Diagnostic yield of CT-guided lung biopsies: how can we limit negative sampling?

Objectives: To investigate whether lesion imaging features may condition the outcome of CT-guided lung biopsy (CTLB) and to develop a scoring system of biopsy outcome prediction.

Methods: This is a single center retrospective study on 319 CTLBs that were performed in 319 patients (167 males/152 females, mean age 68 ± 12.2).

Aspiration Thrombectomy with the Indigo System for Acute Lower Limb Ischemia: Preliminary experience and analysis of parameters affecting the outcome.

Background: The purpose of our study is to assess the short-term technical success and the safety of the Indigo System in a series of patients undergoing vacuum-assisted catheter direct thrombus aspiration (IS-CDTA) for acute lower limb ischemia (ALLI) and to evaluate which parameters may affect the outcome.

Methods: All procedures using the IS-CDTA for ALLI, performed in a single-centre Interventional Radiology Unit from February 2016 to March 2020, were retrospectively analysed. Technical success was defined as the achievement of nearly-complete or complete revascularization (TIPI grade 2/3) and considered as a good outcome.

Endovascular management of giant visceral artery aneurysms.

Endovascular management of small visceral artery aneurysms is an established treatment with satisfactory outcomes. However, when size exceeds 5 cm visceral aneurysms are considered as "giant" (giant visceral artery aneurysms or GVAAs) and management is significantly more complex. Between August 2007 and June 2019 eleven cases of GVAAs that were endovascularly treated were retrospectively reviewed and included in this single center study.

Techniques and future perspectives for the prevention and treatment of endoleaks after endovascular repair of abdominal aortic aneurysms.

The presence of endoleaks remains one of the main drawbacks of endovascular repair of abdominal aortic aneurysms leading to the increase of the size of the aneurysmal sac and in most of the cases to repeated interventions. A variety of devices and percutaneous techniques have been developed so far to prevent and treat this phenomenon, including sealing of the aneurysmal sac, endovascular embolisation, and direct sac puncture. The aim of this review is to analyse the indications, the effectiveness, and the future perspectives for the prevention and treatment of endoleaks after endovascular repair of abdominal aortic aneurysms.

FemoSeal vascular closure device for antegrade common femoral artery access: Safety and technical notes.

Purpose: To retrospectively assess the efficacy and safety of FemoSeal vascular closure device to achieve hemostasis following antegrade common femoral artery puncture after lower limb revascularization using vascular sheaths from 5 to 8 Fr.

Methods: We reviewed the hemostatic outcome achieved with FemoSeal in 103 consecutive patients (mean age: 69 ± 8 years, 71 males) that undergone to 111 antegrade common femoral artery accesses for percutaneous lower limbs revascularization using 5- to 8-Fr vascular sheaths. We used FemoSeal in an unselected population, without exclusion criteria.

Postoperative ascending aortic gigantic pseudoaneurysm: Endovascular treatment with the use of a septal occluder plug.

A rare postoperative complication of aortic root replacement is pseudoaneurysm formation. Surgical repair may be rather challenging particularly in patients who are elder and with significant comorbidities. Endovascular approach may also be technically demanding, given the high blood velocity and the anatomical challenges of the area of the aortic root and the ascending aorta.

Wide-neck renal artery aneurysm: parenchymal sparing endovascular treatment with a new device.

Background: Renal artery aneurysm is a rare disorder with a high mortality rate in the event of rupture, the most frequent complication, which can also occur in lesions smaller than those indicated for treatment by current criteria. Surgery is still the first-line treatment, although a growing trend toward endovascular management of visceral artery aneurysms has emerged because of the high efficacy and low invasiveness that has been demonstrated by several authors. Treatment of wide-necked aneurysms and, depending on location, those at renal artery bifurcations or distal branches is more complex and may require invasive surgical techniques, such as bench surgery.
