Epidural cement leakage (CL) is a common complication in cement-augmented fenestrated pedicle screw fixation (CAFPSF) with the potential for neural injury. However, there are no reports discussing basivertebral vein morphology and pedicle screw placement, which are critical in the analysis of the risk of epidural CL after CAFPSF. ⋯ In osteoporotic patients receiving CAFPSF, epidural CL is relatively common. The morphology of basivertebral foramen should be taken into account when planning a CAFPSF procedure. It is important to try and achieve a deeper screw implantation, especially when a magistral type of basivertebral foramen is present.

Microsurgical Obliteration of Craniocervical Junction Dural Arteriovenous Fistulas: Multicenter Experience.
Dural arteriovenous fistulas (dAVFs) located at craniocervical junction are extremely rare (1%-2% of intracranial/spinal dAVFs). Their angio-architectural complexity renders endovascular embolization to be challenging given multiple small feeders with risk of embolysate reflux into vertebral artery and limited transvenous access. The available literature discussing microsurgery for these lesions is limited to few case reports. ⋯ Craniocervical dAVFs represent rare entity of lesions presenting most commonly with hemorrhage or myelopathy because of venous congestion. Microsurgery using a far lateral approach provides robust exposure and visualization for these lesions and allows obliteration of the arterialized draining vein intradurally as close as possible to the fistula point. This approach was associated with a high rate of angiographic cure and favorable clinical outcomes.

Multicenter Study Observational StudyLong-term risk of venous thromboembolism recurrence after isolated superficial vein thrombosis.
Essentials Long-term risk of recurrence of isolated superficial vein thrombosis (SVT) is under-studied. We analyzed data from a cohort of first SVT and proximal deep vein thrombosis (DVT) without cancer. The risk of recurrence as DVT or pulmonary embolism is twice lower in SVT patients. ⋯ Saphenian junction involvement by iSVT was not associated with a higher risk of recurrence (5.2% per PY versus 5.4% per PY), but was associated with recurrence exclusively as deep-VTE events. Conclusion In patients with a first iSVT without cancer, after stopping anticoagulants, the incidence of deep-VTE recurrence is half that of DVT patients, but the overall risk of recurrence is similar. Ssaphenian junction involvement seems to influence the risk of deep-VTE recurrence, whereas varicose vein status has no impact or a low impact on VTE recurrence.

Randomized Controlled Trial Multicenter StudyAnticoagulant therapy for symptomatic calf deep vein thrombosis (CACTUS): a randomised, double-blind, placebo-controlled trial.
The efficacy and safety of anticoagulant treatment is not established for patients with acute symptomatic deep vein thrombosis (DVT) of the calf. We aimed to assess whether therapeutic anticoagulation is superior to placebo in patients with symptomatic calf DVT. ⋯ Swiss National Science Foundation, the Programme Hospitalier de Recherche Clinique in France, and the Canadian Institutes of Health Research.

Randomized Controlled Trial Multicenter Study
One versus two years of elastic compression stockings for prevention of post-thrombotic syndrome (OCTAVIA study): randomised controlled trial.
To study whether stopping elastic compression stockings (ECS) after 12 months is non-inferior to continuing them for 24 months after proximal deep venous thrombosis. ⋯ Stopping ECS after one year in compliant patients with proximal deep venous thrombosis seemed not to be non-inferior to continuing ECS therapy for two years in this non-inferiority trial.
