Controlled arachnoid opening to aid endoscopic trans-sphenoidal extrarachnoidal dissection of pituitary macroadenoma.

OBJECTIVES: The arachnoid often bulges prematurely during surgical excision of large pituitary tumors obscuring the deeper regions and crevices preventing total excision. Pushing the arachnoid may not be helpful and may tear it inadvertently and extensively leading to complications. We have described controlled arachnoid opening in large pituitary macroadenomas during the final stages of excision to gain access to the hidden portions and compared our results to the conventional technique. PATIENTS AND METHODS: Patients with pituitary macroadenoma of Hardy's III and KNOSP II in whom arachnoid had bulged prematurely were considered for study. They were grouped temporally. In first group (n = 12), the arachnoid was pushed to retrieve the tumor and in the second group (n = 10) it was punctured to aid resection. The extent of resection was assessed on postoperative scans, and complications in both groups, were noted. RESULTS: In the first group where arachnoid was pushed to retrieve tumor, Gross Total Resection (GTR) could be achieved in 5 patients. Inadvertent large arachnoid tear occurred in 3 patients of which, 2 developed CSF Rhinorrhoea. No patient had neurovascular injury.In the second group, GTR could be achieved in all without any added complications. CONCLUSION: Deliberate needle puncture and controlled drainage of CSF from arachnoid that bulges prematurely while endoscopic Transsphenoidal surgery for large pituitary tumors is a safe and effective method to gain access to the hidden portions of tumor to achieve GTR.

Radiation-induced intracranial rhabdomyosarcoma- A rare complication: Report of a case with literature review.

Radiation-induced sarcoma (RIS) of the central nervous system is an uncommon late complication of radiation therapy. We report a case of a 47-year-old male patient who underwent surgery followed by irradiation and chemotherapy with temozolomide for a frontal lobe gliosarcoma and presented 43 months later with a recurrent tumor in the same location with interval growth in the size of the lesion. Histology from surgical resection of the recurrent tumor revealed embryonal rhabdomyosarcoma (RMS). Adjacent brain parenchyma showed radiation-induced changes. There was no evidence of gliosarcoma at recurrence. In addition to the rarity of sarcomas arising following irradiation for glial tumors, this case represents one of the first reports of an intracerebral RMS arising in this setting.

Limited Invasive Protocol: Optimizing Diagnostic Modalities in Corticotropin Mediated Cushing Syndrome.

BACKGROUND: To limit the role of bilateral inferior petrosal sinus sampling (BIPSS) in distinguishing between Cushing disease (CD) and ectopic Cushing syndrome (ECS), recent reports have proposed a noninvasive approach based on a combination of biochemical testing and radiological imaging as an alternative to the conventional invasive strategy (CIS). However, this strategy requires further validation. The current study aimed to evaluate 2 limited invasive protocols (LIP-1 and LIP-2) in limiting the role of BIPSS while maintaining a diagnostic accuracy similar to that of CIS. METHODS: This was a single-center study conducted on individuals with corticotropin-dependent Cushing syndrome. The LIPs were based on performing high-dose dexamethasone suppression (>50% cut-off in first [LIP-1] and >80% in second [LIP-2]) and magnetic resonance imaging of the sella in all individuals and selective use of computed tomography of the chest and abdomen before BIPSS. These LIPs were evaluated for limiting the use of BIPSS, their accuracy, and cost in comparison to CIS. RESULTS: Of the 206 individuals, 114 (97 of CD and 21 of ECS) were eligible for the current study. Using LIP-1, LIP-2, and CIS, BIPSS could have been avoided in 62.3%, 35.9%, and 25.4% of individuals, respectively. The positive predictive value for CD using LIP-1 and LIP-2 was 98.9% and 100%, respectively. The cost per patient evaluated using LIP-1, LIP-2, and CIS was $602.21, $966.81, and $1107.78, respectively. CONCLUSION: LIPs represent an equally accurate, less invasive, and more cost-effective alternative to the CIS for distinguishing between CD and ECS.

Differential independent impact of the intraoperative use of navigation and angled endoscopes on the surgical outcome of endonasal endoscopy for pituitary tumors: a prospective study.

