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.
How is inferior petrosal sinus sampling done?
How do we do an IPSS procedure? Typically under general anesthesia, we place small tubes (catheters) into the femoral veins (the main vein draining the legs) at the level of the groin. From there, under X-ray guidance, we navigate those catheters to the main veins which drain the Pituitary gland.
Is petrosal sinus sampling painful?
Although the procedure is not painful, you may experience minor pain when the catheter (tubing) is passed through the veins. You may also experience pain at the puncture site. Petrosal sinus sampling is an invasive procedure where blood samples are taken from each side of the veins that drain into the pituitary gland.
Why does Cushing’s cause weight gain?
Cushing’s syndrome (hypercortisolism) happens when there’s extra cortisol in your body. Cortisol, the “stress hormone,” is vital to regulating your blood sugar and turning food into energy. Unfortunately, too much of it caused by a medication or a tumor can cause weight gain, muscle weakness and more.
How do you get Cushing’s?
Cushing syndrome occurs when your body has too much of the hormone cortisol over time. This can result from taking oral corticosteroid medication. Or your body might produce too much cortisol.
What is cyclical Cushing’s syndrome?
Cyclic Cushing’s syndrome (CS) is a rare disorder, characterized by repeated episodes of cortisol excess interspersed by periods of normal cortisol secretion. The so-called cycles of hypercortisolism can occur regularly or irregularly with intercyclic phases ranging from days to years.
How does Cushing’s cause obesity?
Central obesity in Cushing’s syndrome. Fat tissue redistribution in CS leads to central obesity and metabolic complications. Visceral obesity is associated to altered adipokine secretion further contributing to insulin resistance, inflammation and fat accumulation.
What causes Carney complex?
In many cases, Carney complex is due to mutations of the PRKAR1A gene. The mutation can occur randomly for no apparent reason (i.e., new mutation) or be inherited as an autosomal dominant trait. Carney complex is a different disorder from Carney triad.
Can Sheehan cause hypothyroidism?
In the present case, autoantibodies against different endocrine tissues were absent. Patients with hypothyroidism due to Sheehan’s syndrome may have unexpectedly normal or elevated TSH levels 2.
Can you have Cushing syndrome without a tumor?
Approximately 10 to 15 percent of cases of endogenous Cushing syndrome are caused by non-pituitary tumors that secrete excessive ACTH. The causes of this “ectopic ACTH syndrome” include benign or malignant tumors, most commonly in the chest cavity or abdomen.
