The steady progess in the armamentarium of techniques available for endovascular treatment of intracranial aneurysms requires affordable and reproducable experimental animal models to test novel embolization materials such as stents and flow diverters. The aim of the present project was to design a safe, fast, and standardized surgical technique for stent assisted embolization of saccular aneurysms in a rat animal model. Saccular aneurysms were created from an arterial graft from the descending aorta.The aneurysms were microsurgically transplanted through end-to-side anastomosis to the infrarenal abdominal aorta of a syngenic male Wistar rat weighing >500 g...

Conventionally, nasotracheal intubation has consisted of blind nasal passage and external manipulation of the tube through the glottis ('conventional technique'), a technique associated with a high incidence of nasal trauma. We evaluated a novel technique for routine asleep (i.e. post-induction) nasotracheal intubation using a bougie ('bougie technique'), which uses a nasopharyngeal airway to guide a paediatric bougie nasotracheally for use as a Seldinger tracheal intubation guide. Two hundred and fifty-seven older children (> 8 years) and adults were randomly assigned to videolaryngoscopy-assisted nasotracheal intubation using either the conventional or the bougie technique...

Objective Axillary artery cannulation is still regarded with distrust by surgeons because the artery is supposed to be fragile, difficult to access, and its cannulation is often considered time-consuming. This study was carried out to assess our results in a series of patients, using a simplified surgical approach to axillary artery cannulation. Methods Data were collected retrospectively from our prospective database. All patients operated on in our department between January 2004 and October 2016 and scheduled for various cardiac procedures with direct axillary artery cannulation were included in this study...

INTRODUCTION AND AIM: Surgical vasectomy remains the gold standard for fertility control in men. Endoluminal occlusion of the seminal ducts, thus avoiding an external incision, may become an appealing alternative to this approach. As our group has shown, nontraumatic endoscopic inspection of the seminal ducts is feasible in the human cadaver. We investigated the feasibility and reliability of occlusion using several commercially available medical sealing agents in the porcine vas deferens (VD)...

In pigs, the deep location of the common carotid artery and overlying sternomastoideus muscle in the neck has led to the recommendation for a surgical cutdown for common carotid access, as opposed to minimally invasive techniques for vascular access. We sought to determine if direct percutaneous common carotid artery access in piglets is attainable. Seventeen piglets were anesthetized and intubated. Under two-dimensional and color flow Doppler ultrasound guidance, a 21 gauge needle was utilized to access the right common carotid artery...

The majority of peripherally inserted central catheters (PICCs) are currently inserted with the aid of ultrasound guidance in the middle third of the upper arm. A growing patient population is presenting with challenging vessel access requiring placement of the PICC in the high upper third of the arm. To avoid this suboptimal exit site, a subcutaneous tunneling of the PICC is established away from the axilla to a more appropriate skin exit site. A prospective evaluation was performed in a single facility for all PICC placements from September 2014 to June 2015...

OBJECTIVES: Over 30% of critically ill patients on positive-pressure mechanical ventilation have difficulty weaning from the ventilator, many of whom acquire ventilator-induced diaphragm dysfunction. Temporary transvenous phrenic nerve pacing using a novel electrode-bearing catheter may provide a means to prevent diaphragm atrophy, to strengthen an atrophied diaphragm, and mitigate the harms of mechanical ventilation. We tested the initial safety, feasibility, and impact on ventilation of this novel approach...

OBJECTIVE: The primary objective was to compare the frequency of first-attempt successful axillary vein cannulation by the Seldinger technique using out-of-plane ultrasound guidance versus in-plane imaging. Between the two ultrasound imaging planes, this study also compared the number of attempts that were necessary for the cannulation of the left axillary vein along with the number of needle redirections that had to be done for final cannulation of the vein. Incidence of complications and the number of times the procedure was abandoned also were compared between the two imaging planes...

Introduction Preoperative assessment of vertebral artery (VA) is important to avoid its injury during surgery at craniovertebral junction (CVJ). The main concern is the course of third segment of VA (V3) while performing instrumentation at CVJ, that is, segment of VA from its course through transverse foramen of C2 to its course along the posterior arch of C1. This segment of VA includes its passage through C1 transverse foramen as well. This observational study was done to analyze the course, curvature, and termination of VA in patients with occipital assimilation of atlas at CVJ, a complex congenital anomaly, and compared with the normal course for better understanding especially by young neurosurgeons and spine surgeons...

BACKGROUND: Ultrasound-guided cannulation of deep mid-arm veins by a modified Seldinger (US-Seldinger) technique has been demonstrated to yield better puncture success rates and lower postoperative complication rates than direct cannulation of superficial veins near the elbow with a short peripheral cannula and peripherally inserted central catheter (PICC) insertion through the cannula (non-US conventional method). Economic factors have been evaluated across different operators (i.e. nurses, radiologists, and general practitioners) and different venous catheter types (i...

Spondylodiscitis is an inflammation of the intervertebral disc and the adjacent vertebral bodies. The spondylodiscitis can not only be a complication of medical interventions such as an operation near spinal column but also urogenital and vascular interventions and intravenous catheter use. A 71-year-old man was admitted to our emergency department with fever and severe abdominal pain. Antibiotic therapy had been performed with intravenous administration of 2 g of ceftriaxone and the patient underwent the placement of a percutaneous nephrostomy according to Seldinger technique...

REVIEW
Joseph T Church, Marcus D Jarboe
Vascular access procedures are an important and frequent component of the day-to-day practice of the pediatric surgeon. Most access procedures can be performed percutaneously via Seldinger or modified Seldinger technique and are aided by technology, such as ultrasound and fluoroscopy. Complications, such as infection, do occur, and the pediatric surgeon should be able to diagnose and treat these when they arise. The indications, techniques, and complications of vascular access are covered in this article.