Despite widespread popularity of navigation and angled endoscopes in endonasal endoscopy, there are hardly few studies on their efficacy with the extent of resection or retreatment. This is probably the first study to assess the independent impact of these adjuncts among pituitary tumors. Patients with pituitary tumors undergoing endonasal endoscopy were prospectively studied for their demographics, clinico-radiological features, intraoperative use of navigation, and angled endoscopes, in relation to gross total resection (GTR), near total resection (NTR), endocrine remission, and retreatment. Pertinent statistical analyses were performed. Among a total of 139 patients, navigation and angled endoscopes could be used in 54 and 48 patients, respectively, depending upon their availability rather than chosen as per the case. There was no significant difference in baseline characteristics in relation to their use. The surgeon's perception of immediate benefit was noted among 51.9% while using navigation. The use of angled endoscopes towards the end of resection could help with additional tumor removal in 62.5% of patients. Overall, the use of navigation resulted in a significantly higher GTR (80.8% vs. 59.7%, OR 2.83, p = 0.01), a higher GTR/NTR (86.5% vs. 70.8%, OR 2.65, p = 0.04), and a lower retreatment rate (7.7% vs. 20.8%, OR 3.15, p = 0.05) than the others. In functioning tumors with cavernous sinus invasion, navigation had significantly increased remission rates (69.2% vs. 0%, p = 0.03). The use of angled endoscopes yielded a significantly higher GTR/NTR (91.7% vs. 70.6%, p = 0.04) and a lower retreatment rate (0% vs. 15.7%, p = 0.05) among only non-functioning adenomas. In multivariate analyses, the use of neuronavigation had a significant association with both GTR and retreatment rates (p values 0.005 and 0.02 respectively), independent of other confounding factors. The elective intraoperative use of navigation has a significant independent impact on the extent of resection and retreatment overall. While navigation results in better remission rates among functioning tumors with cavernous sinus invasion, angled endoscopy has a significant association with surgical outcomes in non-functioning tumors.

The collateral fallout of COVID19 lockdown on patients with head injury from north-west India.

BACKGROUND: The COVID19 lockdown has altered the dynamics of living. Its collateral fallout on head injury care has not been studied in detail, especially from low- and middle-income countries, possibly overwhelmed more than developed nations. Here, we analyze the effects of COVID19 restrictions on head injury patients in a high-volume Indian referral trauma center. METHODS: From the prospective trauma registry, clinico-epidemiological and radiological parameters of patients managed during 190 days before and 190 days during COVID19 phases were studied. As an indicator of care, the inpatient mortality of patients with severe HI was also compared with appropriate statistical analyses. RESULTS: Of the total 3372 patients, there were 83 head injury admissions per week before COVID19 restrictions, which decreased to 33 every week (60% drop) during the lock phases and stabilized at 46 per week during the unlock phases. COVID19 restrictions caused a significant increase in the proportion of patients arriving directly without resuscitation at peripheral centers and later than 6 h of injury. Though the most common mechanism was vehicular, a relative increase in the proportion of assaults was noted during COVID19. There was no change in the distribution of mild, moderate, and severe injuries. Despite a decrease in the percentage of patients with systemic illnesses, severe head injury mortality was significantly more during the lock phases than before COVID19 (59% vs. 47%, p = 0.02). CONCLUSIONS: COVID19 restrictions have amplified the already delayed admission among patients of head injury from north-west India. The severe head injury mortality was significantly greater during lock phases than before COVID19, highlighting the collateral fallout of lockdown. Pandemic control measures in the future should not ignore the concerns of trauma emergency care.

Head injury care in a low- and middle-income country tertiary trauma center: epidemiology, systemic lacunae, and possible leads.

BACKGROUND: Although head injury (HI) from low- and middle-income countries (LMIC) heavily contributes to the global disease burden, studies are disproportionately less from this part of the world. Knowing the different epidemiological characteristics from high-income nations can target appropriate prevention strategies. This study aims to provide a comprehensive overview of the clinico-epidemiological data of HI patients, focusing on the existing challenges with possible solutions from a developing nation's perspective. METHODS: This is a prospective, registry-based, observational study of HI in an Indian tertiary trauma-care center over 4 years. Various clinico-epidemiological parameters, risk factors, and imaging spectrum were analyzed in a multivariate model to identify the challenges faced by LMIC and discuss pragmatic solutions. RESULTS: The study included a large-volume cohort of 14,888 patients. Notably, half of these patients belonged to mild HI, despite most were referred (90.3%) cases. Only one-third (30.8%) had severe HI. Less than a third reached us within 6 h of injury. Road traffic accidents (RTA) accounted for most injuries (61.1%), especially in the young (70.9%). Higher age, males, RTA, helmet non-usage, drunken driving, systemic injuries, and specific imaging features had an independent association with injury severity. CONCLUSIONS: The study represents the much-needed, large-volume, epidemiological profile of HI from an LMIC, highlighting the suboptimal utilization of peripheral healthcare systems. Strengthening and integrating these facilities with the tertiary centers in a hub and enhanced spoke model, task sharing design, and efficient back-referrals promise effective neurotrauma care while avoiding overburden in the tertiary centers. Better implementation of road safety laws also has the potential to reduce the burden of HI.

