Wegener' granulomatosis is an autoimmune diseases, often involving the lung and kidney, has a high mortality rate in nontreatment patients. The low incidence and nonspecific features, often lead to misdiagnosis and delayed treatment. This paper reported the diagnosis and treatment of a 55-year-old female patient with primary Wegener' granuloma of the lung diagnosed by percutaneous lung biopsy of pulmonary nodules, and reviews the relevant literature.

Objective     To evaluate the early clinical effect of reimplantation in the treatment of bicuspid aortic valve (BAV) with aortic root aneurysm. Methods     The clinical data of 25 patients with BAV and aortic root aneurysm [mean diameter: 45-63 (52.68±5.55) mm] undergoing reimplantation in West China Hospital from November 2019 to May 2021 were retrospectively reviewed. There were 22 males and 3 females. The mean age was 15-65 (50.00±13.10) years and body surface area was 1.79±0.23 m2. Results    The pathological classification of BAV malformation was confirmed during the operation: Type 0 in 3 patients and Type 1 in 22 patients. There were 12 patients undergoing cusp central plication, and 2 patients were sutured with a closed fusion crest. Postoperative valve leaflet coaptation height was 0.78±0.15 cm, and effective height was 1.27±0.19 cm. In operation, maximum aortic valve flow velocity was 1.65±0.42 m/s, pressure difference was 5.46±3.05 mm Hg, and aortic valve annulus diameter was 21.32±0.95 mm. Cardiopulmonary bypass time was 225.84±35.34 min, and aortic block time was 189.60±26.51 min. In-hospital time was 11.64±3.07 d, ICU stay time was 2.64±0.99 d, and mechanical ventilation time was 1.48±0.87 d. The follow-up time was 17.20±4.70 months, and no death or major complications occurred during the follow-up in all patients. The cardiac function of the patients significantly improved postoperatively (P≤0.05). Echocardiography suggested that 12 patients had no aortic regurgitation, 10 minor aortic regurgitation, 3 mild aortic regurgitation, and no patients with moderate or more severe regurgitation. The diameter of the aortic sinus, left ventricular end-diastolic diameter and volume decreased during the follow-up, compared to preoperative ones (P≤0.05). The maximum flow velocity of the aortic valve was 1.54±0.36 m/s, and the pressure difference was 5.17±2.38 mm Hg during the follow-up. Conclusion    Reimplantation technology has a good clinical effect for highly selective BAV patients. It can effectively avoid long-term postoperative anticoagulation, but the maximum flow rate after surgery is slightly increased, which may be related to the configuration of BAV itself. While compared with valve replacement, the effect is still worthy of recognition.
