  • Surgical Treatment of Infected Femoral Artery Pseudoaneurysm

    Objective To evaluate surgical treatment of infected femoral artery pseudoaneurysm. Methods The data on surgical treatment of 45 patients with infected femoral artery pseudoaneurysm admitted from January 2003 to June 2008 were analyzed retrospectively. Fourty-three patients underwent operative treatment including excision of infected femoral artery pseudoaneurysm, exhaustive debridement and bypass graft with vascular prosthesis. Two patients were unavoidable to undergo removing of infected femoral artery pseudoaneurysm and ligating the proximal and distal artery of pseudoaneurysm because of severe infection and large volume. Results The patients were followed up from 3 to 12 months (mean 7.82 months). The limbs of all the patients underwent bypass graft with vascular prosthesis were salvaged successfully, patients of which had secondary wound healing and had not intermittent lameness. One of two patients performed ligation of artery was salvaged successfully but had severe intermittent lameness, another patient underwent high amputation above knee because of ischemic gangrene. Conclusion For infected femoral artery pseudoaneurysm, the operative treatment including excision of infected femoral artery pseudoaneurysm, exhaustive debridement and bypass graft with vascular prosthesis is effective and safe.

  • Construction and Gene Silence Function of Gene Silence Adenovirus Vector Plasmid Targeting Both TG2 and Mertk Synchronously

    Objective To construct gene silence adenovirus vector targeting both transglutaminase 2 (TG2) and Mer receptor tyrosine kinase (Mertk) synchronously and detect the gene silence function of it. Methods The interfering plasmids targeting TG2 protein and Mertk protein were constructed firstly, then the H1 promoter and RNA interfering (RNAi) sequence were cut and ligated to pAdTrack for constructing pAdTrack/TG2/Mertk. The pAdTrack/TG2/Mertk was transfected into BJ5183 bacterial cells which contained pAdEasy-1, then the plasmid was detected by enzyme digestion after recovery. Adenovirus were harvested after that pAdTrack/TG2/Mertk was infected into HEK293 cells. The virus titer was measured after repeated amplification. The RAW264.7 cells were infected by pAdTrack/TG2/Mertk, pAdTrack/TG2, pAdTrack/Mertk, and pAdTrack/green fluorescent protein (GFP), respectively. Then the expression levels of TG2 protein and Mertk protein of mouse macrophages were detected by Western blot after infection. Results The virus titer of pAdTrack/TG2/Mertk plasmid was 6.13×1010GFU/mL. The pAdTrack/TG2/Mertk plasmid which contained 2 promoters and 2 RNAi sequences was identified successfully by enzyme digestion. Compared with pAdTrack/GFP group and pAdTrack/Mertk group (there was no significant differece between the 2 groups), the expression levels of TG2 protein of mouse macrophages which infected with pAdTrack/TG2/Mertk or pAdTrack/TG2 decreased obviously (P<0.01), but there was no significant difference between the later 2 groups. Compared with pAdTrack/GFP group and pAdTrack/TG2 group (there was no significant difference between the 2 groups), the expression levels of Mertk protein of mouse macrophages which infected with pAdTrack/TG2/Mertk or pAdTrack/Mertk decreased obviously too (P<0.01), but there was no significant difference between the later 2 groups. Conclusion Gene silence adenovirus vector plasmid targeting both TG2 and Mertk synchronously is constructed successfully, and the pAdTrack/TG2/Mertk can reduce the expressions of TG2 protein and Mertk protein of mouse macrophages obviously.

  • Clinical Analysis of Catheter-Directed Thrombolysis Combined with Vena Cava Filter for Deep Venous Thrombosis of Lower Extremity

    Objective To explore the therapeutic effect of catheter-directed thrombolysis combined with vena cava filter on deep venous thrombosis (DVT) of lower extremity.Methods The clinical data of 65 patients with DVT of lower extremities from January 2008 to August 2009 were analyzed retrospectively, whose course of diseases were not more than 7 d and clinical type included central type and mixed type. Thirty-two cases were treated with catheter-directed thrombolysis combined with vena cava filter, while administrating treatment of anticoagulation and activating blood circulation to dissipate blood stasis, which were named as study group. Thirty-three cases were treated traditionally with thrombolysis, anticoagulation, and activating blood circulation to dissipate blood stasis, which were named as control group. The course of therapy was continued 10-14 d, then the efficacy in two groups patients was evaluated. Results It was (7.35±1.42) cm that circumference difference before treatment between affected extremties and unaffected extremties in study group, which of 3, 7, and 14 d after treatment was (4.21±1.12) cm, (2.87±0.98) cm, and (1.22±1.02) cm, respectively. Circumference difference between before and after treatment had significant difference in study group (Plt;0.01). It was (6.97±1.27) cm that circumference difference before treatment between affected extremties and unaffected extremties in control group, which of 3, 7, and 14 d after treatment was (5.72±1.31) cm, (4.58±0.88) cm, and (3.18±1.24) cm, respectively. Circumference difference between before treatment and 3, 7, and 14 d after treatment had significant difference in control group (Plt;0.05 or Plt;0.01). Circumference difference before treatment in two groups had no significant difference (Pgt;0.05). Circumference difference after treatment at different time points in two groups was significantly different, respectively (Plt;0.01). Circumference difference after treatment at different time points in study group was significantly less than that in control group, respectively (Plt;0.01). After 14 d, complete recanalization rate (71.88%, 23/32) and cure rate (71.88%, 23/32) of iliofemoral vein in study group were significant higher than that (36.36%, 12/33) in control group (Plt;0.01). No pulmonary embolism occurred. Conclusion In terms of ideal therapy targets of DVT of lower extremity, the catheterdirected thrombolysis combined with vena cava filter is obviously superior to traditional thrombolysis treatment.

