Background and purpose
Placement of flow-diverters across the ostia of major ICA branches carries a risk of arterial occlusion. We determined the rate of occlusion of the supraclinoid ICA branches and the related symptoms, following coverage with flow-diverters.Materials and methods
A systematic search was performed in PubMed, MEDLINE, and EMBASE. We selected studies reporting treatments with flow-diverters in which the device was placed across the ostium of the OphtA, PcomA, or AchorA. Random-effects meta-analysis was used to pool the following outcomes: rate of arterial occlusion, diminished flow, incidence of related symptoms, factors associated with arterial occlusion.Result
Twenty-one studies evaluating 1152 supraclinoid ICA branches were included in the meta-analysis. The incidence of OphtA occlusion and associated symptoms was 5.9% (95 CI%?=?3.1–8.6%) (incidence rate?=?6% per patient-year), and 0.8% (95% CI?=?0.1–1.4%) (incidence rate?=?0.8% per patient-year), respectively. Although asymptomatic in all cases, PcomA showed a higher occlusion rate (20.7%, 95% CI?=?8.9–32.4%) (incidence rate?=?19.5% per patient-year). AchorA was occluded in 1% (95% CI?=?0.3–2.4%) of cases, with approximately 1% (95% CI?=?0.4–2.3%) of transient neurological symptoms (incidence rate?=?0.96% per patient-year). There was a trend toward higher odds of arterial patency among arteries arising from the aneurysm (OR?=?2.94, P?=?0.06). Demographic factors and multiple stents were not associated with higher risk of arterial impairment. Adequate collateral circulation was reported in 94.5% of patients with arterial occlusion.Conclusions
During aneurysm treatment, the ostium of the supraclinoid ICA branches can be covered with flow-diverter devices with low rates of neurological symptoms related to arterial occlusion. 相似文献5.

Introduction
Shoulder arthroplasty is a common intervention and functional demands evolve with the improvement of outcomes. There is no consensus to answer demands of patients wishing to return to sport after total shoulder arthroplasty (TSA).Material and method
Retrospective study of 377 patients undergoing primary anatomical or reverse TSA between 2001 and 2016, of which 87 (99 prostheses) returned to sport and were reviewed with a minimum follow-up of two years. Depending on the type of sport, two categories were established: sports not involving the shoulder (group 1), sports involving the shoulder (group 2).Results
Among the patients, 29.5% of anatomic and 23.5% of reverse TSA returned to sport. There was no significant difference between the two types of prosthesis in terms of recovery rate (P = 0.56), sports category (P = 0.77), or delay (P = 0.49). In terms of category of sport, the group 1 was composed of 56 patients and the group 2 was composed of 43 patients. Group 1 had a significantly larger proportion of women (P = 0.001). The distribution between anatomic and reverse TSA was equivalent in both sport subclasses (P = 0.77). The delay of return to sport was significantly longer in group 2 (P = 0.009).Conclusion
The results of this study confirm our main hypothesis on the possibility of a return to sport activity after anatomic or reverse TSA including sports involving the shoulder such as tennis, hunting or sailing. 相似文献6.

Medial thalamic damage produces memory deficits in humans (e.g., Korsakoff’s syndrome) and experimental animals. Both the anterior thalamic nuclei (ATN) and rostral intralaminar plus adjacent lateral thalamic nuclei (ILN/LT) have been implicated. Based on the differences in their main connections with other neural structures, we tested the prediction that ATN lesions would selectively impair acquisition of spatial location discrimination, reflecting a hippocampal system deficit, whereas ILN/LT lesions would impair acquisition of visual pattern discrimination, reflecting a striatal system deficit. Half the rats were first trained in a spatial task in a water maze before switching to a visual task in the same maze, while the remainder were tested with the reverse order of tasks. Compared with sham-operated controls, (1) rats with ATN lesions showed impaired place learning, but normal visual discrimination learning, (2) rats with ILN/LT lesions showed no deficit on either task. Rats with ATN lesions were also hyperactive when their home cage was placed in a novel room and remained more active than ILN/LT or SHAM rats for the subsequent 21 h, especially during the nocturnal phase. These findings confirmed the influence of ATN lesions on spatial learning, but failed to support the view that ILN/LT lesions disrupt striatal-dependent memory. 相似文献

Objective
To validate the Heidenreich criteria for patient selection for unilateral retroperitoneal lymph node dissection (RPLND) for residual masses after chemotherapy for nonseminomatous germ cell tumor (NSGCT).Subjects/patients and methods
For validation, the data of 59 patients who underwent RPLND for residual masses of NSGCT were used. Of these patients, 23 (39 %) qualified for a modified RPLND, the others had an indication for a bilateral dissection. Results from histopathology after RPLND and follow-up data for relapse inside or outside the zone of the resection template were considered for validation.Results
In the study cohort, median age at time of RPLND was 31 years. The 2-year disease-free survival was 90 and 96 % for the bilateral and the unilateral RPLND patients, respectively. Overall, 8 (14 %) relapses were observed after a median follow-up of 54 month. Of these, 6 were outside of the resection field and 2 were in-field. Of the 23 patients with indication for a modified RPLND, 1 patient relapsed in the contralateral testis and 1 inside the modified RPLND template. No relapse was observed outside the modified RPLND field and inside the untouched contralateral RPLND field. The Heidenreich criteria did therefore not misclassify a single patient.Conclusion
The Heidenreich criteria for the selection of candidates for unilateral RPLND for residual masses after chemotherapy allow a highly reliable selection of patients. The application of the Heidenreich criteria can help to reduce comorbidity and invasiveness of RPLND. 相似文献10.

This study analyzes the muscle moment arms of three different reverse shoulder design philosophies using a previously published method. Digital bone models of the shoulder were imported into a 3D modeling software and markers placed for the origin and insertion of relevant muscles. The anatomic model was used as a baseline for moment arm calculations. Subsequently, three different reverse shoulder designs were virtually implanted and moment arms were analyzed in abduction and external rotation. The results indicate that the lateral offset between the joint center and the axis of the humerus specific to one reverse shoulder design increased the external rotation moment arms of the posterior deltoid relative to the other reverse shoulder designs. The other muscles analyzed demonstrated differences in the moment arms, but none of the differences reached statistical significance. This study demonstrated how the combination of variables making up different reverse shoulder designs can affect the moment arms of the muscles in different and statistically significant ways. The role of humeral offset in reverse shoulder design has not been previously reported and could have an impact on external rotation and stability achieved post‐operatively. © 2015 Orthopaedic Research Society.
