ABSTRACT

Objective:To investigate the significance of filtration fraction (FF) and renal artery stenting in the treatment of atherosclerotic renal artery stenosis.Methods:In the study,42 cases of renal artery stenosis were treated with 52 renal artery stent implantation.Percutaneous transluminal renal angioplasty and stent (PTRAS) of the patients' health side kidney,ipsilateral kidney (renal) glomerular filtration rate (GFR),renal effective renal plasma flow effective renal plasma flow (ERPF),kidney filtration fraction changes of preoperative and postoperative serum creatinine (SCR) and the changes in the patients with blood pressure (SBP) and the changes after taking antihypertensive drugs were observed and analyzed.Results:The 52 cases of renal artery stent implantation were all successful.Preoperative ipsilateral GFR was significantly lower than that of normal side (t =-3.989,P =0.000);preoperative ipsilateral ERPF was significantly lower than the contralateral side (t =-4.926,P =0.000).On both sides,the overall FF values were equal (t =1.273,P =O.207).Postoperative ipsilateral renal GFR was increased,but there was no statistical difference (t =-1.411,P =0.164).Postoperative ipsilateral renal ERPF was increased significantly (t =-4.954,P =0.000),and FF lower (closer to the normal value (t =3.274,P =0.002).Postoperative side GFR was significantly reduced (t =2.569,P =0.000),the contralateral ERPF was significantly reduced (t =3.889,P =0.001),and FF had no significant change (t =-0.758,P =0.454).Postoperative side GFR was lower than that of the contralateral (t =-3.283,P =0.002) and postoperative side ERPF was still lower than that of the contralateral (t =-3.351,P =0.001),but on both sides,the FF values were equal (t =-0.361,P =0.719).Preoperative FF was relatively normal in the patients with kidney,and the postoperative FF value change was small (t =O.799,P =O.430);preoperative FF was significantly higher in the patients with kidney,and the postoperative FF value was lower than the preoperative (normal value,t =5.299,P =0.000).Postoperative overall serum creatinine was significantly decreased (t =2.505,P =0.016);but for the patients with unilateral renal artery stenosis,the changes in serum creatinine had no statistical difference (t =1.228,P =0.299);and for the patients with bilateral renal artery stenosis and serum creatinine compared with the preoperative,the changes were decreased significantly (t =2.518,P =0.030);postoperative blood pressure (SBP) was significantly decreased compared with that before operation (t =8.945,P =0.000);antihypertensive drugs taken were decreased significantly compared with the preoperative (t =5.280,P =0.000).Conclusion:For the patients with renal artery stenosis,FF is a useful index to understand the pathophysiological process of renal ischemia.Whether preoperative FF is significantly increased or FF is relatively normal,should be regarded as the indications of renal artery stent implantation.

ABSTRACT

Objective:To evaluate the effectiveness and safety of endovascular treatment in solving symptomatic cerebral artery tandem lesions.Methods:From June 201 2 to February 201 4,1 2 cases (24 lesions)with symptomatic cerebral artery tandem lesions were accepted for the endovascular treatment. The distributions of the tandem lesions were as follows:the common carotid artery and internal carotid ar-tery (1 case),the internal carotid artery and the proximal of the carotid cavernous sinus segment (3 ca-ses),the internal carotid artery and the distal of the carotid cavernous sinus segment (4 cases),the in-tracranial segment of internal carotid artery and middle cerebral artery M1 segment (2 cases),the first segment of vertebral artery and intracranial segment of vertebral artery (2 cases).All of these cases were treated from distal lesions to proximal lesions except for tandem lesions in the internal carotid artery and the distal of the carotid cavernous sinus segment in order to obtain better support.Tandem lesions were treated in the same operation with local anesthesia or general anesthesia.The procedures of the 1 2 cases retrospectively were analyzed and the peri-operation complications and responsibility region recurrent is-chemic stroke incidents observed.Results:All tandem lesions were solved successfully all at once.There were no peri-operation complications or recurrent ischemic stroke incidents.There were no recurrent is-chemic stroke incidents or stent restenosis cases in the follow-up.Conclusion:It is safe and effective for selective endovascular treatment in solving symptomatic cerebral artery tandem lesions at the same time, but we should take careful preoperative evaluation and improve the operation plan.