Customising the surgical management for intraventricular meningiomas - 'one size doesn't fit all'.

BACKGROUND: Intraventricular meningiomas are uncommon and gross total resection is the recommended treatment. However, total resection may not always be possible, especially in locations in which the lesions are adherent to veins and neural structures. We share our experience with intraventricular meningiomas, focusing on the management strategies and outcomes. PATIENTS AND METHODS: We describe the data of 7 patients with intraventricular meningiomas operated at our institute over the last 9 years. Three patients had a third ventricular tumor of which two had lesions straddling across the foramen of Monro. The remaining 4 patients had trigonal mass. The clinico-radiological features, management strategies and outcomes have been elaborated with a mean follow-up of 57 months. RESULTS: The common clinical presentations were raised intracranial pressure symptoms, visual field defects and memory deficits. One patient had multiple meningiomas. Total excision was achieved in all except in 2 patients in whom the lesion straddled across the foramen of Monro with dense adhesions to veins and neural structures. Staged resection was required in one patient with a large trigonal mass. All patients had a low-grade lesion. The tumor recurred in one patient (post-pregnancy) after partial resection. All the patients improved neurologically, and none had added deficits. CONCLUSIONS: Gross total resection of intraventricular meningiomas although desirable may not be possible in certain cases in which the risks outweigh the benefits. These tumors often are of low histological grade and the treatment strategies should be individualized. Regular follow-up is warranted as these tumors may recur despite a low histological grade.

COVID-19: changing patterns among neurosurgical patients from North India, efficacy of repeat testing, and inpatient prevalence.

OBJECTIVE: COVID-19 has affected surgical practice globally. Treating neurosurgical patients with the restrictions imposed by the pandemic is challenging in institutions with shared patient areas. The present study was performed to assess the changing patterns of neurosurgical cases, the efficacy of repeated testing before surgery, and the prevalence of COVID-19 in asymptomatic neurosurgical inpatients. METHODS: Cases of non-trauma-related neurosurgical patients treated at the Postgraduate Institute of Medical Education and Research (PGIMER) before and during the COVID-19 pandemic were reviewed. During the pandemic, all patients underwent a nasopharyngeal swab reverse transcription-polymerase chain reaction test to detect COVID-19 at admission. Patients who needed immediate intervention were surgically treated following a single COVID-19 test, while stable patients who initially tested negative for COVID-19 were subjected to repeated testing at least 5 days after the first test and within 48 hours prior to the planned surgery. The COVID-19 positivity rate was compared with the local period prevalence. The number of patients who tested positive at the second test, following a negative first test, was used to determine the probable number of people who could have become infected during the surgical procedure without second testing. RESULTS: Of the total 1769 non-trauma-related neurosurgical patients included in this study, a mean of 337.2 patients underwent surgery per month before COVID-19, while a mean of 184.2 patients (54.6% of pre-COVID-19 capacity) underwent surgery per month during the pandemic period, when COVID-19 cases were on the rise in India. There was a significant increase in the proportion of patients undergoing surgery for a ruptured aneurysm, stroke, hydrocephalus, and cerebellar tumors, while the number of patients seeking surgery for chronic benign diseases declined. At the first COVID-19 test, 4 patients (0.48%) tested were found to have the disease, a proportion 3.7 times greater than that found in the local community. An additional 5 patients tested positive at the time of the second COVID-19 test, resulting in an overall inpatient period prevalence of 1%, in contrast to a 0.2% national cumulative caseload. It is possible that COVID-19 was prevented in approximately 67.4 people every month by using double testing. CONCLUSIONS: COVID-19 has changed the pattern of neurosurgical procedures, with acute cases dominating the practice. Despite the fact that the pandemic has not yet reached its peak in India, COVID-19 has been detected 3.7 times more often in asymptomatic neurosurgical inpatients than in the local community, even with single testing. Double testing displays an incremental value by disclosing COVID-19 overall in 1 in 100 inpatients and thus averting its spread through neurosurgical services.

