Using abdominal skin flaps in experimental rats, we created flaps that exhibited relatively constant necrosis in the distal side. The existence of arterial inflow had a marked effect on the survival of the distal part of these flaps. We postulate that the so-called delay mechanism produces the arterial inflow as a consequence, although how this occurs is still unsolved. We suggest the possibility that a large flap may be transposed in one stage with vascular anastomosis in the distal part--preferably artery and vein, or artery only.

Background: Right ventricular restrictive physiology (RVRP) is a common occurrence in repaired tetralogy of Fallot (rTOF). The relationship of RVRP with biventricular blood flow components and kinetic energy (KE) from 4-dimensional (4D) flow cardiovascular magnetic resonance (CMR) is unclear.

Objectives: The purpose of this study was to investigate the association of 4D flow CMR parameters with RVRP in rTOF patients.

Celiac trunk angiography with balloon occlusion of splenic artery for diagnosis and treatment of splenic steal syndrome.

Radiol Case Rep

March 2025

University of Maryland School of Medicine, Department of Diagnostic Radiology and Nuclear Medicine, Division of Vascular and Interventional Radiology, Baltimore, MD, USA.

Splenic steal syndrome (SSS) post liver transplant is a potential cause of graft dysfunction in the setting of peripheral hepatic arterial bed resistance and redirection of blood flow to a dominant splenic artery resulting in reduction of hepatic arterial inflow. We report utilization of balloon occlusion of the proximal splenic artery as an objective measure to confirm the diagnosis of SSS in a patient with orthotopic liver transplant followed by successful treatment with proximal splenic artery embolization using Gelfoam and Amplatzer vascular plug. Written informed consent for the publication of this case report was obtained from the patient.

Systemic artery-to-pulmonary artery fistula (SAPAF) is an uncommon abnormal vascular connection between systemic and pulmonary arteries. SAPAF with 3 or more inflow vessels has rarely been reported. The definitive diagnosis is made by selective arterial angiography, but 3-dimensional computed tomography angiography is useful for delineating abnormal vessels.

Norepinephrine-mediated slow vasomotion drives glymphatic clearance during sleep.

Cell

January 2025

Center for Translational Neuromedicine, University of Copenhagen, 2200 Copenhagen N, Denmark; Center for Translational Neuromedicine, University of Rochester, Rochester, NY 14627, USA. Electronic address:

As the brain transitions from wakefulness to sleep, processing of external information diminishes while restorative processes, such as glymphatic removal of waste products, are activated. Yet, it is not known what drives brain clearance during sleep. We here employed an array of technologies and identified tightly synchronized oscillations in norepinephrine, cerebral blood volume, and cerebrospinal fluid (CSF) as the strongest predictors of glymphatic clearance during NREM sleep.

Background: Hepatic artery infusion pump (HAIP) chemotherapy is a locoregional treatment for intrahepatic malignancies. HAIPs are surgically implanted, and the catheter tip is typically inserted into a ligated gastroduodenal artery stump. Potential complications at the catheter insertion site include dehiscence, pseudoaneurysm or extravasation, and adjacent hepatic arterial stenosis and thrombosis.
