Objective To report deep venous thrombosis (DVT) after greater saphenous vein ligation and stripping and to evaluate diagnosis,treatment and prophylaxis. Methods The clinical characteristics, diagnosis and treatment of 12 inpatients with postoperative DVT were analyzed retrospectively. Results Of these 12 cases there were 7 cases of central type DVT,2 cases of peripheral DVT,and 3 cases of mixed type DVT.Secondary pulmonary embolism was complicated in 2 cases.Clinical symptoms in these 10 cases of proximal DVT were all severe.Catheter-directed thrombolysis(CDT) through the ipsilateral popliteal vein with protective(IV)CF was applied for these 10 cases.Of 10 cases,femoral vein was found ligated in 1 case,which was repaired under open surgery. Residual greater saphenous vein thrombus extending into deep vein was proved and managed by successful thrombolectomy in one case.Cockett syndrome were found as the causes in the other 8 cases,6 cases were treated with balloon dilatation angioplasty and endovascular stenting of the iliac vein.The 2 cases of with distal DVT were treated by anticoagulation therapy.All patients were cured. Conclusions Cockett syndrome,femoral vein injury and too long residual greater saphenous vein are common causes of DVT after greater saphenous vein ligation and tripping.Careful selection of cases,correct diagnosis,standard operative manipulation,early ambulation were all important in the prevention of DVT after great saphenous vein varix procedure.

Objective To compare the quality and preservation effect among the three models of pooled buffy coats (PBC) in pre-paring the platelet concentrate (PC) .Methods 63 identical ABO blood donations were randomly and averagely divided into three groups :the immediate PBC group(n=21) ,the buffy coats(BC) group(n=21) and the whole blood(WB) group(n=21) .In the im-mediate PBC group ,both the separation of the BC and the preparation of the PC was finished in the first day after collecting the WB;in the BC group ,the separation of BC was executed in the first day after collecting the WB ,while the preparation of the PC was completed in the second day ;in the WB group ,both the separation of the BC and the preparation of the PC was implement in the second day after collecting the WB .All the prepared PC were storage at (22 ± 2) ℃ for seven days in the preservation solution (composed by 2/3 PAS-ⅢM and 1/3 plasma) .Then compare the platelet(PLT) counts ,the red blood cell(RBC) residual quanti-ties ,the aggregative function of PLT ,the positive expression rates of CD62p ,the capability of hypotonic shock response(HSR) ,the PH value and the bacterial growth among PCs prepared by the three models during the stored time .Results Compared the immedi-ate PBC group during the seven stored days ,the PLT counts of the BC and WB groups were more ,the aggregative function of PLT in the BC group was better and the capability of HSR in the WB group was stronger ,but the other indexs between the immediate PBC group and the BC or WB group were no significant difference(P>0 .05) .Conclusion Both an overnight holding of BC and WB at room temperature models of PBC to prepare the PC are safe ,reliable and convenient ,and they could be substitute for the immedi-ate PBC model to prepare the PC .

Objective To assess the effect of anticoagulant drugs,elastic compression stockings(ECS)and(Daflon) on the prevetion of the post-thrombotic syndrome(PTS).Methods Fifty-eight deep venous(thrombosis)(DVT) patients were divided into control group and treatment group I and II.The control group (n=15) did not take anticoagulant drugs or the time of anticoagulant drug administration was less than 1 month,and the use of(ECS) was less than 3 months.The treatment group I(n=24) took warfarin for 6 months and the ECS were used in the follow-up time;the treatment group II(n=19),besides warfarin therapy and ECS,took Daflon for 12 months.All the patients were followed up,the general conditions were assessed with clinical score,and the therapeatic results of the 3 groups were assessed.Results The rate of PTS occurrence in control group was significantly higher than that in treatment group 1 and treatment group 2.At 6 months,the clinical score of treatment groups 1 and 2 was significantly lower than that of control group.At 1 and 1.5 years after discharge,the clinical score of treatment group 2 was significantly lower than that of treatment group 1.Conclusions The long-term comprehensive and systemic therapy(including warfarin,ECS and daflon) for DVT could prevent PTS.

