to guide DRG stimulation implants. We discuss a case of a 53-year-old male patient with refractory coccygodynia, who underwent sacral DRG implantation using neuronavigation. Punctures could be done without the need for multiple attempts to reach the foramen in this patient.

ABSTRACT

Spinal epidural abscess is a relatively infrequent surgical indication, but it may be neurologically compromising. The most frequent pathogen is Staphylococcus aureus, present in two-thirds of the cases. Enterococcus faecalis is part of the intestinal flora and is uncommon in this condition. Colorectal cancer is reported to be a cause of hematogenic translocation and distant infection. We present a case of an 82-year-old patient admitted for acute low back pain with increased inflammatory markers and negative blood cultures. An MRI revealed an epidural lumbar abscess with adjacent spondylitis. After surgical treatment, E. faecalis was identified, and antibiotics were adjusted accordingly. A colonoscopy revealed colon cancer. This is the first case in the literature of a spinal epidural abscess by E. faecalis as the first manifestation of a newly diagnosed colorectal cancer. When facing a spinal infection caused by atypical intestinal bacteria and no other clear sources, a colonoscopy should be considered.

ABSTRACT

Ancient schwannoma is an uncommon variant of schwannoma. While many reports have presented defining histologic and clinical features of ancient schwannoma, there are only a very few cases in the literature, to our knowledge, of ancient schwannoma presenting at the cauda equina. The current report of ancient schwannoma presenting at the cauda equina adds to the literature and discusses the identification of specific histologic characteristics, the role of conservative medical management, surgical resection, and prognostication in this select subset of patients.

ABSTRACT

The emergency room management of a patient with external signs of cranial trauma and imaging showing brain hemorrhage can be dangerously misleading. This case of a patient with glioblastoma could only be timely diagnosed because of cautious evaluation of imaging findings. A 60-year-old patient presented to the emergency room after being found down with external signs of cranial trauma and a reduced level of consciousness. Computed tomography revealed a right frontal polar cortical hemorrhage of around 12 mm diameter with no perilesional edema or contrast enhancement. Likewise, the MRI showed no contrast enhancement. Before the scheduled MRI follow-up was performed the patient became symptomatic leading to an earlier repeat that showed massive progression. She underwent surgical resection that revealed the lesion to be an aggressive glioblastoma. High suspicion of an underlying neoplastic lesion in atypical brain hemorrhage in trauma patients is paramount. Short MRI follow-up is recommended as soon as the hematoma resorbs to prevent delays with potential impact or patient outcome.

ABSTRACT

Background: Burr hole evacuation is a well-established treatment for symptomatic cases with chronic subdural hematoma (cSDH). Routinely postoperative catheter is left in the subdural space to drain the residual blood. Drainage obstruction is commonly seen, and it can be related to suboptimal treatment. Methods: Two groups of patients submitted to cSDH surgery were evaluated in a retrospective non-randomized trial, one group that had conventional subdural drainage (CD group, n â€‹= â€‹20) and another group that used an anti-thrombotic catheter (AT group, n â€‹= â€‹14). We compared the obstruction rate, amount of drainage and complications. Statistical analyses were done using SPSS (v.28.0). Results: For AT and CD groups respectively (median â€‹± â€‹IQR), the age was 68.23 â€‹± â€‹26.0 and 70.94 â€‹± â€‹21.5 (p â€‹> â€‹0.05); preoperative hematoma width was 18.3 â€‹± â€‹11.0 â€‹mm and 20.7 â€‹± â€‹11.7 â€‹mm and midline shift was 13.0 â€‹± â€‹9.2 and 5.2 â€‹± â€‹8.0 â€‹mm (p â€‹= â€‹0.49). Postoperative hematoma width was 12.7 â€‹± â€‹9.2 â€‹mm and 10.8 â€‹± â€‹9.0 â€‹mm (p â€‹< â€‹0.001 intra-groups compared to preoperative) and MLS was 5.2 â€‹± â€‹8.0 â€‹mm and 1.5 â€‹± â€‹4.3 â€‹mm (p â€‹< â€‹0.05 intra-groups). There were no complications related to the procedure including infection, bleed worsening and edema. No proximal obstruction was observed on the AT, but 8/20 (40%) presented proximal obstruction on the CD group (p â€‹= â€‹0.006). Daily drainage rates and length of drainage were higher in AT compared to CD: 4.0 â€‹± â€‹1.25 days vs. 3.0 â€‹± â€‹1.0 days (p â€‹< â€‹0.001) and 69.86 â€‹± â€‹106.54 vs. 35.00 â€‹± â€‹59.67 â€‹mL/day (p â€‹= â€‹0.074). Symptomatic recurrence demanding surgery occurred in two patients of CD group (10%) and none in AT group (p â€‹= â€‹0.230), after adjusting for MMA embolization, there was still no difference between groups (p â€‹= â€‹0.121). Conclusion: The anti-thrombotic catheter for cSDH drainage presented significant less proximal obstruction than the conventional one and higher daily drainage rates. Both methods demonstrated to safe and effective for draining cSDH.

ABSTRACT

Fahr syndrome, or bilateral striatopallidodentate calcinosis, is a rare syndrome that can confound interpretation of traumatic brain injury seen on computed tomography of the head (CTH). Understanding that this syndrome presents with diffuse calcified lesions will assist clinicians unfamiliar with Fahr syndrome when evaluating diffuse hyperdensities seen on CTH in the setting of trauma between traumatic acute blood versus calcification. We present a unique image that demonstrates how a traumatic brain injury patient can present with traumatic acute hemorrhage and Fahr syndrome. We highlight 2 methods within the CTH images that can be used to assist in these diagnoses, which will better inform neurosurgeons and other clinicians when encountering this unique and rare presentation for the first time.

ABSTRACT

Autosomal dominant polycystic kidney disease (ADPKD) is a connective tissue disease with vascular abnormalities involving multiple organs. The prevalence of ADPKD associated with a spontaneous subdural hematoma (SDH) is very low, with less than 10 cases reported in the literature to date. Symptomatic chronic SDH is classically treated with a twist drill, burr holes, or craniotomy. Recently, middle meningeal artery (MMA) embolization has emerged as an ancillary modality. We present the first case in the literature of a bilateral SDH in a young ADPKD patient successfully managed with MMA embolization. Moreover, we discuss the role of different treatment modalities on this subset of patients.
