Abstract

We are presenting a case of a patient who developed a pseudoaneurysm following cardiac catheterization. This is one of the most common complications related to invasive cardiovascular procedures. A pseudoaneurysm forms when an arterial puncture site fails to seal, allowing blood to leak and form a pulsatile hematoma contained by fibromuscular tissues. Color Doppler imaging has been the investigative method of choice for this diagnosis, which demonstrates swirling flow in a mass connected to the parent artery in the neck. The pseudoaneurysm neck shows "to and fro" Doppler waveforms. The treatment options for pseudoaneurysms include ultrasound (US)-guided compression, minimally invasive percutaneous treatments including US-guided thrombin injection, coil embolization and covered stent placement, and open surgical treatment. All of these treatment options have their own advantages and disadvantages, which will be discussed in detail.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
