Academic productivity and career trajectory of international medical graduates in US neurosurgery residency programs.

OBJECTIVE: The objective of this study was to review and compare the research experiences and career outcomes of international medical graduates (IMGs) with those of US medical graduates (USMGs). METHODS: Neurosurgery graduates from 2018 to 2020 were evaluated on the basis of medical school, degree, residency program, publications before and during residency, postresidency fellowships, and career progression. Publications were further categorized by author order and type (laboratory, comprehensive clinical, or short communication). RESULTS: Of 550 neurosurgery graduates, 39 (7%) were IMGs, with the largest percentages from India (8/39, 21%) and in a residency position in Pennsylvania (5/39, 13%). Prior to residency, IMGs had a higher median number of all publications (4 vs 1, p < 0.001), first-author articles (2 vs 0, p < 0.001), comprehensive clinical articles (1 vs 0, p = 0.002), and short communication articles (1 vs 0, p < 0.001) than USMGs. Similarly, the median number of papers published by IMGs during residency was also higher compared with that of USMGs for all publications (20 vs 9, p = 0.004), laboratory articles (1 vs 0, p < 0.001), and short communication articles (4 vs 3, p = 0.04). The percentage of early academic appointments was higher for IMGs (25/39, 64%) than for USMGs (232/511, 45%) (p = 0.03). No significant difference was observed between the percentages of postresidency clinical fellowships completed by IMGs (28/39, 72%) and USMGs (302/511, 59%) (p = 0.15). No statistical significance was found between the ranking of neurosurgery residency programs attended by IMGs and USMGs (p = 0.65). CONCLUSIONS: The results indicate that IMGs often exhibit higher academic productivity than USMGs. Although there was no discernible difference in residency program rankings or postresidency fellowships completed, early academic appointments were more prevalent among IMGs.

Advanced Surgical Techniques for Dural Venous Sinus Repair: A Comprehensive Literature Review.

The dural venous sinus (DVS) is a thin-walled blood channel composed of dura mater that is susceptible to injury during common neurosurgical approaches. DVS injuries are highly underreported, which is reflected by a lack of literature on the topic. Neurosurgeons should be familiar with appropriate techniques to successfully repair an injured DVS and prevent associated complications. This study presents a literature review on the surgical techniques for DVS repair after DVS injury during common neurosurgical approaches. The databases PubMed and Scopus were queried using the terms "cranial sinuses," "superior sagittal sinus," "transverse sinuses," "injury," and "surgery." A total of 117 articles underwent full-text review and were analyzed for surgical approach, craniotomy, lesion location, lesion characteristics, and surgical repair techniques. A literature review was performed, and a comprehensive summary is presented. Data from publications describing DVS lacerations related to pathological conditions (eg, meningioma) were excluded. A total of 9 techniques aiding with bleeding control, hemostasis, and sinus repair and reconstruction were identified, including compression, hemostatic agents, bipolar cautery, dural tenting and tack-up suturing, dural flap, direct suturing, autologous patch, venous bypass, and ligation. The advantages and drawbacks of each technique are described. Multiple options to treat DVS injuries are available to the neurosurgeon. Treatment type is based on anatomic location, complexity of the laceration, cardiovascular status, the presence of air embolism, and the dexterity and experience of the surgeon.

Competitive neurosurgery residency programs: Predictors of matching outcome and research productivity.

OBJECTIVE: The aim of this study was to provide a comprehensive assessment of preresidency research and school as predictors of competitive neurosurgery matching and to assess for any correlations between preresidency and intraresidency research productivity. METHODS: Individuals who graduated from US neurosurgery programs from 2018 through 2020 were assessed for medical school, degree (MD, DO, or PhD), preresidency versus intraresidency publications, author order, article type, and neurosurgery matching outcomes. RESULTS: Medical school ranking (top 50) and the number of published papers (≥3) before intern year were predictors for matching to a top-25 residency program after adjusting for other covariates (p < 0.001, p = 0.002, respectively). On average, individuals who published more papers before residency published more papers during residency. For the comprehensive clinical papers category, there was a significant difference between individuals from the top 25 residency programs and others, with a stronger correlation between the number of preresidency publications and intraresidency publications for neurosurgeons who attended a top-25 residency program (r = 0.378 and r = 0.179, respectively; p = 0.02). CONCLUSION: Medical school ranking and research productivity as measured by the number of published papers were independently associated with matching to the top 25 residency programs. In addition, high research productivity in the preresidency years was associated with continued productivity during residency, especially in the category of comprehensive clinical papers.

