During 12 years of follow-up, there was no survival difference between patients who underwent open or endovascular abdominal aortic aneurysm repair, despite a continuously increasing number of reinterventions in the endovascular repair group. Endograft durability and the need for continued endograft surveillance remain key issues.
The objective of the study was the determination of the intra- and interobserver agreement of three magnetic resonance imaging (MRI) criteria for reparability: a peripheral rim smaller than 4 mm, a tear longer than 10 mm, and homogenous aspect of meniscal tissue. In two rounds with an interval of at least 6 weeks, three orthopedic surgeons and three musculoskeletal radiologists studied the preoperative MRI scans of 63 patients with a longitudinal full-thickness medial or lateral meniscal tear. All patients had an arthroscopic meniscal repair. The blinded images were evaluated measuring the tear length and rim width and meniscal aspect was classified. Agreement was calculated using the linear-weighted kappa coefficient () and the intraclass correlation coefficient (ICC). Examiner agreement strength was defined according to the guidelines of Landis and Koch. Intraobserver agreement was poor to good (, 0.12-0.72) for the classification of the meniscal aspect and decreased in lateral meniscal tears. The interobserver agreement for meniscal aspect was mainly poor to fair (, 0.09-0.53). The intraobserver reliability for measurement of the length of the meniscal tear was moderate to excellent (ICC, 0.51-0.80) for all observers in both rounds and moderate to good (ICC, 0.59-0.73) for measurement of the peripheral rim width. The interobserver agreement on tear length and rim width was moderate in both rounds (ICC, 0.58 and 0.50 in round 1; 0.50 and 0.50 in round 2, respectively). Tear length and rim width are the only two measurements with moderate to good agreement. However, these measurements do not predict reparability of longitudinal meniscal tears on MRI images.
The rare case of a false aneurysm of the profunda femoris artery as an iatrogenic complication of dynamic hip screw (DHS) osteosynthesis is described. A review of the literature is given, with special reference to radiologic intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
