Lesion Localization and Limb Outcomes in Elderly Patients with and Without Type 2 Diabetes Mellitus Who Undergo Atherectomy-Assisted Endovascular Revascularization due to Symptomatic Peripheral Artery Disease.

Type 2 diabetes mellitus (T2DM) represents a major risk factor for peripheral artery disease (PAD). We aimed to evaluate the impact of T2DM on lesion localization and complexity, clinical presentation by Rutherford categories, and limb outcomes in elderly patients with symptomatic PAD undergoing endovascular revascularization. Five hundred consecutive patients with symptomatic infra-inguinal PAD who underwent rotational atherectomy-assisted endovascular revascularization were included.

Retrospective Case Control Matched Comparison of the Antegrade Versus Retrograde Strategy After Antegrade Recanalisation Failure in Complex de novo Femoropopliteal Occlusive Lesions.

Objective: To investigate dissection severity, need for bailout stenting and limb outcomes in patients undergoing antegrade vs. retrograde revascularisation.

Methods: Consecutive patients who underwent either antegrade or retrograde revascularisation after failed antegrade recanalisation of long femoropopliteal chronic total occlusion (CTO) due to symptomatic peripheral artery disease between January 2017 and June 2022 were studied.

Gastrobronchial fistula after toothbrush ingestion.

Gastrobronchial fistulous communications are uncommon complications of disease processes with only 36 previously reported cases. Described as complication of a number of conditions, such as previous gastroesophageal surgery, subphrenic abscess, and gastric ulcers (Jha P, Deiraniya A, Keeling-Robert C, et al. Gastrobronchial fistula--a recent series.

Coronary vasodilator effects of endogenous cannabinoids in vasopressin-preconstricted unpaced rat isolated hearts.

The mechanisms by which cannabinoids alter coronary vascular tone and cardiac performance are controversial. We investigated the effects of various cannabinoids in spontaneously beating Langendorff-perfused rat hearts. Bolus injections of anandamide (0.

CB(1) cannabinoid receptor antagonism promotes remodeling and cannabinoid treatment prevents endothelial dysfunction and hypotension in rats with myocardial infarction.

1. To study the long-term effects of altered cannabinoid receptor activity on myocardial and vascular function, Wistar rats were treated with the selective CB(1) antagonist AM-251 (0.5 mg kg(-1) d(-1)), the potent synthetic cannabinoid HU-210 (50 micro g kg(-1) d(-1)) or vehicle for 12 weeks after coronary artery ligation or sham operation.

The quest for a vascular endothelial cannabinoid receptor.

This review examines pharmacological and biochemical evidence that suggests the existence of an as yet undefined endothelial receptor that mediates endocannabinoid-induced vasodilation. The signaling mechanisms triggered through this receptor and its potential physiological role are also discussed. Since vasodilation is often associated with hypotension, mechanisms involved in the hypotensive actions of cannabinoids, including the endocannabinoids anandamide and 2-arachidonoylglycerol, are also briefly reviewed.
