AI Article Synopsis

  • The study investigates a new, minimally invasive technique for releasing the plantaris tendon (PT) using ultrasound guidance, which could improve treatment for Achilles region pain without traditional surgery.
  • Conducted on 20 unembalmed cadaveric specimens, the procedure was completed successfully with a small incision and without causing damage to surrounding tissues.
  • The results indicate that this technique is safe and effective, suggesting further research is needed to explore its clinical applications.

Article Abstract

Background: The plantaris tendon (PT) has been implicated in the pathogenesis of symptoms in a subset of patients with Achilles region pain syndromes and traditionally has been managed via open surgical resection. Although the PT can be visualized on ultrasound, a minimally invasive technique for sonographically guided PT release has not been formally described.

Objective: To validate a technique to perform sonographically guided PT release in an unembalmed cadaveric model.

Design: Prospective, cadaveric laboratory investigation.

Setting: Procedural skills laboratory in a tertiary medical center.

Subjects: Twenty unembalmed cadaveric knee-ankle-foot specimens (10 right, 10 left) obtained from 16 donors (6 male, 10 female) ages 55-96 years (mean 82.6 years) with body mass indexes of 14.1-33.2 kg/m (mean 23.3 kg/m ).

Methods: After simulated local anesthesia and sonographically guided hydrodissection of the plantaris tendon-Achilles tendon interval, a single experienced operator performed sonographically guided PT release on each specimen using an in-plane, lateral-to-medial approach, a commercially available, disposable 3.0-mm hook knife, and either a 17-5 MHz or 15-7 MHz linear array transducer. Each specimen was subsequently dissected to assess for PT release and iatrogenic injury.

Main Outcome: Status of the PT, Achilles tendon, and regional neurovascular structures as determined by dissection.

Results: All 20 PT releases were completed in a single attempt through a 3- to 5-mm incision. Dissection confirmed complete PT release in all specimens without damage to the adjacent Achilles tendon or regional neurovascular structures.

Conclusion: Sonographically guided PT release is technically feasible and can be performed while avoiding injury to the Achilles tendon and regional neurovascular structures. Additional research is warranted to further define the role of sonographically guided PT release in patients with suspected PT-mediated Achilles region pain syndromes.

Level Of Evidence: IV.

This study aimed to evaluate our center's experience in diagnosing and managing placenta accreta spectrum (PAS) in a high-risk population, focusing on prenatal ultrasound features associated with PAS severity and maternal outcomes. We conducted a retrospective analysis of 102 high-risk patients with confirmed placenta previa who delivered at our center between 2018 and 2023. Patients underwent transabdominal and transvaginal ultrasound scans, assessing typical sonographic features.

Background: Adenomyosis is a common benign gynecological disease. Patients often experience abnormal uterine bleeding, dysmenorrhea, and infertility. Percutaneous microwave ablation (PMWA) is a minimally invasive method used for treating adenomyosis while preserving the uterus.

Background: Treatment of symptomatic varicose veins has changed dramatically in the last few years with guidelines now recommending endovenous surgery as first-line intervention. Previously, this was achieved by laser or radiofrequency ablation of the target vein, requiring infiltration of tumescent anesthesia to reduce the risks of thermal damage to surrounding tissue. Endovenous cyanoacrylate injection (VenaSeal™) is a nonthermal, nontumescent endovenous closure technique, increasing patient comfort and is readily performed under local anesthesia only and thus is a feasible technique for in-room treatment.

Article Synopsis
  • Inadvertent intraneural injections during peripheral nerve blocks are common, and this study compares two detection methods: injection pressure monitoring and ultrasound imaging.
  • The research involved anesthesiologists conducting intraneural injections on fresh cadaver arms, measuring both pressure and sonographic images to evaluate outcomes.
  • Results showed that pressure monitoring detected intraneural injection much earlier than ultrasound (after just 0.2 mL vs. 1.2 mL for swelling), confirming that pressure monitoring is a more sensitive technique.

Ultrasound-Guided Thyroid Biopsy.

Thyroid nodules are prevalent, estimated to affect up to 68% of the population, and the incidence increases with age. With the advances in medical imaging utilization, the detection of incidental thyroid nodules continues to rise, and given the low rate of malignancy in incidentally discovered thyroid nodules (4-15%), diagnostic guidelines are imperative for their management. Several guidelines have been developed: the most commonly used guidelines in the United States include the American Thyroid Association (ATA) Guidelines and the American College of Radiology Thyroid Imaging Reporting Data System (TI-RADS).
