Symptomatic splanchnic artery dissection：imaging diagnosis and interventional treatment / 介入放射学杂志

Objective To summarize the experience in the diagnosis and treatment of symptomatic splanchnic artery dissection. Methods A total of 21 patients with symptomatic splanchnic artery dissection, who were admitted to the Affiliated First Hospital of China Medical University during the period from June 2006 to March 2014, were included in this study. Combined with the literature, the clinical data, including the diagnosis and treatment, were analyzed. Results Contrast-enhanced abdominal CT and CT angiography revealed superior mesenteric artery dissection in 15 cases, celiac artery dissection in 5 cases and splenic artery dissection in one case. Conservative therapy was employed in 5 patients; among them one was complicated with hepatic artery thrombosis. Of the 16 patients who received endovascular stent placement, additional intestinal resection was performed in 2 and transcatheter thrombolysis treatment in other 2. No procedure-related severe complications occurred in perioperative period. All the patients were followed up for 2-74 months (mean of 19.1 months). In patients who received endovascular stent placement, the abdominal pain and the bloody stool were relieved or disappeared, and no abdominal pain recurred. CT angiography showed that in-stent blood flow was fluent, the stent was in good position, and neither stenosis nor thrombosis was observed. One patient with superior mesenteric artery dissection died of stroke three months after the treatment. Conclusion It is very important to make early diagnosis and to adopt early treatment for symptomatic splanchnic artery dissection. CT angiography can confirm the diagnosis in most cases, but attention should be paid to some atypical manifestations. For the treatment of splanchnic artery dissection, endovascular stent placement is mini-invasive, safe and reliable.

Hemodynamics analysis of a stented aortic bifurcation / 生物医学工程学杂志

In the treatment of aortic arch dissections involving left subclavian artery (LSA), a double stent implantation is sometimes required to treat the disease of each branch. In this study, aortic arch and LSA were modeled by using Pro/engineer wildfire3. 0. Two deployed stents were inserted in the aortic arch and LSA. There are 3 kinds of model according to the stent struts protruding into the inlet of the collateral branch, and the healthy aortic arch model without any stent was provided as a reference case. We used computational fluid dynamics (CFD) to investigate the flows in the model stents and focused on the changes of blood speed and wall shear stress caused by the implanted stents of different models. The results showed that the stent strcuts protruding into the inlet of LSA induced the conspicuous decrease of blood speed and the emergence of large-scale low shear stress,which would cause thrombogenesis, neointimal hyperplasia and result in in-stent restenosis, so it would be judicious to use dedicated bifurcated stents for treatment of bifurcation lesions.

VX2 carcinoma in rabbits after radiofrequency ablation: Differentiating residual tumor from inflammation using enhanced CT versus histopathology / 中国介入影像与治疗学

Objective To distinguish residual tumor from inflammation after radiofrequency ablation (RA) for hepatic VX2 carcinoma in rabbits according to the comparative study between CT and pathological findings.Methods CT and pathologic examination were performed in different stages of RFA for rabbits hepatic VX2 models,and their different performances were observed.Results Marginal enhancement band was showed with enhanced CT of both residual tumor and inflammation.Moreover,liver tissues peripheral to enhancement band were in gradual weaken pattern.The enhancement band of inflammation was most obvious on the 2~(nd) day after RFA,but weakened gradually and disappeared two weeks later.Conclusion The residual tumor and inflammation could not be distinguished through enhanced CT scanning within 1 week after RFA.Low intensity lesions with peripheral enhancement 2 weeks after RFA should be recognized as residual tumor.

Mid-term follow-up of the percutaneous angioplasty of the occlusive aortoiliac artery diseases / 中华放射学杂志

