Impaction allografting is the only technique, to date, that has been shown to reverse the loss of bone stock encountered during revision hip arthroplasty. However, early stem subsidence, dislocations and a high occurrence of periprosthetic fractures are well documented with this method. This article reviews the biomechanical and biological characteristics of compacted morsellised graft, on the ...

Background: Peripheral arterial disease is a source of morbidity and mortality. Surgical vascular reconstruction is a treatment option but probability of failure and complications are important concerns. In this study, we evaluated outcome of surgical infrainguinal reconstruction and factors affecting graft patency for a period of one year. Methods: In this cohort study, 85 consecutive patie...

In recent times, practice in cardiac surgery has shifted towards using endoscopic techniques to harvest the saphenous vein from the leg for use as a bypass graft. A paper published in the New England Journal of Medicine (NEJM) in 2009 raised concerns over increased graft occlusion rates in veins harvested endoscopically. This NEJM paper has been criticized, but has nonetheless been influential ...

In most studies, aspirin has been shown to be effective for a period of 1 year in reducing the frequency of saphenous vein bypass graft occlusion when begun 1 day before surgery, on the day of surgery, or the day after surgery. Effective doses of aspirin range from 100 to 975 mg/d. Aspirin in combination with dipyridamole is effective in the prevention of saphenous vein bypass graft occlusion i...

Acute thrombotic occlusion of an aortocoronary bypass graft to the left anterior descending coronary artery (LAD) was successfully dissolved by selective infusion of streptokinase into the graft at 2000 U/min for 1 hour via catheter. There was partial recanalization of the graft and complete filling of the LAD within 15 minutes. After 1 hour of lysis, the graft was completely patent, although h...

To determine whether antiplatelet therapies improve saphenous vein graft patency after coronary artery bypass grafting, we compared 1) aspirin (325 mg once daily), 2) aspirin (325 mg three times daily), 3) aspirin and dipyridamole (325 mg and 75 mg, respectively, three times daily), 4) sulfinpyrazone (267 mg three times daily), and 5) placebo (three times daily). Therapy with dipyridamole and s...

La patología vascular oclusiva es causante de diversas y variadas manifestaciones clínicas, algunas ellas con catastróficas consecuencias para el paciente. Dado que las causas tal oclusión son muy variadas, hemos abordado en un artículo previo reciente esta misma revista trombóticas. En presente recopilamos adicionales intravascular. Vascular occlusion has multiple, diverse clinical manifestati...

PURPOSE To evaluate the acute and midterm effectiveness of a novel vascular occlusion device for embolization of the internal iliac artery (IIA) before endovascular repair of aortoiliac aneurysms. MATERIALS AND METHODS Between March 2005 and April 2006, nine men (mean age, 75 years +/- 5; range, 66-83 y) with aortoiliac aneurysms underwent bifurcated endovascular stent-graft procedures. All t...

OBJECTIVES To analyze the histological changes observed in venous grafts subjected to arterial blood flow as a function of the duration of the postoperative period to optimize their use in free flap reconstructions. METHOD Twenty-five rats (7 females and 18 males) underwent surgery. Surgeries were performed on one animal per week. Five weeks after the first surgery, the same five animals were...
