There were 140 patients operated for the celiac trunk (CT) and renal arteries extravascular compression (FC) in diaphragmatic aorta segment. The clinical syndromes of chronic abdominal ischemia and vasorenal hypertension were depicted. The predisposing factors of CT EC is the patients' dolichomorphic constitution with epigastric angle of < or = 70 degrees. The effectiveness of differentiated tactic choice of operative intervention magnitude according to the disease stage was shown. The late follow-up results witnesses the necessity of timely and adequate treatment.

Objective: The employment of the no-touch technique in harvesting the great saphenous vein (GSV) for coronary artery bypass grafting has been associated with a significant improvement in clinical patency rates. Despite these advantages, such grafts may predispose patients to complications in the lower limbs. This study endeavors to evaluate the incidence of complications in the lower extremities by deploying an enhanced protocol for the no-touch harvesting technique.

Coronary circulation plays an essential role in delivering oxygen and metabolic substrates to satisfy the considerable energy demand of the heart. This article reviews the history that led to the current understanding of coronary physiology, beginning with William Harvey's revolutionary discovery of systemic blood circulation in the 17th century, and extending through the 20th century when the major mechanisms regulating coronary blood flow (CBF) were elucidated: extravascular compressive forces, metabolic control, pressure-flow autoregulation, and neural pathways. Pivotal research studies providing evidence for each of these mechanisms are described, along with their clinical correlates.

Blood platelets are produced by megakaryocytes (MKs), their parent cells, which are in the bone marrow. Once mature, MK pierces through the sinusoid vessel, and the initial protrusion further elongates as proplatelet or buds to release platelets. The mechanisms controlling the decision to initiate proplatelet and platelet formation are unknown.

We aimed to evaluate the prognostic implications of resistive reserve ratio (RRR), a composite measure of flow and pressure parameters that represents the vasodilatory capacity of the coronary arteries, in patients with angina with nonobstructive coronary artery disease (ANOCA) and MB, in comparison with coronary flow reserve (CFR).
Methods And Results: In this retrospective cohort study, we included patients with ANOCA who underwent coronary reactivity testing, where MB was identified by transient constriction in coronary artery segments between systole and diastole.
