Embolization of an Insulinoma of the Pancreas with Trisacryl Gelatin Microspheres as Definitive Treatment

Insulinomas are rare, mostly benign neuroendocrine tumors, originating in 99% of cases from the pancreas, that synthesize and secrete insulin, causing symptomatic hypoglycemia. Today the treatment of choice is surgical removal. We present the case of an 84-year-old woman with a symptomatic insulinoma who refused surgery and was treated with arterial embolization using trisacryl gelatin microspheres as definitive treatment.     

Pulmonary Artery Embolotherapy in a Patient with Type I Hepatopulmonary Syndrome after Liver Transplantation

Although liver transplantation (LT) is the only effective treatment option for hepatopulmonary syndrome (HPS), the post-LT morbidity and mortality have been high for patients with severe HPS. We performed post-LT embolotherapy in a 10-year-old boy who had severe type I HPS preoperatively, but he failed to recover early from his hypoxemic symptoms after an LT. Multiple embolizations were then successfully performed on the major branches that formed the abnormal vascular structures. After the embolotherapy, the patient had symptomatic improvement and he was discharged without complications.     

Fatal Peritoneal Bleeding Following Embolization of a Carotid-Cavernous Fistula in Ehlers-Danlos Syndrome Type IV

We report the case of a 25-year-old woman treated for a spontaneous carotid-cavernous fistula in a context of Ehlers-Danlos syndrome type IV. Embolization with a transvenous approach was achieved without complications; however, the patient died 72 hr later of massive intraperitoneal bleeding. At autopsy, no lesion of the digestive arteries was identified. Possible causes of this bleeding are discussed.     

Embolization of the Systemic Arterial Supply via a Detachable Silicon Balloon in a Child with Scimitar Syndrome

Scimitar syndrome is a rare congenital disorder. It is characterized by partial or total abnormal venous drainage of the right lung into the inferior vena cava, which is often associated with anomalous systemic arterial supply to the right lung, congenital cardiac anomalies, hypoplasia of the right lung and bronchial anomalies. Symptoms depend on the degree of the shunt and severity of the associated anomalies, which determine the treatment. We present a 6-year-old boy who was diagnosed as having the adult form of scimitar syndrome during evaluation for recurrent pulmonary infections, and underwent embolization with a detachable silicon balloon of the anomalous systemic arterial supply from the abdominal aorta to the right lower lung lobe. Successful elective surgery was performed 6 months later, in which right pulmonary veins were directed to the left atrium using a Gore-Tex patch by creating an intra-atrial tunnel. The patient has been symptom-free period during 6 months of follow-up, which supports the idea that recurrent pulmonary infections can be eliminated by embolization of the anomalous arterial supply.     

Endovascular Treatment of a Carotid Dissecting Pseudoaneurysm in a Patient with Ehlers-Danlos Syndrome Type IV with Fatal Outcome

We present a patient with Ehlers-Danlos syndrome type IV (EDS IV) with a carotid dissecting pseudoaneurysm causing severe carotid stenosis. This lesion was treated endovascularly. Unfortunately, the patient died of remote vascular catastrophes (intracranial hemorrhage and abdominal aortic rupture). This unique case illustrates the perils of endovascular treatment of EDS IV patients and the need for preoperative screening for concomitant lesions. It also shows that a dissecting pseudoaneurysm can feasibly be treated with a covered stent and that closure is effective using Angioseal in patients with EDS IV.     

Endovascular Treatment of a Ruptured Internal Thoracic Artery Pseudoaneurysm Presenting as a Massive Hemothorax in a Patient with Type I Neurofibromatosis

We report a case of acute hemothorax caused by a left internal thoracic artery pseudoaneurysm rupture in a patient with neurofibromatosis type I, which was successfully treated with endovascular coil embolization.     

Resolution of Large Azygos Vein Aneurysm Following Stent-Graft Shunt Placement in a Patient with Ehlers-Danlos Syndrome Type IV

Ehlers-Danlos syndrome (EDS) type IV is a rare connective tissue disorder associated with thin-walled, friable arteries and veins predisposing patients to aneurysm formation, dissection, fistula formation, and vessel rupture. Azygos vein aneurysm is an extremely rare condition which has not been reported in association with EDS in the literature. We present a patient with EDS type IV and interrupted inferior vena cava (IVC) with azygos continuation who developed an azygos vein aneurysm. In order to decrease flow through the azygos vein and reduce the risk of aneurysm rupture, a stent-graft shunt was created from the right hepatic vein to the azygos vein via a transhepatic, retroperitoneal route. At 6 month follow-up the shunt was open and the azygos vein aneurysm had resolved.     

Spontaneous Rupture of the Hepatic Artery in a Patient with Type 1 Neurofibromatosis Treated by Embolization: A Case Report

We report the case of a 48-year-old man with neurofibromatosis presenting with sudden-onset abdominal pain, profound hypotension, and a drop in hemoglobin. CT scan demonstrated a massive hematoma within the right lobe of the liver with rupture into the peritoneal cavity. Angiography demonstrated diffuse abnormalities of the hepatic circulation with fusifom, ectatic, and stenotic segments. Acute extravasation from a peripheral branch of the right hepatic artery was identified and successfully embolized with subsequent hemodynamic stabilization of the patient. To the best of our knowledge this is the first case report of this kind in a patient with type I neurofibromatosis.     

A Randomized Trial of Endovascular Embolization Treatment in Pelvic Congestion Syndrome: Fibered Platinum Coils versus Vascular Plugs with 1-Year Clinical Outcomes

Purpose

To compare safety and efficacy of vascular plugs (VPs) and fibered platinum coils (FPCs) for embolization in pelvic congestion syndrome (PCS).

自拟中药汤剂联合湿润烧伤膏治疗湿热型带状疱疹的疗效观察

目的观察自拟中药汤剂与湿润烧伤膏联合治疗湿热型带状疱疹的临床效果。方法 将60例湿热型带状疱疹患者随机分为治疗组(30例)与对照组(30例)。治疗组给予口服自拟中药汤剂与外用湿润烧伤膏联合治疗;对照组给予口服自拟中药汤剂与外用阿昔洛韦乳膏联合治疗,观察两组治疗效果。结果治疗组总有效率为93.33%,对照组总有效率为53.34%,两组比较P0.05,差异有统计学意义。结论口服自拟中药汤剂与外用湿润烧伤膏联合治疗湿热型带状疱疹疗效较好,值得临床推广应用。
