Efficacy analysis of stenting in patients with internal carotid artery cavernous segment symptomatic stenosis / 中国脑血管病杂志

Objective To evaluate the safety,effectiveness,and middle or long-term efficacy of endovascular stenting of internal carotid artery stenosis at the cavernous segment. Methods Thirty-two patients underwent endovascular stenting at the cavernous segment of internal carotid artery from January 2012 to February 2015 were enrolled retrospectively. Angioplasty and stenting were conducted using Apollo or Winspan stent system. The improvement of internal carotid artery cavernous segment stenosis and perioperative safety and the results of the medium and long-term follow-up of the 2 kinds of stents were observed. Results All the 32 patients achieved technical success. The symptoms of cerebral ischemia of the patients were relieved significantly. The length of the stenosis at cavernous segment of the internal carotid artery was 4 to 13 mm (mean,7. 2 ±2. 9 mm). The stenosis rate from 82 ± 7% before treatment decreased to the 24 ± 7% . One patient had perioperative complication (4. 7%),26 of them were followed up with DSA,and 6 were lost to follow-up. The follow-up period ranged from 7 to 29 months (mean,16 ± 7 months). During the follow-up period,1 patient had intracerebral hemorrhage,1 had cerebral infarction,and none of them died. Four patients had in-stent restenosis,three of them used Winspan stents, and 1 used Apollo stents. Conclusion The patients should be screened strictly,particularly paying attention to the length of lesions. Endovascular stent angioplasty for the treatment of internal carotid artery cavernous segment stenosis is a safe and effective method.

Angiomatosis cavernosa cerebral múltiple en pediatria / Cavernous angiomatosis in children

Las malformaciones vasculares intracraneanas en niños son lesiones congénitas debidas a alteraciones en el desarrollo de la red arteriocapilar. Se presentan por orden de frecuencia: malformaciones arteriovenosas, angiomas cavernosos o cavernomas, angiomas venosos y telangiectasias. Se describe el caso de un paciente de 3 años de edad con diagnostico de angiomatosis cavernosa cerebral múltiple derecha, con variadas manifestaciones clínicas, como crisis convulsivas focales complejas motoras, alteración en la marcha, hemiparesia izquierda, entre otras que están relacionadas con esta patología. Los casos descritos de angiomatosis cavernosa múltiple son en pacientes adultos, es evidente entonces que este caso clínico contribuye a una identificación en la literatura por sus características especiales de presentación clínica y manejo en pacientes pediátricos.

Intracranial vascular malformations are congenital lesions due to alterations in network development arterioca-pillary. Are presented in order of frequency, arteriovenous malformations, cavernous angiomas or cavernomas, venous angiomas and telangiectasias. This paper describe the case of a 3 year old boy diagnosed with multiple peripheral cerebral cavernous angio-matosis right with different clinical symptoms such as focal motor seizures, left hemiparesis, among others related to this pathology. Multiple cavernous angiomatosis has been described in adult patients, it is clear then that the case report contributes to the literature identifying special characteristics of clinical presentation and management in pediatric patients.

Diffuse Hepatic Hemangiomatosis without Extrahepatic Involvement in an Adult Patient

We report an extremely rare case of a diffuse hepatic hemangiomatosis without extrahepatic involvement in an adult. The imaging findings of this tumor were similar to those of a hepatic hemangioma and included contrast enhancement with a centripetal filling pattern of the entire hepatic tumor on the delayed phase of a dynamic CT and inhomogeneous diffuse uptake of the entire tumor on blood-pool images obtained five hours later on a 99mTc-labeled red blood cell scan. Despite its rarity, diffuse hepatic hemangiomatosis can be suggested in adult patients with diffusely involved hepatic tumors showing the radiological findings of a hepatic hemangioma.

A Case of Lymphangiomas(So-called Combined Venous Lymphatic Malformation) Resulting in Orbital Abscess

Orbital lymphangiomas are benign vascular hamartomas that may be found in the conjunctiva, the eyelids, the orbit, or elsewhere in the head and neck region. Deep lymphangiomatous lesions are classically characterized by acute onset of a fulminant proptosis resulting from spontaneous hemorrhage within the orbit. Complete surgical excision is often difficult because of the infiltrative nature of the tumor.We report one case of lymphangiomas considered to be associated with cavernous hemangioma which could not be removed completely by several surgical excisions and was exenterated because of orbital abscess of unknown origin and septic condition.

Sclerosis of hepatic cavernous hemangioma: CT findings and pathologic correlation

We report a case of hepatic cavernous hemangioma with computed tomographic findings of well demarcated nodular lesser attenuation foci within the main low attenuation mass on precontrast scans and non-enhancement of the foci even on the delayed contrast scans. These have been described as one of the atypical findings of cavernous hemangioma earlier in the literature. Surgery proved that sclerosis accounted for the hypodense nodular densities within the hepatic cavernous hemangioma.
