Degos disease complicated by constrictive pericarditis in remote phase: a case report.

BACKGROUND: Degos disease, also known as malignant atrophic papulosis, is characterised by cutaneous manifestations due to chronic thrombo-obliterative vasculopathy. There have been reports of the rare late-onset Degos disease complicated by constrictive pericarditis (CP). This study reports a case of CP caused by Degos disease that developed 20 years after diagnosis. CASE PRESENTATION: A 62-year-old woman who had been taking aspirin for 20 years for Degos disease was hospitalised for worsening of heart failure. The patient was diagnosed with CP and underwent pericardiectomy. Pathological findings suggested the involvement of Degos disease. The postoperative course was uneventful, and her heart failure and Degos disease did not worsen. CONCLUSIONS: The study findings suggests that Degos disease can cause long-term CP. Aspirin effectively inhibited the progression of Degos disease, and surgical treatment was necessary when heart failure due to CP was refractory to treatment.

Risk Factors for Progression of Distal Deep Vein Thrombosis.

BACKGROUND: There is insufficient evidence regarding the optimal treatment method for distal deep vein thrombosis (DVT), including indications for anticoagulation therapy. Treatment results of patients with distal DVT were evaluated to clarify the risk factors that result in extension of distal DVT to the proximal vein and indications for anticoagulation therapy.Methods and Results:Among 430 patients with DVT between January 2018 and December 2019, 253 were diagnosed with distal DVT; 41 patients who had already started anticoagulation therapy were excluded, and the remaining 212 were included as study subjects. Anticoagulation therapy was not started immediately; conservative treatment with compression stockings was performed. Ultrasonography after 2 weeks revealed thrombus disappearance in 39 patients (21%), and thrombus reduction in 38 patients (20%). In contrast, extension of thrombus to the proximal vein was noted in 12 patients (6.3%) and anticoagulation therapy was commenced. After 3 months, the thrombus had disappeared in 75 patients (52%). No patient developed pulmonary thromboembolism during follow-up. With respect to the risk factors for extension to proximal vein during conservative treatment, active cancer (P=0.03), prolonged bed rest (P<0.01), and D-dimer level >8µg/mL (P=0.01) were identified. CONCLUSIONS: It is reasonable to consider anticoagulation therapy in distal DVT patients with active cancer, prolonged bed rest or high D-dimer level.

Watch-and-wait strategy for type A intramural haematoma and acute aortic dissection with thrombosed false lumen of the ascending aorta: a Japanese single-centre experience.

OBJECTIVES: In this study, we investigated the early and midterm outcomes of initial watch-and-wait strategy for Stanford type A intramural haematoma and acute aortic dissection with thrombosed false lumen of the ascending aorta in patients with a maximum aortic diameter of ≤50 mm, pain score of ≤3/10 and no ulcer-like projection in the ascending aorta. METHODS: Inpatient and outpatient records were retrospectively reviewed. RESULTS: Of the 81 patients with type A intramural haematoma and acute aortic dissection with the thrombosed false lumen of the ascending aorta between April 2011 and April 2019, a watch-and-wait strategy was selected in 46 patients. The mean age of the patients was 68 years, and 22 (48%) patients were female. Ten patients underwent emergency pericardial drainage for cardiac tamponade at the time of presentation and 8 patients underwent aortic repair during hospitalization for new ulcer-like projection, re-dissection or rupture. In-hospital mortality occurred in 2 (4%) patients. During follow-up, survival at 1 and 2 years was 95% and 92%, respectively. There was no significant difference in survival or aortic events between patients in whom the watch-and-wait strategy and emergency surgical treatment were indicated. CONCLUSIONS: The early and midterm outcomes of the initial watch-and-wait strategy were favourable for type A intramural haematoma and acute aortic dissection with the thrombosed false lumen of the ascending aorta in Japanese patients with a maximum aortic diameter of ≤50 mm, pain score of ≤3/10 and no ulcer-like projection. Further study is required to show the safety of this strategy.
