Background: Intermediate-high risk pulmonary embolism (PE) carries a significant risk of hemodynamic deterioration or death. Treatment should balance efficacy in reducing clot burden with the risk of complications, particularly bleeding. Previous studies on high-dose, short-term thrombolysis with alteplase (rtPA) showed a reduced risk of hemodynamic deterioration but no change in mortality and increased bleeding complications.

Rationale And Objectives: To evaluate and compare image quality of different energy levels of virtual monochromatic images (VMIs) using standard versus strong deep learning spectral reconstruction (DLSR) on dual-energy CT pulmonary angiogram (DECT-PA).

Materials And Methods: A retrospective study was performed on 70 patients who underwent DECT-PA (15 PE present; 55 PE absent) scans. VMIs were reconstructed at different energy levels ranging from 35 to 200 keV using standard and strong levels with deep learning spectral reconstruction.

Risk factors for venous thromboembolism in patients undergoing neoadjuvant chemotherapy as treatment for ovarian cancer.

Eur J Obstet Gynecol Reprod Biol

December 2024

Department of Gynaecological Oncology, West Kent Cancer Centre, Maidstone and Tunbridge Wells NHS Trust, Hermitage Lane, Maidstone, Kent ME16 9QQ, United Kingdom.

Objective: During the treatment of ovarian cancer, the risk of venous thromboembolism (VTE) post operatively is well established, however, patients may be at even greater risk during neoadjuvant chemotherapy (NACT). This study aimed to determine the incidence and timing of VTE amongst patients undergoing NACT, whether there was an association with survival, and examine risk factors associated with the development of VTE.

Study Design: This was a retrospective cohort study of patients diagnosed with ovarian, fallopian tube and primary peritoneal cancer receiving neoadjuvant chemotherapy betweenApril 2011 and April 2022 at a gynaecological cancer centre in England.

Background: Half of people post pulmonary embolism (PE) experience ongoing symptoms such as dyspnoea, anxiety and depression, exercise limitation and fatigue. These symptoms can reduce their quality of life (QoL), psychological wellbeing, and functional capacity. The efficacy of rehabilitation interventions to prevent and manage these symptoms has not been established.
