RESUMO
Objective To discuss the application of bare-stent“chimney”technique in treating aortic dissection associated with left common carotid rupture, and to evaluate its therapeutic effect. Methods The clinical data of 7 patients with aortic dissection accompanied with left common carotid rupture, who were admitted to Qinghai Provincial People’s Hospital during the period from February 2012 to March 2014 to receive endovascular isolation operation treatment with bare-stent “chimney” technique, were retrospectively analyzed. When the rupture of aortic dissection was occluded with covered-stent, the left common carotid rupture was isolated with “chimney”bare-stent to reconstruct the blood flow of left common carotid artery. CT angiography was performed 2 weeks after the operation to check if there was any complication such as endoleak, stent migration, etc. Results The technical success rate of endovascular isolation operation was 100%. No type I endoleak occurred. The patients were followed up for 1-13 months, the covered stent in the aorta was in good position, and the “chimney” bare-stent in the left common carotid artery was patent. No complications such as endoleak, stent migration, etc. occurred. Conclusion Bare-stent“chimney”technology can provide treatment opportunity for the patients suffering from left common carotid artery rupture accompanied by aortic dissection; the rupture can be completely obstructed and the blood flow can be reconstructed. The short-term effect is satisfactory, although the long-term effect needs to be further studied.
RESUMO
Objective To evaluate the efficacy and safety of CT-guided percutaneous celiac plexus block (NCPB) using 25 G controllable curved needle together with 22 G straight needle in treating refractory carcinomatous upper abdominal pain. Methods A total of 18 patients with advanced refractory carcinomatous upper abdominal pain were enrolled in this study. The carcinomatous upper abdominal pain failed to the three-step analgesic therapy. Guided by CT scan, percutaneous injection of ethanol with a 25 G controllable curved needle to destroy celiac plexus was carried out in all patients. According to WHO pain relief standards, the relieving degree of pain was evaluated before NCPB and 2 weeks, one, 2, 3 and 6 months after NCPB. The results were analyzed. Results The technical success rate was 100%. The short-term (within 2 weeks) efficacy rate was 88.8%and the complete remission rate was 38.8%. The long-term (over 3 months) efficacy rate was 50% and the complete remission rate was 20%. No severe complications occurred. Conclusion For refractory carcinomatous upper abdominal pain, CT-guided percutaneous celiac plexus block is a simple, safe and effective treatment.
