Rare vertebro-vertbral fistula treatment

42yr / male presented with sudden onset weakness of right superior extremity.Weakness progressed rapidly to both superior extremities. K/C/O Neurofibromatosis. MRI and Digital subtraction angiography (DSA) demonstrated a very rare condition: Vertebro-vertebral fistula (VVF). The VVF was completely embolized (cured) by endovascular coiling with excellent recovery in power.

Double stent assisted coiling of a complex basilar top aneurysm-Video

Rupture of brain aneurysm (A balloon like swelling over a blood vessel) results in brain hemorrhage (Subarachnoid Hemorrhage- SAH). Patients present to the emergency with a complaints of "worst headache of their life." Treating the aneurysm in a patient of SAH if of paramount importance, as aneurysms are know to have very high risk of re-bleed leading to death of patients

High Intensity Focused Ultrasound In RSNA News

RSNA News, December 2007

"RESEARCHERS at Duke University Medical Center report using mechanical high-intensity focused ultrasound (HIFU) to activate the immune system to recognize and attack malignant tumors, pointing the way toward a whole new field in cancer therapy for radiologists. The study was detailed in the August 3, 2007, issue of the Journal of Translational Medicine."

Sounds like interventional Radiology is looking at new horizons yet unseen.

High intensity focused ultrasound (HIFU) is an emerging non-invasive treatment modality for localized treatment of cancers. While current clinical strategies employ HIFU exclusively for thermal ablation of the target sites, biological responses associated with both thermal and mechanical damage from focused ultrasound have not been thoroughly investigated. In particular, endogenous danger signals from HIFU-damaged tumor cells may trigger the activation of dendritic cells. This response may play a critical role in a HIFU-elicited anti-tumor immune response which can be harnessed for more effective treatment.
