ABSTRACT
Myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) associated vasculitis is an autoimmune disease usually with severe multiple dysfunction syndrome, especially prominent acute renal failure. A 65-year-old woman was admitted with progressive dyspnoea for six months and fever, sputum with blood, pain of the lower extremities and intermittent claudication for two days, indicating multiple organ involvement (respiratory system, blood vessels). The renal involvement was relatively mild, presenting with microscopic haematuria. The chest computed tomography demonstrated multiple pulmonary embolisms. Ultrasound and computed tomography angiography for the lower extremity vessels showed venous and arterial thrombosis. Exclusion of other diseases that can cause multiple organ damage and thrombosis, the positive perinuclear ANCA and MPO-ANCA strongly support the diagnosis of MPO-ANAC-associated vasculitis. The patient's physical condition has been greatly improved by treatment with corticosteroids and anticoagulation.

Objective To analyze the clinical efficacy of transcatheter hepatic arterial thrombolysis combined with splenic arterial embolization in the treatment of hepatic artery thrombosis (HAT) after liver transplantation. Methods Clinical data of 9 patients diagnosed with HAT after liver transplantation undergoing transcatheter hepatic arterial thrombolysis combined with splenic arterial embolization were retrospectively analyzed. The incidence of HAT and clinical efficacy of thrombolytic therapy were summarized. The incidence of thrombolysis related complications and clinical prognosis were evaluated. The thrombolytic therapy procedures of typical cases were analyzed. Results HAT was diagnosed at 1-66 d after liver transplantation with a median time of 10 d. The formation site of HAT was found at the anastomosis of the main hepatic artery in 8 cases and at the right branch in 1 case. Upon diagnosis, 9 patients received transcatheter hepatic arterial thrombolysis combined with splenic arterial embolization in emergency. The hepatic artery was open during operation in 4 cases and treated with postoperative thrombolytic therapy with indwelling catheter in 3 cases. The opening time for inwelling catheter was 72-96 h. The total successful rate was 7/9. The thrombolysis related complication of abdominal hemorrhage occurred in 1 case after surgery. Three cases died, including 2 cases of liver failure and infection, and 1 case of biliary ischemia and systemic infection at 70 d after interventional therapy. Conclusions Hepatic arterial thrombolysis combined with splenic arterial embolization is an efficacious treatment for HAT after liver transplantation, which can serve as the optimal therapy for patients who are unable to undergo secondary liver transplantation.
ABSTRACT
Objective Through the analysis of cases,to improve the cognition of clinicians on extracranial vas-cular embolism diseases(VED)in children.Methods The clinical information included incidence trend,thrombophi-lia,clinical features,treatment and prognosis of 29 children with VED,who were admitted from January 201 1 to Decem-ber 201 5 in Nanjing Children′s Hospital Affiliated to Nanjing Medical University,and retrospectively analyzed.Results The annual rate of VED increased from 0 to 1 .49 per 1 0 000 hospital admissions from January 201 1 to December 201 5.In 29 cases,there were 20 male and 9 female,with an average age of 6.03 years old (2 h -1 3.83 years old).In-fants accounted for >20%(6 /29 cases).The average age of the female,non infected group,rheumatic disease group and venous thrombosis group was higher than that of the male,the infection group,the non rheumatic disease group and the arterial embolization group,but there was no significant difference(all P >0.05).Thrombophilia were as follows:in-fection disease,heart disease,kidney disease syndrome,rheumatoid disease,tumor,and twins embolization syndrome. Risk factors included central venous line,immobility,dehydration,glucocorticoids use,etc.Heart disease was the leading cause of non thrombotic embolism,while other thrombophilic diseases resulted in thrombotic embolism.Pulmonary em-bolism was mainly seen in patients with severe pneumonia,especially mycoplasma pneumoniae pneumonia (MPP ).The older the age,the more typical clinical manifestations,and significantly elevated D dimer,fibrin/fibrinogen degradation products tips VED.Treatment depends on the degree of risk.Thirty -seven point five percent(3 /8 cases)of children with arterial embolism were less than 1 year old,and the mortality 25.00% (2 /8 cases)was significantly higher than that of venous thrombosis 1 7.65%(3 /1 7 cases)and 1 1 .76% (2 /1 7 cases).Conclusion Heart disease mainly cause arterial embolism and infection,while nephritic syndrome and rheumatic disease mainly cause venous embolism.Pulmona-ry embolism is mainly seen in children with severe pneumonia,especially MPP.The risk of arterial embolization is higher than that of venous embolism.
ABSTRACT
Many complications have been reported during or after anterior cruciate ligament (ACL) reconstruction, including infection, bleeding, tibial tunnel widening, arthrofibrosis, and graft failure. However, arterial injury has been rarely reported. This paper reports a case of an anterior tibial arterial injury during bicortical tibial drilling in arthroscopic ACL reconstruction, associated with an asymptomatic occlusion of the popliteal artery. The patient had a vague pain which led to delayed diagnosis of compartment syndrome and delayed treatment with fasciotomy. All surgeons should be aware of these rare but critical complications because the results may be disastrous like muscle necrosis as in this case.

