We report a case of deep femoral artery (DFA) retrograde access for recanalization of an accidental ostial occlusion complicating an antegrade-retrograde superficial femoral artery (SFA) procedure. A 77-year-old man with chronic limb-threatening ischemia of the right lower limb was submitted to a duplex ultrasound that showed a heavy calcified SFA chronic total occlusion. During antegrade and retrograde attempts to cross the SFA obstruction, a control angiogram unexpectedly showed the ostial occlusion of the DFA. Several antegrade attempts to cross the DFA occlusion with various guidewires and catheters were unsuccessfully made. Retrograde access was achieved by direct puncture of the DFA distally to the first perforating artery. With sheathless approach, the occlusion was crossed, the retrograde guidewire was externalized through the femoral sheath, and the balloon angioplasty was then performed antegradely. The SFA recanalization was interrupted because of patient discomfort. The patient had an uncomplicated recovery, with immediate resolution of rest pain probably because of the resolution of the underestimated DFA stenosis. The retrograde DFA access is a useful bailout technique in case of accidental ostial occlusion of the DFA.

Introduction: Soft-tissue sarcomas arising in the thigh may require total or subtotal compartmentectomy, with subsequent need for functional reconstruction with free functional muscle transfer (FFMT). We present our series, describing a new approach with chimeric propeller antero-lateral thigh-vastus lateralis (ALT-VL) free flap, which allows for independent muscle inset and soft tissue defect resurfacing.
Patient And Methods: A retrospective review of a prospectively maintained database was performed, analyzing all patients referred to Fondazione Policlinico Universitario Campus Bio-Medico, Rome, Italy, between 2018 and 2023 for soft-tissue sarcomas of the thigh requiring wide excision and reconstruction with functional ALT-VL.
A case of emergency stent graft placement for subclavian artery injury during ventriculoperitoneal shunt placement.

With advancements in medical devices and imaging techniques, endovascular treatment using stent grafts has emerged as a viable and aggressive therapeutic option for traumatic subclavian artery injuries, including iatrogenic cases. Existing literature suggests that endovascular treatment is less invasive and offers hemostatic success rates comparable to traditional surgical methods. However, there is a paucity of case reports, necessitating further investigation into treatment indications and procedural challenges.

Cardiovascular imaging with camera-on-tip endoscopes has the potential to provide physiologically relevant data on the tissue state and device placement that can improve clinical outcomes. In this work, we review the unmet clinical need for image-based cardiovascular diagnostics and guidance for minimally invasive procedures. We present a 7 Fr camera-on-tip endoscope with fibre-coupled multispectral illumination that includes methods for imaging in a blood-filled field of view (FOV).

Objective: Globally, one in four pregnant women is classified as overweight or obese, based on their prepregnancy body mass index (BMI). Obese pregnant women are at increased risk of adverse pregnancy outcomes and long-term cardiovascular disease that occurs earlier in life. This study aimed to assess maternal hemodynamic and vascular parameters at 35-37 weeks' gestation, to understand the alterations that may occur in association with increased maternal BMI and gestational weight gain, and to evaluate obesity-related pregnancy outcomes.

Background: Transcatheter aortic valve replacement (TAVR) harbors the risk of periprocedural complications that require emergent cardiac surgery, or "surgical bailout." Surgical bailout intends to be lifesaving but is associated with high mortality. This has given rise to discussion on the necessity of surgical backup during TAVR.
