Are Endovascular Interventions for Central Vein Obstructions due to Cardiac Implanted Electronic Devices Effective?

One of the late-onset complications of cardiac implanted electronic devices (CIEDs) is central venous obstruction (CVO). The aim of this study was to investigate the feasibility, efficacy, and safety of endovascular treatment of CIED-related CVOs. Eighteen patients who underwent endovascular management of their device-related CVO were reviewed.

Percutaneous intentional intra-luminal-assisted recanalization (PILAR technique) of challenging chronic total occlusions using a high-frequency vibration device.

Objectives: Recanalization of peripheral chronic total occlusions (CTO) is technically challenging especially in cases of in-stent and/or pre-stent and heavily calcified lesions. A high-frequency vibrational device (HFVD) was first used as a secondary-intention device in CTO recanalizations when they were refractory to a guidewire. The aim of this study was to assess the safety and efficacy of the HFVD as a first-line treatment for challenging CTOs and thus to define the percutaneous intentional intraluminal-assisted recanalization (PILAR) technique.

Target volume definition in high-risk prostate cancer patients using sentinel node SPECT/CT and 18 F-choline PET/CT.

Background: To assess the influence of sentinel lymph nodes (SNs) SPECT/CT and 18 F-choline (18 F-FCH) PET/CT in radiotherapy (RT) treatment planning for prostate cancer patients with a high-risk for lymph node (LN) involvement.

Methods: Twenty high-risk prostate cancer patients underwent a pelvic SPECT acquisition following a transrectal ultrasound guided injection of 99mTc-Nanocoll into the prostate. In all patients but one an 18 F-FCH PET/CT for RT treatment planning was performed.

Intracranial aneurysm stenting: follow-up with MR angiography.

Intracranial stenting is increasingly being used to treat intracranial aneurysms and stenoses. We wanted to assess the utility of magnetic resonance angiography (MRA) in the follow-up of patients treated with various types of intracranial stents and to assess the utility of performing gadolinium-enhanced MRA. A total of 19 patients having undergone intracranial stenting for aneurysms were imaged by MRI at 1.
