Avoiding Aortic Valve Passage in Branched Arch Repair by Use of the Modified Balloon Nose Cone Technique.
J Endovasc Ther
November 2024
Department of Vascular Surgery, University Hospital Regensburg, Regensburg, Germany.
Purpose: To demonstrate the Modified Balloon Nose Cone Technique to avoid passage of the aortic valve in endovascular branched arch repair.
Technique: The technique is demonstrated in a 54-year-old patient after previous open repair of the ascending aorta and mechanical aortic valve replacement due to type A aortic dissection. The delivery system of a custom-made stent-graft with 3 inner branches was modified by subtotally sawing off its nose cone.
Efficacy and safety of the needle rendezvous technique for infrainguinal arterial calcified lesions.

Background: Lower extremity artery disease is increasingly prevalent, and complex lesions such as calcified chronic total occlusions pose significant challenges during endovascular therapy. The needle rendezvous technique, which involves puncturing a needle toward the guidewire within the lesion or lumen and advancing the guidewire into the needle lumen to achieve guidewire externalization, offers a potential solution. If device passage remains challenging, the Rendezvous-PIERCE technique can be subsequently employed by advancing the needle over the externalized guidewire to modify the lesion directly.

Methods And Results: Thirteen consecutive patients (6 females, average age 67.7 years) with a mean left ventricular ejection fraction of 60%, a median STS score of 3.
Rendezvous-PIERCE technique: establishing a channel through severe calcification in infrainguinal arterial lesions using needle rendezvous.

Department of Cardiology, Asia Medical Group, Sapporo Heart Center, Sapporo Cardio Vascular Clinic, North 49, East 16, 8-1, Higashi Ward, Sapporo City, Hokkaido, 007-0849, Japan.
Background: Severe calcification often prevents device passage and balloon expansion in cases of lower extremity artery disease. To address this limitation, we introduced a novel calcium modification technique called Rendezvous-PIERCE (R-PIERCE).
Methods: A needle was inserted in a retrograde manner and advanced to touch the tip of an antegrade guidewire within the lesion.
Analysis of the Effectiveness of Second Attempt Endoscopic Retrograde Cholangiopancreatography (ERCP) 24 Hours (Second Day) After Primary Failure.

Gastroenterology, Lady Reading Hospital, Peshawar, PAK.
Background: Endoscopic retrograde cholangiopancreatography (ERCP) is a minimally invasive intervention that has established itself as the gold standard therapeutic option for various pancreaticobiliary conditions. Deep cannulation of the common bile duct (CBD) is essential in ERCP. However, cannulation is not possible in approximately 20% of the cases with the usual techniques even when performed by highly trained professionals or at major healthcare institutions.