Academically Inclined: Predictors of Early Career Trajectory and Avenues for Early Intervention Among Neurosurgery Trainees.

BACKGROUND: The relationship of academic activities before and during neurosurgery residency with fellowship or career outcomes has not been studied completely. OBJECTIVE: To assess possible predictors of fellowship and career outcomes among neurosurgery residents. METHODS: US neurosurgery graduates (2018-2020) were assessed retrospectively for peer-reviewed citations of preresidency vs intraresidency publications, author order, and article type. Additional parameters included medical school, residency program, degree (MD vs DO; PhD), postgraduate fellowship, and academic employment. RESULTS: Of 547 neurosurgeons, 334 (61.1%) entered fellowships. Fellowship training was significantly associated with medical school rank and first-author publications. Individuals from medical schools ranked 1 to 50 were 1.6 times more likely to become postgraduate fellows than individuals from medical schools ranked 51 to 92 (odds ratio [OR], 1.63 [95% CI 1.04-2.56]; P = .03). Residents with ≥2 first-author publications were almost twice as likely to complete a fellowship as individuals with <2 first-author publications (OR, 1.91 [95% CI 1.21-3.03]; P = .006). Among 522 graduates with employment data available, academic employment obtained by 257 (49.2%) was significantly associated with fellowship training and all publication-specific variables. Fellowship-trained graduates were twice as likely to pursue academic careers (OR, 1.99 [95% CI 1.34-2.96]; P < .001) as were individuals with ≥3 first-author publications ( P < .001), ≥2 laboratory publications ( P = .04), or ≥9 clinical publications ( P < .001). CONCLUSION: Research productivity, medical school rank, and fellowships are independently associated with academic career outcomes of neurosurgeons. Academically inclined residents may benefit from early access to mentorship, sponsorship, and publishing opportunities.

Management of basilar fenestration aneurysms: a systematic review with an illustrative case report.

BACKGROUND: Basilar artery (BA) fenestration aneurysm (BAFA) is a rare phenomenon commonly accompanying other aneurysms. Treatment is challenging, and few cases have been reported. This review investigated the management outcomes of BAFAs. METHODS: Publication databases were searched to identify studies evaluating outcomes of endovascular treatment (EVT) and microsurgical treatment of BAFAs from inception through 2021. Outcomes (clinical, angiographic, postoperative complications, and retreatment rates) were collected and analyzed. The authors present their case of a patient treated for a BAFA. RESULTS: Including the authors' case, 184 patients with 209 BAFAs were reported in 68 studies. Most patients (130/175; 74.3%) presented with ruptured aneurysms, most commonly involving the proximal segment of the BA. Most BAFAs were small (52/103, 50.5%) and saccular (119/143, 83.2%). Most patients underwent EVT (143/184, 77.7%); the rest underwent microsurgery. Postoperative complications after EVT occurred in 10 (8.3%) of 120 patients, with 4 of the 10 experiencing strokes. At clinical follow-up, most EVT patients (74/86, 86.0%) showed good outcomes; 3.9% (2/51) had died. Most aneurysms managed with EVT (56/73, 76.7%) showed complete occlusion at follow-up; 7.3% (8/109) were retreated. Postoperative complications occurred in 62.2% (23/37) of microsurgical patients; 5 (21.7%) of the 23 experienced strokes. All patients showed good clinical outcomes at follow-up. Most aneurysms (22/28, 78.6%) treated microsurgically showed complete occlusion at angiographic follow-up, with no retreatment required. CONCLUSION: BAFAs are often symptomatic; thus, treatment is challenging. By the 2000s, treatment had moved from microsurgical to endovascular modalities, with good clinical and angiographic outcomes.
