Arterial switch is a relatively novel surgical approach aimed at augmentation of blood flow at the account of less important arterial branches. The method consists in suturing vessels of different diameter end to end and end to side. Arterial switch is used for perfusion of donor organs, kidney in particular. The authors suggested a variant of arterial switch--intrapericardial subclavian to pulmonary arterial anastomosis--in the presence of stenosis of right ventricular outflow tract in tetralogy of Fallot. This anastomosis has several advantages over classical methods of surgical correction of Fallot's tetralogy. Coronary artery bypass surgery using mammary artery grafts is based on arterial switch principle and represents the most effective technique of treatment of coronary artery stenoses. Multiple experimental and clinical methods of arterial switch having been proposed and investigated by the authors since 1955 have found wide application in reconstructive surgery.

During the trunk to tail transition the mammalian embryo builds the outlets for the intestinal and urogenital tracts, lays down the primordia for the hindlimb and external genitalia, and switches from the epiblast/primitive streak (PS) to the tail bud as the driver of axial extension. Genetic and molecular data indicate that Tgfbr1 is a key regulator of the trunk to tail transition. Tgfbr1 has been shown to control the switch of the neuromesodermal competent cells from the epiblast to the chordoneural hinge to generate the tail bud.

The glycocalyx is an essential structural and functional component of endothelial cells. Extensive hemodynamic changes cause endothelial glycocalyx disruption and vascular dysfunction, leading to multiple arterial and venous disorders. Chronic venous disease (CVD) is a common disorder of the lower extremities with major health and socio-economic implications, but complex pathophysiology.

Objective: The aim of this study was to assess the short- and long-term outcomes of patients who underwent the arterial switch operation (ASO) at Siriraj Hospital in Thailand, and to identify postoperative complications and factors that significantly affect patient survival.
Materials And Methods: We retrospectively studied all patients with dextro-transposition of the great arteries and anatomic variants who underwent the ASO from January 1995 to December 2020. Twenty-year overall survival and 15-year freedom from reoperation/reintervention were estimated using the Kaplan-Meier method.
"May-Thurner syndrome as an underlying cause of unilateral left-sided deep vein thrombosis in a young healthy female: A case report".
Radiol Case Rep

Department of Radiology, Rafidia Surgical Hospital, Nablus, Palestine.
May-Thurner syndrome (MTS), iliac vein compression syndrome, also called Cockett syndrome, is a vascular disease caused by the compression of the left common iliac vein (LCIV) by the right common iliac artery (RCIA) against the lumbar vertebrae. This anatomical defect can lead to venous stasis especially in the left lower limb, and this increases the risk of deep venous thrombosis (DVT). Because routine screening is not standard practice, MTS frequently remains asymptomatic, and its prevalence is probably underestimated.
