A 72-year-old man with end-stage renal disease (ESRD) undergoing transurethral resection of a bladder tumor experienced severe and prolonged hypotension after receiving oral 5-aminolevulinic acid (5-ALA). Continuous infusions of norepinephrine and vasopressin ultimately resolved the hypotension over the course of 26 hours. It is uncertain whether 5-ALA is causative or is a contributing factor that influences other factors, such as hypovolemia after hemodialysis and autonomic nerve dysfunction associated with ESRD. Our findings suggest that anesthesiologists should be aware of the possible occurrence of hypotension after administration of 5-ALA, and urologists should consider intravesical 5-ALA administration in patients with ESRD.

Spontaneous intracranial hypotension (SIH) has been increasingly characterized in recent years. A definitive diagnostic algorithm remains controversial because several symptoms are often found to be nonspecific. ⋯ Our case shows how greater occipital nerve block (GONB) can expedite SIH diagnosis in a man with atypical presentation by reducing the sensory input from the posterior cranial fossa. The relief provided by GONB allowed to diagnose SIH promptly and the patient underwent a curative EBP.

A 78-year-old woman complained of numbness, tingling, and pain in the left leg 6 months after greater saphenous vein stripping. Ultrasonography identified a mass adjacent to the saphenous nerve at the scar. Ultrasound-guided hydrodissection separated the mass from the nerve. ⋯ The visual analog pain scale decreased from 80 (before treatment) to 60 three days later. The hydrodissection was repeated weekly for a total of 8 times, and the pain completely resolved 4 months later. Ultrasound-guided hydrodissection is effective to treat nerve entrapment after lower extremity varicose vein stripping.
