The diagnosis of radicular pain secondary to Piriformis Muscle Syndrome has been historically difficult due to lack of accurate means to identify and selectively inject the piriformis muscle. This paper describes a simple and reproducible technique to safely inject the piriformis muscle, using a combination of fluoroscopic guidance and a standard neuro-muscular stimulator.

This article describes a safe and easy method to position a tracheoesophageal catheter correctly. The procedure is carried out under fluoroscopic guidance and requires neither general nor local anesthesia. The only modification necessary was removal of the tip of the hollow rubber catheter, to create an opening through which the guide wire could be passed.

When used in veterinary medicine, central venous catheters are typically inserted through the external jugular vein, with their caudal extension within the cranial vena cava. Radiographic or fluoroscopic guidance is recommended to assist in correctly placing these catheters. This article provides radiologic examples of common central venous catheter malpositions and complications.

Guidewire-associated complications that occur during the process of central venous catheterization include its kinking, looping, knotting and breakage. The removal of a looped or knotted guidewire is problematic because it can cause vessel damage, major hemorrhage, or embolization of a fractured guidewire. We report a case of guidewire kinking and its successful removal under fluoroscopic guida...

Vascular malformations of bone are complex lesions that can cause deformity and pain. A combined soft tissue and intraosseous venous malformation of the left thumb in a girl was treated with two sessions of ethanol sclerotherapy using a bone marrow aspiration needle under fluoroscopic guidance.
