Ultrasound-Guided Radiofrequency Denervation of the Medial Calcaneal Nerve.

Objective: Plantar fasciosis is a common complaint of athletes, particularly for runners. The medial calcaneal nerve (MCN) may play a role in the pain syndrome, and radiofrequency (RF) denervation has been previously reported. The hypothesis is that ultrasound-guided denervation of the MCN results in symptomatic improvement.

Percutaneous Recanalization of Iliac Artery Occlusions by Radiofrequency Perforation: Initial Experience.

The success rate of endovascular therapy for iliac occlusions is often limited by failure to traverse the lesion. A single institution's experience with the use of radiofrequency-assisted recanalization of occlusions in 10 iliac arteries is described. The median length of occlusion was 43 mm (range, 14-64 mm; mean, 42 mm).

Pattern of Fascicular Involvement in Midportion Achilles Tendinopathy at Ultrasound.

Background: The Achilles tendon is composed of fascicles from the soleus and gastrocnemius muscles, which are identifiable as discrete components at anatomical dissection.

Hypothesis: The pattern of fascicular involvement in Achilles tendinopathy may be characterized at ultrasound, and this characterization is reliable between different observers.

Study Design: Cross-sectional diagnostic study.

Frequency of acute kidney injury following intravenous contrast medium administration: a systematic review and meta-analysis.

Purpose: To perform a systematic review and meta-analysis of controlled studies examining the incidence of acute kidney injury (AKI) and other outcomes in patients exposed to intravenous (i.v.) contrast medium compared with patients who underwent an imaging examination without contrast medium or were otherwise unexposed (control group).

Return to competitive play after hamstring injuries involving disruption of the central tendon.

Background: The hamstring muscles are the most commonly injured muscle group in many different sports. Recovery time is often unpredictable and prolonged, and recurrent injury is common.

Hypothesis: Hamstring injuries that disrupt the central tendon enclosed within the muscle belly require a longer recovery time than do injuries involving only muscle, epimysial fascia, or the musculotendinous junction.

The prevalence and clinical significance of sonographic tendon abnormalities in asymptomatic ballet dancers: a 24-month longitudinal study.

Introduction: Sonographic abnormalities of the achilles and patellar tendons are common findings in athletes, and tendinopathy is a common cause of pain and disability in athletes. However, it is unclear whether the sonographic changes are pathological or adaptive, or if they predict future injury. We undertook a cohort study to determine what sonographic features of the achilles and patellar tendons are consistent with changes as a result of ballet training, and which may be predictive of future development of disabling tendon symptoms.

Radiofrequency denervation of the inguinal ligament for the treatment of 'Sportsman's Hernia': a pilot study.

Background: Chronic groin pain is a common and debilitating condition in highly active athletes. Symptoms are often ascribed to the so-called Sportsman's Hernia, and these patients frequently undergo prolonged and often painful remedial physiotherapy, or, if the condition is refractory, surgery to repair the posterior inguinal wall.

Hypothesis: We hypothesised that radiofrequency denervation (RFD) of both the ilioinguinal nerve and inguinal ligament could be used to desensitise the groin region and enable the athlete to become pain-free.

AMPLATZER Vascular Plug 4 for proximal splenic artery embolization in blunt trauma.

A consecutive case series was conducted evaluating proximal splenic artery embolization (SAE) with the AMPLATZER Vascular Plug 4 (AVP4) (St. Jude Medical, Inc, St. Paul, Minnesota) in eight patients with high-grade splenic trauma.

Imaging assessment of congenital and acquired abnormalities of the portal venous system.

Abnormalities of the portal venous system are a heterogeneous group of conditions that can cause substantial morbidity and mortality and may lead to complications during surgery or percutaneous interventions involving the portal venous system. High-resolution computed tomography, ultrasonography, and magnetic resonance imaging permit a comprehensive, noninvasive evaluation of the portal venous system, enabling the detection of both structural and functional abnormalities. However, an understanding of the embryologic development of the normal portal venous anatomy and anatomic variants is essential to accurately interpret the imaging findings.

Percutaneous cystic duct stent placement in the treatment of acute cholecystitis.

Percutaneous cholecystostomy is well established as a temporising treatment option in selected patients presenting with acute cholecystitis. However, some patients who undergo cholecystostomy will have persistent discharge, which precludes catheter removal, or may not be medically suitable for future cholecystectomy. In these circumstances, percutaneous cystic duct stenting isa novel treatment option.