ABSTRACT

Objective:To study the clinical effects of percutaneous transluminal angioplasty (PTA ) versus stent implantation (ST)after PTA for the treatment of femoral and popliteal artery lesion resulted from arteriosclerosis obliterans.Methods:One hundred and three patients (1 1 9 limbs)treated for femo-ral and popliteal artery lesion resulted from arteriosclerosis obliterans for ten years were reviewed,of whom 60 limbs were treated by PTA and the other 47 by PTA combined with stent implantation.Results:Among the 60 limbs of the PTA group,there were 22 limbs involved only in femoral and popliteal artery;1 3 limbs combined with iliac artery lesion;1 7 limbs combined with infrapopliteal artery lesion;8 limbs combined with iliac and infrapopliteal artery lesion.Among the 47 limbs of the ST group,there were 1 8 limbs involved only in femoral and popliteal artery;8 limbs combined with iliac artery lesion;1 5 limbs combined with infrapopliteal artery lesion;6 limbs combined with iliac and infrapopliteal artery lesion. There was no significant difference between the two groups on age,sex,concomitant disease,ankle bra-chial index(ABI)before treatment and Rutherford classification (P>0.05).The patients’Trans-atlantic inter-society consensus (TASC)C/D was lower in the PTA group than that in the ST group (58.3%vs. 76.6%,P=0.047).The follow-up periods were 48.0 (5.0,1 08.0)and 40.0 (3.0,96.0)months respectively (P=0.064).Compared with the PTA group,the ST group had a better short-term total effective rate (93.6% vs.80.0%,P=0.044)and a higher cost [(33 882.7 ±8 695.6)yuan vs. (1 7 754.8 ±3 654.2)yuan,P<0.001 ].The short-term marked effective rate of the ST group was higher than that of the PTA group,but the difference was not significant (31 .9% vs.21 .7%,P =0.231 ).There was no significant difference between the two groups on short-term efficiency,and compli-cation rates (58.3%vs.58.3%,P=0.724;1 .7%vs.2.1%,P=1 .000).There was no death during perioperative period and no short-term deterioration in both the groups.The long-term marked effective rate was lower and the deterioration rate was higher in the ST group than that in the PTA group,but the difference was not significant (8.5% vs.1 5.0%,P=0.381;1 4.9% vs.5.0%,P=0.081 ).There was no significant difference between the two group on long term total effective rate,accumulative limb salvage rate and reoperation rate (66.0% vs.66.7%,P=0.939;94.7% vs.94.1%,P=0.884;31 .9% vs.31 .7%,P=1 .000),and the 1 to 1 0 years primary and secondary patency rates were similar (P=0.837,P=0.622).When compared based on TASC classification,TASC A/B patients in the ST group had a higher short-term marked effective rate,a higher short-term total effective rate and a higher long-term deterioration rate than those in the PTA group,but the difference was not significant (36.4%vs.24.0%,P=0.353;1 00.0%vs.88.0%,P=0.322;1 8.2%vs.4.0%,P=0.21 6).TASC C/D patients had a similar result (30.6%vs.20.0%,P=0.307;91 .7%vs.74.3%,P=0.050;1 3.9%vs.5.7%,P=0.226).Both TASC A/B and TASC C/D patients in the ST group had a similar accumu-lative limb salvage rate with that in the PTA group (90.9% vs.90.6%,P =0.920;97.1% vs. 94.1%,P=0.796).Conclusion:Stent implantation can increase the cost and short term effective rate at the same time and is not superior to PTA on the long term effective rate and limb salvage rate for femo-ral and popliteal artery lesion resulted from arteriosclerosis obliterans.

ABSTRACT

Objective:To anslysis the hemodynamic states of vertebrobasilar dolichoectasia based on computational fluid dynamics technique.Methods:The original DICOM format image data from a patient with vertebrobasilar dolichoectasia (VBD), were imported by the Mimics software directly,and the 3D Objects were constructed.The simulation of model was made with Ansys software, the hemodynamic pa-rameters such as streamlines, wall shear stress( WSS) and wall pressure were described.Results:There was stable laminar flow in proximal basilar artery and was no blood flow mixed by bilateral vertebral arter-y.However, Spiral flows were appeared in distal tortuous basilar artery.The low WSS regions in the ver-tebra-basilar junction section and inferior segment of basilar artery were coincide with the high wall pres-sure regions.It could be speculated the initial growth regions might be located in the vertebra-basilar junction section and inferior segment of basilar artery.Local regions with low WSS and high wall pressure might be associated with the occurrence and development of VBD.Conclusion: CFD numerical simula-tion maybe can provide a theoretical basis for the role of hemodynamic factors in occurrence and develop-ment of VBD.

