The Year Book of Vascular Surgery brings you abstracts of the articles that reported the year’s breakthrough developments in vascular surgery, carefully selected from more than 500 journals worldwide. Expert commentaries evaluate the clinical importance of each article and discuss its application to your practice.
- Proper Supervised exercise programme increases maximum distance in 94% of patients (124-241m); and is associated with significant increase in myosin heavy chain I Protein expression compared to placebo. Bristol, UK. This adaptation failed in angio patients only (immediately after angio). >> could this be the explanation of the failure of iliac revascularization in the CLEVER trial to show a difference in walking distance?
- LSV valves (the last distal two) have specific distance and orientation that possibly creates a helical flow at the junction level. >> it is possible that in the future we will target the treatment towards those valves only. Univ of Hawaii.
- Dietary nitrate supplest in mice model improves revascularisation molecular and cellular activities in muscles compared to placebo. >> is their a real role for nutrition supplement for IC patients? (Germany – Circulation 2012)
- Carotid endarterectomy on asymptomatic patients with limited life expectancy are expected to perform poorly compared to normal life expectancy; therefore is probably better to avoid. The follow up used the American College of Surgeons database., reporting >12000 cases of asymptomatic, with >2500 of them had limited life expectancy. (NH. USA – Stroke 2012)
VENOUS DISEASES
- Is graduated compression bandaging (i.e. higher pressures at ankle and lower as bandage descends) BETTER than normal bandaging (or called negative bandaging (with higher pressure on calf) in improving venous pump? the answer is NO. the dynamics does NOT support the graduated compression in here: In 20 patients, all affected by greater saphenous vein (GSV) incompetence and candidates for surgery, NGCBs with median pressures higher at the calf (62 mmHg) than at the distal leg (50 mmHg) achieved a significantly higher increase of ejection fraction (median + 157%) compared with GCB, (+115%) with a distal pressure of 54 mmHg and a calf pressure of 28 mmHg (P < 0.001). (Austria. EJVES 2012)
- High heels in women – reduces muscle pump function (reduced ejection fraction and increased residual volume fraction). This was measured using plythesmography. (Brazil – J Vas Surg 2012)
