Sex Differences In Collateral Remodeling Following Hindlimb Arterial Occlusion, Laura Burckhardt
Sex Differences In Collateral Remodeling Following Hindlimb Arterial Occlusion, Laura Burckhardt
Master's Theses
Clinical evidence indicates a higher incidence of peripheral arterial occlusive disease and associated likelihood of critical limb ischemia in women, as well as worse prognosis and decreased survival post myocardial infarction. Therefore, understanding the possible differences in underlying vascular compensation mechanisms is crucial. With arterial occlusions, necrosis and tissue injury can be naturally mitigated by the collateral circulation, improving patient prognosis. Previous sex-comparison studies describing differences in vascular remodeling are inconsistent. Therefore, the aim of this study was to describe the effect of arterial occlusion on collateral remodeling in healthy male and healthy reproductive-stage female mice. At 7 days following …
Sex Differences And The Effects Of Exercise Training On Functional Vasodilation Following Arterial Occlusion In The Balb/C Mouse Spinotrapezius, Britta Nelson
Master's Theses
Peripheral arterial occlusive disease (PAOD) often presents as intermittent claudication, which may be caused by impaired vasodilation. Impairment of resistance vessels may contribute to the pathogenesis of PAOD, and explain the poor correlation between resting blood flow and limb function. Collateral function following arterial occlusion is not well defined, however collaterals and arterialized collateral capillaries (ACCs) in male and female animal models exhibit impaired vasodilation following arterial occlusion, which can potentially be improved with exercise training. Furthermore, resistance vessels in the ischemic tree and stem are likely involved in the pathogenesis of PAOD, however the relative importance of each is …

The Impacts Of Arterial Occlusion, Sex, And Exercise On Arteriogenesis And Functional Vasodilation, Megan Tze-Mei Chu
Master's Theses
The most frequent clinical presentation of peripheral arterial occlusive disease (PAOD) is intermittent claudication, which may be caused by impaired vasodilation. Patients demonstrate both local and systemic impairments in vasodilation, but as the collateral circulation is the primary site of resistance to the ischemic zone, impaired collateral vasodilation would have the greatest potential to induce claudication. Collateral function following arterial occlusion is not well defined, but immature collaterals may demonstrate impaired vasodilation in animal models, although this is potentially improved with exercise training. Furthermore, as females exhibit poorer physical function with ischemia and less improvement with therapeutic exercise, there appears …
