Background: The trans femoral ipsilateral approach is often adopted for endovascular treatment (EVT) for better steerability of guidewires or better device deliverability. However, contrary to the trans femoral contralateral approach, ipsilateral antegrade puncture sometimes causes peculiar bleeding complications., Case Presentation: A 76-year-old female underwent EVT for chronic occlusion of the left superficial femoral artery (SFA) via the ipsilateral antegrade approach. After guidewire passage, we inflated the drug-coated balloons, but angiography showed blood flow stasis at the mid segment of the SFA. We also ensured prolonged balloon inflation, which resulted in favorable blood flow. While trying to ensure hemostasis, the blood pressure remained decreased, but neither bleeding nor superficial hematoma were observed at the puncture site. After hemostasis was achieved, we removed the surgical drape and noticed a swelling in the mid-portion of the thigh, distant from the puncture point. We then approached the left common femoral artery (CFA) contralaterally. Angiography showed continuous bleeding from a little bit distally to the sheath insertion point that was spreading through an intramuscular space. We stopped the bleeding with balloon tamponade inside the CFA. Angiography after hemostasis demonstrated blood flow stasis at the mid-segment of the SFA, similarly as that seen before. We confirmed compression of the SFA by a large hematoma using both intra- and extra- vascular ultrasound. Therefore, we deployed a self-expandable stent at the compressed SFA position. Finally, we achieved favorable blood flow on angiography., Conclusion: We encountered a case that latent bleeding unrecognized in the surgical field persisted while prolonged inflation of DCB was conducted at just proximal SFA. We could have avoided bailout stenting by noticing the bleeding incident in a timely manner. Prediction and prevention are essential for all kinds of procedural complications in EVT., (© 2024.

Background: Vascular closure devices have been widely used to achieve rapid hemostasis after percutaneous catheterization procedures via the common femoral artery. The EXOSEAL vascular closure device is a device that can deliver a bioabsorbable polyglycolic acid plug to fill the subcutaneous puncture route at the groin for rapid hemostasis, and this device has a lower risk of arterial occlusion than other vascular closure devices., Case Presentation: An 83-year-old Japanese man underwent percutaneous coronary intervention for a proximal stenosis in his left circumflex artery through a 7-Fr sheath from his right common femoral artery. We encountered acute popliteal artery occlusion associated with EXOSEAL vascular closure device. We detected the plug material of this device at the occluded lesion by intravascular ultrasound, and performed successful bailout stenting after pulling the embolus with an inflated balloon catheter up to the superficial femoral artery from the popliteal artery., Conclusion: Acute limb ischemia caused by an EXOSEAL vascular closure device is a very rare complication. Balloon angioplasty and stenting are considered to be effective options to deal with the plug dislodgement of an EXOSEAL vascular closure device. We must be prepared for every rare complication during endovascular treatment.
