Background The major consequence of pulmonary arteriovenous malformations （PAVMs） is the direct inflow of blood from the pulmonary artery to the pulmonary vein which induces hypoxemia. Severe complications include transient ischemic attacks, paradoxical embolization in the central nervous system, massive hemoptysis or hemothorax, etc. The conventional treatment is surgical intervention. However, this can be very traumatic and dangerous. endovascular embolization has advantages over surgery such as a faithful therapeutic effect, a low complication rate, repeatability, etc. Methods Patients （n=-23） with symptomatic PAVMs underwent endovascular embolization; 11 were males and 12 were females, with ages ranging from 6 months to 58 years. During the embolization, microcoils were applied in 6 cases and standard steel coils were used in 17 cases. Results Multiple PAVMs lesions were found in 16 cases and single PAVMs lesion was found in 7 cases. Embolotherapy was carried out 28 times for 23 patients. The success rate was 100%. The results of pulmonary arteriography after treatment showed that single lesion disappeared completely while the main abnormal vessels in multiple lesions also disappeared. The mean blood oxygen saturation increased from （78.04＋8.22）% to （95.13＋3.67）% after the procedure. A correlated groups t test showed changes in blood oxygen saturation before and after embolization （t=9.101, P 〈0.001）. Symptoms of cardiac insufficiency disappeared in 5 cases and vascular murmur in the chest disappeared in 13 cases. After embolization, mild chest pain occurred in 11 cases, small amounts of pleural effusion occurred in 5 cases, and 1 patient died 2 months later because of a pyogenic infection secondary to the pulmonary infarction. Among the 22 remaining cases, with overall follow-up ranging from 18 months to 12 years, general conditions were fine, daily lives were normal and there were no neurologic symptoms or signs, except for 3 patients with diffused PAVMs who had persistent blood oxygen saturation between 85

We report a case of contrast-induced encephalopathy after endovascular embolization of an anterior communicating artery aneurysm.A 59-year-old woman was admitted to Tongliao Hospital for neurointerventional treatment due to a left anterior communicating artery aneurysm.She had a history of hypertension,which was controlled by regular medication.The contraindications were eliminated following a preoperative examination,and head computed tomography(CT)showed no abnormalities.After evaluation,interventional embolization was performed.Three hours postoperatively,the patient complained of a headache on the right side,which was accompanied by frequent nausea.Emergency head CT showed no intracranial hemorrhage,obvious brain tissue edema in the right cerebral hemisphere,blurred sulcus/gyrus,or metal artifacts(spring coils)in the left frontal lobe.The patient was diagnosed with contrast-induced encephalopathy(CIE).This patient achieved good prognosis through timely and reasonable treatment.CIE is very rare clinically,improper treatment may lead to irreversible clinical outcomes;it should cause alarm to doctors.

Objective To sum up our experience of endovascular embolotherapy with different embolic agents for intracra-nial aneurysms. Methods From June 1994 to January 2003 a total of 39 patients with intracranial aneurysms were admitted and treated with endovascular embolization in our hospital. Among the 39 patients 19 suffered from subarachnoid hemorrhage, six from transient ischemia, six from decreased vision, 7 from oculomoter nerve paresis and one from trigem-inal neuralgia. Hunt’ s scale before operation showed scale 1 in 27 patients, scale 2 in five, scale 3 in six and scale 4 in one. Balloons ( French BALT Company) were used in 5 patients, mechanical detachable spirals (MDS) were used in 18 patients, Guglielmi detachable coils (GDC, Boston Scientific Co.) were used in 10 patients, and self- made copper coils (MC) and MDC were used in six patients. Results Of the 39 patients one died after embolization, three patients had permanent complications caused by aneurysm rupture, 35 patients were reexamined by plane head film, CT, MRA, TCD ( trancranial Doppler) after embolization, which showed complete occlusion in 30 patients and over 90% occlusion in five, and no subarachnoid hemorrhage or aneurysm reoccurred. Conclusion embolization with GDC is an ideal method in treatment of intracranial aneurysms.

Simultaneous embolization of a spontaneous porto-systemic shunt and intrahepatic arterioportal fistula:A case report

BACKGROUND Hepatic encephalopathy(HE)is a frequent and debilitating complication of chronic liver disease.Recurrent HE is strongly linked with spontaneous portosystemic shunts(SPSSs).Intrahepatic arterioportal fistulas(IAPFs)occur rarely but pose a major clinical challenge and may lead to or worsen portal hypertension.Herein,we present a rare case of recurrent HE secondary to a SPSS combined with an IAPF.CASE SUMMARY A 63-year-old female with primary biliary cirrhosis presented with recurrent disturbance of consciousness for 4 mo.SPSS communicating the superior mesenteric vein with the inferior vena cava and IAPF linking the intrahepatic artery with the portal vein were found on contrast-enhanced abdominal computed tomography.The patient did not respond well to medical treatment.Therefore,simultaneous embolization of SPSS and IAPF was scheduled.After embolization,the symptoms of HE showed obvious resolution.CONCLUSION The presence of liver vascular disorders should not be neglected in patients with chronic liver disease,and interventional therapy is a reasonable choice in such patients.

Background:Carotid cavernous fistula is a rare complication that is typically associated with head trauma and skull base fractures.The traumatic bilateral carotid cavernous fistula are significantly rarer.Case presentations:We report a case of a 61-year-old man presenting with unilateral exophthalmos,swollen eyelids,conjunctival congestion,and edema etiologically associated with severe trauma.Thereafter,the patient demonstrated symptoms of contralateral oculomotor nerve injury caused by skull base fracture,such as ptosis of eyelid,dilated pupils,and eye movement disorder,and was diagnosed with bilateral carotid cavernous fistula.Conclusions:The patient recovered after undergoing endovascular embolization of bilateral cavernous sinus fistulas.The patient demonstrated the classic symptoms of an extremely rare condition known as bilateral carotid cavernous fistula,in only one eye.Reporting and analyzing this case will help us elucidate the underlying mechanisms of this disease.

＜正＞Objective To retrospectively analyze the diagnosis and endovascular embolotherapy of traumatic carotid cavernous fistulae in 25 patients. Methods Twenty - five patients （ 16 men and nine women） with traumatic carotid cavernous fistulae, aged 16 - 52 years, were treated with endovascular embolization in our hospital from November 1992 to January 2003. Em-bolic agents mainly included detachable balloon, self - made dissociative tungstenic coils and mechanical detachable spirals （MDS）. Femoral approach was used in 22 patients and carotid approach used in 3 patients. Results Nineteen patients preserved carotid artery patency, and six patients obtained occlusion of internal carotid artery. Conclusion endovascular embolotherapy is the first choice in treating traumatic carotid cavernous fistulae. It has the effect of occluding fistulae, eliminating intracranial bruit, saving visual sight, preserving internal carotid artery patency and improving brain ischemia.
