: Local anaesthetic injection between the tibial and commmon peroneal nerves within connective tissue sheath results in a predictable diffusion and allows for a reduction in the volume needed to achieve a consistent sciatic popliteal block. Using 3D ultrasound volumetric acquisition, we quantified the visible volume in contact with the nerve along a 5cm segment. METHODS: We included 20 consecutive patients scheduled for bunion surgery. Ultrasound guided popliteal block was performed using a posterior, out of plane approach at the level of división of the sciatic nerve...

The practice of regional anaesthesia is rapidly changing with the introduction of ultrasound into the working domain of the anaesthesiologist. New techniques are being pioneered. Among the recent techniques, notable are the truncal blocks, for example, the transversus abdominis plane block, rectus sheath block, hernia block and quadratus lumborum block in the abdomen and the pectoral nerves (Pecs) block 1 and 2, serratus anterior plane block and intercostal nerve block. This narrative review covers the brief anatomical discourse along with technical description of the ultrasound-guided truncal blocks...

Distal biceps tendon (DBT) ruptures are infrequent injuries that result in pain, weakness, and cosmetic deformity. Severe retraction of the ruptured DBT can occur at the time of injury, or in chronic neglected ruptures, and surgical exposure is performed using a single incision or a 2-incision technique. The technique presented here describes an endoscopic approach using 3 portals that provide access to the retracted DBT, biceps sheath, and radial tuberosity. Preoperative sonographic localization of the retracted DBT and neurovascular structures is used to guide portal placement...

BACKGROUND: While the uptake of transradial access site is growing, there are concerns about associated radial injury. We report a feasibility study of a technique that enables both 5Fr diagnostic and PCI cases to be undertaken without an arterial sheath using conventional diagnostic and guide catheters with a modified balloon assisted tracking (BAT) technique. METHODS: We performed a prospective single center pilot study to assess the feasibility and effectiveness of sheathless radial artery access and BAT to perform coronary angiography and angioplasty using conventional 5 Fr diagnostic and guide catheters...

The standard technique of catheter closure of patent ductus arteriosus (PDA) may be associated with arterial complications particularly in small pediatric patients. The aim of this study was to evaluate whether catheter closure of PDA in small children using an exclusive venous approach is a safe and effective alternative to closure with the standard technique. One hundred-twelve patients, aged 2 to 24 months, were randomly assigned in a 1:1 ratio to catheter closure of PDA using the standard technique (group 1) and an exclusive venous approach (group 2), respectively...

A sheathless system that inserts a catheter directly into the artery can reduce puncture site-related complications through a 2-Fr reduction of the outer diameter. However, the gap between the dilator and the guiding catheter of the sheathless system is larger than the gap between the dilator and sheath of the introducer system, resulting in stronger insertion resistance. A twisting method with rapid alternating rotation of a device to the left and right during insertion can reduce the insertion resistance...

Although heparin administration has reduced the incidence of radial artery occlusion (RAO) during the transradial coronary angiography (TRCA), the effective activated clotting time (ACT) value for guiding unfractionated heparin dosing in patients undergoing TRCA is unknown. Four hundred thirty-two patients who were scheduled for elective TRCA were enrolled in our prospective study. All the patients received a standard dose of 5,000 IU unfractionated heparin. Anticoagulation level was assessed by ACT measurements that were taken at the end of the procedure just before the sheath removal...

OBJECTIVE Endoscopic removal of intracerebral hematomas is becoming increasingly common, but there is no standard technique. The authors explored the use of a simple image-guided endoscopic method for removal of spontaneous supratentorial hematomas. METHODS Virtual reality technology based on a hospital picture archiving and communications systems (PACS) was used in 3D hematoma visualization and surgical planning. Augmented reality based on an Android smartphone app, Sina neurosurgical assist, allowed a projection of the hematoma to be seen on the patient's scalp to facilitate selection of the best trajectory to the center of the hematoma...

Fibrous scaffolds have shown promise in tissue engineering due to their ability to improve cell alignment and migration. In this paper, poly(ε-caprolactone) (PCL) fibers are fabricated in different sizes using a microfluidic platform. By using this approach, we demonstrated considerable flexibility in ability to control the size of the fibers. It was shown that the average diameter of the fibers was obtained in the range of 2.6-36.5 μm by selecting the PCL solution flow rate from 1 to 5 μL min(-1) and the sheath flow rate from 20 to 400 μL min(-1) in the microfluidic channel...

OBJECTIVES: Biceps tendinitis is a source of anterior shoulder pain and is amenable to therapeutic injection. Studies have shown greater accuracy with image-guided compared to unguided injection of the biceps tendon sheath. There is no literature comparing ultrasound-guided to fluoroscopy-guided biceps tendon sheath injection. The purpose of this study was to compare clinical outcomes, complication rates, procedure success rates, and financial costs of the two imaging-guided methods. METHODS: A 10-year retrospective review of the picture archiving and communication system was performed to identify patients who underwent image-guided proximal biceps tendon sheath injection...

BACKGROUND: Urinary stones disease is becoming more common not only in adults but also in children. Most cases are resolved with extracorporeal shock wave lithotripsy, but miniaturization of endoscopes has increased the use of ureteroscopy in resolving ureteral stones, most notably in children. CASE PRESENTATION: This presentation focuses on two cases of microureteroscopy. In both cases, the presence of lithiasis in the pelvic ureter was suspected to be the cause of ureter hydronephrosis, and a microureteroscopy was performed for treatment purposes...
