    World Neurosurg, 2020 10;142:167-170.

    BACKGROUND: Intracranial vascular malformations are increasingly being treated via the endovascular route. Though generally safe, a multitude of intraprocedural complications that potentially lead to disastrous clinical outcomes may arise. It is crucial for the operators to be well versed with the various techniques that are available to overcome any procedure-specific complications.

    METHODS: We present 2 cases in which we encountered premature intravascular detachment of the microcatheter tip and coil migration while treating a dural arteriovenous fistula and aneurysm, respectively. We used a stentriever to remove the detached microcatheter tip and suction using the reperfusion catheter to remove the migrated coil, both techniques that have not been reported in the literature thus far.

    RESULTS: Detached microcatheter tip and migrated coil were successfully retrieved using a stentriever and aspiration catheter.

    CONCLUSIONS: These novel techniques could potentially reduce mortality and morbidity associated with neurointervention.

    Low back pain (LBP) is a common disorder affecting an increasing number of people worldwide, whose diagnosis is focused on the identification of triggering causes. First line therapy usually starts from conservative approaches, whereas second line treatments include a spectrum of minimally invasive techniques, before resorting to more invasive surgical approaches. Among minimally invasive techniques, percutaneous oxygen-ozone injections represent one of the most common and cost-effective procedures. Aim of this study is to provide a metanalysis on literature evidences on percutaneous oxygen-ozone injections, comparing image-guided to non-image-guided techniques for LBP treatment. Imaging-guided procedures showed better performances compared to non-image-guided techniques based only on anatomical landmarks, with higher therapeutic efficacy and lower age-related variability in clinical results.