Objective To investigate the diagnostic value of multiplanar reformation (MPR)reconstruction for the detection of traumatic diaphragmatic rupture (TDR) in multi-slice CT examination.Methods Thirty six cases with thoracoabdominal trauma, including 21 cases with and 15 cases without TDR confirmed by surgery, received multi-slice CT examination. They were enrolled in this study. Three experienced radiologists retrospectively analyzed the axial and MPR images. The diagnostic criteria for TDR included abnormally elevated hemidiaphragm, diaphragmatic discontinuity, the "collar sign" or "dependent viscera "sign. Referenced to surgical results, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of axial and MPR images in detection of TDR were calculated. The McNemar was used to investigate the differences between axial and MPR images in the detection of diaphragmatic discontinuity and "collar sign", and the differences between axial and MPR images of these two signs in TDR diagnosis. Results The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of axial images in detection of TDR were 71% ( 15/21 ), 80% ( 12/15 ), 83% ( 15/18 ),67% ( 12/18 ) and 75% ( 27/36 ), respectively; of MPR images, they were 86% ( 18/21 ), 93%(14/15), 95% ( 18/19 ), 82% ( 14/17 ) and 89% ( 32/36), respectively. By axial images, twelve diaphragmatic defects or interrupts were identified in nine cases, and "collar sign" was identified in six cases. By MPR, 20 diaphragmatic defects or interrupts were identified in 15 cases ( P = 0.125 ), and "collar sign" was identified in 14 cases (P =0.021 ). The sensitivity and specificity of diaphragmatic defects or interrupts for TDR diagnosis in axial images were 43% (9/21) and 80% ( 12/15 ), respectively;in MPRimages, they were71% (15/21) (P=0.125)and93% (14/15) (P=0.500), respectively.The sensitivity and specificity of "collar sign" for TDR diagnosis in axial images were 29% (6/21) and 100% ( 15/15), respectively; in MPR images, they were 67% ( 14/21 ) (P =0. 021 ) and 100% (15/15)( P = 1.000), respectively. Conclusions MSCT presented good sensitivity, specificity and accuracy for the diagnosis of TDR. MPR images were useful supplements for axial images in TDR diagnosis which improved the diagnosis.

Objective To evaluate the endovascular treatment of diffuse aortoiliac occlusive diseases. Methods Thirty-two patients underwent endovascular treatment in which rest pain was found in 84.38%, foot local gangrene in 15.62%. Mean age was 69.7 years (range, 52 years to 81 years) and 71.9% was male. Trans Atlantic Inter-Society Consensus C and D disease was respectively in 40.6% and 59.4% patients. Mean length of vasculopathy was (14.6 ± 1.2) cm (range, 4.5 cm to 19.5 cm) All patients had prohibitive risk for open revascularization. With the approach from femoral artery or brachial artery, combined techniques, such as recanahzation, balloon dilation, stent placement and concomitant common femoral endarterectomy were used. Results Technical success was achieved in twenty-nine patients(90.63%). The complication rate was 3.45%. Clinical status was markedly improved in eight cases (27.59%) and moderately improved in twenty-one cases(72.41%). Mean postoperative ABI was 0.73 ± 0.12, mean preoperative ABI was 0.32 ± 0.09. Significant differences were seen between postoperative ABI and preoperative ABI(P<0.05). Mean time of follow-up was (13.9±6.2) months. At 6 months, primary patency was 81.82% and secondary patency was 89.09%. At 12 months, primary patency was 63.64% and secondary patency was 80.18%. Conclusion Combined multiple endovascular technique is a safe and effective method in the treatment of poor risk diffuse aortoiliac occlusive diseases.