ABSTRACT

Objective:To study the clinical effects of endovascular reconstruction versus bypass surgery for TASC Ⅱ( trans-atlantic inter-society consensus Ⅱ) C/D femoropopliteal artery lesion resulted from arteriosclerosis obliterans. Methods:One hundred and three patients(119 limbs) accepted bypass surgery or endovascular therapy for TASCⅡC/D femoropopliteal artery lesion between January 2002 and Decem-ber 2012 at our institution were retrospectively assessed. All the patients were diagnosed with arterioscle-rosis obliterins, and all their Rutherford classifications were from 2 to 5 degrees. Among them there were 71 limbs treated by endovascular reconstruction and the other 48 limbs were treated with bypass surgery. We evaluated the short term clinical effect according to the condition when patients left the hospital, and evaluated the long term clinical effect according to the results of the patients' latest follow-up in 2014. Their clinical data before treatment, complication rates, death rates, hospital stays, short term and long term effects, reoperation rates, 1 to 10 years primary and secondary accumulative patency rates and limb salvage rates were compared. Results:There was no significant difference between the bypass group and the endovascular group on the mean age and ankle brachial index before treatment [(67. 1 ± 7. 1) years (51 to 80 years) vs. (68. 0 ± 9. 4) years (49 to 91 years),P=0. 561;(0. 41 ± 0. 23) vs. (0. 40 ± 0 . 26 ) , P=0 . 928 ] . There were more TASCⅡD patients in the bypass group than those in the endovas-cular group ( P<0 . 001 ) , and the rutherford classification was higher in the endovascular group than that in the bypass group. The difference in the mean follow-up between the bypass group and the endovascular group was not significant[(41. 7 ± 23. 6) months vs. (59. 5 ± 41. 6) months,P =0. 065]. Five peri-operative complication cases occurred in the bypass group, including 2 cases of acute thrombosis,1 case of infection and 2 cases of heart failure, and only 1 complication case occurred in the endovascular group that was heart failure. The complication rate was higher in the bypass group than that in the endovascular group [10. 4% vs. 1. 4%, P=0. 039]. And there was no death in both the groups. Compared with the endovascular group, the bypass group had a longer hospital stays [(13. 2 ± 4. 7) d vs. (6. 5 ± 3. 1) d, P<0. 001],a higher reoperation rate (58. 3% vs. 31. 0%,P =0. 003), a better short term, obvious, and effective rate (25. 0% vs. 9. 9%, P =0. 027),a worse long term deterioration rate (37. 5% vs. 18. 3%,P=0. 019) and higher 1 to 10 years primary and secondary accumulative patency rates( P =0 . 001 , P=0 . 001 ) . There was no significant difference between the two groups on the increase of ankle brachial index[(0. 34 ± 0. 28) vs. (0. 31 ± 0. 23), P=0. 371], and short term and long term total ef-fective rates (89. 6% vs. 84. 5%, P=0. 426;45. 8% vs. 56. 3%, P=0. 260), and limb salvage rate (83. 3% vs. 94. 4%,P =0. 051). Conclusion:Endovascular therapy is a safe, effective and minimally invasive therapy for TASCⅡ C/D femoropopliteal artery lesion resulted from arteriosclerosis obliterans.

ABSTRACT

Objective To study the clinical characteristics and treatment strategy for isolated dissection of the superior mesenteric artery (SMA).Methods Clinical data of 19 consecutive patients with IDSMA were retrospectively analyzed.There were 15 men and 4 women.The mean age was 56 ± 12 (41-84) years old.Fifteen patients presented with abdominal pain and 4 patients had no symptom.The dissections were diagnosed by contrast-enhanced computed tomography in 18 patients and ultrasonography in 1 patient.Results The dissections were located at the anterior wall of the curvature part of the SMA in all 19 patients.Asymptomatic patients underwent conservative management.One asymptomatic patient with aneurysmal dilation was managed by stent and the 15 symptomatic patients underwent endovascular management.During the mean 7-46 (21 ± 10) months follow-up period,all patients were asymptomatic with patency of SMA.Conclusions The dissection was located at the anterior wall of the curvature part of the SMA.Conservative management can be applied to the asymptomatic patients.For symptomatic patients without intestinal necrosis or artery rupture,stent implantation is recommended,and the curvature of SMA should be covered completely.Endovascular spasmolysis is helpful in relieving pain.

