Our aim was to describe the technique and clinical results of preoperative embolization of cervical spine osteoblastomas. We treated 3 patients with these tumors with transarterial embolization and subsequent surgical excision. In all 3 patients, distal access to the tumor-supplying vessels was gained with a microcatheter and embolization was performed with polyvinyl alcohol particles. No compl...

Preoperative splenic artery embolization for massive splenomegaly has been shown to reduce intraoperative hemorrhage during splenectomy. We describe a case of tumor lysis syndrome after proximal splenic artery embolization in a patient with advanced mantle cell lymphoma and splenic involvement. The patient presented initially with hyperkalemia two days after embolization that worsened during sp...

We recorded blood pressures in feeding arteries of cerebral arteriovenous malformations with microcatheters before, during, and after embolization in awake patients. Our embolization results corroborate reports of intraoperative measurements that show an immediate increase in blood pressure after ligation. Demonstration of abrupt hemodynamic changes gives additional credence to the theory of no...

Tumor rupture with hemorrhage is a severe complication of renal angiomyolipoma. Urgent transcatheter arterial embolization is an effective method for the patient suffering from life-threatening hemorrhage due to ruptured angiomyolipoma. Elective surgery has been suggested because of the possibility of rebleeding or abscess formation after embolization. However, it is not easy to perform a nephr...

background: central venous catheters (cvcs) have been used widely in clinics. these catheters are also recommended for children and infants receiving chemotherapy and total parenteral nutrition (tpn) and etc. in this paper, we present migrated fractured control line of the heart of a girl. case presentation: a 2.5 year old girl with migrated of the fractured central line into the heart. in the ...

Preoperative embolization procedures are constantly evolving and allow the performance of, or improve the outcome of, subsequent surgical interventions. Currently, some of the more frequently performed procedures in this group are portal vein embolization (PVE) in anticipation of extended liver resection, preoperative embolization of hypervascular tumors, and chemoembolization of hepatocellular...

We report the usefulness of Guglielmi detachable coil (GDC) embolization by direct carotid puncture for anterior circulation aneurysms. For all 27 patients, GDC embolization by direct carotid puncture was safely performed by using a 5F sheath introducer 5 cm long and a Tracker-38 catheter. Neurologic deficits and hemorrhage were not found in any patient during the follow-up period. If the trans...

In addition to imaging the lymphatics and detecting various types of lymphatic leakage, lymphangiography is a therapeutic option for patients with chylothorax, chylous ascites, and lymphatic fistula. Percutaneous thoracic duct embolization, transabdominal catheterization of the cisterna chyli or thoracic duct, and subsequent embolization of the thoracic duct is an alternative to surgical ligati...

Percutaneous transvenous embolization is one of the most effective treatments of intracranial dural arteriovenous fistulas (AVFs) involving the dural sinuses. We present a unique case of surgical transvenous embolization in a 48-year-old man with a dural AVF of the cavernous sinus who presented with intracerebral hematoma. The dural AVF drained only into the vein of the sylvian fissure on angio...

RATIONALE Orbital compartment syndrome (OCS) is a rare occurrence after transvenous embolization of indirect carotid-cavernous fistula (CCF). A lateral canthotomy and cantholysis are the most commonly performed surgical interventions. In our case, as the acute OCS occurred immediately after an uneventful transvenous embolization, an orbital floor orbitectomy was performed. PATIENT CONCERNS He...