Objective To evaluate the mid-term follow-up of the pereutaneous angioplasty of the occlusive acrtoiliac artery diseases.Methods The data of 30 patients who had distal abdominal aorta and bi-lateral iliac artery stenosis or occlusion and treated by percutaneous angioplasty were retrospectively reviewed.They are 24 males and 6 females,aged from 35 to 75 years (average 55 ± 10 years). The interventional procedures include wire-guided canalization,thrembolysis,balloon angioplasty and stents implantation.They were followed up by telephone,letter or visiting after discharged.Results Twenty-six patients with aarto-iliac are revascularized successfully.Three cases failed.Of them,one failed because only one side of iliac artery and aorta were successfully canalized while the eontralateral not,one failed to revascularize both the aorta and the iliac artery,the other one failed due to the ihac rupture and replaced by WallGraft implantation.Two cases had distal thrombosis during the procedure.One case was amputated due to the aggravated isebemia of the right lower extremity after the revascularization failed.Twenty-seven cases were followed uo after 1 to 112 months,averaged (41±9) months.One case showed that the iliac artery was uncanalized after 6 months.One case showed bilateral iliac artery occlusion during 25 months follow-up and re-occluded 3 months after balloon angioplasty and finally had stent implanation in bilateral iliac artery.The other patients had no aggravated symptom of recurrence.Conclusion The percutaneous angioplasty is a good choice for occlusive aorto-iliac artery disease,showing good recovery during mid-term follow-up.

Significance of nonbronchial systemic artery embolization for massive hemoptysis / 中华放射学杂志

Objective To emphasize the importance of embolization of nonbronchial systemic arteries in treatment of acute and life-threatening massive hemoptysis.Methods In a series of 146 patients with hemoptysis who underwent bronchial artery embolization,we found 12 cases whose blood supply were from 17 nonbronchial systemic arteries and hemoptysis was more than 300 ml blood within 24 hours.Embolic materials included absorbable gelatin sponge(GS),kelp micro gelatin(KMG),polyvinyl alcohol(PVA) particles and metal coils. Results In the 12 cases with 17 nonbronchial systemic arteries (4 were intercostal,3 internal mammary,3 thyrocervical trunk,3 inferior phrenic,1 left gastric,2 originated from the inferior aortic arch,and 1 originated from anterior abdominal aortic wall).Five cases were embolized by GS alone,2 cases by KMG,3 cases by GS+PVA,and 2 cases by GS+PVA+metal coils.Eight cases were performed embolization once,3 cases were performed twice and 1 case was performed three times.No significant complications developed related to embolization,except that 1 patient had transient eyesight decrease after embolization of thyrocervical trunk and 2 patients had chest pain after embolization of intercostal artery which resovled without any treatment.Conclusions During bronchial artery embolization for hemoptysis patients,all supplying artery should be searched and found.Even after successful embolization of bronchial arterys for hemoptysis patients,nonbronchial systemic arterial supply should still be taken into account.

Clinical use of interventional therapy for occlusive lesion in iliac arteries and femoral arteries of 42 cases / 中华放射学杂志

Objective To evaluate the efficacy of interventional therapy of occlusive lesion in iliaco- femoral arteries. Methods During Feb 2001 to Feb 2006, 42 patients (30 male and 12 female) with arterial occlusive lesions in iliac artery and/or femoral artery accepted interventional therapies. The interventional therapeutic process included local thrombolytic therapy through endoarterial catheter, artery recanalization by guide wire, pereutaneous transluminal angioplasty (PTA) and stent. After interventional operation, patients were administrated anticoagulant and antibiotics one week. Follow-up interval ranged 2 years. Wilcoxon test and t test were used for statistics. Results Immediate technical successful rate was 97.6% (41/42),the secondary technical success rate was 100.0% (42/42). The arterial occlusions were resolved successfully (local thrombolytic therapy in 26 cases, recanalization by guide wire in 31 cases, PTA in 33 cases and 60 stents in 31 cases). There were no severe complications (such as angiorrhexis, perforation) during interventional procedure. The symptoms of lower limb ischemia were palliated or vanished in all patients after interventional therapy. The ankle-brachnial index(ABI) of diseased extremities increased from pre-operation 0.34±0.14 to past-operation 0.65±0.10 (t=25.924, P <0.01 ). During the follow-up, 11/42 (26.2%) iliac or femoral artery (treated with local intra-arterial thrombolysis, PTA and stent) occurred restenosis. After PTA and stenting, the restenosis arteries became fluent successfully. The primary patency rate was 92.8% (39/42)and the secondary patency rate was 100.0% (42/42)1 year after the procedure. Two years after the procedure, the primary patency rate was 71.4% (30/42) and the secondary patency rate was 97.6% (41/42). Conclusions Interventional therapy (including local thrombolysis, recanalization, PTA and stent) is an effective and safe therapy for occlusive lesion in iliaco- femoral arteries.

