Résumé
A 57-year-old man, who had suffered chest, back and right leg pain about 10 years before, underwent CT and was found a chronic type B aortic dissection with an enlarged false lumen and a narrowed true lumen that was occluded at the infrarenal abdominal aorta. A conventional surgical repair seemed to be too high risk considering his comorbidities, thus we chose a staged hybrid repair. First, surgical repair of the abdominal aorta with an abdominal aortic fenestration was performed. Then, one month after the first operation, zone 2 thoracic endovascular aortic repair with left carotid-axillary artery bypass was performed. At the second operation, the stent graft was purposely deployed from zone 2 into Th12 level of a false lumen through the fenestration followed by coil embolization of a true lumen just distal to the entry tear. The postoperative course was uneventful and he had no complications at 6 months follow-up. Deploying stent graft into a false lumen could be a feasible option in case deploying into a true lumen is not suitable if the anatomical condition permits.
Résumé
Aortic dissection presents with acute chest or back pain. However, it can be asymptomatic in the acute phase with delayed symptomatic presentation or incidental diagnosis upon chest imaging. We report a case of acute type B aortic dissection subsequent to chronic type A aortic dissection which was difficult to distinguish from acute type A aortic dissection. A 45-year-old man was admitted to a hospital with sudden back pain. An enhanced chest CT revealed a suspected acute type A aortic dissection. The patient was transferred to our hospital and we performed an emergent total arch replacement. Intraoperative findings showed that there were two entries at the origin of the brachiocephalic artery and the left subclavian artery. The ascending aorta presented wall thickening but the descending aorta did not present wall thickening. Histopathologically, the adventitia was obviously thickened with dissection findings in the tunica media. Thus it was diagnosed as acute type B aortic dissection subsequent to chronic type A aortic dissection. Great caution should be taken in asymptomatic chronic aortic dissection.
Résumé
This case report aimed to evaluate the efficacy of applying VIABAHN endoprosthesis at the dissection re-entry of the right renal artery after thoracic endovascular aortic repair (TEVAR) in a patient with a chronic type B dissected thoracoabdominal aneurysm. A 78-year-old man was given a diagnosis of type B aortic dissection 5 years ago and underwent a successful TEVAR operation. Two years later, he developed complications such as chronic expanding aortic dissections ; thus, he underwent a second endovascular repair. Enhanced computed tomography (CT) scanning at the five-year follow-up after initial endovascular repair showed a 58-mm diameter thoracoabdominal dissected aneurysm. It also showed an apparent entry point dissection arising from the lower thoracic aorta and a re-entry point at the base of the right renal artery. Although the right renal artery was affected by the dissecting false lumen, all other abdominal branches were intact. He was treated with VIABAHN via occlusion of the re-entry of the dissection and reconstruction of the right renal artery. The patient recovered uneventfully and was discharged 10 days after the operation. Postoperative enhanced CT scanning showed that the aortic false lumen was completely thrombosed, and the right renal arterial flow had significantly improved. Although TEVAR is the standard treatment in acute complicated type B dissections, its role in chronic type B dissections remains controversial. Our technique of using VIABAHN for the reconstruction of the right renal artery showed promising results for patients with chronic type B dissections.

