Technique of Percutaneous Direct Needle Puncture of Calcified Plaque in the Superficial Femoral Artery or Tibial Artery to Facilitate Balloon Catheter Passage and Balloon Dilation of Calcified Lesions
“…Ichihashi et al reported the PIERCE technique. 4 This technique is a novel plaque modification from outside of the vessels. After the guidewire crossing, the severely calcified plaque was punctured from the outside of the vessels using a 19 to 16-G puncture needle.…”
A severely calcified lesion is the most challenging entity in endovascular therapy (EVT) for below-the-knee (BTK) arteries. In this report, we introduce a challenging plaque modification technique known as the inner PIERCE technique. A 65-year-old man on hemodialysis with multiple toe ulcerations underwent an EVT for his BTK artery diseases. During EVT, the guidewire passed through the severely calcified posterior tibial and plantar arteries; however, the other devices could not pass through the lesion. Therefore, a novel inner PIERCE technique was performed. After guidewire externalization, an 18G 20 cm needle was advanced from the retrograde approach site, following the guidewire, for percutaneous transhepatic cholangiodrainage (PTCD). The PTCD needle was advanced into the severely calcified plaque using a rotational motion. Finally, the needle could pass through the lesion. After the inner PIERCE technique, an angioplasty was performed with a 2.5 mm balloon. The final angiography showed sufficient blood flow. After the EVT, complete wound healing was achieved in 4 months. This challenging technique may be an additional option for EVT to treat severely calcified BTK arteries.

“…The direct plaque puncture technique (PIERCE technique) is reported as a low‐cost strategy that effectively facilitates device passage through severely calcified lesions . It involves percutaneous needle puncture of a severely calcified vessel to modify the lesion and allow balloon dilation.…”
“…The PIERCE technique 4 was performed when the balloon was unable to cross the lesion or when recoil could not be treated by a high-pressure noncompliant balloon. This was performed with 16-gauge needles.…”

“…3 Heavily calcified lesions are difficult to cross and are a hurdle to optimal dilation. 1 Ichihashi et al 4 developed a technique of percutaneous direct needle puncture of calcified plaque (PIERCE). In this technique, the calcified lesion is percutaneously punctured with a needle, causing a crack in the lesion to facilitate the passage of the device through the lesion.…”

“…In this technique, the calcified lesion is percutaneously punctured with a needle, causing a crack in the lesion to facilitate the passage of the device through the lesion. 4 It is a simple and inexpensive technique but is not always successful, partly because of mobility of the vessel. We developed a novel extension of the PIERCE technique that we termed the direct extravascular calcium interruption arterial procedure (DECIAP).…”
Severely calcified lesions continue to plague endovascular interventions by negatively affecting the acute and long-term results. A new technique was developed to allow balloon crossing or to treat persistent recoil. In the direct extravascular calcium interruption arterial procedure technique, an artery forceps is percutaneously introduced to modify the plaque after conventional techniques have failed. In this initial experience, the direct extravascular calcium interruption arterial procedure technique was successful as a bailout option in patients in whom balloon crossing was impossible or recoil was untreatable even with high-pressure balloons.