  • Discussion and clinical application experience of laparoscopic spleen-preserving distal pancreatectomy technology

    ObjectiveTo summarize the key technical points, applicability, feasibility, and safety of laparoscopic spleen-preserving distal pancreatectomy (LSPDP).MethodA retrospective analysis was performed for the clinical data of 22 patients who were admitted to the Affiliated Hospital of North Sichuan Medical College from September 2016 to November 2019, all patients planned to receive LSPDP.ResultsTwenty of the 22 patients successfully completed LSPDP, and 2 patients converted to laparotomy. One patient was transferred to laparotomy to suture the damaged splenic artery. The spleen was observed to have no ischemia and the spleen preservation operation was continued. One patient was converted to laparotomy due to the difficulty of dissecting the tail of the pancreas which caused by severe abdominal adhesion. The operation time of LSPDP patients was (191±86) minutes (170–480 min), intraoperative blood loss was (365±50) mL (200–1 000 mL), and postoperative hospital stay was (9.9±2.6) days (7–16 d). Six patients of pancreatic fistula occurred after operation, including 3 cases of biochemical fistula, which were cured and discharged after symptomatic treatment, 3 cases of grade B pancreatic fistula, who all improved after anti-inflammatory, acid suppression, enzyme suppression, and double catheter drainage. Twenty patients were interviewed after the operation, and the follow-up time was 3–24 months (median of 15 months). During the follow-up period, no patient had recurrence or metastasis.ConclusionsUnder the conditions of strict screening of suitable cases, adequate preoperative imaging evaluation, intraoperative fine manipulation, and the application of appropriate operating instruments and cutting closure devices, LSPDP is safe and feasible to treat benign tumors of the pancreatic body and tail and some borderline tumors. During the operation, attention should be paid to the reasonable treatment and protection of splenic arteries and veins.

  • Perioperative safety of laparoscopic pancreaticoduodenectomy in elderly patients

    ObjectiveTo investigate perioperative safety of laparoscopic pancreaticoduodenectomy (LPD) in elderly patients (age ≥70 years old).MethodsThe retrospective cohort study was conducted. The clinicopathologic data of the patients underwent LPD and open pancreaticoduodenectomy (OPD) in the Affiliated Hospital of North Sichuan Medical College from January 2016 to December 2019 were collected. The patients who met the inclusion and exclusion criteria were divided into LPD with aged ≥70 years old group (group A), OPD with aged ≥70 years old group (group B), and LPD with aged <70 years old group (group C). The baseline data, intraoperative situations, and postoperative situations were compared between the group A and group B, and between the group A and group C, respectively.Results① There were no statistic differences in the age, gender, body mass index, hemoglobin, albumin, and total bilirubin, American Society of Anesthesiologists (ASA) grade, and comorbidity index before operation between the group A and group B (P>0.05). However, there were statistic differences in the hemoglobin, albumin, ASA grade, and comorbidity index before operation between the group A and group C (P<0.05). ② There were no significant differences in the operation time between the group A and group B (P>0.05), but the intraoperative blood loss of the group A was significantly less than the group B (P<0.05). The operation time, intraoperative blood loss, and conversion rate had no significant differences between the group A and group C (P>0.05). ③ There were no significant differences in the pathological pattern, tumor size, R0 resection rate, reoperative rate, and postoperative 90 d mortality between the group A and group B, and between the group A and group C, respectively. For the elderly patients, cases in the ICU, overall complications, specific complications (except for delayed gastric emptying) and Clavien-Dindo classification of complication after operation had no significant differences between the group A and group B (P>0.05), but there were more harvesting lymph nodes, lower postoperative pain score, shorter postoperative hospital stay, and less delayed gastric emptying cases in the group A than the group B (P<0.05). For the patients accepted LPD, there were no significant differences in the harvesting lymph nodes, postoperative pain score, postoperative hospital stay, and specific complications (except for pulmonary infection rate) between the group A and the group C (P>0.05), but the postoperative cases in the ICU were more, pulmonary infection rate was higher, overall complications rate and the ratio of Clavien-Dindo Ⅲ–Ⅳ classification of complication were higher in the group A as compared with the group C (P<0.05). ConclusionCompared with OPD, LPD might have some advantages in blood loss, harvesting lymph nodes, and recovery after surgery, even though perioperative safety of LPD in elderly patients is inferior to younger patients.
