Objective To evaluate repair and reconstructionof the femoral pseudoaneurysm caused by drug injection. Methods From May 2000 to May 2005, 15 cases of femoral pseudoaneurysm caused by drug injection underwent operation treatment. All patients were male, aging 20-36 years. The disease course was 18-52 days(mean 35 days) and the course of druginjection was 3-17 months. The locations were the left side in 5 cases and theright side in 10 cases. After having been bandaged with pressure and supportedwith nutrition, they had been all operated. One case received fistula repair, and 14 cases received vascular grafting with ePTFE man-made blood vessel. Results The wounds healed by the first intention in 14 cases. All limbs survived. The complexion, temperature and response of involved leg were in gear. The postoperative color ultrasound Doppler detection showed that all the vascular grafts were of patency. The function of the involved limbs restored to normal. Conclusion Complete debridement, vascular reconstruction and better microsurgery skill were the key factors of treating successfullythe femoral pseudoaneurysm caused by drug injection.
ObjectiveTo determine the characters of symptomatic pancreatic pseudocyst due to acute pancreatitis and effects of surgical treatment with two kinds of procedure （internal drainage or external drainage）. MethodsOne hundred and fifteen cases hospitalized during recent ten years were retrospectively analyzed.ResultsWe found that necrotic tissue existed in the pseudocyst in most cases and infection might occur in these pseudocyst. Although effect of two kinds of surgery was similar, the clinical course was different. The complications after surgery were fewer in patients underwent internal drainage than that with procedure of external drainage, and average hospital day was 7d in cases with internal drainage and 11d in cases with external one respectively. Surgery of internal drainage used in treatment was not only successful in noninfectious and single pseudocyst, but in infectious or multiple seudocyst.ConclusionInternal drainage should be used in most cases and considered as the first selection in surgery of pseudocyst due to acute pancreatitis.
ObjectiveTo observe the multi-modal fundus imaging features of subretinal drusenoid deposit (SDD) in age-related macular degeneration (AMD), and observe image features. MethodsA prospective clinical study. From December 2019 to December 2023, 65 patients (104 eyes) with a diagnosis of AMD-SDD by spectral domain optical coherence tomography (SD-OCT) examination in Shandong Eye Hospital were included. All eyes were examined by best corrected visual acuity (BCVA), traditional color fundus photography (CFP), ultra-wide-angle scanning laser fundus imaging (UWF), multicolor scanning laser fundus imaging (MC) and SD-OCT. The standard MC images were obtained by using Spectralis HRA+OCT for MC examination. The multi-mode image characteristics of SDD were analyzed retrospectively. Area under curve (AUC) was used to evaluate the sensitivity and specificity of CFP, MC and UWF in detecting SDD. ResultsAmong 65 patients with SDD, 29 cases of males (52 eyes) and 36 cases of females (52 eyes) was included. There were 26 patients with unilateral SDD and 39 patients with bilateral SDD. The average age was (71.74±10.97) years. The early, middle and late stages of AMD were 31 (29.8%, 31/104), 24 (23.1%, 24/104), 49 (47.1%, 49/104) eyes, respectively. The SDD detected by CFP, MC and UWF was 76 (73.1%, 76/104), 94 (90.4%, 94/104), 96 (92.3%, 96/104) eyes. CFP showed that the edge of SDD in the macular area was blurred. UWF showed that the dot and the ribbon SDD were light yellow pale discrete deposits and light yellow interlaced network deposits respectively. MC showed the dot SDD had a strong yellow-green circular reflection, while the edge of the ribbon SDD was surrounded by a weak reflection, and the boundary was clear. SD-OCT showed that SDD had strong reflection signal, which was located between the retinal pigment epithelium layer and the photoreceptor cell layer. The dot SDD could break through the ellipsoid zone and caused slight uplift or interruption of the external membrane, showing a cone-like strong reflection signal. While the ribbon SDD showed a continuous "hill-like" protrusion, which hardly broke through ellipsoid zone. The sensitivity and specificity of CFP, MC and UWF for SDD were 73.1%, 90.4%, 92.3% and 61.1%, 94.4% and 83.3%, respectively. ConclusionsMC and UWF show high sensitivity and specificity in diagnosing AMD-SDD, which is superior to CFP. SD-OCT can effectively reveal the location and morphoLogical characteristics of SDD under retina.
目的探讨毒品注射所致感染性假性动脉瘤的特点及治疗方法与临床疗效。方法回顾性分析我院血管外科2009年1月至2010年6月期间收治的13例感染性假性动脉瘤吸毒患者的临床资料，采用切除瘤体及周围炎性组织、瘤腔清创及动脉结扎或人工血管置换术，观察移植效果及并发症发生情况。结果13例手术均获成功，无一例发生肢体坏死； 伤口一期愈合5例，二期愈合8例； 7例发生程度不等的淋巴瘘。随访2～12个月（平均7个月），其中1例术后2个月瘤腔下端感染形成脓肿伴出血，行切开引流痊愈； 2例术后4个月人造血管感染行人造血管摘除，切口换药痊愈； 有2例左肘部假性肱动脉瘤直接行血管结扎，未用人工血管移植； 余8例复查B超显示移植血管通畅，无血栓形成。结论彻底清创、血管移植、控制感染是治疗感染性假性动脉瘤的有效方法。
