Five patients (9%) required reoperation, in one patient each for postoperative bleeding,
acute cholecystitis, homograft occlusion, homograft-duodenum fistula, and aneurysmal degeneration. No recurrence of infection was reported.
Conclusion: These results demonstrate an encouraging outcome after cryopreserved allograft implantation for the treatment of vascular infections in the abdominal aorta. The data represent a basis for future comparisons with other treatment modalities for vascular infections, including silver-coated prostheses and autogenous femoral veins.(J Vasc Surg 2010;52:323-30.)”
“For a flickering light with two or more frequency components, the temporal envelope of the flickering light is perceived, although there is no frequency component at the frequency of the envelope. To address the processing of
the temporal envelope, we compared LCL161 order cortical responses to the envelope of amplitude-modulated (AM) flickering lights with responses to sinusoidal flickering lights. We measured magnetoencephalographic (MEG) responses to AM and sinusoidal flickering lights while changing the frequency of the temporal envelope of AM flickering light and the stimulus frequency of sinusoidal flickering light. The result showed that the strength of the MEG response to sinusoidal flickering light increased with stimulus frequency in the low frequency range. This probably resulted from the band-pass filtering in the visual system. However, such an increase in the low frequency range was not observed for the envelope of AM flickering light. The PF299804 supplier selleck absence of the increase in MEG responses suggests that the envelope of AM flickering light is not subject to band-pass filtering in the visual system. It is therefore possible that the envelope is represented after the band-pass filtering stage. (C) 2010 Elsevier Ireland Ltd. All rights reserved.”
“Background: Aggressive endoluminal therapy for
superficial femoral artery (SFA) occlusive disease is commonplace, but the outcomes of current management of recurrent disease have not been well defined. This study examined the outcomes of endoluminal and open interventions for recurrent SFA disease.
Methods: A database of patients undergoing endovascular treatment of the SEA between 1986 and 2008 was retrospectively queried, and those with recurrent disease were selected. Outcomes were determined by Kaplan-Meier survival analyses, and the Cox proportional hazard model was used for time-dependent variables.
Results: Symptomatic SFA disease resulted in endovascular treatment in 735 limbs in 631 patients (64% male; average age, 67 years). The restenosis rate was 16% +/- 3% at 5 years. Restenosis developed in 222 patients, of whom 58 remained asymptomatic and 164 underwent repeat intervention comprising percutaneous transluminal angioplasty (PTA) in 59% and bypass in 41%.
