Comparison of Different Hemostatic Net Applications on Rat Dorsal Skin Flap Model.

Department of Histology and Embryology, Gazi University, Ankara, Türkiye.
Background: There are several articles discussing the use of a hemostatic net to close dead spaces, but no in-vivo experimental studies have simultaneously examined the histology and tissue perfusion of these techniques.
Objectives: Our aim is to compare variations of the hemostatic net technique commonly used in current practice.
Methods: Two different hemostatic net suturing techniques and two times of suture removal were tested, with a control group for comparison.
A novel technique for external iliac artery reconstruction in renal transplant patients with extensively atherosclerotic lower limb vasculature.

Department of Cardiovascular Surgery, Houston Methodist Hospital, Houston, TX.
We describe a 54-year-old man with type 2 diabetes mellitus, ischemic myopathy, pulmonary hypertension, and end-stage renal disease who was admitted for heart failure and listed for a dual cardiac-renal transplantation. Extensive calcification in the iliac arteries prevented clamping. Proximal endovascular balloon control of the left iliac artery was achieved using contralateral access; distal control was established by passing a Fogarty catheter distally through an iliac arteriotomy, later used for anastomosis of the cadaveric conduit.

Background And Purpose: In acute ischemic stroke, the amount of "local" CBF distal to the occlusion, i.e. all blood flow within a region whether supplied antegrade or delayed and dispersed through the collateral network, may contain valuable information regarding infarct growth rate and treatment response.

Background: Renal autoregulatory mechanisms modulate renal blood flow. Connecting tubule glomerular feedback (CNTGF) is a vasodilator mechanism in the connecting tubule (CNT), triggered paracrinally when high sodium levels are detected via the epithelial sodium channel (ENaC). The primary activation factor of CNTGF-whether NaCl concentration, independent luminal flow, or the combined total sodium delivery-is still unclear.

Department of Vascular Surgery, Sir Charles Gairdner Hospital, Perth, Australia.
A 2-day-old neonate was referred to the vascular surgery service owing to concerns of limb perfusion after entrapment of a microcatheter in the middle cerebral artery. The catheter was inserted via the umbilical artery to treat a vein of Galen arteriovenous malformation. This catheter inadvertently became entrapped owing to device failure, was cut at the insertion site, and left in situ for 3 months.
