Mechanical Thrombectomy for Stroke: How Stent Retrievers and Aspiration Work
For a large-vessel stroke, mechanical thrombectomy physically removes the clot from a brain artery — one of the biggest advances in stroke care. How stent retrievers and aspiration work, and why time is brain.
Read guidePulmonary Embolism Management
Pulmonary Embolectomy and Catheter-Based PE Treatment
When a pulmonary embolism is large or unstable, the clot may need to be removed rather than just thinned. This guide covers catheter aspiration thrombectomy, surgical embolectomy, and how PE risk drives the choice.
Read guideDeep Vein Thrombosis (DVT)
Catheter-Directed Thrombolysis (and EKOS-Type Therapy) for DVT and PE
Catheter-directed thrombolysis delivers a clot-dissolving drug straight into a large clot through a catheter, sometimes assisted by ultrasound. How it works for DVT and pulmonary embolism, and how it compares with systemic drugs.

Drug-Coated Balloon vs Drug-Eluting Stent: How Physicians Choose
Drug-coated balloons and drug-eluting stents both deliver an anti-restenotic drug to a treated artery — but one leaves an implant behind and one does not. How the two compare and when each is preferred.

ECMO Cannulation: VV vs VA Configurations, Cannula Selection, and Decannulation
ECMO cannulation establishes the vascular access that makes extracorporeal life support possible. This guide covers VV vs VA configurations, cannula selection, and decannulation.

Renal Denervation: Catheter-Based Treatment for Resistant Hypertension
Renal denervation ablates overactive sympathetic nerves along the renal arteries to lower blood pressure that resists medication. Mechanism, evidence arc, procedure, and device considerations.
Read guideAortic Aneurysm & Dissection Repair
TEVAR (Thoracic Endovascular Aortic Repair): Procedure, Indications, and Devices
TEVAR repairs aneurysms and dissections of the descending thoracic aorta with a stent graft delivered through the femoral arteries — no open chest surgery. Indications, procedure steps, devices, and follow-up.

Microcatheters Explained: Hubs, Steerable Sheaths, and Deflectable Catheters
A practical guide to microcatheter anatomy — including the microcatheter hub — and how steerable sheaths and deflectable catheters differ, with selection criteria for neurovascular and peripheral intervention.

VenaBLOCK vs VenaSeal: Comparing Cyanoacrylate Vein Closure Systems
An evidence-linked comparison of the two dedicated cyanoacrylate closure systems for varicose veins — VenaBLOCK (INVAMED) and VenaSeal (Medtronic) — covering mechanism, delivery, and published studies.

EVAR (Endovascular Aneurysm Repair): Meaning, Procedure, and Devices
EVAR stands for endovascular aneurysm repair — a minimally invasive procedure that excludes an aortic aneurysm from circulation using a stent graft delivered through the femoral arteries.

Transarterial Chemoembolization for Hepatocellular Carcinoma: Conventional vs Drug-Eluting Bead Techniques
Transarterial chemoembolization (TACE) is an image-guided, catheter-based therapy for hepatocellular carcinoma in which chemotherapy is delivered directly into the hepatic artery branches feeding the tumor, followed by…

Endovenous Ablation Vs Surgical Stripping For Varicose Veins Comparative Outcomes And Patient Selection
Varicose veins arise from chronic venous insufficiency, in which failure of the one-way valves inside the superficial veins allows blood to reflux and pool against gravity. Persistent venous…

Dural Arteriovenous Fistula Embolization Transarterial Vs Transvenous Approaches
Embolization deliberately occludes a target vessel to control bleeding, devascularize a tumor, or treat a vascular malformation. Agent selection — coils, plugs, particles, or liquid embolics — is…
