The Bird's Nest inferior vena caval filter (Cook, Bloomington, Ind) has been approved for clinical use since 1989. The authors report two cases of cephalic migration of the filter. Both cases of migration occurred in association with a massive thromboembolism after placement of the filter. It appears that a massive thromboembolism can cause this filter to migrate cephalad. The authors suggest that there is potential for nonsurgical management of the migrated filter.

Fluid-structure interaction in a follow-up study of arterio-venous fistula maturation.
Sci Rep
November 2024
School of Mechanical and Manufacturing Engineering, University of New South Wales, Sydney, NSW, 2052, Australia.
Article Synopsis
- - Arteriovenous fistula (AVF) is the ideal vascular access for patients undergoing hemodialysis, created by surgically connecting an artery and vein, but research indicates that many do not function beyond a year.
- - This study utilized fluid-structure interaction (FSI) modeling to analyze non-Newtonian blood flow in a specific type of AVF over a 15-week and 1.5-year period, assessing both hemodynamic changes and wall alterations through ultrasound.
- - Key findings included the presence of counter-rotating vortices affecting pressure, different patterns of blood flow characteristics over time, minimal low-wall shear stress in healthy AVFs, and shifts in areas of maximum wall deformation as time
Early epidural lead migration in spinal cord stimulator trials: A case series.
Interv Pain Med
September 2024
Department of Anesthesiology, Pharmacology & Therapeutics, University of British Columbia, Vancouver, British Columbia, Canada.
Article Synopsis
- Spinal cord stimulation (SCS) trial periods often experience lead migration, which can negatively affect pain management outcomes for patients.
- Significant lead migration tends to happen early in the trial, specifically on postoperative days 1 or 2, suggesting that adjustments could be made to enhance therapeutic effectiveness.
- A study involving 27 patients revealed that 74% experienced clinically significant lead migration, with an average movement of around 18-19 mm shortly after implantation.
Trans-Oral Protrusion of the Distal End of a Ventriculoperitoneal Shunt: A Case Report of an Unusual Complication.
Glob Pediatr Health
October 2024
Winners Foundation, Yaounde, Cameroon.
Ventriculoperitoneal shunting (VPS) is the surgical technique of choice to manage pediatric hydrocephalus. Despite having good results, it is prone to complications, some of which are rare. This is the case report of a 2-year-old male, with an uncomplicated VPS done at 6 months of age, presenting with vomiting, irritability, anorexia, and drooling.

Background: The aspect of sexual differentiation and the mechanism controlling the position of genitalia, which represents one of the most substantial differences between the sexes, is still poorly understood. Minor cases and some variants of penoscrotal transposition (PST) are unreported, and obvious cases were classified broadly and confused with other unrelated anomalies.
Methodology: Relevant literature published till 2022 were reviewed then organized, recapitulated, and presented in comparison with the findings and data of 65 child diagnosed with PST.
Early Injury Landscape in Vein Harvest by Single-Cell and Spatial Transcriptomics.
Circ Res
June 2024
Department of Pediatrics, Emory School of Medicine, Atlanta, GA (M.E.M., M.B., B.E.T., S.S.B., M.K.B.).
Background: Vein graft failure following cardiovascular bypass surgery results in significant patient morbidity and cost to the healthcare system. Vein graft injury can occur during autogenous vein harvest and preparation, as well as after implantation into the arterial system, leading to the development of intimal hyperplasia, vein graft stenosis, and, ultimately, bypass graft failure. Although previous studies have identified maladaptive pathways that occur shortly after implantation, the specific signaling pathways that occur during vein graft preparation are not well defined and may result in a cumulative impact on vein graft failure.
