Voltaren Gel should not be used by patients with known hypersensitivity to diclofenac. It also should not be used by patients who developed asthma, urticaria, or allergic reactions after taking aspirin or NSAIDs.
Biliary drainage is performed with a tube or catheter (called a biliary drain, biliary stent or biliary catheter) by a surgeon or, commonly, an interventional radiologist. It can be used to relieve a blockage in the bile duct, either permanently or as a temporary solution before definite treatment such as surgery.
Cerebral and cerebellar veins also drain into the superior petrosal sinuses. The inferior petrosal sinuses, where cerebellar, internal ear and brainstem veins drain, assist in draining the cavernous sinus but they drain directly into the internal jugular veins. The inferior petrosal sinuses are joined together by the basilar sinuses which lie posterior to the sella turcica on the sphenoid bone.