Objective To explore the preliminary results of application of reserving the left subclavian artery by fenestration of domestic stent graft in the thoracic endovascular aortic repair (TEVAR) of type B dissection with unfavourable proximal landing zone.Methods From October 2015 to January 2018,a total of 13 patients with type B aortic dissection without healthy proximal landing zones underwent TEVAR using fenestration of domestic stent graft in our hospital.Computed tomography angiography (CTA) data were measured before surgery.Digital subtraction angiography (DSA) was conducted after surgery.All patients underwent CTA or ultrasound examination during follow-up.Operation success rate,survive rate,patency of left subclavian artery and complications were analyzed.Results All the patients were deployed fenestrated endografts successfully.No proximal endoleak happened during perioperative period.Delirium occurred in 1 case during 7 postoperative days and fully recovered with the medical treatment.The mean follow-up period was (9.8 ± 9.5) months (range,1-29 months).11 patients underwent CTA and 2 patients underwent ultrasound examination during follow-up.During period of following up,no patients died,no proximal endoleak appeared,and all the left subclavian arteries reserving by fenestration.Conclusions Reserving the left subclavian artery by fenestration of domestic stent graft in TEVAR of type B dissection with hostile proximal sealing zone is economical,safe and feasible,which expand the indication of TEVAR for aortic dissection,and the long-term outcomes of this technique need to be assessed in the future.

Objective To analyse the initial resucts in different treatment methods for the treatment of aortic arch injury.Methods A total of 23 patients (18 males and 5 females) with injuries of superior arch arteries underwent our treatment in Shandong Provincial Hospital Affiliated to Shandong University from January 2008 to May 2017.Nine patients underwent surgical procedures(surgical group),13 patients underwent endovascular procedures (endovascular group),1 patient underwent conservative treatment.The conditions of all survived patients were followed up by telephone or outpatient from one to sixty months postoperative.Mortality and complications such as rehaemorrhagia,cerebralinfarction,stenosis or blockage during the follow-up period was assessed.Operation time,hospitalization time after treatment,mortality and complications within 30 days of surgical group and endovascular group were compared by statistical methods.The data were analyzed by SPSS 16.0 software.Measurement data were expressed as ((x) ± s).The count data were expressed as frequency and percentage (％),and comparison between groups were evaluated with t test,Chi-square.Results All patients had achieved technical success.In patients treated by surgical procedures,one case of death and 2 cases of cerebralinfarction were reported within 30 days.One patient died of rehaemorrhagia during the 2nd day of open operation.Meanwhile,another two patients suffered from cerebral infarction,they recovered within 30 days.All patients treated by endovascular procedures survived without cerebralinfarction.However,blockage occurred in one patient of these patients.The operation time [(2.4 ± 1.1) hours and (1.0 ± 0.4) hours] (P ＜ 0.01) and the time of postoperative hospitalization [(8.3 ± 3.0) days and(2.5 ± 1.0) days] (P ＜ 0.05) were statistically different of the two groups.The postoperative mortality rate of the two groups undergoing open surgery and endovascular treatment within 30 days was 11.1％ and 0.0％ (P =0.41),and complication rates with 33.3％ and 7.7％ respectively (P =0.26),there has no significant difference.Overall,66.7％ (6/9) patients treated by surgical procedures and 92.3％ (12/13) patients treated by endovascular procedures and one patient treated by consewative treatment survived without any complication during the follow up period.Conclusions Initial results suggest that endovascular procedures can significantly shorten the time of operation and the time of postoperative hospitalization,and the mortality and complication rate are also slightly lower than surgical procedures.Endovascular procedures is an important method for treatment for injuries that involve superior arch arteries.It plays a special role in rescuing injuries of superior arch arteries.

OBJECTIVE: To analyze the clinical and genetic features of a patient with Treacher Collins syndrome (TCS), and identify the mutation in TCOF1 gene. METHOD: The medical history was taken, and general physical examinations and otological examinations were conducted in this patient. Genomic DNA was extracted from this patient and his parents and complete TCOF1 gene coding exons were amplified by specific PCR primers. Direct sequencing was carried out to identify the mutations. The raw data was analyzed with GeneTool software and molecular biological website. RESULT: We detected a heterozygous c. 1639 delAG mutation in exon 11 of TCOF1, which resulted in a truncated protein lacking normal function. This mutation is a novel mutation and the second case identified in exon 11 of in TCS. CONCLUSION TCS patient reported in this study has unique clinical phenotype. TCOF1 gene mutation is the specific risk factor.
