Transradial approach has become preferable to conventional femoral artery access for both diagnostic coronary angiography and percutaneous coronary intervention. A rare but recognizable complication of radial access is radial artery pseudoaneurysm (RAp), which represents a potentially catastrophic complication. Treatment options comprise ultrasound (USG)-guided manual compression or thrombin injection or surgical correction. In this case series, we report four cases of RAps that we encountered at a single tertiary care center from July 2015 to January 2018. We compressed the radial artery using a sphygmomanometer cuff differentially rather than a TR band proximal to the pseudoaneurysm to treat three of them. One of the patients underwent surgical repair of the pseudoaneurysm as the location of the aneurysm was not suitable for compression or thrombin injection. In our series of cases, we conclude that RAp, a rare complication of radial catheterization, was seen more commonly in elderly female patients and can be easily treated by the USG-guided differential compression, a simple and readily available method. Prevention and early diagnosis is the key to avoid serious consequences.

BACKGROUND Early evidences on percutaneous coronary intervention with absorb bioresorbable scaffold (BRS) of small coronary vessels has been matter of concern. Accordingly, we aimed to assess the interplay between Absorb and small vessel disease (SVD) by the use of a large multicentre Italian registry.

In-stent restenosis (ISR) is a critical drawback of coronary stents, although initially described as benign, guidelines both support the use of intravascular imaging in the diagnosis and treatment of stent failure (Class IIa); however, our case highlights the limitation of optical coherence tomography in the assessment of the ISR (stent failure), it also highlights the association of self-limited severe acute respiratory syndrome coronavirus-2 illness and an acute coronary syndrome ISR presentation.
