Completion Pneumonectomy

Abstract It has been previously suggested that lung tissue remains viable without blood supply from the pulmonary artery (PA). However, our experience demonstrates otherwise. We present 2 cases of accidental left lower lobe PA occlusion during upper lobectomy causing ischaemic changes to the remaining lung tissue. Both patients became septic secondary to necrosis of infarcted lung and required completion pneumonectomy. Development of collateral circulation to bypass the occluded PA may occur but is often insufficient to support the affected lung tissue. Unless the patient is medically unfit, resection of the ischaemic lung should be undertaken.

Factors Affecting

Factors affecting perfusion distribution in oleic acid pulmonary edema were examined in 28 anesthetized open-chest dogs. Sixteen had unilobar oleic acid edema produced by left lower lobe pulmonary artery infusion of 0.03 ml/kg of oleic acid, and 12 had the same amount of edema produced by left lower lobe endobronchial instillation of hypotonic plasma. Lobar perfusion (determined from flow probes) and lobar shunt (determined from mixed venous and lobar venous blood) were measured at base line, 1.5 h after edema, and 10 min after 10 cmH2O positive end-expiratory pressure (PEEP). Fourteen dogs (8 oleic acid, 6 plasma) received sodium nitroprusside (11.72 +/- 7.10 micrograms X kg-1 X min-1). Total and lobar shunts increased to the same extent in all animals. Lobar perfusion decreased by 49.8 +/- 4.8% without nitroprusside and 34.0 +/- 3.6% with nitroprusside in the oleic acid group, corresponding values being 40.3 +/- 0.8% and 26.4 +/- 1.7% in the hypotonic plasma group. PEEP returned perfusion and shunt to base line. In oleic acid edema, most of the decreased perfusion results from mechanical effects of the edema, a smaller fraction results from other vascular effects of the oleic acid, and approximately 30% is reversible by nitroprusside. PEEP normalizes the perfusion distribution.

AbstractThe prognosis of microscopic polyangiitis (MPA) with interstitial lung disease (ILD) is significantly worse than that of MPA without ILD. However, the clinical characteristics in MPA-ILD, especially poor prognostic factors, are not elucidated. We evaluated demographic, clinical, laboratory, and radiological findings, treatments, and outcomes of 80 patients with MPA, and investigated prognostic factors of respiratory-related death in patients with myeloperoxidase (MPO)-anti-neutrophil cytoplasmic antibody (ANCA) positive MPA-ILD. Ground-glass opacity and fibrosis were evaluated as scores on high-resolution computed tomography (HRCT). The presence of ILD was consistent with a high risk of respiratory-related death (hazard ratio, 4.8; P = 0.04). Multivariable logistic regression analyses using propensity scoring showed right or left lower lobe fibrosis score to be significantly associated with respiratory-related death (P = 0.0005 and 0.0045, respectively). A right or left lower lobe fibrosis score ≥ 2, indicating the presence of honeycombing at 1 cm above the diaphragm, was determined to be the best cut-off value indicating a poor prognosis. The 5-year survival rate was significantly lower in patients with right or left lower lobe fibrosis score ≥ 2 (survival rates: 37% and 19%, respectively) than those with a score < 2 (71% and 68%, respectively) (P = 0.002 and 0.0007, respectively). These findings suggest that the presence of honeycomb lesions in bilateral lower lobes on chest HRCT was associated with respiratory-related death in patients with MPO-ANCA positive MPA-ILD.

Background: In patients with chronic pulmonary microaspiration (CPM) the recognition of high-resolution computed tomographic (HRCT) findings and their pattern is important. Objective: To investigate the HRCT detections in patients with CPM. Materials and Methods: This descriptive study enrolled 100 consecutive patients with CPM underwent HRCT of the lungs between 2017 and 2018 in Tehran and Zahedan Hospitals and private centers. The required variables were recorded for each patient with a questionnaire. Subsequently, HRCT was performed and abnormalities were then reported by two radiologists. Results: Most of patients exhibited bronchial thickening in 33.6% of cases, followed by ground-glass opacity (12.4%), em- physema (11.1%), and bronchiectasis (8.5%). In addition, the most common HRCT findings were found in left lower lobe (LLL) (37.1%), followed by right lower lobe (RLL) (35.9 %), right upper lobe (RUL ) (6,2%), and left upper lobe (LUL) (6%). Conclusion: Our data showed the most common findings in HRCT were bronchial thickening ground-glass opacity, em- physema, and bronchiectasis, where these findings was dominantly found in LLL, RLL, RUL, and LUL, indicating its high tendency to dependent areas. Keywords: Imaging; high-resolution computed tomographic; chronic lung microaspiration.
