ObjectiveTo investigate clinical features,diagnosis and treatment of hyperlipidemic severe acute pancreatitis(HSAP) in late pregnancy. MethodsA retrospective analysis was made on 12 HSAP cases. ResultsHSAP accounting for 20%(12/60) of severe acute pancreatitis (SAP) cases, develops during the period of 28~36 weeks of pregnancy. There were 5 cases in SAP type Ⅰand 7 cases in SAP type Ⅱ. Multiple organ dysfunction syndrome (MODS) was complicated in 4 cases. HSAP is featured with severe hypertriglyceridemia (29?14)mmol/L, significant systemic inflammatory response syndrome (SIRS), large amount of lipidemic bloody ascites. All cases underwent successful. Cesarean section followed by pancreatic operation and were cured. ConclusionHSAP in late pregnancy is a specific type of SAP with fulminant clinical course leading to fetal distress. Effective management of pregnant hypertriglyceridemia helps to prevent HSAP.

Objective To investigate the management of acute limb ischemia.Methods The clinical data of 28 patients with acute limb ischemia were retrospectively analyzed.Four patients with arterial embolism underwent embolectomy.one patient with pseudoaneurysm underwent false aneurysm resection and revascularization with PTFE,23 patieuts wiht arterial occlusive disease were treated by multiple means such as embolectomy,bypass,primary amputation,endovascular interventions,and pharmacologic therapy(n=23).Results The 5 patients with arterial embolism or pseudoaneurysm were all treated successfully.In the 23 patients with arterial occlusive disease,5(21.7%) were treated successfully,12(52.2%) were improved,and 6(26.1%) had ineffective treatment.No inpatient died,but 4 patients underwent amputation.During follow-up of 6-45 months,there were 4 deaths and other 5 amputations.Conclusions Proper intervention of patients with acute limb ischemia should be chosen according to clinical evaluation of the illness,and includes embolectomy and revascularization,to get limb or life salvage.

ObjectiveTo study the treament of arterial occlusion of lower extrimities. MethodsSeventy-three cases(78 limbs) of chronic ischemia o f lower extremities were diagnosed as artroial occlusion by color u ltrasounography, DSA or MRA. Arterial bypass using grafting,endarterectomy and percuteneous transluminal angioplasty (PTA) were used for the artery segmental occlusion in 44 limbs. Venous arterialization and reconstruc tion of profunda femoris were performed for extensive occlusion in 29 limbs. ResultsAll the cases showed satisfactory r esults 6 months to 8 years after operation except 8 limbs (segmenta l occlusion in 3 limbs and extensive occlusion in 5 limbs) were amputated. ConclusionsThe key points of improvement of the therapeu tic effects of the arteral occlusion of lowe extremity lie on the cho ice of the therapeutic methods accoding to the results of DSA or MRA.

Objective To evaluate pigtail catheter mashing thrombosis combined with catheter directed thrombolysis in the treatment of acute iliofemoral venous thrombosis complicated by Cockett syndrome in the left lower limbs.Method Data of 137 cases of acute iliofemoral venous thrombosis complicated with Cockett syndrome in left lower limb by interventional therapy from January 2007 to October 2012 were analyzed retrospectively.Inferior vena cava filters were placed in all of the patients.Patients were divided into two groups:Group A (n =81) treated with catheter directed thrombolysis only,Group B (n =56) treated with pigtail catheter mashing thrombosis combined with catheter directed thrombolysis.After operation,patients were treated by anticoagulation with urokinase and heparin calcium,and then warfarin for 6 to 1 2 months.Results The thrombolysis time in group B was significantly shorter than that in group A (P ＜0.01),the dosage of urokinase was significantly less than that in group A(P ＜ 0.01).The venous patency score in group B after therapy was significantly better than in group A (P ＜ 0.01).121 patients were followed up for 10-60 months.There were no pulmonary embolism.Conclusions Pigtail catheter mashing thrombosis combined with catheter directed thrombolysis in the treatment of acute iliofemoral venous thrombosis complicated with Cockett syndrome in left lower limb can improve thrombolytic efficiency,shorten thrombolysis time,reduce the use of urokinase.

Objective:To investigate the feasibility and clinical value of endovascular treatment of iliac vein disease via the great saphenous vein approach.Methods:Eighty-six patients with nonthrombotic left iliac vein compression lesions identified by anterograde lower limb vein angiography were divided into 2 groups: group A ( n=46) was treated via great saphenous vein and group B ( n=40) was treated via femoral vein. The success rate of puncture, time consuming of puncture catheterization, postoperative bed immobilization and complication rate of puncture were observed and compared between the two groups. Results:The puncture success rate was 97.8% (45/46) in group A and 100% (40/40) in group B, there was no significant difference between the two groups（ P>0.05）. The average puncture time was (9.4±2.7) min in group A and (5.5±1.3) min in group B ( P<0.05). The complication rate of group A was lower than that in group B ( P<0.05). The patency rate of iliac vein stent was 100%, as indicated by venous color ultrasound or angiography. Conclusion:Endovascular treatment of iliac vein disease via great saphenous vein approach is a safe and feasible method with less trauma and easier postoperative care.

Objective:To evaluate the technical aspects and examine patency rates of stent placement across the inguinal ligament for managing long-segment iliac venous obstruction.Methods:From Jan 2012 to Jan 2017, a total of 73 patients (42 cases of post-acute deep venous thrombosis(DVT) thrombolysis and 31 of post-thrombotic syndrome (PTS)) with long-segment iliac venous obstruction were treated with interventional surgery. All patients underwent balloon dilatation and placement of at least two stents extending below inguinal ligament.Results:The technical success rate was 100%. No serious perioperative complications occurred. The mean duration of the procedure in the DVT group was shorter than PTS group(35±12) min vs. (62±12) min, P<0.05). The mean number of stents did not differ between the two groups.Mean follow up periods was 28.34 months. Overall cumulative primary, assisted primary, and secondary stent patency rates were 100%, 100%, and 100% at 6 months and 87.7%, 95.9%, and 100% at 12 months and 75.8%, 85.1%, and 96.3% at 24 months, respectively(all P>0.05). Edema and pain alleviated significantly in the two groups. There was no stents compressed or fractured. Conclusions:Stenting across the inguinal ligament for treatment of long-segment iliac venous obstruction is a safe, effective, and feasible method.
