safety of consecutive bilateral decubitus digital subtraction myelography in patients with spontaneous intracranial hypotension and occult csf leak
American Journal of Neuroradiology, 2020Co-Authors: M C Pope, Carrie M Carr, Waleed Brinjikji, D K KimAbstract:BACKGROUND AND PURPOSE: Digital subtraction myelography performed with the patient in the lateral decubitus position has the potential for increased sensitivity over prone-position myelography in the detection of spinal CSF-venous fistulas, a well-established cause of spontaneous intracranial hypotension. We report on the safety of performing routine, consecutive-day right and left lateral decubitus digital subtraction myelography in these patients. MATERIALS AND METHODS: In this retrospective case series, all patients undergoing consecutive-day lateral decubitus digital subtraction myelography for suspected spinal CSF leak between September 2018 and September 2019 were identified. Chart review was performed to identify any immediate or delayed adverse effects associated with the procedures. Procedural parameters were also analyzed due to inherent variations associated with the positive-pressure myelography technique that was used. RESULTS: A total of 60 patients underwent 68 pairs of consecutive-day lateral decubitus digital subtraction myelographic examinations during the study period. No major adverse effects were recorded. Various minor adverse effects were observed, including pain requiring analgesics (27.2%), nausea/vomiting requiring antiemetics (8.1%), and transient neurologic effects such as syncope, vertigo, altered mental status, and autonomic dysfunction (5.1%). Minor transient neurologic effects were correlated with increasing volumes of intrathecal saline injectate used for thecal sac prepressurization. CONCLUSIONS: In patients with spontaneous intracranial hypotension and suspected spontaneous spinal CSF leak, consecutive-day lateral decubitus digital subtraction myelography demonstrates an acceptable risk profile without evidence of neurotoxic effects from cumulative intrathecal contrast doses. Higher intrathecal saline injectate volumes may correlate with an increased incidence of minor transient periprocedural neurologic effects.

lateral decubitus digital subtraction myelography tips tricks and pitfalls
American Journal of Neuroradiology, 2020Co-Authors: D K Kim, Waleed Brinjikji, Pearse P Morris, Felix E Diehn, Vance T Lehman, Greta B Liebo, Jonathan M Morris, Jared T Verdoorn, Jeremy K Cutsforthgregory, Richard I FarbAbstract:Digital subtraction myelography is a valuable diagnostic technique to detect the exact location of CSF leaks in the spine to facilitate appropriate diagnosis and treatment of spontaneous spinal CSF leaks. Digital subtraction myelography is an excellent diagnostic tool for assessment of various types of CSF leaks, and lateral decubitus digital subtraction myelography is increasingly being used to diagnose CSF-venous fistulas. Lateral decubitus digital subtraction myelography differs from typical CT and fluoroscopy-guided myelograms in many ways, including equipment, supplies, and injection and image-acquisition techniques. Operators should be familiar with techniques, common pitfalls, and artifacts to improve diagnostic yield and prevent nondiagnostic examinations.

intrarenal backflow during retrograde Pyelography with graded intrapelvic pressure a pathoanatomic study
Apmis, 2009Co-Authors: H S Thomsen, Svend LarsenAbstract:Histologic examination was performed in 21 baby-pig kidneys after retrograde Pyelography with a mixture of meglumine sodium diatrizoate and Ferritin at intrapelvic pressures of either 30–35 or 70–75 mm Hg. In further 4 kidneys light microscopy was done after retrograde Pyelography with a mixture of barium sulfate and gelatin at an intrapelvic pressure of 70–75 mm Hg. The primary pathway for intrarenal backflow was canalicular. The contrast material entered the interstitium only by one route: Tubular leakage. Only in the central portions of the kidney leakage was seen. Interstitial Ferritin was found more frequently in areas with intrarenal backflow at an intrapelvic pressure of 70–75 mm Hg than of 30–35 mm Hg.
