AIM To describe an approach to anterior cruciate ligament (ACL) reconstruction using autologous hamstring by drilling via the anteromedial portal in the presence of an intramedullary (IM) femoral nail. METHODS Once preoperative imagining has characterized the proposed location of the femoral tunnel preparations are made to remove all of the hardware (locking bolts and IM nail). A diagnostic a...

BACKGROUND Self-expanding metal stents (SEMS) are widely used to palliate patients with oesophageal cancer. Placement is usually done under endoscopic and fluoroscopic guidance. We have developed an exclusively endoscopic technique to deploy these stents. This article documents the technique and periprocedural experience. PATIENTS AND METHODS All patients who had SEMS placement for oesophagea...

STUDY DESIGN Randomized laboratory cadaver study. OBJECTIVE The objective of this study was to determine the accuracy of anterior transpedicular screw placement in the cervical spine using conventional fluoroscopy versus computer-assisted navigation. SUMMARY OF BACKGROUND DATA Traditionally, global cervical instability has required anterior and posterior fixation due to the superior biomech...

scopic ultrasound−assisted rendezvous procedures has been reported previously in patients with obstructive chronic pan− creatitis [1 ± 5]. However, there have been no reports describing the use of this tech− nique in patients with normal pancreatic duct dimensions. We present two patients, a 42−year−old woman with a history of recurrent acute pancreatitis and a tight, inaccessible pan− creatic ...

Of patients presenting to pain clinics, complaints are of low back or buttock pain with or without radicular leg symptoms is one of the most common. Piriformis syndrome may be a contributor in up to 8% of these patients. The mainstay of treatment is conservative management with physical therapy, anti-inflammatory medications, muscle relaxants, and correction of biomechanical abnormalities. Howe...

Surgical embolectomy is widely used to treat massive or submassive pulmonary thromboembolism and chronic thromboembolic pulmonary hypertension [1]-[3]. However, recently a new minimally invasive transvenous approach to clot evacuation using the AngioVac aspiration system (Vortex Medical, Norwell, Massachusetts) such as AngioVac aspiration system has been successfully used for retrieval of right...

Introduction Orthopedic interventions are often performed using x-ray fluoroscopic guidance. Although boney structures can be seen on fluoroscopic images, soft tissue contrast in such images is poor. In addition, fluoroscopy can only provide 2-dimensional projection images, which has no spatial resolution along the projection axis. For these reasons it would be beneficial to use preoperative 3D...

Modern fluoroscopes used for image-based guidance in interventional procedures are complex X-ray machines, with advanced image acquisition and processing systems capable of automatically controlling numerous parameters based on defined protocol settings. This study evaluated and compared approaches to technique factor modulation and air kerma rates in response to simulated patient thickness var...

Multimodality imaging in the cardiac catheterization laboratory continues to develop with rapid advancements in the use of intracardiac echocardiography (ICE), 3D echocardiography (3DE) and multidetector computed tomography (MDCT), with fluoroscopic overlay to produce 3D images of intracardiac structures. The improvement in these imaging tools have coincided with innovation and procedural advan...