Pendular See-Saw Nystagmus: A Rare Presenting Manifestation of Craniopharyngioma.

Pendular see-saw nystagmus is an extremely rare form of nystagmus characterised by cyclical movement of the eyes with a conjugate torsional component and a disjunctive vertical component. Intorsion and elevation of one eye is accompanied by simultaneous extorsion and depression of the contralateral eye. Most commonly it results from a suprasellar/parasellar mass compressing the meso-diencephalic region. Herein, we report a case of a 5-year-old girl who presented with pendular see-saw nystagmus secondary to a craniopharyngioma. The nystagmus resolved following excision of the lesion.

Modified unilateral approach for mid-third giant bifalcine meningiomas: resection using an oblique surgical trajectory and falx window.

BACKGROUND: Utilizing the shortest available trajectory is the norm for excision of meningiomas. However, such an approach for the mid-third/central falcine meningiomas risks the adjoining draining veins and eloquent cortex. A larger size and bilaterality of such tumors adds to the surgical challenge. Herein, we report the surgical nuances of a modified unilateral approach in patients operated for giant bilateral symmetrical mid-third falcine meningiomas. METHODS: Five such patients were operated. The clinico-radiologic data was studied at presentation and at the follow-up. The meningiomas were subclassified into those that were located in the anterior and posterior half of the central falx, and their surgical trajectory was chosen accordingly. The tumor was excised through an oblique anterior or a posterior trajectory instead of directly working over the major draining veins and eloquent brain. The falx was incised to create a surgical window and access the tumor on the contralateral side. RESULTS: Four patients had meningiomas in the anterior half and one in the posterior half of central falx. Simpson excision was grade II in four patients. One patient showed small residual tumor and underwent stereotactic radiosurgery. The overall mean follow-up of the patients was 9.2 months. All the patients had good clinical outcome. CONCLUSIONS: Giant bifalcine meningiomas can be safely resected through a unilateral approach. Falx opening serves as a window to remove the tumor from the contralateral side. An oblique trajectory rather than an end-on access to these tumors minimizes the risk of venous and cortical injury.

Has Outcome of Subarachnoid Hemorrhage Changed With Improvements in Neurosurgical Services?

Background and Purpose- Though reports suggest decreasing fatality rates of subarachnoid hemorrhage with time, trends in outcome are not reported much especially from developing countries. This study was to analyze changes in outcome across 2 decades and elucidate probable factors. Methods- Prospective databases during 1996 to 2015 were reviewed for neurological outcome at 3 months in relation to demographics, Hunt and Hess grade, Fisher grade, and definitive treatment; and compared between 2 decades, contrasted by establishment of intensive care unit with continuous monitoring and other advancements. Univariate and multivariate analyses were performed. Results- Of the total 2039 patients, 1035 were managed in the former and 1004 in the recent decades. Compared with the former decade, there is delayed age at presentation (46 versus 49 years, P<0.001), poorer Fisher grades (81% versus 87%, P<0.001), and more patients with Hunt and Hess grade 2 (24% versus 39%, P<0.001) in the recent decade. While all patients in databases of the former decade had undergone clipping, 6% in the recent decade underwent coiling. 11% in the recent decade could not undergo definitive treatment. Despite this, there was significantly higher overall favorable outcome (50% versus 60%; odds ratio, 1.5; P<0.001) in recent decade. Favorable outcome of surgical clipping per se improved significantly from 50% to 67% (odds ratio 2.0; P<0.001). Though the improvement was across subgroups, it was more marked among Hunt and Hess grade 3 and Fisher grades 3 and 4. In multivariate analyses, both overall outcome (adjusted odds ratio, 1.7; 95% CI, 1.4-2.1; P<0.001) and surgical outcome (adjusted odds ratio, 1.8; 95% CI, 1.5-2.2; P<0.001) were significantly better in recent decade, independent of known prognostic factors. Conclusions- This is probably the first report to show independent improvement in outcome of subarachnoid hemorrhage with betterment in neurosurgical services from developing country. Dedicated intensive care unit care and focused management protocols could be the likely causes for improvement. Resource-constrained institutions may target patients in Hunt and Hess grade 3 and Fisher grades 3 and 4 for optimal intensive care unit utilization.

Otogenic Cerebellar Abscess with Polymicrobial Anaerobic Infection in a Young Female- A Rare Presentation.

