Review Case Reports
Genetically confirmed CARASIL: A case report with a novel HTRA1 mutation and literature review.
Cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL) is an extremely rare monogenic autosomal disease associated with the HtrA serine protease 1 (HTRA 1) gene mutation. Recently, a few genetically confirmed CARASIL cases with novel HTRA1 mutations have been reported in countries other than Japan. ⋯ CARASIL is a rare autosomal recessive disease with an HTRA1 mutation. Familiarity with the early clinical and imaging features of CARASIL combined with a genetic test is key for its early diagnosis.

Review Comparative Study
Intracranial Tubular Retractor Systems: A Comparison and Review of the Literature of the BrainPath™, Vycor™, and METRx™ Tubular Retractors in the Management of Deep Brain Lesions.
In neurosurgery, parenchymal injury resulting from focal exertion of pressure on retracted tissue is a common complication associated with the use of plate and self-sustaining retractors to access deep intraparenchymal lesions. Tubular retractors, including Vycor, BrainPath, and METRx, were developed to reduce retraction injuries via radial dispersion of force. Our study seeks to compare these retraction systems and assess their respective indications, benefits, and associated complications. ⋯ This report is the first formal comparison of the BrainPath, Vycor, and METRx tubular retraction systems. We found that all 3 retractors were effective in accessing intraparenchymal lesions. Although we found that the retractor systems were used more commonly in different locations and for different diseases, there was no significant difference in complications or mortality among the 3 retractors.
