ABSTRACT
Objective To analyze three-dimensional imaging characteristics and advantages for severe portal vein stenosis after liver transplantation, and to evaluate clinical efficacy of portal vein stent implantation. Methods Clinical data of 10 patients who received portal vein stent implantation for severe portal vein stenosis after liver transplantation were retrospectively analyzed. Imaging characteristics of severe portal vein stenosis, and advantages of three-dimensional reconstruction imaging and interventional treatment efficacy for severe portal vein stenosis were analyzed. Results Among 10 patients, 3 cases were diagnosed with centripetal stenosis, tortuosity angulation-induced stenosis in 2 cases, compression-induced stenosis in 2 cases, long-segment stenosis and/or vascular occlusion in 3 cases. Three-dimensional reconstruction images possessed advantages in accurate identification of stenosis, identification of stenosis types and measurement of stenosis length. All patients were successfully implanted with portal vein stents. After stent implantation, the diameter of the minimum diameter of portal vein was increased [(6.2±0.9) mm vs. (2.6±1.7) mm, P<0.05], the flow velocity at anastomotic site was decreased [(57±19) cm/s vs. (128±27) cm/s, P<0.05], and the flow velocity at the portal vein adjacent to the liver was increased [(41±6) cm/s vs. (18±6) cm/s, P<0.05]. One patient suffered from intrahepatic hematoma caused by interventional puncture, which was mitigated after conservative observation and treatment. The remaining patients did not experience relevant complications. Conclusions Three-dimensional visualization technique may visually display the location, characteristics and severity of stenosis, which is beneficial for clinicians to make treatment decisions and assist interventional procedures. Timely implantation of portal vein stent may effectively reverse pathological process and improve portal vein blood flow.
ABSTRACT
Lacrimal gland adenoid cystic carcinoma (LGACC) is the most common primary malignant epithelial tumor of the lacrimal gland and has the characteristics of high recurrence rate, neurotropic growth, and risk of distant metastasis. The clinical manifestation is mainly a mass in the lacrimal gland area with a poor specificity. The combination of MRI and CT is important in the diagnosis of LGACC, and PET/CT is of great value in determining the nature and metastasis of LGACC. Histopathological examination is the gold standard for diagnosis, and the type of histopathology is significant for predicting the prognosis of patients. At present, the most commonly used treatment for LGACC is surgical resection combined with postoperative local radiotherapy. However, the overall prognosis is poor after active treatment because the pathogenesis of LGACC remains unclear. This article will combine relevant literature and the author's clinical experience to review the epidemiology, clinical manifestations, imaging examination, histopathological changes, treatment, and prognosis of LGACC. Results will contribute to improve the quality of diagnosis and treatment and the prognosis of patients.
ABSTRACT
Objective To explore the application effect of three－point small incision in double eyelid plasty. Methods From October 2013 to October 2016,160 patients with double blepharoplasty in the Central Hospital of Linfen were selected and randomly divided into traditional group(treated with traditional surgery) and small incision group(treated with three－point small incision in double eyelid plasty) according to the digital table,with 80 cases in each group. All patients were followed up for half a year. The pain score at postoperative 24h,wound healing time, swelling regression time,satisfaction score and the incidence of complications were compared between the two groups. Results The pain score at postoperative 24h of the small incision group was (2. 75 ± 0. 32)points,which was signifi-cantly lower than (4. 15 ± 0. 41)points of the traditional group,and the swelling subsided time,postoperative incision healing time of the small incision group were (4. 24 ± 0. 41)d,(5. 27 ± 0. 32)d,respectively,which were significantly shorter than those of the traditional group[(6. 12 ± 0. 32) d,(8. 17 ± 0. 45) d],the differences were statistically significant(t=24. 076,32. 331,46. 974,all P ＜0. 05). After follow －up for half a year,the satisfaction score of patients in the small incision group was ( 89. 75 ± 4. 32 ) points, which was significantly higher than ( 82. 15 ± 4. 10)points of the traditional group,the difference was statistically significant(t=11. 413,P＜0. 05). The incidence rate of complications in the small incision group was 0. 00% , which was significantly lower than 7. 50% in the traditional group(χ2=6. 233,P ＜0. 05). Conclusion The effect of three －point small incision intervention on double eyelid plasty patients is significant,and the satisfaction rate of the patients is higher.
ABSTRACT
Objective To compare the curative effect of open and minimally invasive treatment of acute closed achilles tendon rupture with 5 years followed-up study.Methods From September,2010 to January,2012,28 patients with acute closed Achilles tendon rupture in our hospital were followed up for 5 years.There were 21 males and 7 females.Minimally invasive percutaneous suture in 11 cases;open suture in the treatment of 17 cases.The patients were followed up at 6 months,1 year,2 years,3 years,4 years,and 5 years after AOFAS and ATRS score.Results The follow-up time ranged from 60 to 72 months.All incisions healed by first intention and no incision related complications occurred.2 groups of patients with ATRS score at 6 months after operation:the open group was 81.23±3.99,minimally invasive percutaneous group of 88.27±4.27,the difference between the two groups was statistically significantly.After 1 year,there was no significant difference in the scores between the two groups.Two groups of patients with AOFAS score at 6 months after operation:the open group was 69.00±6.23,minimally invasive percutaneous group of 79.27±4.83,the difference between the two groups was statistically significantly.At one year after operation,the open group was 85.53±3.38,and the minimally invasive group was more than 89.90±3.38.The difference between the two groups was statistically significantly.After 2 years,there was no significant difference in the scores between the two groups.Conclusion There is no significant difference between the 2 years after surgery in the treatment of acute closed Achilles tendon rupture or open surger.
