Is inferior petrosal sinus sampling safe?
Background and purpose: Inferior petrosal sinus sampling (IPSS) is a useful diagnostic technique in adrenocorticotropic hormone (ACTH)-dependent hypercortisolism with normal or equivocal MR imaging. The procedure is believed to be safe, with mostly minor complications.
What is the inferior petrosal sinus?
The inferior petrosal sinus is one of the dural venous sinuses. Along with the cavernous sinus, it receives tributaries from the medulla oblongata, pons, and inferior surface of the cerebellum as well as labyrinthine veins (via the cochlear canaliculus and the vestibular aqueduct).
What is IPSS procedure?
Inferior petrosal sinus sampling (IPSS) is an invasive procedure in which adrenocorticotropic hormone (ACTH) levels are sampled from the veins that drain the pituitary gland; these levels are then compared with the ACTH levels in the peripheral blood to determine whether a pituitary tumor (as opposed to an ectopic …
Where is the inferior petrosal sinus?
The inferior petrosal sinus (sinus petrosus inferior) is situated in the inferior petrosal sulcus formed by the junction of the petrous part of the temporal with the basilar part of the occipital.
What is sinus confluence?
The confluence of sinuses (torcular herophili, or torcula) is the connecting point of the superior sagittal sinus, straight sinus, and occipital sinus. It is found deep to the occipital protuberance of the skull. Blood arriving at this point then proceeds to drain into the left and right transverse sinuses.
Are there any side effects to inferior petrosal sinus sampling?

Why do I need an inferior petrosal sinus test?
Your doctor has recommended that you have an Inferior Petrosal Sinus Sampling (IPSS) test. You have been diagnosed with Cushing’s syndrome, a condition whereby your body produces excessive amounts of cortisol hormone. Cortisol is produced by the adrenal glands which sit above the kidneys.
Which is no smoking Trust inferior petrosal sinus sampling ( IPSS )?

How is basal sampling of the petrosal sinus done?
Both tubes need to be labelled, then the EDTA tube centrifuged, separated and frozen before transport to the laboratory. Repeat this basal sampling after 15 minutes, and label t= 0 minutes. The radiologist will then perform selective venous sampling of the petrosal sinuses, via a femoral puncture.
