      Endovenous ablation is contraindicated or relatively unsuitable when venous anatomy precludes catheter-based treatment, specifically: aneurysmal dilation of the GSV close to the saphenofemoral junction, subcutaneous location of truncal veins above the saphenous fascia and close to the skin, and significant tortuosity of the GSV or SSV. [1] In these scenarios, high ligation and stripping is recommended as the preferred alternative (grade 1 strong recommendation

      Thrombotic Risk Stratification Both surgical and endovenous approaches carry VTE risk, but surgery has substantially higher rates. Thrombotic complications after isolated endovenous ablation are uncommon (<1% for DVT and PE), whereas patients undergoing open procedures such as high ligation and stripping with phlebectomy may experience VTE rates as high as 6.25%. [2] Concomitant phlebectomy of tributaries has been identified as an independent risk factor for VTE development. [2] For high-risk patients undergoing endovenous ablation, pharmacological thromboprophylaxis is suggested (grade 2 weak recommendation). [2] Risk stratification using tools like the Caprini score may identify patients at elevated risk, with those scoring ≥7 potentially benefiting from chemoprophylaxis.

      The conservative influence of property does not, however, depend on primogeniture or even inheritance -- features that gave property a valuable role in Burke's political system as well as in the political theories advanced by Hegel and Plato. n11 Within a single lifetime, property tends to make the property owner more risk-averse. This aversion applies both to public decisions [*291] affecting property, such as taxes, and to personal decisions that might diminish one's property, such as investment strategies and career choices. Inheritance and capital appreciation are only additional characteristics of traditional notions of property that tend to stabilize social stratification.
