Background. Thoracic endometriosis is thought to be the most common form of endometriosis occurring outside of the pelvis. We aimed to characterize thoracic symptoms of endometriosis in a population of patients not necessarily suffering from catamenial pneumothorax, which is most commonly identified as a symptom of thoracic endometriosis. Material and methods. We used a web-based survey addressed to users of two Polish endometriosis patient advocate organizations. The factor that qualified patients for the study was the presence of symptoms in the chest related to the menstrual cycle. Results. A total of 92 respondents were questioned. In this group, 96% (88/92) of patients were previously diagnosed with pelvic endometriosis, 20% (18/92) with thoracic endometriosis, and 18% (17/92) with diaphragmatic endometriosis. The percentage of patients diagnosed with both thoracic and diaphragmatic endometriosis was 15% (14/92). Ninety-eight percent of patients suffered from pain. The four most common symptoms reported by patients were chest pain, dyspnea, cough, and stunned limb, occurring in 96%, 67%, 52%, and 33%, respectively. The feeling of a stunned, weakened limb occurs in older women at 38.4 vs. 35.5 years of age (p = 0.021). There is a trend that women who suffer pain (36.7 vs. 31.3 years of age p = 0.053) and hemoptysis (41.0 vs. 36.2 years of age p = 0.059) are older than women without these symptoms. We identified two unique symptoms of thoracic endometriosis—pouring liquid sensation (13%) and popping sensation (12%)—which can be related to a small amount of gas and fluid in the pleural cavity. Conclusions. Patients who have endometriosis suffer from a constellation of thoracic symptoms related to menses.

Background: Chronic limb-threatening ischemia (CLTI) is associated with high morbidity and substantial healthcare utilization. Length of hospital stay (LOS) after lower limb revascularization is influenced by procedural complexity, but patient physiological reserve may also play a role. We evaluated whether CT-derived lean psoas muscle area (LPMA) is independently associated with LOS in patients undergoing revascularization for CLTI. Methods: We retrospectively analyzed 234 consecutive patients treated with endovascular, hybrid, or open revascularization for CLTI (Rutherford 4–5) between 2018 and 2021. Sarcopenia markers were derived from preoperative CT at the L3 level, including psoas muscle area (PMA), muscle density (PMD), and LPMA. Multivariable linear regression models with log-transformed LOS were used to estimate relative effects on hospitalization duration. Results: Median age was 68 years and 65.4% were male; 76.5% of admissions were urgent. Median LOS was 6 days (IQR 4–9). Procedure type was the strongest determinant of LOS: hybrid (β = 0.69, p < 0.001) and open surgery (β = 0.73, p < 0.001) were associated with approximately 99% and 108% longer LOS compared with endovascular treatment. Higher LPMA was independently associated with shorter LOS (β = −0.00049, p = 0.004). Smoking (β = −0.21, p = 0.003) and history of myocardial infarction (β = −0.19, p = 0.030) were associated with shorter LOS, whereas dialysis showed a non-significant trend toward longer hospitalization (β = 0.36, p = 0.056). Conclusions: In patients undergoing lower limb revascularization for CLTI, CT-derived LPMA demonstrated a modest but independent association with hospital stay duration after adjustment for procedural and clinical factors. Given the exploratory nature of this study, these hypothesis-generating findings support further evaluation of imaging-based muscle assessment as an adjunct marker of physiological reserve in this high-risk population.
