Comparative StudyEndovascular treatment of penetrating thoracic outlet arterial injuries.
to establish the feasibility of stent-graft treatment of penetrating thoracic outlet arterial injuries. ⋯ endovascular treatment shows promise as a treatment modality for thoracic outlet arterial injuries. Long-term follow-up is required for comparison to the results of standard surgical repair.

Effect of intermittent pneumatic foot compression on popliteal artery haemodynamics.
the aim was to investigate the effect of intermittent pneumatic foot compression (IPC(foot)) on popliteal artery haemodynamics in normal individuals and in patients with intermittent claudication due to peripheral vascular disease (PVD) (Fontaine stage II). ⋯ current CFDI technology enables a reproducible estimation of popliteal artery flow velocities. IPC(foot)can significantly augment arterial calf inflow on an acute basis both in normals and claudicants. The increase of EDV and decrease of PI indicate that attenuation of peripheral resistance to flow is the main mechanism underlying the popliteal artery vFl enhancement on application of IPC(foot). Prospective trials on the long-term effect of IPC(foot)in the management of patients with PVD are indicated from the results of this study.

The use of preoperative transcranial Doppler variables to predict which patients do not need a shunt during carotid endarterectomy.
to analyse whether preoperative transcranial Doppler (TCD) variables can predict intraoperative shunt requirement. ⋯ preoperative TCD can be used to identify patients who do not require a shunt during carotid endarterectomy.

Comparative StudyEnhancing venous outflow in the lower limb with intermittent pneumatic compression. A comparative haemodynamic analysis on the effect of foot vs. calf vs. foot and calf compression.
intermittent pneumatic compression (IPC), an established method of deep-vein thrombosis prophylaxis, is also an effective means of leg inflow enhancement, improving the walking capacity and ankle pressure of claudicants, long-term. This study, using duplex ultrasonography, compares the haemodynamic effect of IPC of the (a) foot (at 120 mmHg [IPC(foot/120 mmHg)], and 180 mmHg [IPC(foot/180 mmHg)]), (b) calf (IPC(calf), 120 mmHg) and (c) both simultaneously (IPC(foot+calf), 120 mmHg), on the venous outflow of 20 legs of normals and 25 legs of claudicants. ⋯ all IPC modes proved effective, IPC(foot+calf)generating the highest venous outflow enhancement. Higher venous volumes expelled with IPC(foot+calf)explain its reported superiority on leg inflow over the other modes. Increase of applied pressure from 120 to 180 mmHg with IPC(foot)offered only a small outflow improvement. Venous haemodynamics at rest and with IPC in claudicants do not differ significantly from those in healthy subjects.

Comparative StudyA prolonged spinal cord ischaemia model in pigs. Passive shunting offers stable central haemodynamics during aortic occlusion.
to evaluate the effect of a modified aortic shunt on central haemodynamic variables during experimental thoracic aortic occlusion in a prolonged spinal cord ischaemia model. ⋯ the present experimental spinal cord ischaemia model, using double aortic cross-clamping with shunt, offers improved central haemodynamics. This enables the study of prolonged selective spinal cord ischaemia without interaction from vasoactive drugs or systemic reperfusion.
