ABSTRACT
Background@#The emergence of the severe acute respiratory syndrome coronavirus 2 omicron variant has been triggering the new wave of coronavirus disease 2019 (COVID-19) globally. However, the risk factors and outcomes for radiological abnormalities in the early convalescent stage (1 month after diagnosis) of omicron infected patients are still unknown. @*Methods@#Patients were retrospectively enrolled if they were admitted to the hospital due to COVID-19. The chest computed tomography (CT) images and clinical data obtained at baseline (at the time of the first CT image that showed abnormalities after diagnosis) and 1 month after diagnosis were longitudinally analyzed. Uni-/multi-variable logistic regression tests were performed to explore independent risk factors for radiological abnormalities at baseline and residual pulmonary abnormalities after 1 month. @*Results@#We assessed 316 COVID-19 patients, including 47% with radiological abnormalities at baseline and 23% with residual pulmonary abnormalities at 1-month follow-up. In a multivariate regression analysis, age ≥ 50 years, body mass index ≥ 23.87, days after vaccination ≥ 81 days, lymphocyte count ≤ 1.21 × 10 -9 /L, interleukin-6 (IL-6) ≥ 10.05 pg/mL and IgG ≤ 14.140 S/CO were independent risk factors for CT abnormalities at baseline. The age ≥ 47 years, presence of interlobular septal thickening and IL-6 ≥ 5.85 pg/mL were the independent risk factors for residual pulmonary abnormalities at 1-month follow-up. For residual abnormalities group, the patients with less consolidations and more parenchymal bands at baseline could progress on CT score after 1 month. There were no significant changes in the number of involved lung lobes and total CT score during the early convalescent stage. @*Conclusion@#The higher IL-6 level was a common independent risk factor for CT abnormalities at baseline and residual pulmonary abnormalities at 1-month follow-up. There were no obvious radiographic changes during the early convalescent stage in patients with residual pulmonary abnormalities.
ABSTRACT
Objective:To investigate the imaging characteristics of chest CT angiography in patients with active pulmonary tuberculosis complicated with pulmonary embolism, so as to improve the detection rate of active pulmonary tuberculosis complicated with pulmonary embolism.Methods:The clinical data of 103 patients with active pulmonary tuberculosis treated in Tianjin Haihe Hospital from January 2013 to January 2020 were retrospectively analyzed, including general conditions, symptoms and complications. According to the occurrence of pulmonary embolism, the patients were divided into active pulmonary tuberculosis complicated with pulmonary embolism group (study group, n=43) and active pulmonary tuberculosis without pulmonary embolism group (control group, n=60). The time between the onset of pulmonary embolism and the onset of tuberculosis of the patients in the study group was collected. The chest CT imaging characteristics of the patients of two groups were analyzed. The imaging characteristics, embolism distribution and secondary changes of the patients in the study group were summarized. Results:Time from onset of tuberculosis to pulmonary embolism of the patients in the study group was about 60 days (14 days to 75 days). The incidence of chest tightness and dyspnea of the patients in the study group was significantly higher than that in the control group (all P<0.05). The number of lung lobes involved in lung lesions of the patients in the study group was significantly higher than that in the control group ( P<0.05). The incidence of lesions in the middle lobe of the right lung, the tongue lobe of the left lung and the lower lobes of both lungs of the patients in the study group was higher than that in the control group (all P<0.05). The incidence of peripheral pulmonary embolism was significantly higher than that of central pulmonary embolism ( P<0.05). However, the incidence of atelectasis, pulmonary artery widening, and right heart enlargement in the patients with central pulmonary embolism was significantly higher than that in the patients with central pulmonary embolism (all P<0.05). Conclusions:Multi-slice spiral CT chest angiography can show some important imaging manifestations of patients with active pulmonary tuberculosis and pulmonary embolism, which is helpful for the early detection of the disease and the improvement of its prognosis. Multi slice spiral CT chest angiography can show some important imaging manifestations of patients with active pulmonary tuberculosis complicated with pulmonary embolism, and timely detection is helpful to improve the prognosis of patients with active pulmonary tuberculosis complicated with pulmonary embolism.
