Spontaneous intracranial hypotension (SIH) is a rare disorder that occurs secondary to acquired cerebrospinal fluid (CSF) leaks in the spine. Treatment involves either an epidural blood patch or surgical ligation. Essential to the selecting the optimal management strategy is classifying the type of leak and accurate localization of its level. Hitherto, this has been achieved using conventional imaging methods such as static CT or MR myelography which are adequate for the demonstration of only high flow leaks. Digital subtraction myelography (DSM) is a novel technique which provides superior temporal and spatial resolution in the localization of more challenging slow flow leaks. However, DSM may also be initially non-diagnostic. We report a case of SIH in which repeat DSM revealed a type 3 CSF-venous fistula and demonstrate a possible mechanism of transient CSF leak block resulting in the initial false negative findings based on morphological changes in the culprit nerve sheath diverticulum-pseudomeningocoele complex. The patient underwent successful surgical ligation with clinicoradiological resolution of SIH.

Cerebrospinal fluid–venous fistula is an increasingly recognized cause of spontaneous intracranial hypotension.1 The site of the leak is between the dural sleeve around a spinal nerve root and the surrounding foraminal veins. In appropriately investigated patients, transvenous embolization of the draining foraminal and paraspinal veins has been shown to be an effective way of treating the disease, with low periprocedural morbidity, improvement in symptoms and radiological appearances.2 Video 1 shows the technique employed in a typical case using Onyx (Medtronic, Minnesota, USA) to embolize a CSF–venous fistula at the right T10 neural foramen.Video 1

Spontaneous CSF–venous fistulas may be present in up to one-fourth of patients with spontaneous intracranial hypotension. This is a recently discovered type of CSF leak, and much remains unknown about these fistulas. Spinal CSF–venous fistulas are usually seen in coexistence with a spinal meningeal diverticulum, suggesting the presence of an underlying structural dural weakness at the proximal portion of the fistula. The authors now report the presence of soft-tissue venous/venolymphatic malformations associated with spontaneous spinal CSF–venous fistulas in 2 patients with spontaneous intracranial hypotension, suggesting a role for distal venous pathology. In a third patient with spontaneous intracranial hypotension and a venolymphatic malformation, such a CSF–venous fistula is strongly suspected.

Punch grafting is an alternative treatment to enhance wound healing which has been associated with promising clinical outcomes in various leg and foot wound types. We aimed to evaluate the clinical outcomes of punch grafting as a treatment for hard-to-heal diabetic foot ulcers (DFUs). Six patients with chronic neuropathic or neuroischemic DFUs with more than 6 months of evolution not responding to conventional treatment were included in a prospective case series between May 2017 and December 2020. All patients were previously debrided using an ultrasound-assisted wound debridement and then, grafted with 4 to 6 mm punch from the donor site that was in all cases the anterolateral aspect of the thigh. All patients were followed up weekly until wound healing. Four (66.7%) DFUs were located in the heel, 1 (16.7%) in the dorsal aspect of the foot and 1 (16.7%) in the Achilles tendon. The median evolution time was 172 (interquartile range [IQR], 25th-75th; 44-276) weeks with a median area of 5.9 (IQR; 1.87-37.12) cm2 before grafting. Complete epithelization was achieved in 3 (50%) patients at 12 weeks follow-up period with a mean time of 5.67 ± 2.88 weeks. Two of the remaining patients achieved wound healing at 32 and 24 weeks, respectively, and 1 patient showed punch graft unsuccessful in adhering. The median time of wound healing of all patients included in the study was 9.00 (IQR; 4.00-28.00) weeks. The wound area reduction (WAR) at 4 weeks was 38.66% and WAR at 12 weeks was 88.56%. No adverse effects related to the ulcer were registered through the follow-up period. Autologous punch graft is an easy procedure that promotes healing, achieving wound closure in chronic DFUs representing an alternative of treatment for hard-to-heal DFUs in which conservative treatment has been unsuccessful.

Purpose: Evaluate the clinical outcomes of the secondary piggyback add-on IOL implantation in the ciliary sulcus for pseudophakic patients previously implanted with a monofocal IOL, who pursue a spectacle-free option after IOL surgery. Methods: A prospective case series including seven pseudophakic patients who underwent an in-the-bag monofocal IOL implantation. All eyes underwent a piggyback IOL implantation of the new sulcus designed A4 AddOn IOL in the ciliary sulcus as a secondary procedure for pseudophakic patients pursuing a spectacle-free option for near and intermediate distance after IOL surgery. Results: Seven eyes from six patients were included in this study, from which 4 (71.43%) were female, with a mean age of 58.33 ± 3.5 years (range 54–63; 95% CI 54.66, 62.01). The postoperative spherical equivalent at the 3-month visit was −0.10 m ± 0.82. Also, the UDVA was 0.11 ± 0.08 logMAR, the UIVA 0.01 ± 0.03, and the UNVA 0.01 ± 0.03 3 months after their surgical procedure. Conclusions: The A4 AddOn multifocal IOL’s secondary piggyback implant is an efficient alternative for monofocal pseudophakic patients seeking presbyopia solutions. This sulcus-designed IOL provides an optimal visual outcome for near and distance vision.
