The impact of peripheral arterial disease: A proposal for a new classification.

Clasically, intermittent claudication, an intermediate stage in peripheral arterial disease, has been considered as a benign condition when considering only the muscular pain on walking. In this paper our aim is to attract attention about the effects linked to ischemic pain and the oxidative injury resulting from episodes of ischemia/reperfusion. Throughout this process alterations in calcium homeostasis as well as uncontrolled generation of reactive oxygen species, in association with the mitochondrial dysfunction and inflammatory phenomena, could lead to accelerate atherosclerosis, with an increased cardiovascular risk stated by means of a reduced ankle-brachial index.

Repair of bilateral true aneurysms of the dorsalis pedis artery.

Aneurysms of peripheral arteries are infrequent, with an incidence <1%. Dorsalis pedis artery (DPA) aneurysms are extremely rare, and most of them are pseudoaneurysms secondary to trauma or iatrogenic injuries. We report the first case of simultaneous (synchronous) bilateral DPA true aneurysms and how we repaired them.

[Cerebral hyperperfusion syndrome in carotid revascularisation surgery].

Introduction: Cerebral hyperperfusion syndrome (CHS) is a serious complication of carotid revascularisation surgery associated with both carotid endarterectomy and carotid stenting.

Aim: To review the literature published to date on CHS with the aim of updating the data available on its incidence, pathophysiology, clinical features, risk factors, diagnosis, management and treatment.

Development: Carotid revascularisation surgery entails a transient increase in cerebral blood flow, and if this increase is more than 100% of the pre-operative value, then hyperperfusion occurs.

[Laparoscopy-assisted aortobifemoral bypass through the transperitoneal retrorenal approach].

The aim of laparoscopic vascular surgery in the aortoiliac segment is to replicate the excellent outcomes of open aortic surgery while providing the advantages of minimally invasive surgery. We report the case of a 49-year old man with disabling hip claudication and rest pain in his left lower extremity. On examination the patient had reduced right femoral pulse and absent pulses in his left lower extremity.