ABSTRACT

Objective To evaluate the technique of selective portal vein embolization before hepatectomy and its value in the preparation of major hepatic resection for those with insufficient future remnant liver.Methods From Jan 2008 to July 2012,6 patients who suffered from hepatic tumors underwent selective ipsilateral portal vein embolization (PVE) due to insufficient future remnant liver volume (FRLV) before second-stage major hepatic resection.Results Technically,all six PVE were completed successfully with only minor liver function damages.The average FRLV increased from (474.33 ± 89.19)cm3 to (722.67 ± 151.51) cm3 (t =-5.587,P =0.003).The average tumor burden (total tumor volume)increased from (134 ± 181) cm3 to (270 ± 346) cm3 (t =-1.64,P =0.16).Five cases underwent secondstage major hepatectomy 6 weeks after PVE,while in 1 case a resection attempt was abandoned because of uncontrolled tumor growth during the period.During the follow-up period (median 37 months),1 died,4 survived,2 were tumor-free.Conclusions Selective portal vein embolization is a safe and effective method to induce hepatic hypertrophy in the appropriate clinical setting.Before PVE,hepatic tumor should be controlled beforehand with chemotherapy or TACE to ensure the scheduled second-stage hepatectomy.

ABSTRACT

Objective To study the long-term result of thrombectomy and thrombolysis for acute mixed deep vein thrombosis(DVT)of the lower extremity. Methods Clinical data of 142 patients treated for acute mixed DVT from September,1991 to June,2005 were reviewed.There were 77 patients treated by thrombectomy.Among these 77 patients there were 49 patients whose common iliac vein was occluded or stenosis.All the 77 patients received territorial transfusion with urokinase and hepafin after operation.The other 65 cases were treated by systemic thrombolysis with urokinase and heparin. Results Two weeks after thrombectomy or thrombolysis,the circumference difference between bilateral limbs was occlusive from (4.3±2.2)cm to(0.6±0.5)cm in thrombectomy group,and from(3.9±2.5)cm to(1.6±0.9)cmin thrombolysis group(t=-8.346,P=0.000).Patients were followed up for an average of(49±42)months.The circumference difference between bilateral limbs was reduced to(0.5±0.4)cm in thrombectomy group and(1.4±1.3)cm in thrombolysis group respectively(t=-5.764,P=0.000).The sequela morbidity in thrombectomy group was less than that in thrombolysis group(P<0.05).The morbidity of edema,pigmentation,and ulcer was 29.9%,15.6%,0%in thrombectomy group and 50.8%,84.6%,6.2%in thrombolysis group.In thrombectomy group,89.6%veins regained patency and 72.7%valves had normal function compared with that in thrombolysis group 30.8%and 9.2%(Z=-8.502.P=0.000).The cure rate was 70.1%in thrombectomy group and 30.8%in thrombolysis group (Z=-4.740.P=0.000).Mortality rate was 3.9%in thrombectomy group,while there was no inhospital death in thrombolysis group. Conclusions For the treatment of acute mixed DVT.especially in protecting the normal valve function,thrombectomy was significantly superior to that of thrombolysis except for causing some mortality.

ABSTRACT

Objective To summarize the experience of fluoroscopy-guided chemical thoracic sympathectomy(CTS) for the treatment of Raynaud's phenomenon.Methods A series of 73 cases of Raynaud's phenomenon(141 upper limbs) treated with CTS from March 2001 to September 2005 in this hospital was chronologically divided into two groups: the Group A between March 2001 and December 2002 and the Group B between January 2003 and September 2005.In the Group A,under the guidance of X-ray fluoroscopy,a needle was punctured through the back skin to the second or the third thoracic sympathetic ganglion beside the thoracic vertebrae and 2 ml of 5% phenol was injected.In the Group B,when the needlepoint reached the rear edge of target thoracic vertebra,2~3 ml of anesthetic was injected.Then the needle was advanced sequentially untill the needlepoint reached the sympathetic ganglion.Other manipulation was the same with the Group A. Results The incidence of pneumothorax in the Group A(28.4%,19/67) exceeded greatly that in the Group B(4.1%,3/74)(?~2=15.773,P=0.000).The effective rate in the Group A(77.6%,52/67) was much lower than that in the Group B(97.3%,72/74)(?~2=12.851,P=0.000).Between the two groups,differences of the incidence of axilla pain(Group A,2 limbs;Group B,5 limbs)(?~2=0.411,P=0.521),bradycardia(Group A,1 case;Group B,nil)(?~2=0.002,P=0.967),and Horner's syndrome(Group A,1 case;Group B,1 case)(?~2=0.000,P=1.000) were not statistically significant.Conclusions Pneumothorax is a common complication of chemical thoracic sympathectomy.Improvement of procedure can reduce the incidence of pneumothorax and increase the effective rate.