Brain abscess is a serious clinical condition caused by a localized collection of pus within the brain tissue. This typically occurs as a result of an infection that originates from a nearby area, such as an ear, sinus, or dental infection, or an infection in the bloodstream. Streptococcus and Staphylococcus species are the most common organisms implicated in brain abscesses. Apart from aerobic growth, cases of mixed infections of both aerobic and anaerobic organisms are also commonly reported in the literature. Herein we report a 23-year-old immunocompetent female with chronic otitis media who presented with cerebellar abscess where the aerobic growth was sterile and anaerobic culture revealed pure growth of dual anaerobes viz… Peptostreptococcus and Bacteroides thetaiotaomicron. This case highlights the importance of prompt diagnosis and management of polymicrobial anaerobic infection in cases of brain abscess.

68 Ga-Pentixafor PET/CT for In Vivo Imaging of CXCR4 Receptors in Glioma Demonstrating a Potential for Response Assessment to Radiochemotherapy: Preliminary Results.

PURPOSE: The aim of this study was to evaluate the diagnostic potential of 68 Ga-pentixafor PET/CT for in vivo CXCR4 receptors imaging in glioma and its possible role in response assessment to radiochemotherapy (R-CT). METHODS: Nineteen (12 men, 7 women) patients with glioblastoma multiforme (GBM) underwent 68 Ga-pentixafor PET/CT, contrast-enhanced MR, and MR spectroscopy. Patients were divided in to 2 groups, that is, group I was the presurgical (n = 9) group in which the scanning was done before surgery, and PET findings were correlated with CXCR4 receptors' density. The group II was the postsurgical (n = 10) group in which the scanning was done before and after R-CT and used for treatment response evaluation. The quantitative analysis of 68 Ga-pentixafor PET/CT evaluated the mean SUV max , SUV mean , SUV peak , and T/B values. MR spectroscopy data evaluated the ratios of tumor metabolites (choline, NAA, creatine). RESULTS: 68 Ga-Pentixafor uptake was noted in all (n = 19) the patients. In the group I, the mean SUV max , SUV mean , SUV peak , and T/B values were found to be 4.5 ± 1.6, 0.60 ± 0.26, 1.95 ± 0.8, and 6.9 ± 4.6, respectively. A significant correlation ( P < 0.005) was found between SUV mean and choline/NAA ratio. Immunohistochemistry performed in 7/9 showed CXCR4 receptors' positivity (intensity 3 + ; stained cells >50.0%). In the group II, the mean SUV max at baseline was 4.6 ± 2.1 and did not differ (4.4 ± 1.6) significantly from the value noted at post-R-CT follow-up PET/CT imaging. At 6 months' clinical follow-up, 4 patients showed stable disease. SUV max and T/B ratios at follow-up imaging were lower (3.70 ± 0.90, 2.64 ± 1.35) than the corresponding values (4.40 ± 2.8; 2.91 ± 0.93) noted at baseline. Six (6/10) patients showed disease progression, and the mean SUV max , and T/B ratio in these patients were significantly ( P < 0.05) higher than the corresponding values at baseline and also higher than that noted in the stable patients. CONCLUSIONS: 68 Ga-Pentixafor PET/CT can be used for in vivo mapping of CXCR4 receptors in GBM. The technique after validation in a large cohort of patients may have added diagnostic value for the early detection of GBM recurrence and for treatment response evaluation.

Effect of Peri-operative Blood Transfusion on Neurological Outcome Following Aneurysmal Subarachnoid Hemorrhage: A Prospective Observational Study.

BACKGROUND: Anemia is a common complication of aneurysmal subarachnoid hemorrhage and is associated with unfavorable outcomes. Whether the physiological benefits of transfusion for anemia surpass the risk of blood transfusion remains to be determined. OBJECTIVES: The primary outcome was to evaluate the impact of peri-operative blood transfusion on the long-term neurological outcome, assessed by Glasgow Outcome Scale Extended at 3 months. The secondary outcomes included the impact of transfusion on the short-term neurological outcome, assessed by Modified Rankin Score at discharge/7 days, and on the incidence of vasospasm, infarction, re-exploration, tracheostomy, and length of hospital stay. MATERIAL AND METHODS: This prospective observational study was conducted on 185 patients with aneurysmal subarachnoid hemorrhage undergoing clipping of the aneurysmal neck. In our study, blood transfusion was administered to keep the target Hb around 10 g/dL. RESULTS: Unfavorable long-term outcome was found in 27/97 (28%) of patients who received a blood transfusion as compared to 13/74 (18%) of patients who did not receive a transfusion (P = 0.116). Patients receiving transfusion had more chances of an unfavorable outcome at discharge/7 days as compared to those not transfused [44/103 (43%) versus 22/80 (27%)], P = 0.025. There were increased chances of vasospasm, infarction, re-exploration, tracheostomy, and increased length of hospital stay in patients receiving transfusion (P < 0.05). CONCLUSIONS: The use of blood transfusion in patients with aneurysmal subarachnoid hemorrhage was associated with increased neurological complications and hence an unfavorable short-term outcome. However, when used judiciously as per the clinical requirements, blood transfusion did not have a significant effect on long-term neurological outcome.

