Introduction: Peripheral arterial disease (PAD) is a common vascular condition that affects both quality of life and life expectancy with an increased risk of cardiovascular events.
Sources Of Data: A literature search was carried out of Pub-Med, MEDLINE, the Cochrane Library and Google Scholar from the establishment of these databases up to February 2012. The search was performed by using the keywords 'peripheral arterial disease' and one of the following words: 'management', 'investigations', 'risk factors', 'epidemiology', 'revascularization', 'cryoplasty', 'atherectomy' and 'gene therapy'. Studies were limited to those published in English language.
Areas Of Agreement: Aggressive risk factors modification is needed to reduce cardiovascular-related mortality in PAD patients.
Areas Of Controversy: Choice of endovascular or surgical intervention remains controversial in an ever-evolving field.
Growing Points: There is a rapid expansion of endovascular technologies aiming to improve the effectiveness of this modality.
Areas Timely For Developing Research: The advances in the fields of gene therapy and therapeutic angiogenesis mean these are potential future treatments. Tissue engineering is a developing area and aims to produce grafts with similar patency and infection profiles to those of autologous material. Further elucidation of the pathophysiology of atherosclerosis is required to provide new targets for pharmacotherapy.

Rotational flap versus long plantar flap for transmetatarsal amputation closure following revascularization.

Hospital Universitário Professor Edgard Santos, Federal University of Bahia, Salvador, Bahia, Brazil.
Objective: The integrity of the plantar flap is important for transmetatarsal amputation (TMA) classic closure. However, in ischemic wounds, the plantar flap can be compromised, making the TMA coverage difficult. The aim of this study was to compare the outcomes of rotational vs long plantar flaps for transmetatarsal amputation closure in patients with dysvascular partial foot amputations.

Background: Pulmonary arterial hypertension (PAH) is a deadly disease without effective non-invasive diagnostic and prognostic testing. It remains unclear whether vasodilators reverse inflammatory activation, a part of PAH pathogenesis. Single-cell profiling of inflammatory cells in blood could clarify these PAH mechanisms.

Objectives: The aim of this study was to investigate the expression characteristics and interrelationships of FNDC5 and pyroptosis-associated molecules in peripheral blood mononuclear cells of patients with coronary heart disease (CHD).
Methods: Patients were divided into stable angina (SA), unstable angina (UA), and acute myocardial infarction (AMI) groups based on different clinical symptoms. According to the Gensini score, they were then divided into mild, moderate, and severe lesion groups.

Arterial cannulation, commonly performed in the radial artery, is a widely used method for continuous blood pressure monitoring. Occasionally, the axillary artery is used as an alternate site of cannulation. However, complications like occlusion can lead to adverse events and severe outcomes.

Restenosis remains a long-standing limitation to effectively maintain functional blood flow after percutaneous transluminal angioplasty (PTA). While the use of drug-coated balloons (DCBs) containing antiproliferative drugs has improved patient outcomes, limited tissue transfer and poor therapeutic targeting capabilities contribute to off-target cytotoxicity, precluding adequate endothelial repair. In this work, a DCB system was designed and tested to achieve defined arterial delivery of an antirestenosis therapeutic candidate, cadherin-2 (N-cadherin) mimetic peptides (NCad), shown to selectively inhibit smooth muscle cell migration and limit intimal thickening in early animal PTA models.
