Prophylactic Uterine Artery Embolization in Placenta Accreta Spectrum-An Active Intervention to Reduce Morbidity and Promote Uterine Preservation.

Purpose: To evaluate the feasibility and safety of early and proactive involvement of interventional radiology (IR) in the management of placenta accreta spectrum (PAS) by performing the cesarean operation and prophylactic uterine artery embolization in the IR angiography suite as a combined procedure.

Materials And Methods: This study evaluated the effectiveness and safety of prophylactic uterine artery embolization prior to placental separation in cases of antenatally proven or suspected abnormal placentation. Over a 5-year period, 16 consecutive patients with PAS underwent combined IR and obstetric intervention.

Evaluation of a noise reduction imaging technology in iliac digital subtraction angiography: noninferior clinical image quality with lower patient and scatter dose.

Purpose: To determine whether equivalent-quality images can be obtained from digital subtraction angiography (DSA) of the iliac artery after implementation of a novel imaging technology that reduces patient and scatter x-ray dose.

Materials And Methods: Imaging using two randomly ordered DSA runs was performed in 51 adults scheduled for iliac artery angiography or intervention or both. One DSA run used standard acquisition chain and image processing algorithms (referred to as " reference DSA"), and the other DSA run used dose-reduction and real-time advanced image noise reduction technology (referred to as "study DSA").

Long-term follow-up of treatment of pulmonary arteriovenous malformations with AMPLATZER Vascular Plug and AMPLATZER Vascular Plug II devices.

Purpose: To assess the feasibility, complications, and long-term success of embolization of pulmonary arteriovenous malformations (PAVMs) with the AMPLATZER Vascular Plug and AMPLATZER Vascular Plug II.

Materials And Methods: The study included 15 consecutive patients (19 embolization episodes) who had embolization of PAVMs between April 2004 and April 2009 with an AMPLATZER Vascular Plug or AMPLATZER Vascular Plug II. There were 4 men and 11 women, with a mean age of 56 years (range 24-74 years).

Three-year follow-up of fenestrated thoracoabdominal stent graft bridging an endovascular thoracic stent graft and a surgical abdominal aortic graft.

This case report describes repair of a type I endoleak at the distal landing zone of a thoracic aortic stent graft by endovascular placement of a thoracoabdominal fenestrated stent graft (Cook, Brisbane, Australia). The fenestrated stent graft was interposed between a previous abdominal aortic aneurysm (AAA) Gelsoft tube graft (Sulzer Vascutek Ltd, Inchinnan, United Kingdom) and two overlapping Zenith thoracic endografts (Cook Inc, Bloomington, Indiana). Placement was made more complex because the distal thoracic endograft had rotated into a horizontal position.

Long-term outcomes of low-dose catheter-directed thrombolytic therapy: a 5-year single-center experience.

Purpose: To determine immediate and long-term outcomes following catheter-directed intraarterial thrombolysis of occluded native arteries and infrainguinal vein grafts by using low-dose tissue-type plasminogen activator (tPA) in patients with lower limb ischemia.

Materials And Methods: One hundred eleven intraarterial thrombolysis procedures were performed in 96 patients during the 2-year study period. Patient records were available for retrospective review in 85 thrombolytic procedures performed in 74 (77%) of the 96 patients.

Carotid stump syndrome: pathophysiology and endovascular treatment options.

Carotid stump syndrome is one of the recognised causes of recurrent ipsilateral cerebrovascular events after occlusion of the internal carotid artery. It is believed that microemboli arising from the stump of the occluded internal carotid artery or the ipsilateral external carotid artery can pass into the middle cerebral artery circulation as a result of patent external carotid-internal carotid anastomotic channels. Different pathophysiologic causes of this syndrome and endovascular options for treatment are discussed.

Popliteal venous aneurysm: a rare cause of recurrent pulmonary emboli and limb swelling.

Popliteal venous aneurysm is a rare cause of recurrent pulmonary embolism, although the true incidence of aneurysm is probably underestimated. One-third of patients suffer further embolic events despite therapeutic anticoagulation. We report the case of a 59-year-old male who presented with recurrent PEs over a period of 12 years despite anticoagulation therapy.