The Role of Serum Matrix Metalloproteinase-9 as a Predictor of Delayed Cerebral Ischemia in Patients with Aneurysmal Subarachnoid Hemorrhage.

Delayed cerebral ischemia (DCI) is one of the major causes of a poor neurological outcome following aneurysmal subarachnoid hemorrhage (aSAH). Several biomarkers, including matrix metalloproteinase-9 (MMP-9), have been evaluated to predict the development of DCI for timely management. This prospective cohort study was done on 98 patients with aSAH presenting within 72 h of the ictus. Serum samples were collected preoperatively, 7 days after ictus, 10 days after ictus, or when the patient developed DCI, whichever was earlier. The primary objective was to correlate the serum MMP-9 levels with the development of DCI. The secondary objectives were to correlate the serum MMP-9 levels with sonographic vasospasm and the neurological outcome. There was no correlation between the serum MMP-9 levels and the development of DCI (p = 0.37). Similarly, there was no correlation between the serum MMP-9 levels and the sonographic vasospasm (0.05) nor with the modified Rankin Scale (mRS) at discharge (p = 0.27), mRS at 3 months (p = 0.22), and Glasgow Outcome Scale Extended (GOSE) at 3 months (p = 0.15). Serum MMP-9 levels do not predict the development of DCI following aSAH.

Diagnostic Cerebral Angiography Through Distal Transradial Access: Early Experience with a Promising Access Route.

Background and Objective: Over the last few years, there has been considerable interest in the neurointervention community to use transradial approach for diagnostic and therapeutic neurointerventions. Distal radial approach has been postulated as an effective technique with reduced risk of hand ischemia. Our objective was to assess the safety and feasibility of distal transradial access (DTRA) to perform diagnostic cerebral angiography. Materials and Methods: A retrospective evaluation of 25 patients who were taken for DTRA through the anatomical snuff box from December 2021 to March 2022 was done. Results: Twenty-five diagnostic cerebral angiographies were attempted with DTRA in 25 patients (age, 23-70 years; mean age, 45.4 years; 10 (40%) females). The right distal radial artery mean diameter was 2.09 mm. The procedure was successful in 21 (84%) procedures. Failure was seen in four cases, with three being converted to the proximal transradial approach without any need for redraping and one was converted to the transfemoral approach. The reason for access conversion was a severe spasm in three cases and dissection in one case. Selective catheterization of the cranial vessels through a distal transradial approach was achieved in 92 (96.8%) of 95 vessels. No significant access site complications were seen in the study cohort. Conclusion: DTRA is a promising approach for diagnostic cerebral angiography. Interventionists should get accustomed to this approach by overcoming the initial learning curve.

Injury pattern of road traffic accident cases attending trauma centre of tertiary care hospital of North India.

Introduction: Injury is a significant global health burden and can result in mortality if not attended to on time. Trauma system refers to a collection of services provided by various super-specialties. According to the WHO-World Bank Report, RTA will rise from ninth place to the third biggest cause of mortality. Materials and Methods: The study was done at Advanced Trauma Centre (ATC) at PGIMER, a teaching hospital of north India. Study included area from most of the patient come for treatment (rural/urban) and injury patterns seen in these patients, which included mode of injury, type of injury, type of road accidents and location of injury. Results and Observations: In maximum cases, 60.2% (245) of the mode of injury was RTA. It was seen that the maximum number of patients, 44.4%, (115) had motorbike/scooter collisions with vehicles. In most patients, the type of injury seen was 35.9% (147) head, neck and back injuries, and in maximum cases, the location of the accident site was road/street 63.2%. Discussion: In our country, where the trauma delivery system is poorly developed, teaching hospitals have to bear the burden of treating many patients. No concept of emergency medicine or trauma care is in use, even in urban areas. As a result, teaching hospitals' emergency departments receive many referrals for emergency conditions.
