Article Abstract
Background: Iatrogenic femoral artery pseudoaneurysms are a recognized complication after catheterization procedures. Although ultrasound-guided thrombin injection is the mainstay of treatment, pseudoaneurysms with wide necks or complex anatomy pose treatment challenges.
Case Summary: We present a 6-case series in which a modified balloon-assisted thrombin injection (BATI) technique was employed using retrograde pedal or anterograde radial access in iatrogenic femoral artery pseudoaneurysms with wide-neck morphology or procedural risk factors. Distal access permitted simultaneous angiographic visualization and balloon occlusion during thrombin injection. All patients achieved complete thrombosis without complications or recurrence over 6 to 9 months of follow-up.
Conclusions: Modified BATI via distal access offers a minimally invasive alternative for select complex pseudoaneurysms when traditional approaches are less favorable. Future studies are needed to evaluate long-term outcomes.

Introduction And Importance: Anastomotic aortic pseudoaneurysm is a rare, late, and fatal complication after open surgery to repair an abdominal aneurysm. Treatment can be challenging in complex cases, especially renal and visceral arteries. A common solution is the fenestrated endograft, which has branches that accommodate these vital vessels.

Transcaval Transcatheter Aortic Valve Replacement: Clinical Outcomes From a TAVI Program Without Prior Transcaval Experience.

Department of Cardiology, Mater Misericordiae University Hospital, Dublin, Ireland.
Background: Despite the emergence of the transcaval (TCv) access route for transcatheter aortic valve implantation (TAVI) in the treatment of patients with hostile iliofemoral anatomy, the number of patients reported in clinical series of TCv TAVI has been relatively small (< 500 published cases). We assessed procedural and clinical outcomes in a prospective cohort of patients undergoing TAVI using TCv access at a clinical site without prior TCv TAVI experience.
Methods: A prospective TAVI database was used to identify all patients treated with TCv TAVI at our center.
A Novel Non-Surgical Treatment for Iatrogenic Radial Artery Pseudoaneurysm: A Case Series.

Background: Iatrogenic radial artery pseudoaneurysm (iRAP) is a rare but potentially devastating complication after transradial access. Spontaneous thrombosis rarely occurs in lesions > 2 cm in size, surgery is invasive, and USG-guided thrombin injection risks distal embolisation due to the short necks of most iRAP.
Aims: We describe a non-surgical approach by Differential Radial Artery Isolation and NEedle Decompression (DRAINED) for treating iRAP.

Metastasis, a major complication in cancer, is known to depend on the interaction of tumor cells with platelets. However, anti-platelet therapy does not reliably increase survival rates. To address this, here we use light transmission aggregometry, flow cytometry, and confocal microscopy for characterization of human platelets interaction with six lines of tumor cell cultures.
