RESUMO

Objective@#To evaluate the safety and efficacy of DSA-guided percutaneous application of ethanol sclerotherapy combined with lauromacrogol foam sclerotherapy for the treatment of hyper-backflow venous malformations.@*Methods@#The clinical data of 72 cases of hyper-backflow venous malformation of head and neck from August 2012 to June 2016 by DSA-guided percutaneous puncture sclerotherapy were analyzed retrospectively. Based on the method of sclerotherapy, the patients were divided into group A and B. Group A was treated with ethanol combined with lauromacrogol foam, and Group B was treated with lauromacrogol foam alone. All patients were followed up for 12-24 months (mean 14.3 months). The curative effects and postoperative adverse responses were analyzed by comparision.SPSS 19.0 software was applied, effective rate and adverse reaction rate were examined by chi square test.P<0.05 was considered as statistically significant.@*Results@#Group A(37 cases), cure was achieved in 10, basic cure in 21 and effective response in 3, ineffective response in 3, with a total efficiency of 91.9%(34/37). There were 3.2 average injections. The mean dose of sclerosant foam used in each patient was 220 mg and ethanol 13.6 ml. Group B(35 cases), cure was achieved in 5, basic cure in 15 and effective response in 4, ineffective response in 11, with a total efficiency of 68.6%(24/35). There were 4.8 average injection times. The mean dose of sclerosant foam used in each patient was 322 mg. There was statistically significant difference in total efficiency of 2 groups (χ2=6.245, P<0.05). The main adverse effect were tissue necrosis, nerve injury and limitation of mouth opening. There was no statistically significant difference in adverse effect of 2 groups (P>0.05).@*Conclusions@#DSA-guided percutaneous application of ethanol sclerotherapy combined with lauromacrogol foam sclerotherapy for the treatment of hyper-backflow venous malformations is safe and effective with fewer complications.This technique is especially useful for the hyper-backflow type of venous malformations.

RESUMO

Cervical and intracranial arterial evaluation is an important issue for acute ischemic stroke (IS). Objective Compare the use of the neurovascular ultrasound examination (NVUE) to digital subtraction angiography (DSA) in acute IS patients for diagnosing significant extracranial and intracranial arteriopathy. Method Nonconsecutive patients with IS or transient ischemic attack admitted within 12 hours of the onset of symptoms were evaluated retrospectively. Standardized NVUE and DSA were done in all patients within the first 120 hours of hospital admission. Results Twenty-four patients were included in the study. Compared to DSA, the NVUE demonstrated 94.7% sensitivity and 100% specificity for identifying symptomatic extracranial and/or intracranial arteriopathy. Conclusion The standardized NVUE technique demonstrated high sensitivity and specificity compared to DSA for diagnosing arterial abnormalities in acute IS patients. .


A avaliação cervical e intracraniana é uma etapa importante no AVC isquêmico (AVCi) agudo. Objetivo Comparar o uso do ultrassom neurovascular (USNV) com técnica padronizada e a angiografia digital (AD) em paciente com AVCi agudo no diagnóstico de doença arterial significativa extra e/ou intracraniana. Método Pacientes com AVCi e AIT admitidos em até 12 horas do início dos sintomas foram retrospectivamente avaliados. Todos os pacientes foram submetidos a USNV e AD padronizado em até 120 horas da admissão. Resultados Vinte e quatro pacientes foram incluídos no estudo. Em comparação com a AD, o USNV apresentou sensibilidade de 94,7% e especificidade de 100% para o diagnóstico de doença arterial significativa extra e/ou intracraniana. Conclusão O uso de técnica padronizada de USNV demonstrou elevada sensibilidade e especificidade para o diagnóstico de doença arterial significativa extra e intracraniana quando comparado a AD. .

RESUMO

Objective To investigate the origin of prostatic blood-supply by digital subtraction angiography (DSA) and provide references for the arterial embolization of prostatic hyperplasia. Methods A total of 72 male patients with successful selective and super-selective prostatic arterial catheterization angiographies were observed and recorded the original arterial blood-supply of the prostate, number of the prostatic arteries and the predominant blood supply. Results The blood-supply of prostate is very complicated including the original prostatic arterial supply from the inferior vesicle arteries (69); the internal iliac arteries (63); the internal pudendal arteries (52); the inferior rectum arteries (29); the superior vesicle arteries (14). The predominant arterial supply include the internal iliac arteries (37); the inferior vesicle arteries (20); the internal pudendal arteries (6) and the inferior rectum arteries (2). Conclusion Arterial contrast medium angiography can correctly demonstrate and assess the original arterial supply of prostate, providing significant guidance for further interventional embolization.

RESUMO

Objective To analyze the accuracy,sensitivity and safety of multidetector CT angiography(MDCTA) and DSA;furthermore to explore the clinical value of MDCTA in studying the delayed cerebral vasospasm(DCVS) .Methods Delayed cerebral vasospasm was induced in 17 rabbits by injection of autologuous blood into the cisterna magna and followed by a second injection 24 hours later.MDCTA and DSA were carried out at the 7th day before and after the procedure in order to obtain the data of vascular diameter changes for comparative study.Results The basilar artery diameters detected by MDCTA were shown preoperatively as(1.55 ? 0.14) mm and postoperatively as(0.95 ? 0.20) mm;and detected by DSA as(1.61 ? 0.19) mm and(1.00 ? 0.17) mm postoperatively;showing statistically equivalence between the two methods.Conclusions MDCTA is recommended as a reliable,rapid,and minimally invasive diagnostic method,providing a new technique for the delayed cerebral vasospasm research.

RESUMO

Objective To assess the value of transcatheter superselective arterial embolization in treatment of renal traumatic hemorrhage. Methods 20 patients underwent digital subtraction angiography with definite diagnosis before embolization. Embolization materials used in the study were gelfoam sponge chips and steel coils including 14 cases of segmental arteries with their branches through superselective renal arterial embolization. 6 cases were treated by selective renal arterial embolization. Results After renal artery embolization, macroscopic hematurin disappeared on 3th to 5th day after the procedure. With an average of 29 months of follow-up, there was no recurrent hemorrhage associated with normal renal function and blood pressure. Conclusions Superselective renal arterial embolization has advantages of less aggression, less complications, and good hemostatic efficacy, with maximal preservation of renal tissue and function for treatment of mild and moderate renal injuries.