ABSTRACT

SUMMARY Tuberculous aneurysm of the aorta is a very rare disorder. There have been only 50 reported cases of tuberculous aneurysm since 1895 till now, of which 88% were false aneurysms with majority being single in number. And only four were found to have multiple tuberculous aneurysms. The mean ages of the patients were 50?16 years. Treatment of tuberculous aortic aneurysm must be a combined medical and surgical approach. Once tuberculous aneurysm is identified, surgery must be performed promptly. The size of the aneurysm does not influence the need for surgery. A 70-year-old male with intermittent episodes of abdominal pain after receiving an inappropriate antitubercular therapy for pulmonary tuberculosis was diagnosed as multiple false tubercular aneurysm of abdominal aorta. An aneurysm of base 3.3 cm and greatest diameter 5 cm?6 cm was seen just above the opening of Coeliac trunk. Also at the dorsal aspect of abdominal aorta and superior mesenteric artery junction and ventral aspect of renal artery false aneurysms were seen, each with the size of 1 cm in diameter. Apart from antitubercular and antimicrobial treatment, first line surgery Endovascular Exclusion of Abdominal Aortic Aneurysm was performed for ruptured false abdominal aortic aneurysm. Even before the second line surgery, smaller abdominal aortic aneurysms got ruptured and the patient ’s party gave up further treatment. Finally the patient died of gastrointestinal haemorrhage.

ABSTRACT

Objective To investigate the therapeatic effects of chemical thoracic sympathectomy (CTS) for Raynaud disease. Methods A niddle was injected into the first or second thoraic vertebra from back. A X-ray examination was performed to definite the position of the niddle tip. One millilitre of urographine was injected to determine if it was infused into thoracic cavity. If not, 2 ml of 5% phenol was injected and the niddle was removed. Results Within 10 minutes both pairs of the hands of the two patients with Raynaud's disease turned into flushing and warm from pallor and cool after CTS. Ice-water test changed to negative. Conclusions CTS is of simple, microinvasive and low cost procedure for Raynaud's disease.

ABSTRACT

Objective To analyze retrospectively the effect on patency of arterial bypasses combined with arteriovenous fistulae in patients with poor run-off. MethodsA retrospective analysis was made based on twenty-six patients with severe lower extremity arteries ischemia and poor run-off, undergoing arterial bypasses combined with arteriovenous fustulae. ResultsAmong the 28 diseased extremities in 26 patients,14 cases received bypass combined with deep arteriovenous fistulae(saphenous vein),and twelve underwent operations combined with superficial arteriovenous fistulae(popliteal vein,tibialis posterior vein).The short term patency rates in these two groups were both 78.6%.The two year′s patency of the bypasses combined with deep fistulae was 78.6%,that of combined with superficial fistula was 57.1%.ConclusionsArtery bypasses combined with arterovenous fistulae could improve the patency rates of the synthetic grafts in patients with severe lower extremity arteries ischemia and poor run-off.

ABSTRACT

Objective To evaluate the complicatio ns after thrombectomy for deep vein thrombosis (DVT) of the lower extremity. Methods Thrombectomy was under taken for 143 patients using Fogarty catheter, then local thrombolysis and antic oagulation was undertaken by a indwelling catheter in the great saphenous vein. Results The total recurren ce rate of DVT was 12.6%(18/143), whereas the early recurrence rate without loc al thrombolysis and anticoagulation was 29.8%(14/47). The recurrence rate was 1 8.9%(14/74) against the background of Cockett syndrome, and 5.8%(4/69) withou t Cockett syndrome. Other complications included lymphatic fistula in 4 cases (2 .8%), pulmonary embolism, vena cava thrombosis, massive haemorrhage, and incisi onal infection in one each, death ensued in 3 (2.1%). ConclusionsThe recurrence rate of DVT could be low ered by management of the stenosis or occlusion of common iliac vein and local thrombolysis and anticoagulation. Thrombectomy should be the first choice of the rapy for DVT.