ABSTRACT
Objective To present and summarize the data concerning the treatment and prognosis of acute limb arterial embolism in West China Hospital.Methods Forty three patients with 52 limbs of acute arterial embolism were treated in West China Hospital from January 2003 to March 2006.There were 15 males and 28 females,aging from 26 years to 77 years 〔(58.88?13.90) years〕.The diagnosis was based on clinical manifestations and results of color Doppler sonography or DSA.The follow-up ranged from 1 month to 39 months.The following factors,which might influence the prognosis,were analysed through multiple linear regression of SPSS 10.0:age,sex,uper limb or lower limb,location of embolus,ischemic time,clinical categories of acute limb ischemia,history of smoking,atherosclerosis and other combined diseases,pervious history of acute limb arterial embolism,operative or nonoperative treatment,and postoperative complications.Results Clinical categories of acute limb ischemia include:Ⅰ(n=0),Ⅱa(n=16),Ⅱb(n=29),Ⅲ(n=7).The ischemic time varied from 3 h to 2 weeks.The sources of embolus:heart(n=39),vessle(n=7),iatrogenic origin(n=1),unidentidied origin(n=5).The therapies included embolectomy(n=38),catheter-directed thrombolysis(n=2) and medical treatment(n=12).The following postoperative complications occured:compartment syndrome(n=12),respiratory failure(n=3),alkalolsis(n=3),acute renal failure(n=2),wound infection(n=2) and pulmonary infection(n=1).Two patients died of cerebral infarction in hospital and one patient died of heart failure 3 months after discharge.Thirty-eight patients with 45 diseased limbs were followed up.The results were excellent in 13 limbs,good in 15 ones,fair in 8 ones and poor in 9 ones.The statistically significant influencing factors of prognosis include ischemic time,clinical categories of acute limb ischemia and history of smoking(P
ABSTRACT
The study involved 44 patients (22 males, 18 females, aged from 33 to 94 years) with acute ischemia of extremities due to peripheral arterial embolism, who were undergoing surgery for removing clots at ViÖt - §øc Hospital from January 1998 to December 2001. Results: the common clinical signs included the lack of pulse, cold extremities; loss sense and movement were advanced signs. Rate of amputation was high. 5 cases were given preoperative anticoagulation. One had to be amputated. 2 cases were received conservative management with fasiotomy. 2 cases were fail to angioplasty because of necrosis. Maintaining postoperative anticoagulation improved the chance of full extremity repairing prevented from recurrence, especially when the embolism was resolved

Objective To evaluate the effects(mortality, amputation rate, the length and expense of hospital stay, etc)of the obstructing blood flow interventional embolectomy and simple interventional embolectomy for acute lower limb arterial embolism. Methods 79 cases of acute lower limb arterial embolism including 23 cases of two sites puncturing and obstructing blood flow interventional embolectomy and 56 cases treated by simple interventional embolectomy were retrospeetively analyzed and compared. Results Embolisms were removed in all 79 cases and arteries were reopened successfully. The mortality and the amputation rates of the simple and the obstructing blood flow embolectomies were 5.36%,19.6%, and 4.35%, 8.70% respectively. Conclusion Two sites puncturing and obstructing blood flow interventional embolectomy for acute lower limb arterial embolism is simple, safe and effective, comparing with the simple interventional embolectomy, with lower amputation rate, quicker recovery and lower expense, however with no statistical significance in mortalities.
ABSTRACT
Objective To assess the feasibility and efficacy of catheter-directed thrombolysis with recombinant tissue plasminogen activator(rt-PA)for acute limb embolism in patients with recent cerebral embolism.Methods Eight patients with atrial fibrillation history happened to suffer acute limb embolism after recent cerebral embolism.The affected arteries included 2 left common iliac arteries,4 femoral arteries(3 left,1 right),2 right popliteal arteries.Catheter-directed thrombolysis with rt-PA was applied with bolus administration plus continuous perfusion.Percutanous transluminal angioplasty with balloon dilatation was applied in 3 patients,and one stent placement in one patient.Results The mean duration of continous perfusion was 3.6 hours and the mean dose of rt-PA administered was 23.6 mg(range,20 ～ 28 mg)with complete recanalization rate of 100%.Clinical complete relief rate was 7/8 with one patient suffering from rest pain due to distal occlusion of anterior/posterior tibial artery.The complications included hematoma at puncture site(6/8),bleeding around the vascular sheath(2/8)and hematuria(1/8).No intracerebral hemorrhage was found on CT scans after the thrombolysis.During follow up of 3-6 months,no recurrent embolism or thrombosis occurred in the limbs except one patient with recurrent cerebral embolism and died.Conclusions Catheter-directed thrombolysis with rt-PA is probably to be a safe and effective method for acute limb embolism in patients with recent cerebral embolism and atrial fibrillation history.
ABSTRACT
Thoracic outlet syndrome (TOS) is an uncommon condition which is caused by compression of subclavian artery, vein or brachial plexus in the region of thoracic outlet area, which is composed by the first rib, clavicle, anterior and middle scalene muscles and other connective tissue. In arterial TOS, chronic arterial compression causes arterial stenosis, poststenotic dilatation, aneurysm formation, intramural thrombus and peripheral arterial embolism. We present herein a case of arterial TOS patient with multiple distal embolization. The patient was 43-year old male with crutch ambulation because of sequelae of polioviral infection in his youth. His chief complaint was discoloration and gangrenous change of five right digits for 1 month. A rudimentary first right rib was found in simple chest X-ray. Angiographic findings were stenosis and poststenotic dilatation of right subclavian artery, multiple peripheral arterial embolic obstructions and numerous collateral vessel formation. Right thoracoscopic sympathectomy (T2), resection of the abnormal first rib and the abnormal axillary arterial segment was performed through the supraclavicular and transaxillary incision, then interpositional graft with saphenous vein was done for arterial reconstruction. A minor lymphatic fluid collection around the area of operation occurred, but it was easily controlled by percutaneous drainage. The gangrenous wounds of digits were improved after restoration of blood circulation.
