SYNPOSIS

Dr. Beall emphasizes the underrecognition and undertreatment of sacral insufficiency fractures, pointing out the high mortality and chronic pain rates associated with non-treatment. He urges providers to consider this diagnosis, especially if the patient is describing symptoms of pain with position changes with standing, sitting, and laying, has pubic rami fractures, or reports a history of pelvic radiation. Even with imaging, the diagnosis can remain elusive, since it is not commonly recognized on x-ray and may not show obvious cortical disruption on CT or MRI.

We also review the current literature on sacroplasty efficacy in lowering patient-reported pain scores and adverse events associated with treatment versus conservative management. Dr. Beall speaks about the importance of real-world data collection in the form of patient registries and the insight that these resulting studies have on applications of sacroplasty in specific patient populations.

SYNPOSIS

It is important to distinguish burnout from moral injury, with the former concept more focused on personal resilience, and the latter defined as extrinsic circumstances that lead to disconnection with one’s career. A key finding from the study was the negative correlation between degree of moral injury and quality of life. Respondents’ free text answers identified a variety of factors contributing to moral injury. The doctors also speak about strategies for addressing moral injury such as psychotherapy, spiritual care, and physical exercise. Most importantly, they believe it is crucial to target systemic factors with efforts to increase physician leadership, administrative support, and research in physician wellness.

Dr. Patrone explains his interest in critical limb ischemia (CLI) and describes how he reached out to colleagues around the world with the intention of drafting a paper that summarizes research in below-the-ankle interventions and increases awareness of the woundosome concept.

He explains the woundosome concept, which aims to understand how each patient’s foot vasculature influences the effectiveness of below-the-ankle interventions and tissue healing. Understanding each patient’s anatomy, having adequate imaging of the foot, obtaining pedal acceleration times, and using micro-oxygen sensors are strategies to assess wound perfusion, which is integral for treatment planning and prognosis. He illustrates these techniques in a case study of a non-healing wound.

Finally, Dr. Patrone shares some technical tips for below-the-ankle interventions, including the benefits of ipsilateral antegrade access, sheath selection, and strategic contrast administration.

SYNPOSIS

The guests start by describing their typical referral patterns, noting that most cases come through the emergency department. In terms of workup, it is important to distinguish between acute and chronic DVTs and classify the thrombosis location as either proximal (femoral vein or higher) or distal. Anticoagulation, usually with direct oral anticoagulants, is always started, with efficacy largely determined by patient compliance.

Regarding endovascular intervention, thrombolysis may be an effective adjunctive treatment if the clot occurred within a two-week timespan, but it carries a bleeding risk and requires ICU monitoring. On the other hand, mechanical thrombectomy is an option for both acute and chronic clots, allows for intervention in patients with high bleeding risk, and does not require post-procedural hospitalization. Both physicians emphasize that interventions should be employed if there are long-term benefits of avoiding post-thrombotic syndrome and pulmonary embolism.

The physicians walk through a typical mechanical thrombectomy procedure, which involves the thrombectomy device, venogram, intravascular ultrasound, and possible stent placement. Finally, they discuss recent data, including the ATTRACT Trial for thrombolytics and the CLOUT Registry and Trial for ClotTriever use. Notably, they mention the DEFIANCE Trial as a current prospective randomized clinical trial for ClotTriever use in the iliofemoral region.