Objective To summarize the clinical outcomes and surgical indications for chronic type A aortic dissection (CTAD) by using Sun's procedure with preservation of autologous brachiocephalic vessels.Methods From September 2010 to December 2013, 23 patients with CTAD underwent Sun's procedure with preservation of autologous brachiocephalic vessels under moderate hypothermic circulatory arrest combined with selective cerebral perfusion in our center .The data was collected and analysed retrospectively.There were 20 males and 3 females patients with a mean age of(49.91 ±10.05) years.Preopera-tive comorbidities included Marfan syndrome in 1 patient, isolated left vertebral artery in 1, hypertension in 19, coronary artery disease in 2, heart dysfunction in 1, renal insufficiency in 1, mitral regurgitation in 1, and pulmonary infection in 1.Previous operation history included thoracic endovascular aortic repair in 3, percutaneous coronary intervention in 1, aortic valve re-placement in 1, Bentall procedure in 1, and coronary artery bypass grafting in 1.Results The average operation time, car-diopulmonary bypass time, aortic cross clamping time and selective cerebral perfusion time was(6.43 ±1.03) h,(167.07 ± 49.62) min,(80.74 ±29.00) min, and(27.35 ±6.03) min, respectively.Concomitant procedures included Bentall proce-dure in 6 patients, ascending aorta replacement in 17, ascending aorta-femoral artery bypass in 1, mitral valvuloplasty in 1, and CABG in 1.There were 2(8.70%) in hospital deaths.Three patients suffered temporary renal dysfunction, and 1 with re-nal failure recieved continuous renal replacement therapy .Postoperative hypoxemia were found in 2 patients, and 1 of them re-ceived reintubation.These patients recovered before discharge.The mean follow-up time was(52.52 ±9.89) months with a follow-up rate of 95.23%(20/21).One patient suffered cerebral embolism but recovered soon after treatment.The others were free from any complications.Conclusion Sun's procedure with preservation of autologous brachiocephalic vessels simplified the aortic arch surgery and obtained satisfactory outcomes for suitable patients with CTAD , but surgical indications should be strictly considered.
Résumé
<p>We report a case of ruptured chronic type B aortic dissecting aneurysm that was successfully treated with the Candy plug technique to exclude a false lumen. A 57-year-old man had undergone abdominal fenestration for complicated acute type B aortic dissection previously. He then underwent debranching TEVAR for an impending rupture because of a dilated thoracic aortic dissecting aneurysm in 2014. After one year, the aneurysm was ruptured because of continuous distal flow of the false lumen. We performed TEVAR using the Candy plug technique, and he was discharged on the 11th postoperative day. The false lumen diameter was reduced. TEVAR using the Candy plug technique for chronic type B aortic dissection was thought to be useful in high-risk patients, but we need more careful observation.</p>
Résumé
With a long duration of the CHB, patients who have economic pressures and physical problems will get changes in their psychological status, which are involved in the development of the disease. Moreover, poor thera-py compliance and insight of their disease, negative mood of anxiety and depression also have effects the prognosis of disease. Therefore, mental factors play a vital important role in the development and prognosis of CHB patients, health education and mental intervention are the most effective way to avoid the psychological disorder of patients.

Objective To observe the clinical effects of treating chronic type B hepatitis with Gankang Granule combined with poly I-C and immune ribonucleic acid. Methods A total of 100 cases of chronic type B hepatitis were randomly recruited into a control group and a treatment group, 50 cases in each group. The control group was treated with poly I-C and immune ribonucleic acid, while the treatment group was treated with Gankang Granule on the basis of the control group. Results Symptoms in both groups were improved. 23 eases in the treatment group showed negative value of HBeAg,contrasting to 13 cases in the control group. 38 cases in the treatment group turned to be negative value of HBV- DNA, higher than the number of 23 cases in the control group. The treatment group demonstrated a significantly better therapeutic results than the control group (χ2 value was 6.267 and 6.345 respectively, both P＜0.05). Conclusion Gankang Granule combined with poly I-C and immune ribonucleic acid can obviously improve hepatic functions and symptoms of chronic type B hepatitis,shorten the course of disease, and increase the rate of negative value of HBeAg and HBV- DNA.

Résumé
In Oita prefecture, where ATL is relatively endemic, the authors carried out hematology analysis using an E-4000 hematology analyzer in a health examination. This analysis screened a group of 104 males and 181 females out of randomly collected 11, 568 persons in terms of a higher (exceeded 50%) W-SCR rate (i. e. lymphocyte rate in cell size distribution). The collected peripheral blood smears from this group were further subjected to the examination of lymphocyte morphology.<BR>Abnormal lymphocytes exhibiting dyscaryosis, such as indentation or lobulation, were observed in 11 cases, and further examination of anti-ATLA antibody and earlobe blood smears revealed eight suspected cases of ATL-related condition.<BR>Clinical symptoms characteristic of ATL were not observed in the above eight cases, though the anti-ATLA antibody titer measured by the ELISA method increased by more than 25. In one case, being diagnosed as chronic-type ATL, abnormal lymphocytes amounted to 70% and the leukocyte count was 28, 000/μl. In the other seven cases, abnormal lymphocytes amounted to only 1-11%, and the leukocyte counts ranged from 5, 300 to 11, 100/μl, which was almost within the normal limits.<BR>The method in reported as an useful means for screening cases of nonsymptomatic chronic or smoldering type ATL through a health examination.