ABSTRACT
Objective To analyse the quality of life in patients with severe acute respiratory syndrome (SARS) for 10 years. Methods Twenty-five SARS patients were collected as SARS group and 25 healthy persons were used as control group. There were no significant differences in general clinical data between two groups. The quality of life of the respondents was evaluated by the MOS item short form health survey (SF-36) including physiological function, physical pain, general health condition, energy, social function, emotional function and mental health. The pulmonary function indicators including forced vital capacity (FVC), one second forced expiratory volume (FEV1), one second rate (FEV1/FVC), total lung capacity (TLC), residual volume (RV), corrected breath diffusing capacity (TLCOc SB) and corrected dispersion rate TLCOc/VA were also compared between two groups. The correlation between each dimension score of pulmonary function indexes and quality of life were analyzed in SARS group. Data of hip and femoral head necrosis were detected by MRI scan in SARS group of patients. Results Total quality of life score was poor in 23 cases (92.0%), and moderate quality of life score in 2 cases (8.0%). The quality of life score was lower in SARS group than that of control group (P<0.01). Data of TLCOc SB was lower in SARS group than that of control group. The score of physiological function was positively correlated with FEV1 and FEV1/FVC. The score of physical pain was positively correlated with FEV1/FVC (P<0.05). There were no significant differences between quality of life score and pulmonary function indicators. There were 11 cases (44%) of avascular necrosis of femoral head, and 14 cases (56%) of non-avascular necrosis of femoral head in SARS group. The score of physiological function was lower in femoral head necrosis group than that of non necrosis group (P<0.05). ConclusionThe lower quality of life in patients with SARS is not only related with psychological factors but also related with physical factors. The damage of pulmonary function and (or) necrosis of femoral head affect the quality of life in patients with SARS, especially the physiological function.
ABSTRACT
<p><b>BACKGROUND</b>Hemoptysis is a significant clinical entity with high morbidity and potential mortality. Both medical management (in terms of resuscitation and bronchoscopic interventions) and surgery have severe limitations in these patients population. Bronchial artery embolization (BAE) represents the first-line treatment for hemoptysis. This article discusses clinical analysis, embolization approach, outcomes and complications of BAE for the treatment of hemoptysis.</p><p><b>METHODS</b>A retrospective analysis of 344 cases, who underwent bronchial arteriography at Tianjin Haihe Hospital between 2006 and 2013. Several aspects of outcome were analyzed: Demographics, clinical presentation, radiographic studies, results, complications and follow-up of BAE.</p><p><b>RESULTS</b>Three hundred and forty-four consecutive patients underwent bronchial arteriography, 336 of 344 patients (97.7%) performed BAE; there were 1530 coils for 920 arteries embolized; the main responsible sources for bleeding were right bronchial artery (29.7%), left bronchial artery (21.6%), combined right and left bronchial trunk (18.4%), right intercostal arteries (13.3%); 61 patients (17.7%) had recurrent hemoptysis within 1 month after undergoing BAE, 74 patients (21.5%) had recurrent hemoptysis over 1 month after undergoing BAE; The common complications of BAE included subintimal dissection, arterial perforation by a guide wire, fever, chest pain, dyspnea, etc. The follow-up was completed in 248 patients, 28 patients had been dead, 21 patients still bleed, 92 patients had lost to follow-up.</p><p><b>CONCLUSIONS</b>The technique of BAE is a relatively safe and effective method for controlling hemoptysis . The complications of BAE are rare. Although the long-term outcome in some patients is not good, BAE may be the only life-saving treatment option in patients who are poor surgical candidates.</p>

Objective:To explore the clinical value of chest multi-slice computed tomography angiography (MSCTA) as a preoper-ative examination for lung cancer patients undergoing pulmonary lobectomy. Methods: Sixty lung cancer patients formed the study population and were randomly divided into 2 groups of 30 cases each. In the experimental group, CTA images of the tumors and pulmo-nary artery, bronchial artery, pulmonary vein were acquired, analyzed, and post-processed using VR to determine the anatomical rela-tionship between vessels and tumors. Pulmonary lobectomy followed. Cases in the control group underwent pulmonary lobectomy with-out guidance by chest MSCTA. Operation times and amounts of operative blood loss were compared between the two groups. Results:Significant differences between groups in terms of operation time (study group vs. control group, 199±55.7 vs. 231.5±51.2(min);P=0.02) and amount of operative blood loss (study group vs. control group, 318.33±99.6 vs. 431.7±89.5(mL), P<0.01) were observed. Val-ues of operation time and amount of contrast agents in the study group were consistently lower than those in the control group. Conclu-sion:Chest MSCTA can shorten the operation time and reduce the amount of operative blood loss during pulmonary lobectomy. Thus, the technique has significant clinical value.
