Background: Surgical venous cutdown is a method for totally implantable venous access device (TIVAD) insertion. The main drawback of this technique is its higher failure rate when compared with the percutaneous approach, which is mostly related to anatomic variations of the cephalic vein. The aim of this study was to assess preoperative ultrasound imaging as a tool to predict cephalic vein cutdown failure for TIVAD insertion.
Methods: Ultrasound and operative reports of a cohort of patients undergoing TIVAD insertion by cephalic vein cutdown were reviewed. Ultrasound venous (vein visibility, diameter, length, subcutaneous depth, vein path, and subclavian junction visibility) and patient variables were tested by logistic regression as predictors of TIVAD insertion failure.
Results: One hundred sixty consecutive patients underwent cephalic vein cutdown for attempted TIVAD insertion. An inability to visualize the vein on the preoperative ultrasound examination (odds ratio, 4.39; 95% confidence interval, 1.57-12.30; P < .05) and depth of the vein (odds ratio, 1.07; 95% confidence interval, 1.00-1.15; P = .042) were predictors of failure of TIVAD insertion by cephalic vein cutdown.
Conclusions: Preoperative ultrasound examination allows identifying patients at risk of failure of TIVAD insertion by cephalic vein cutdown. Preoperative ultrasound examination constitutes an efficient tool for choosing the most appropriate surgical approach and improving patient comfort.

Purpose: The AVeNEW Post-Approval Study (AVeNEW PAS) follows upon results from the AVeNEW IDE clinical trial and was designed to provide additional clinical evidence of safety and effectiveness using the Covera™ Vascular Covered Stent to treat arteriovenous fistula (AVF) stenoses in a real-world hemodialysis patient population.
Materials And Methods: One hundred AVF patients were prospectively enrolled at 11 clinical trial sites in the USA and treated with the covered stent after angioplasty of a clinically significant target stenosis. The primary safety outcome was freedom from any adverse event that suggests the involvement of the AV access circuit evaluated at 30 days.
Laparoscopic liver resection utilizing the ventral avascular area of the inferior vena cava: A retrospective cohort study.

Background: Laparoscopic liver resection (LLR) can be challenging due to the difficulty of establishing a retrohepatic tunnel under laparoscopy. Dissecting the third hepatic hilum before parenchymal transection often leads to significant liver mobilization, tumor compression, and bleeding from the short hepatic veins (SHVs). This study introduces a novel technique utilizing the ventral avascular area of the inferior vena cava (IVC), allowing SHVs to be addressed after parenchymal transection, thereby reducing surgical complexity and improving outcomes in in situ LLR.

In order to provide some references for vein approach selection in adrenal vein sampling (AVS), this retrospective study analyzed 325 cases of primary aldosteronism (PA) patients who underwent AVS via the upper extremity vein approach, comparing the differences in complications and visual analogue scale (VAS) scores through median cubital vein (MCV), basilic vein (BV), and cephalic vein (CV). The results indicated no significant difference in the incidence of venous spasm (right MCV vs. right BV vs.

Introduction: Ultrasound (US)-guided axillary vein puncture is a safe and effective approach for cardiac implantable electronic device (CIED) implantation, and it is highly recommended by the current consensus document. However, only reports on small populations are available in the current literature regarding the comparison of this technique with other traditional approaches (subclavian vein blind puncture and cephalic vein surgical cutdown).
Purpose: We aimed to assess the effectiveness and safety of US- guided axillary vein puncture using a microintroducer kit for CIED implantation as compared to the aforementioned traditional approaches.
