OBJECTIVES: The aim of this study was to assess the safety and effectiveness of our selective antegrade brain perfusion (SABP) strategy, which is characterized by moderate hypothermic and low-pressure management under pH-stat using a completely closed cardiopulmonary bypass circuit with a single centrifugal pump. METHODS: Forty-nine consecutive patients (median age, 74) underwent total aortic arch replacement using a 4-branched graft. SABP was conducted with individual cannulation in all arch vessels...

Background and aim The purpose of this study was to assess incidence, predictors and outcome of radial artery occlusion (RAO) after transradial catheterization (TRC) based on clinical and Doppler ultrasound study. Methods A total of 1,945 consecutive patients undergoing transradial catheterization for diagnostic evaluation or intervention were included. Radial artery examination was based on palpation and colour Doppler study on the day before, 1 day (D1), 1 month (D30) and 6 months (D180) following the procedure...

BACKGROUND: Preclinical neuroimaging allows for the assessment of brain anatomy, connectivity and function in laboratory animals, such as mice and rats. Most of these studies are performed under anesthesia to avoid movement during the scanning sessions. METHOD: Due to the limitations associated with anesthetized imaging, recent efforts have been made to conduct rodent imaging studies in awake animals, habituated to the restraint systems used in these instances. As of now, only one such system is commercially available for mouse scanning (Animal Imaging Research, Boston, MA, USA) integrating the radiofrequency coil electronics with the restraining element, an approach which, although effective in reducing head motion during awake imaging, has some limitations...

Stabilization of pelvic ring injuries and certain acetabular fractures using percutaneous techniques is becoming increasingly more common. Intramedullary superior ramus screw fixation is beneficial in both injury types. While implants can be placed in an antegrade or retrograde direction, parasymphyseal ramus fractures benefit from retrograde implant insertion. In some patients, the parabolic osseous anatomy or obstructing soft tissues of the anterior pelvis or thigh can prevent appropriate hand and instrumentation positioning for appropriate retrograde ramus screw insertion through the entire osseous fixation pathway...

OBJECTIVES: Axillary artery cannulation has been used as an alternative site for cardiopulmonary bypass during surgery for aortic dissections and aneurysmal disease of the ascending aorta and arch. This study reports our experience with reusing the axillary artery for cardiopulmonary bypass during complex aortic and cardiac surgical procedures.

OBJECTIVE: Petrosal venous prolactin concentrations have been promoted to improve the diagnostic accuracy of inferior petrosal sinus sampling (IPSS), beyond that achieved with ACTH measurement alone, in diagnosing a pituitary ACTH source, and determining corticotrophinoma side (L/R). Our objective was to assess the effect of using prolactin to confirm adequacy of petrosal cannulation in a cohort of patients with ACTH-dependent Cushing's syndrome. DESIGN: Retrospective cohort study...

BACKGROUND: In patients without or with injured cephalic vein, using the basilic vein for creating arteriovenous fistula (AVF) is the best way for hemodialysis. In order to create AVF, the basilic vein should be superficialized and lateralized. This study sought to examine outcome of relocation of basilic vein in brachiobasilic fistulas in patients with chronic renal failure (CRF). METHODS: We evaluated the outcome of creation of brachiobasilic fistula with transposition of basilic vein in 27 patients (14 males and 13 females with mean age of 60...

BACKGROUND: Hemodialysis arteriovenous fistulas (AVFs) are suboptimally used primarily due to problems with maturation, early thrombosis, and patient nonacceptance. An endovascular approach to fistula creation without open surgery offers another hemodialysis vascular access option. STUDY DESIGN: Prospective, single-arm, multicenter study (Novel Endovascular Access Trial [NEAT]). SETTINGS & PARTICIPANTS: Consecutive adult non-dialysis-dependent and dialysis-dependent patients referred for vascular access creation at 9 centers in Canada, Australia, and New Zealand...

PURPOSE: To compare one year outcomes of illuminated microcatheter-assisted circumferential trabeculotomy(IMCT) vs conventional partial trabeculotomy(CPT) for Primary Congenital Glaucom (PCG). DESIGN: Randomized clinical trial METHODS: Forty eyes of 31 patients with unilateral or bilateral primary congenital glaucoma aged less than two years were randomized to undergo IMCT (20 eyes) or CPT (20 eyes). Primary outcome measure was IOP reduction. The success criterion was defined as intraocular pressure (IOP) ≤ 12 mm Hg without and with anti-glaucoma medications (absolute success and qualified success respectively)...

BACKGROUND: Simulation is quickly becoming vital to resident education, but commercially available central line models are costly and little information exists to evaluate their realism. This study compared an inexpensive homemade simulator to three commercially available simulators and rated model characteristics. MATERIALS AND METHODS: Seventeen physicians, all having placed >50 lines in their lifetime, completed blinded central line insertions on three commercial and one homemade model (made of silicone, tubing, and a pressurized pump system)...

OBJECTIVE: The objective of this study was to characterize the technique and to report the results of double prepuncture used during complex radiofrequency ablation (RFA) in cases of treating multiple incompetent veins or encountering focal obstruction to catheter advancement. METHODS: A double prepuncture technique was applied in patients requiring endovascular ablation of multiple veins and patients with great saphenous vein cannulation failure. We treated 13 limbs in 12 patients during a 24-month period with RFA in which the double prepuncture technique was used...

PURPOSE: The aim of this study was to investigate the validity of the dynamic compression principle of tension band wiring in two techniques for patella fracture treatment. METHODS: Twelve human cadaveric knees with simulated transverse patella fractures were assigned to two groups for treatment with tension band wiring using either Kirschner (K-) wires or cannulated screws. Biomechanical testing was performed over three knee movement cycles between 90° flexion and 0° full extension...

We report a rare complication of right brachiocephalic vein perforation during ultrasound-guided cannulation of the right internal jugular vein (IJV) in a patient with a tortuous common carotid artery (CCA). We suspect that the tortuous CCA displaced the IJV, which caused misplacement of the J-tip guidewire into the subclavian vein. The stiff dilator sheath introduced over the guidewire then perforated the wall of the brachiocephalic vein, causing massive hemothorax. This was diagnosed by videothoracoscopy...

Endovascular redo aortic operations are a challenging undertaking. Techniques for treatment date almost as far back as the original open repair itself. Risk factors for failure following aortic repair include larger AAA necks, severe neck angulation, as well as clinical variables such as age, family history, obesity and chronic obstructive pulmonary disease. The armamentarium of endovascular treatments is vast and increasing. Aside from provisional embolization of endoleaks or deferment to open repair conversion, attention should be directed toward obtaining adequate proximal and distal sealing...

Osteogenesis imperfecta (OI) is a bone disorder that can lead to skull base deformities such as basilar invagination, which can cause compression of cranial nerves, including the trigeminal nerve. Trigeminal neuralgia in such cases remains a challenge, given distorted anatomy and deformities. We present an alternative option, consisting in cannulation of the foramen ovale and classical percutaneous treatment. Percutaneous balloon microcompression was performed in a 28 year-old woman with OI and severe trigeminal neuralgia using computed tomography (CT) and radiographic-guided cannulation of the Gasserian ganglion without neuronavigation or stereotactic devices...

Jung A Lim, Chan Hee Jee, Kyung-Hwa Kwak
RATIONALE: The misplacement of central venous catheter (CVC) can occur more often at the left jugular vein than the right side due to anatomic differences. And many of the previously reported cases are about catheter misplacement resulting from vessel penetration associated with guidewire. This case differs that the catheter itself through the sheath introducer can cause venous injury that may lead to the malposition of CVC particularly through an approach to the left internal jugular vein...
