Prospective randomized 1-year follow-up comparison of bilateral subthalamotomy versus bilateral subthalamic stimulation and the combination of both in Parkinson’s disease patients: It has been suggested that potential risk of hemiballismus after subthalamotomy makes DBS preferable to ablation for IPD treatment; however, cost and the need for regular electrode control have also been observed as disadvantages to It has been suggested that potential risk of hemiballismus after subthalamotomy makes DBS preferable to ablation for IPD treatment; however, cost and the need for regular electrode control have also been observed as disadvantages to stimulation.
The objective was to compare efficacy and safety of different surgical approaches to STN, in a prospective randomized pilot study. Sixteen consecutive IPD patients randomized to receive either: One patient died and was excluded from the analysis.
Total and motor UPDRS scores, as well as drug-induced dyskinesias improved significantly at 1 year follow-up, regardless of the procedure administered and without statistically significant differences between treatment modalities.
Psychiatric retrofariingeos of patients subjected to bilateral stimulation and lesion, revealed slight increment in apathy and irritability scores, coinciding with significant deterioration of mentation, behaviour and mood as measured using the UPDRS.
One patient presented persistent hemiballismus and required ulterior posteroventral pallidotomy. In this small group of patients, overall motor performance significantly improved after all three procedures, without major differences in outcome.
Adverse events were, nevertheless, observed after both ablation and stimulation. The role of bilateral subthalamotomy in patients unable to receive a DBS electrode-implant merits further exploration in a larger series of patients with longer follow-up.
Inhomogeneous two-dimensional photonic media: In this paper, we have performed a statistical study retrrofaringeos the average light transmission, over the range of wavelengths — nm, In this paper, we have performed a statistical study of the retrofarinfeos light transmission, over the range of wavelengths — nm, for two-dimensional photonic structures with different homogeneity quantified by the Shannon index. The photonic structure is a square lattice of circular pillars and the homogeneity rretrofaringeos varied by clustering pillars in the crystal unit cells.
We have calculated absfesos light retgofaringeos for 50 different crystal realizations permutating cluster position in the crystal for each Shannon index value. We have observed a linear trend of the average transmission as a function of the crystal homogeneity. Furthermore, we have found a linear dependence of the average light transmission on the mean distance between pillars in the photonic structures. Gamma knife radiosurgery in cerebral arteriovenous malformations.
The role of atrial vessels in aortic root and mitral valve operations. Ovine femoral artery bypass grafting using saphenous vein: Here, we report a surgical model in sheep intended to study IH development in SVGs, which can also be used for the evaluation of potential alternative treatments.
Post-implant, mid-term, and pretermination angiograms were quantified, and harvested SVGs were evaluated using quantitative histomorphometry. We describe a peripheral arterial surgical technique that models the progression of SVG pathology. Angiographic analysis showed a progressive dilation of SVGs leading to worsening diametrical matching to the target artery and reduced blood flow; and histomorphometry data showed an increase in IH over time.
Bilateral SVGs implanted onto retrofadingeos femoral arteries of sheep produced, controlled and consistent angiographic and histomorphometric results for which direct correlations could be made.

However, several proposals have never been demonstrated. In this paper, we describe 2 vascular conduits that have never In this paper, we describe 2 vascular conduits that have never reteofaringeos been objectively shown to supply the conduction system. Twenty human hearts from subjects aged between 15 and 65 years–with and without coronary disease–were dissected after anterograde and retrograde injection with latex butaclor E by means of a technique developed by the authors.
These findings may be of major significance both in clinical cardiology and in cardiovascular surgery. The first septal artery supplies the atrioventricular node.

Anatomical reasons for the discrepancies in atrioventricular block after inferior myocardial infarction with and without right ventricular involvement. The incidence of arrhythmias after acute myocardial infarction of the inferior wall varies with the affected segment and increases when there is right ventricular involvement.
This paper provides a clear review of the blood supply to absxesos This paper provides a clear review of the blood supply to the conduction system and gives an anatomic explanation of that supply. We dissected 20 human hearts after anterograde and retrograde injection of latex.

In rftrofaringeos heart, we dissected the conduction system and its blood supply. Retrograde perfusion enabled proper injection of the atrial vessels that originate at the beginning of the coronary trunks. We describe the 4 main arteries that supply blood to the conduction system. The classic concept included the atrioventricular node artery and the 1st septal artery. The incidence of arrhythmias after acute myocardial infarction of the inferior wall is greater when the occlusion of the coronary trunk is at or near the origin.
Coronary Anatomy for Surgeons. Vascular Injuries of the Upper Extremities. Upper extremity injuries are increasingly common among peripheral vascular injuries, as a result of penetrating trauma Figure Blunt trauma may also result in significant vascular injury primarily due to associated injuries such as Blunt trauma may also result in significant vascular injury primarily due to associated injuries such as fractures and dislocations.
Injuries to the brachial artery are most commonly reported. Ads help cover our server costs. Remember me on this computer. Enter the email address you signed up with and we’ll email you a reset link. Click here to sign up. Help Center Find new research papers in:
