ABSTRACT

Objective To explore the feasibility of rapid and sutureless anastomosis of artificial vascular replacement of abdominal aorta in dog models using magnetic compression anastomosis (MCA) technique. Methods Twelve healthy adult crossbred dogs were evenly divided into the MCA and hand suturing (HS) groups according to the anastomosis method between abdominal aorta and artificial blood vessels. The intraoperative duration of abdominal aorta occlusion, intraoperative condition of anastomotic stoma and postoperative imaging examination of anastomotic stoma were compared between two groups. Results The intraoperative duration of abdominal aorta occlusion in the MCA group was significantly shorter than that in the HS group [(5.2±2.3) min vs. (24.4±4.3) min, P < 0.001]. No anastomotic leakage of blood or anastomotic stenosis occurred in the MCA group during the operation. Intraoperative anastomotic leakage of blood occurred in all of the 6 dogs in the HS group. Among them, 1 dog died of excessive blood loss, and 2 dogs experienced mild anastomotic stenosis due to repeated repair. Postoperative color Doppler ultrasound and angiography showed smooth blood flow at the anastomotic stoma without stenosis or thrombosis in the MCA group. In the HS group, 4 dogs presented with anastomotic stenosis on angiography at postoperative 4 weeks. Conclusions MCA technique may achieve rapid and sutureless anastomosis of artificial vascular replacement of abdominal aorta in dog models, which reduces the incidence of anastomotic complications and accelerates postoperative recovery.

ABSTRACT

Objective:To investigate and compare the efficacy and safety of percutaneous mechanical thrombectomy (PMT) combined with catheter directed thrombolysis and catheter directed thrombolysis alone in the treatment of acute lower extremity deep venous thrombosis.Methods:Retrospective analysis of clinical data of 69 patients with acute lower extremity deep venous thrombosis who met the inclusion criteria of this study from January 2018 to December 2018 in department of vascular surgery, People′s Hospital of Xinjiang Uygur Autonomous Region was performed. There were 35 males and 34 females, with an average age of 59 years and an age rang of 20 to 80 years. Patients were divided into PMT combined catheter directed thrombolysis treated group ( n=38) and catheter directed thrombolysis treated group ( n=31) according to different methods of intra-luminal thrombolysis. The thrombolysis time, dosage of urokinase, thrombotic clearance rate, perimeter difference of suffered limb, and total number of adverse events during perioperative period between two groups were recorded. At 1 month, 3 months, and 6 months after discharge, patients underwent an ultrasonographic examination of lower extremity vessels to check and evaluate residual thrombolysis and thrombosis recurrence by outpatient review. The quantitative data in the two groups were expressed as mean±standard deviation( Mean± SD), t test was used for comparison between groups. Enumeration data in the two groups were expressed as percentage (%) and χ2 test was used for comparison between groups. Results:The thrombolysis time of PMT combined catheter directed thrombolysis treated group and catheter directed thrombolysis treated group were (3.7±2.1) d and (5.2±2.1) d, respectively. The differences between the two groups were statistically significant ( P=0.005). The dosage of urokinase were respectively (225.0±122.3)×10 4 units and (315.8±108.6)×10 4 units, the differences were statistically significant ( P=0.001). PMTⅠ, Ⅱ, Ⅲ thrombus clearance rate in patients with PMT combined catheter directed thrombolysis treated group were 18.4% (7/38), 73.7% (28/38), 7.9% (3/38), while 16.1% (5/31), 77.4% (24/31), 6.5% (2/31) were observed in patients with catheter directed thrombolysis treated group, with no statistically significant difference between the two groups ( P= 0.803, P=0.720, P=0.818). After a period of 48h thrombolytic therapy, the cross-section diameters of suffered thigh and calf were (2.16±0.87) cm and (1.38±0.66) cm in PMT combined catheter directed thrombolysis treated group respectively. While the cross-section diameters of suffered thigh and calf were (1.21±0.59) cm and (1.02±0.49) cm in catheter directed thrombolysis treated group respectively. The differences in the cross-section diameters of suffered thigh and calf were statistically significant after a period of 48h thrombolytic therapy ( P<0.001, P=0.014). Three cases (7.89%) had occurred adverse events during perioperative period in PMT combined catheter directed thrombolysis treated group, while there were 4 cases (12.90%) in catheter directed thrombolysis treated group, with no statistically significant difference between two groups ( P=0.692). The six month follow-up rate of PMT combined with catheter directed thrombolysis treated group was 71.05%(27/38), while that of the catheter directed thrombolysis treated group was 64.52% (20/31), with no statistically significant difierence between the two groups ( P=0.532). During the six month of follow-up, the recurrence rate of thrombus in PMT combined catheter directed thrombolysis treated group (3/27, 11.11%) was lower than those patients in catheter directed thrombolysis treated group (3/20, 15.00%), with no statistically significant difference between the two groups ( P=0.693). Conclusions:Compared with catheter directed thrombolysis treated group, PMT combined catheter directed thrombolysis treated group has a similar clinical efficacy for treatment of acute lower extremity deep venous thrombosis. PMT combined catheter directed thrombolysis treated group has advantages of reducing dosage of urokinase, shortening duration of thrombolysis time and relieving the swelling of suffered limb in a short time rather than catheter directed thrombolysis treated group. It shows a great result in the short term follow up.

ABSTRACT

Isolated resection of bemangioma in the cau-date lobe is challenging due to the surgical anatomy of caudate lobe. The caudate lobe consists three portions: Spiegel's lobe, paracaval portion and caudate process. Most of the blood supply of caudate lobe is provided by the posterior segmental branches of the portal vein and left hepatic artery. The hepatic venous drainage encompasses a few sizable and several small branches that join the inferior vena cava. Selection of the ideal route for bepatectomy, adequate mobilization of the liver, preparatory placement of band for hepatic vascular occlusion are key factors during the operation.

ABSTRACT

Objective To study the effect of flee radical on kidney repedusion injury caused by infra-renal abdominal aorta occlusion in rat model and its possible mechanism. Methods Forty-two healthy Wis-ter rats were randondy divided into 6 groups as following ( n = 7) : the control group( sham group) ; simply isehemia 5 h without reperfusion( group I) ; 2 hours reperfusinn following ischemia 5 h ( I/R 2 h), 4 honrs reperfusion following isebemia 5 h ( I/R 4 h), 8 hours reperfusinn following ischemia 5 h( I/R 8 h) and 12 hours reperfusion following ischemia 5 h ( I/R 12 h). In each group the rats were killed to obtain samples of blood and kidney at the specified time points. The contents of BUN, Cr, MDA, SOD in blood and in renal homogenate were measured in each group. We observed the morphological changes of kidney and muscles of lower limb by light microscope. Results BUN level of serum in model group I, I/R 2 h, I/R 4 h, I/R 12 h were higher obvionsly than those of control group, which were maximal in I/R 4 h, then decreased. MDA level of plasma in model group I, I/R 2 h, I/R 4 h, I/R 8 h, I/R 12 h groups were higher obvionsly than those of control group, which were maximal in I/R4 h group, then decreased. SOD level of plasma in model I/R 4 h, I/R 8 h groups were lower obviously than those of control group; SOD level of renal homogenate in model group I, I/R 2 h, I/R 8 h, I/R 12 h groups were higher obviously than those of group I/R 4 h, which were minimal in I/R 4 h group, then increased. By light microscope: The injury degree of kidney and muscles of lower limb in ischemia group was slight, the injury degree of repedusion group was severer than ischemia group. Conclusion The kidney repedusion injury caused by infrarenal abdominal aorta occlusion in rat model might be concerned with the increase of lipid peroxidatian damage after ischemia-repedusion in-jury of lower limbs.
