Article Abstract
Background: The arteriovenous (AV) loop is a versatile and reliable technique for establishing vascular access in head and neck free tissue reconstruction. This method is particularly advantageous in complex cases where conventional vascular access may be challenging.
Methods And Results: In this pictorial essay, we present the pre-operative planning and patient selection factors for creating AV loops, and artist-illustrated drawings detailing our intraoperative technique. This work provides the surgeon a guide to perform and understand the procedure of harvesting a vein graft, creating a loop, and appropriately positioning it in preparation for microsurgical repair.
Conclusion: The AV loop technique yields a reliable conduit, and its flexibility allows for complex free-flap reconstructions in challenging scenarios where vessels are not locally available or in situations where vessel length is inadequate.

The aim of this study was to grow axially vascularized soft tissue flaps in sheep using the arteriovenous loop (AVL) technique to be transplanted for defect reconstruction. This technique may be a promising alternative to conventional free flaps to further reduce flap donor site morbidity. In this pilot study, AVLs ( = 12) were created in the groins of six sheep, placed into an isolation chamber, and embedded in Matriderm®.

Rationale: As the end-stage kidney disease (ESKD) population requiring vascular access for hemodialysis continues to grow, the Kidney Disease Outcomes Quality Initiative guidelines emphasize vessel preservation to ensure viability for future access. Preoperative ultrasound is commonly performed prior to arteriovenous (AV) access creation when available. However, its major limitation is the restricted imaging range, which impedes visualization of the complete vascular network.

Transcatheter device closure of a large perimembranous ventricular septal defect with left-to-right shunt was attempted with an antegrade transvenous approach and a conventional arteriovenous loop facilitated, both of which were unsuccessful. We succeeded with an indigenous technique of advancing the delivery sheath towards the left ventricular apex from the venous side with the help of a cut pigtail, keeping the arteriovenous loop.

Extensive thoracic wall defects can arise from the resection of malignant tumours or from sternal osteomyelitis following cardiac surgery. The aim of this study is to analyse the feasibility of reconstruction with free flaps, and considers recipient vessel conditions, surgical complications, and reconstructive outcomes.In this bicentric retrospective clinical study, all patients who underwent free flap transplantation for the reconstruction of an extensive thoracic wall defect between January 2013 and September 2024 were included.
