| Abstract |
The spread of COVID-19 infection increased the number of patients who underwent pulmonary resection for lung cancer after COVID-19 infection. It is unclear how previous infection with COVID-19 affects perioperative complications and acute exacerbation of interstitial pneumonia after surgery in patients with interstitial pneumonia. An 80-year-old man was referred to our hospital because of a tumor in his left lung. Chest computed tomography showed a 28-mm nodule in the lower lobe of the left lung and usual interstitial pneumonia in bilateral lungs. Bronchoscopic examination was performed, which diagnosed squamous cell carcinoma. Pulmonary function testing revealed restrictive ventilatory impairment, and we planned to perform basal segmentectomy of the left lung. However, before the planned surgery, the patient contracted symptomatic COVID-19. Chest computed tomography revealed ground-glass opacities owing to COVID-19. The patient was admitted for surgery 7 weeks after COVID-19 infection. Preoperatively, pulmonary function testing was repeated, which revealed decreased % vital capacity (%VC) and % diffusing capacity for carbon monoxide (%DLco). The 6-min walk test indicated a distance of 500 m, and the percutaneous oxygen saturation at the end of the test was 94%. Basal segmentectomy of the left lung was performed by video-assisted thoracoscopic surgery. The patient's postoperative course was favorable, and he was discharged without the need for oxygen inhalational therapy 12 days after the surgery. Pathological examination of the resected specimen revealed usual interstitial pneumonia in the non-cancerous areas of the lung. Additionally, the infiltration of immature fibroblasts in the alveoli and perivascular infiltration of inflammatory cells were observed, which were consistent with fibrotic change after inflammation owing to COVID-19. Three months after the surgery, the patient was alive without recurrence or acute exacerbation of the interstitial pneumonia. Pulmonary function testing 6 weeks after surgery revealed decreased %VC and %DLco. Testing 12 weeks after surgery revealed persistently decreased %VC and improved %DLco (Table 1). Table 1 Pulmonary function test results before and after COVID-19 infection and 6 and 12 weeks after surgery VC (ml) %VC (%) %DLco (%) Before COVID-19 infection 2070 71.9 74.9 7 weeks after COVID-19 infection 1700 59.6 51.9 6 weeks after surgery 1500 52.6 53.1 12 weeks after surgery 1510 53.0 61.7 %VC % vital capacity, %DLco % diffusing capacity for carbon monoxide CONCLUSION: We successfully performed basal segmentectomy of the left lung for lung cancer 7 weeks after COVID-19 infection in a patient with severe interstitial pneumonia and restrictive ventilatory impairment. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 September 2022.
All research outputs
#15,146,027
of 24,489,824 outputs
Outputs from Surgical Case Reports
#67
of 530 outputs
Outputs of similar age
#201,161
of 425,783 outputs
Outputs of similar age from Surgical Case Reports
#3
of 29 outputs
Altmetric has tracked 24,489,824 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 530 research outputs from this source. They receive a mean Attention Score of 1.0. This one has done well, scoring higher than 86% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 425,783 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 50% of its contemporaries.
We're also able to compare this research output to 29 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 93% of its contemporaries.
