[Percutaneous balloon angioplasty for treatment of chronic thromboembolic pulmonary hypertension].

Chronic thromboembolic pulmonary hypertension is characterized by the presence of organized thrombotic material in the pulmonary arteries which causes elevation of the pulmonary vascular resistance, right heart failure, and death if not treated. Pulmonary thromboendarterectomy is the treatment of choice and can be curative when the obstruction is proximal. There are cases in which this therapy is not possible, and pulmonary angioplasty is a therapeutic alternative of growing interest.

Safety and feasibility of balloon-expandable stent implantation for the treatment of type I endoleaks following endovascular aortic abdominal aneurysm repair.

Aims: The occurrence of type I endoleaks represent an ominous sign after endovascular aneurysms repair (EVAR). We report our experience using balloon-expandable stents (BES) for the treatment of proximal Type I endoleaks at five high-volume hospitals in Argentina.

Methods And Results: Of 1,395 patients who underwent EVAR, we retrospectively collected data of 29 (2%) consecutive patients who underwent additional BES to repair proximal type I endoleaks.

Isolation of Chlamydophila pneumoniae from atheromas of the carotid artery and their antibiotics susceptibility profile.

Background: Atherosclerosis is pathogenically similar to a chronic inflammatory response. Peripheral arterial disease (PAD) is a common manifestation of atherosclerosis. Chlamydophila pneumoniae has been suggested to play a role in the origin of PAD.