Treatment of chronic hepatic cirrhosis with autologous bone marrow stem cells transplantation in rabbits / 中华放射学杂志

Objective To evalute the feasibility of treatment for rabbit model with hepatic cirrhosis by transplantation of autologous bone marrow-derived stem cells via the hepatic artery and evaluate the effect of hepatocyte growth-promoting factors (pHGF) in the treatment of stem cells transplantation to liver cirrhosis.To provide empirical study foundation for future clinical application.Methods Chronic hepatic cirrhosis models of rabbits were developed by subcutaneous injection with 50% CCl4 0.2 ml/kg.Twenty-five model rabbits were randomly divided into three experimental groups,stem cells transplant group (10),stem ceils transplant + pHGF group (10) and control group (5).Autologous bone marrow was harvested from tibia of each rabbit,and stem cells were disassociated using density gradient centrifugation and transplanted into liver via the hepatic artery under fluoroscopic guidance.In the stem cells transplant + pHGF group,the hepatocyte growth-promoting factor was given via intravenous injection with 2 mg/kg every other day for 20 days.Liver function tests were monitored at 4,8,12 weeks intervals and histopathologic examinations were performed at 12 weeks following transplantation.The data were analyzed using analysis of variance Results Following transplantation of stem cells,the liver function of rabbits improved gradually.Twelve weeks after transplantation,the activity of ALT and AST decreased from (73.0±10,6)U/L and(152.4± 22.8) U/L to (48.0±1.0)U/L and(86.7±2.1)U/L respectively; and the level of ALB and PTA increased from (27.5 ±1.8)g/L and 28.3% to (33.2 +0.5)g/L and 44.1% respectively.The changes did not have statistically significant difference when compared to the control group(P >0.05).However,in the stern cellstransplant + pHGF group,the activity of ALT and AST decreased to (43.3±0.6)U/L and (78.7±4.0)U/L respectively and the level of ALB and PTA increased to (35.7 ±0.4)g/L and 50.5% respectively.The difference was statistically significant when compared to the control group(F=47.38,23.52,52.27,174.45,P < 0.05).In pathohistology,the degeneration and necrosis of hepatic cells and the degree of fibrous hyperplasia in stem cells transplant group were less obvious than that of the control group.Hepatic pseudo-lobules persisted.The improvement of liver architecture in the stem cells transplant + pHGF group was more evident than that in stem cells transplant only group.In addition,there were more hepatic CD34 <'+> cells within liver tissue in the stem cells trasplant group when compared to the control group,and the most hepatic CD34<'+> cells were seen in the stem cells transplant + pHGF group.Conclusion Autologous bone marrow stem cells transplanted via the hepatic artery for the rabbit hepatic cirrhosis model is an effective method to treat hepatic cirrhosis.The hepatoeyte growth-promoting factor can help to enhance the results of treatment.

Objective To evaluate the embolization efficiency,short term clinical effect and adverse reactions of trisacryl gelatin microspheres in interventional treatment of hepatic carcinoma. Methods Twenty three cases of hepatic carcinoma (34 foci)were given 0.5-6 ml of microspheres mixed with some contrast medium via catheter after injection of chemodrugs and lipiodol 3-5 ml; and simultaneously observing the appearance of slow down of blood flow and vascular cast formation to stop the procedure. Enhanced CT or MR and AFP were performed every 1 month after the first procedure. Treatment needed to be repeated whenever the foci or new ones were enhanced in CT scans or increase of AFP value. The clinical effect and adverse reactions were also observed. Results The positive response rate was 39.1% (CR+PR). There were 9 cases of PR,13 cases of NC and 1 of PD; but no case of CR. Residual enhancement was observed in 17 foci after first procedure,10 of which received repeated therapy and 3 were embolized completely. The other 11 foci were completely embolized,among them 4 had new residual enhancement during 4-9 mo follow up and 2 were re-embolized completely. Eighteen cases with positive AFP showed obvious decrease in 11,no change in 6 and increase in one. Eighteen cases of pyrexia,11 cases of pain in hepatic region and 6 cases of nausea occurred 5-14 d after the procedure together with vomiting. We also found increase of ALT in 2 cases,BIL of 1 case,and no change of WBC in all cases. Conclusion Trisacryl gelatin microspheres is an excellent embolization agent with better clinical effect and less adverse reaction in the treatment of hepatic carcinoma.
