Background : The purpose of our study was to evaluate the influence of respiratory cycle on proximal renal artery (RA) motion in twenty consecutive patients with abdominal aneurysm and the potential impact on endograft deployment during endovascular aneurysm repair (EVAR). Methods : Prior to the device introduction, a preoperative angiography to define the location of the RAs was performed by a calibrated pigtail catheter. A measuring tape on the table served as the reference point for all measurements. Images of RA levels were acquired during expiration (E) and inspiration (I) cycles. In order to have homogenous comparative values for each patient during inhalation, the anaesthesiologist maintained a controlled inspiration with a uniform pressure of 30 cm of water. Motion of the RAs was defined as the changes in distance between E and I measures, adjusted to the calibrated pigtail. Results : The median right proximal RA motion was 3.0 mm (IQR 2.4 mm ; range : 0 to 5.6 mm). The median left proxi - mal RA motion was 3.1 mm (IQR 2.2 mm ; range : 0.54 to 5.6 mm). The current results demonstrate the proximal RAs motion during breath with a median magnitude of 3 mm, without significant differences between both RA (P = .83). Conclusion : Our data confirm the RAs motion during respiratory cycle. More than the predictive absolute value of the RA motion between inspiratory and expiratory phases, it is the motion itself which is important. This unrecognized condition, even if it interests only a minority of patients, could potentially have clinical disastrous consequences : Potential stenosis or covering of RAs.

Stroke is the third leading cause of death in the western world. Calcification noted on cone beam computerized tomography, frequently used to evaluate the maxillofacial structures for extent of tumor, trauma, and implant placement, may indicate atherosclerotic disease in the carotid artery. Internal carotid artery stenosis is a recognized risk factor for stroke; multiple, large randomized controlled trials have demonstrated a decreased risk of stroke after repair of the stenotic artery. Recognition of calcified carotid artery plaque, on cone beam computerized tomography during the course of surgical care may offer the opportunity for stroke risk reduction. © 2013 American Association of Oral and Maxillofacial Surgeons.

Background: Calf vein diameters during compression with two different stocking brands are assessed as well as quality of life. Patients and methods: 60 subjects (53 female) with painful legs were randomized to either wearing the Venotrain micro® (VM) or the Venotrain ulcertec® (VU) compression stocking for 2 weeks. All calf - veins were assessed in cross - sectional plane by Duplexsonography native and through the compression stockings. The diameters of 2 gastrocnemius muscle - veins (GV), the short saphenous vein (SSV) and the posterior tibial vein (PTV) were compared intra - individually, with and without compression. Results: Mean diameters (± SD) decreased significantly under compression (p < 0.0001) in the standing position: In the antero-posterior (ap) plane of the GV by 6.5 (± 16.6) % under VU and 8.2 (± 16.5) % under VM, in the SSV 9.7 (± 15.8) % under VU and 5.7 (± 19.2) % under VM. No significant change (p = 0.48) was seen in the PTV. In the prone position the relative ap - diameter changes in the medial GV were significantly smaller for the VM (37.5 ± 51.0 %) compared to the VU compression stocking (52.4 ± 51.8 %) (p = 0.016). The quality of life assessment scores improved significantly for the VU - and the VM - compression stocking. Venous diameters did not correlate with quality of life scores. Conclusions: Intra - individually tested the calf muscle vein diameters decrease under compression, more pronounced in the prone than in the standing position. In the ankle area the PTV does not decrease in standing subjects. Quality of life assessed increases for both compression stockings. © 2014 Hans Huber Publishers, Hogrefe AG, Bern.

A case of ergotism is presented to illustrate the role of duplex ultrasonography in the diagnosis and management of this nonatherosclerotic cause of peripheral arterial disease. Historical aspects of ergotism are discussed together with reference to the relative vulnerability of different segments of the arterial circulation. Our case emphasizes the potential for complete reversibility of the vascular changes if recognized early.

Compared to normal controls, platelets from myotonic dystrophy (MyD) patients, released significantly more -thromboglobulin (TG) and generated more thromboxane B(2) (TXB(2)) when platelet aggregation was induced by ADP (1.5 M) or epinephrine 1 M. TXB(2) generation in MyD platelets at 1 and 3 min was positively correlated (p < 0.05) to platelet aggregation (PA). This suggests that, 1 min after the addition of the PA inducers, the platelets of MyD patients are already at the second (irreversible) phase of PA. Together with our previous data, these results may indicate hyperactivity of platelets caused by a membrane abnormality in MyD.
