Little work has been done to consider the temperature changes and energy transfer that occur in the tissue outside the vein with ultrasound-guided vein ablation therapy. In this experiment, a Ex-Vivo model of the human calf was used to analyze heat transfer and energy degradation in tissue surrounding the vein during endovascular radiofrequency ablation (RFA). A clinical vein ablation protocol was used to determine the tissue temperature distribution in 10 per cent agar gel. Heat energy from the radiofrequency catheter was measured for 140 seconds at fixed points by four thermometer probes placed equidistant radially at 0...

Terminal branches of the superficial fibular nerve are at risk of iatrogenic damage during foot surgery, including hallux valgus rigidus correction, bunionectomy, cheilectomy, and extensor hallucis longus tendon transfer. One terminal branch, the dorsomedial cutaneous nerve of the hallux, is particularly at risk of injury at its intersection with the extensor hallucis longus tendon. Iatrogenic injuries of the dorsomedial cutaneous nerve of the hallux can result in sensory loss, neuroma formation, and/or debilitating causalgia...

Intrauterine growth restriction is a prevalent disease in pregnancy in which placental insufficiency leads to 5 to 10 times higher mortality and lifelong morbidities. The current detection rate is poor, and recently, ultrasound strain elastography (USEL) was proposed as a new diagnostic technique. Currently, placental USEL uses maternal subcutaneous fat as the reference layer, but this is not ideal as fat tissue stiffness can vary widely between subjects. Current USEL also uses manual palpation, and under different compression depths and rates, viscoelastic tissues such as placenta can yield different stiffness results...

The surgical technique with duodeno- duodenal enteroanastomosis of pancreas transplants allows for representative endoscopic ultrasound guided needle biopsies of the donor duodenum and the pancreas graft. We assessed whether histological findings in transplanted donor duodenal biopsies can indicate rejection in the transplanted pancreas. From September 2012, a duodeno-duodenal enteroanastomosis has been default technique for pancreas transplantations at our center. In 67 recipients we prospectively examined 113 endoscopic ultrasound- guided procedures with representative biopsies from the duodenum- and the pancreas grafts (97 per protocol and 16 on indication)...

Pancreatic cancer accounts for approximately 3% of all cancers in US, and is the fourth leading cause of mortality in both men and women. It is a silent killer due to lack of early symptoms and the majority of patients present at advanced stage at the time of initial diagnosis. Only 15-20% of patients are candidates for curative resection and even then, the 5-year survival rates range from 10-25%. Despite recent advances in the treatment of advanced pancreatic cancer, the prognosis remains grim with 5-year overall survival (OS) of approximately 10%...

PURPOSE: There is currently a lack of universally accepted criteria for gastrointestinal (GI) failure or dysfunction in critical care. Also, the clinical assessment of intestinal function is notoriously difficult and thus often goes unrecognized, contributing to poor outcomes. A recent grading system has been proposed to define acute gastrointestinal injury (AGI) in conjunction with other organ function scores (e.g., SOFA). Ultrasonography has become widely accepted as a diagnostic tool for GI problems and pathology...
