Low-molecular-weight heparin for prevention of venous thromboembolism after varicose vein surgery in moderate-risk patients: a randomized, controlled trial.

Background: Deep vein thrombosis (DVT) after varicose vein surgery (VVS) is not well recognized. Observational studies have yielded variable estimates of the risk, but evidence from randomized trials is lacking. Our aim was to compare the use of thromboprophylaxis with and without low-molecular-weight heparin (LMWH).

Shotgun wound and pellet embolism to the intracranial carotid artery.

Missile embolism into the cerebral circulation is a very unusual complication of shotgun wounds to the chest or neck. We report a case of an 11-year-old boy who sustained an air gunshot wound and pellet embolism to the intracranial carotid artery. The cerebral artery pellet embolus resulted in contralateral hemiplegia.

[The quality of information available on the internet about aortic aneurysm and its endovascular treatment].

Introduction And Objectives: To evaluate the readability, accessibility, usability, and reliability of information available on the Internet in the Spanish language about aortic aneurysm and its endovascular treatment, and to determine whether this information source provides comprehensible material that will enable patients to participate in decisions regarding their condition.

Methods: In November 2010, information from the Internet was compiled by entering the terms "aneurisma aorta" (aortic aneurysm) and "endoprótesis aorta" (aortic endoprosthesis) in the most widely used search engines: Google, Yahoo, and MSN/Bing. The first 30 pages provided by each search engine were analyzed.
