A stent fracture (SF) is one of the responsible factors for in-stent restenosis after a percutaneous coronary intervention. Factors that have an important role for a SF are vessel tortuosity, the presence of a right coronary artery lesion, overlapping stents, and the use of a drugeluting stent (DES) such as a sirolimus-eluting stent. Unlike with the use of bare metal stents, most SFs have occurred with the use of DES, and a DES may be a possible factor for a SF. A SF can cause clinical problems that range from stable angina to acute coronary syndrome. We experienced a case of acute myocardial infarction that was combined with a SF. We describe here the coronary angiography findings and the 64-multidetector computed tomography images before and after the SF.

Percutaneous coronary intervention of a severely calcified coronary artery stenosis is associated with stent underexpansion and adverse outcomes. Intravascular lithotripsy (IVL) is a novel technology for fracturing calcified plaque in the coronary artery. We describe the first case of a severely calcified, undilatable coronary artery lesion.

We report a rare case of a missed intracavernous internal carotid artery dissecting aneurysm occurring as a complication of the base of skull fracture with severe brain injury causing acute cavernous sinus syndrome with permanent vision loss. A 31-year-old Myanmar lady had an alleged motor vehicle accident and suffered severe traumatic brain injury with multiple intracranial bleeds, multiple facial bone and base of skull fractures, and limb fractures. At one week post-trauma, she had severe right eye proptosis with vision loss, ophthalmoplegia, chemosis, and high intraocular pressure.

Article Synopsis
- Heavily calcified coronary artery disease complicates percutaneous coronary intervention (PCI), requiring advanced techniques like cutting balloons (CB), which need standardization for better effectiveness.
- The study presents the RODIN-CUT technique, which involves sequential CB inflations guided by intravascular ultrasound (IVUS) to improve plaque modification and stent expansion in difficult cases.
- Results indicate that RODIN-CUT achieved high procedural success rates and minimal complications, suggesting it could be a simple and cost-effective method for treating calcified lesions, though larger studies are needed to confirm its validity.
Repeated Supera stent fracture following stenting for popliteal artery occlusion: a case report.

The popliteal artery segment is particularly challenging for endovascular treatment. Stents used for treating popliteal artery lesions are usually associated with an increased risk of stent fracture and re-occlusion. The Supera stent is designed to withstand mechanical stress, with a low risk of fracture.
