Treatment of superior mesentery arterial embolism with transcatheterizing thrombolysis

Journal of Interventional Radiology.1994;0(02):-.

Objective To discuss the treatment of superior mesenteric arterial thrombo-embolism through superior mesenteric arterial angiography and transcatheterizing thrombolysis. Methods After diagnosis of superior mesenteric arterial thrombo-embolism through percutaneous transluminal angiography, the embolism was cleared out and then the inner tip of catheter was implanted within embolus for slow continuously thrombolysis with the outer tip of catheter connected to the infusion pump. Result Four cases succeeded with thrombolysis; 3 cases were performed with partial small intestinal excision with necrosis. Two cases healed. One case died of heart failure postoperatively and another case died of massive digestive tract hemorrhage. Conclusions Angiography can help to confirm the position of superior mesentery arterial thrombosis and the extent of intestinal ischemia. Early intrathrombus catheterization for clear out and thrombolysis can obtain satifactory prognosis.

Cardiovascular changes during vertebroplasty don't due to bone cement leakage

Long CHEN ; Caifang NI

Journal of Interventional Radiology.2001;0(06):-.

The rather serious compliation of vertebroplasty is caused by bone cement leakage into adjacent structure but recent research suggests that even without cement leakage during vertebroplasty,patients could also experience with cardiovascular changes sometimes. Cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be responsible for these changes. (J Intervent Radiol,2006,15: 377-381)

Journal of Interventional Radiology.2001;0(06):-.

Objective To evaluate the clinical value of the preoperative intra-arterial embolization of the nasopharyngeal angiofibromas. Methods The treatment group of 7 male patients with the nasopharyngeal angiofibromas were undergone angiographic evaluation and embolization of tumor-feeding vessels before surgery. All patients were embolized with gelfoam particles and PVA. The control group of 7 patients received surgical treatment without preoperative embolization. We compared the volumes of intraoperative bleeding and the blood transfusions during oprations between the two groups. Results All patients achieved symptomatic remission,with no complications. Comparing with the control group,the amount of intraoperative bleeding and the blood transfusions during operations were much less in the treatment group submitted to endovascular embolirzation.Marked edema in the peripheral region of tumor of the treatment group made the tumor easy to be dissociated. Conclusion The intraoperative bleeding can be reduced significantly by preoperative embolization of supplying arteries to the nasopharyngeal angiofibromas,therefore it should be used routinely as an adjunct to surgery.

Journal of Interventional Radiology.2001;0(06):-.

Objective To evaluate the clinical value of pre-operative double embolization for nasopharyngeal angiofibroma. Methods Digital subtraction angiography(DSA) was carried out in 7 cases of nasopharyngeal angiofibroma. In six cases,the supplying arteries originated from the maxillary artery and the branches arising from internal carotid artery underwent double embolization-direct percutaneous puncture embolization and selective embolization of blood supplying arteries. In another case,the supplying artery originated from maxillary artery was only undertaken selective embolization for the feeding arteries. Results All the tumor masses reduced in vonlume obviously or even disappeared on the angiography after embolization. Conclusions Pre-operative double embolization for nasopharyngeal angiofibroma could be a necessary additional treatment method. (J Intervent Radiol,2006,15: 342-344)

Journal of Interventional Radiology.2001;0(06):-.

Objective To study the application of super-selective external carotid artery embolization in head and neck diseases. Methods DSA and super-selective external carotid artery embolization were carried out in 41 cases of head and neck diseases including 12 cases of epistaxis,7 nasopharyngeal fibroangioma,1 traumatic arterial bleeding,14 vascular malformation,and 7 malignancies. Results No recurrence of nose bleeding after embolization of epistaxis was seen within 6 - 12-month follow up. The operative bleeding was reduced significantly by preoperative embolization in nasopharyngeal fibroangioma. No recurrence of bleeding was achieved after embolization of traumatic artery. Among the cases of vascular malformation,3 were proven to be significantly effcient,6 effcient,and 5 inefficent in the 6 - 12-month follow up. Among the 7 malignant cases,3 survived more than 2 years. Conclusion Super-selective external carotid artery embolization is safe and effective in the treatment of head and neck diseases.

Journal of Interventional Radiology.2001;0(06):-.

Objective To summerize the clinical experience of 23 cases of carotid cavernous fistula(CCF) and discuss the treatment strategy. Methods Retrospectively analyzed 23 patients(11 males and 12 females) of CCF,including 14 patients with Barrow type A,1 with type B,1 with type C and 7 with type D. Results Vascular approach for embolization was undertaken in 20 cases by transarterial access and 2 via venous route while 1 case was given up. Among them,9 cases obtained complete occlusion by simple balloon embolization and 5 were treated by direct occlusion of internal carotid artery. Another 5 cases used NBCA glue for the occlusion,1 case was embolized by gelatin-sponge particulates combined with compression of carotid artery,2 cases were treated by coil embolization of cavernous sinus and 1 case was only managed by carotid compression maneuver. We achieved satisfactory clinical results with 21 patients cured and 2 patients improved. Conclusion Complexity and refractory are the characteristic of CCF,and endovascular treatment should be the major choice of treatment. (J Intervent Radiol,2006,15: 323-326)
