Blood clot issues put futures of star athletes Stamkos, Bosh in doubt

CBC Sports  


"Generally it can be anywhere from one to three months but it's a fine line. You have to balance the risk of bleeding versus clotting," says Dr. Thomas Forbes, a vascular surgeon at the Peter Munk Cardiac Centre in Toronto. In other words, a player like Stamkos has to know that if he is cut, his blood will be able to clot...

Experts: Steven Stamkos has a long way to go in recovery



Dr. Thomas Forbes, a vascular surgeon at Toronto's Peter Munk Cardiac Centre, believes that Stamkos likely developed the blood clot in his right shoulder from repeated trauma to the vein. The affected blood vessel rests between the collar bone and the top rib and would be pinched, even scarred, when Stamkos raises his right arm above his shoulder. It's an action the four-time all-star and two time Rocket Richard Trophy winner has performed countless times by winding up for a slapshot...

Steven Stamkos has rib removed in blood clot surgery

Sports Illustrated  


“Normal recovery for range of motion and exercise would be about one month from just the surgery alone,” Dr. Thomas Forbes, a vascular surgeon at Toronto’s Peter Munk Cardiac Centre, told TSN. “Doctors would then recommend some period of time on blood thinners, perhaps one month, which also complicates the timeline.”...

Canadian Cardiovascular Society/Canadian Society of Cardiac Surgeons/Canadian Society for Vascular Surgery joint position statement on open and endovascular surgery for thoracic aortic disease Canadian Journal of Cardiology


In 2014, the Canadian Cardiovascular Society (CCS) published a position statement on the management of thoracic aortic disease addressing size thresholds for surgery, imaging modalities, medical therapy, and genetics. It did not address issues related to surgical intervention. This joint Position Statement on behalf of the CCS, Canadian Society of Cardiac Surgeons, and the Canadian Society for Vascular Surgery provides recommendations about thoracic aortic disease interventions, including: aortic valve ...

PC172. The Spectrum and Management of Noniatrogenic Vascular Trauma in Children Journal of Vascular Surgery


This study identified the spectrum of noniatrogenic pediatric vascular injuries and their associated outcomes at a large tertiary pediatric hospital. Methods This was a retrospective review of a prospectively maintained trauma database identifying children with noniatrogenic vascular injuries managed between 1994 and 2014. Results A total of 198 patients were identified. Those with a digital or intracerebral vascular injury (92 of 198) were excluded from analysis. The remaining 106 patients represented 1.2% of all traumas ...

IP143. Learning Curves in Vascular Surgery: A Systematic Review of Current Practice Journal of Vascular Surgery


Defining learning curves in vascular surgery assists in adopting new techniques and educating new vascular trainees. Cumulative sum (CUSUM) analysis is often used for these learning curves and has been readily adopted in both cardiac and general surgery for quality monitoring and medical education research. This technique graphs sequential procedures and can detect deviations in performance for the better or worse. A number of comparatively new CUSUM methods, including risk-adjusted (RA-CUSUM) analysis and ...

Clinical outcomes and material properties of in situ fenestration of endovascular stent grafts Journal of Vascular Surgery


In situ fenestration of endovascular stent grafts has been used as a method for branch vessel revascularization in urgent and emergent settings. The objective of this manuscript was to review the clinical and experimental evidence related to this technique. Methods PubMed, MEDLINE, and Embase databases were searched for papers published until December 2015 describing in situ fenestration of aortic stent grafts. Benchtop, animal, and human studies were included. Results The literature review identified 118 articles, of ...

Genetic Deletion of Galectin-3 Does Not Impair Full-Thickness Excisional Skin Healing The Journal of Investigative Dermatology


Impaired skin healing represents a clinically significant problem associated with vascular insufficiency, diabetes, and increasing age (Nelson and Bradley, 2007; Sen et al., 2009). Although the underlying etiology of nonhealing skin wounds is complex, it is established that the tissue remains in a proinflammatory state (Schultz and Wysocki, 2009; Widgerow, 2011). Gaining an understanding of the molecular mechanisms involved in the persistence of the inflammatory state and of the associated paracrine effects of prolonged inflammation on ...
