Microsurgical removal of a misplaced intraspinal venous stent in a patient with inferior vena cava atresia.

Microsurgical removal of a misplaced intraspinal venous stent in a patient with inferior vena cava atresia. J Neurosurg Spine. 2020 Jan 17;:1-5 Authors: Schwartz C, Hafez A, Lönnrot K, Rezai Jahromi B, Lappalainen K, Lehecka M, Siironen J, Niemelä M Abstract Inferior vena cava atresia (IVCA) is a rare vascular condition that may be treated by venous stenting. The authors report on the microsurgical removal of an intraspinally misplaced stent causing nerve root compression and neurological deficits.A 42-year-old patient with IVCA and painful cutaneous collaterals had been scheduled for treatment by stenting of the iliocaval confluence and associated venous collaterals. Initial stenting of the right iliac vein was successful; however, during recanalization of the left paravertebral plexus, the stent entered the spinal canal via extraspinal-to-intraspinal venous collaterals. Because of the use of monoplanar angiography, the stent misplacement was not seen during the procedure. Postinterventionally, the patient experienced a foot elevation weakness (grade 1/5) as well as pain and hypesthesia corresponding to the L5 dermatome. Ultrasonography ruled out a lumbosacral plexus hematoma. CT angiography showed that a stent had entered the spinal canal through the left S1 neuroforamen causing nerve root compression. The intraspinal portion of the stent was removed piecemeal via a left-sided hemilaminectomy. Venous bleeding due to the patient's anticoagulat...

We present a surgical technique that diminishes tension of the repair with MCPJ flexion. Twenty-two EDC tendon stabilization procedures were performed between 2006 and 2017 using a tendon flap method. The selection criteria for this group of patients included completely dislocating extensor tendons with persistent complaints of pain and decrease in finger extension despite at least a 6-week conservative treatment attempt. All subjects underwent surgical treatment for tendon centralization using a distally based tendinous flap from the EDC sutured to the adjacent finger volar plate. A mathematical model was developed to ana...

Radiocapitellar arthrosis represents a serious sequela of pediatric elbow injuries. Although persistent pain and disability are not uncommon in such cases, treatment remains controversial. The present study aimed to review the clinical outcomes after a new surgical treatment with partial radial head resection and corium interposition arthroplasty. To date, 3 adolescent cases underwent the surgical procedure and postoperative care. Thorough clinical and radiographic follow-up was performed. The mean age at the time of surgery was 14.4 years (range, 13 to 16 y) and mean duration of follow-up was 19 months (range, 12 t...

We present a case report of an adult woman with AKL-positive ALCL, diagnosed by endobronchial ultrasound-guided transbronchial needle aspirate (EBUS-TBNA).A 59-year-old women with no history of breast implants, was admitted for a four-month low back pain. Initially, the patient was treated for a spondyloarthropathy, but due to persistence of the symptoms, a lumbosacral MRI was performed, showing changes in morphology and signal intensity in the vertebral body of L3, along with edema and a paravertebral collection that affected the left psoas muscle, suggesting granulomatous spondylodiscitis. Chest CT-scan showed mild left ...

Although the papers I have written with residents and faculty are not always accepted, most reviewers begin their comments with “This is a clearly written paper.” I think this must be why several people have asked me if I have a formula for writing research papers. The answer is yes, I do, so I decided to write this brief essay to describe it. I do this because I have learned the hard way that good data can be sunk by ba d writing and have seen the pain in some colleagues’ faces when they have a good project but can only stare at a blank computer screen, not knowing how to start.

A 58-year-old female presents with a 1-year history of hematochezia, 20-pound weight loss, and increased straining with bowel movements. She denies increased bowel frequency or change in stool caliber. Her medical history is notable for irritable bowel syndrome, but otherwise unremarkable. She has no family history of malignancy and does not take any prescribed medications or supplements. She denies abdominal pain, bone pain, or any symptoms concerning for metastatic disease. Her initial physical examination was notable for an Eastern Cooperative Oncology Group performance status of 0, and presence on digital rectal examin...

Conclusions: Intraoperative liposomal bupivacaine use reduced opioid use and postoperative pain for the first 24 hours after fixation of intertrochanteric femur fractures. Significant increases in likelihood of discharge to home may present an opportunity for cost savings. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

CONCLUSION About one third of the injuries previously classified as grade III will be upgraded to grade IV using the 2018 AAST, which adds to the heterogeneity of grade IV injuries. Although the 2018 AAST grading provides more anatomic details on injury patterns and includes important radiologic findings, it did not outperform the 1989 AAST grading in predicting bleeding interventions. LEVEL OF EVIDENCE Prognostic and Epidemiological Study, level III.

INTRODUCTION Admission computed tomography (CT) is a widely used diagnostic tool for patients with pelvic fractures. In this pilot study, we hypothesized that pelvic hematoma volumes derived using a rapid automated deep learning-based quantitative visualization and measurement algorithm predict interventions and outcomes including (a) need for angioembolization (AE), pelvic packing (PP), or massive transfusion (MT), and (b) in-hospital mortality. METHODS We performed a single-institution retrospective analysis of 253 patients with bleeding pelvic fractures who underwent admission abdominopelvic trauma CT between 2008 ...

Conclusion: Capillary nonperfusion area in the posterior retina increases with increasing DR severity as measured by swept-source OCTA. Quantitative analysis of retinal nonperfusion on wide-field OCTA may be useful for early detection and monitoring of disease in patients with diabetes and DR.
