Venous subarachnoid hemorrhage after inferior petrosal sinus sampling for adrenocorticotropic hormone.

چکیده
Neurologic complications associated with inferior petrosal sinus sampling for adrenocorticotropic hormone in the diagnosis of Cushing syndrome are rare. Previously reported complications include brain stem infarction and pontine hemorrhage. We report a case of venous subarachnoid hemorrhage with subsequent acute obstructive hydrocephalus occurring during inferior petrosal sinus sampling for Cushing syndrome.

Adrenocorticotropic hormone-dependent Cushing's syndrome: sensitivity and specificity of inferior petrosal sinus sampling.
BACKGROUND AND PURPOSE Determining the cause of Cushing's syndrome can be difficult. Bilateral inferior petrosal sinus (IPS) sampling after ovine corticotropin-releasing hormone (oCRH) stimulation is an established technique for the differentiation of pituitary from nonpituitary sources of adrenocorticotropic hormone (ACTH) production. The purpose of this study was to review our experience to d...
متن کاملThere is no simple answer to a rare complication of inferior petrosal sinus sampling.
Bilateral inferior petrosal sinus sampling is the most reliable test to differentiate Cushing’s disease from ectopic adrenocorticotropic hormone (ACTH) production. Catheters, whether preshaped polyethylene or coaxial Tracker systems, are supple and atraumatic. Retrograde venograms are gentle procedures performed only to document catheter position at the time of sampling. And yet, as reported by...
متن کاملBilateral sequential inferior petrosal sinus sampling with corticotrophin-releasing hormone stimulation in the diagnosis of Cushing's disease.
OBJECTIVE The demonstration of a central to peripheral ACTH gradient in a hypercortisolaemic patient is diagnostic of Cushing's disease. We tried to determine whether single blood samples for ACTH obtained sequentially from each of the inferior petrosal sinuses following human corticotrophin-releasing hormone (hCRH) stimulation can reliably establish such a gradient. DESIGN Prospective study....
متن کاملThe role of bilateral inferior petrosal sinus sampling in the diagnostic evaluation of Cushing syndrome.
Bilateral inferior petrosal sinus sampling is the gold standard diagnostic assay in identifying the pituitary source of adrenocorticotropic hormone secretion in Cushing syndrome. The noninvasive assays used in the workup of Cushing syndrome are often misleading or ambiguous, yielding sensitivities of up to only 80%. Inferior petrosal sinus sampling, however, is highly accurate a...
متن کاملBilateral Inferior Petrosal Sinus Sampling by Unilateral Femoral Venous Approach
PURPOSE Bilateral inferior petrosal sinus sampling (IPSS) is a direct method of distinguishing between pituitary and ectopic ACTH secretion. We present unilateral femoral route technique avoiding bilateral femoral venous puncture using two 4F catheters into both sides of IPSS in these obese patients. MATERIALS AND METHODS Unilateral femoral puncture using 9F guiding catheter allowed two 4F ca...
