Review Case Reports
Ruptured Iliac Pseudoaneurysm after Intravesical Bacillus Calmette-Guérin: Urgent Endovascular Treatment. Case Report and Literature Review.
Ruptured mycotic aneurysms are an extremely rare complication of intravesical Bacillus Calmette-Guerin (BCG) immunotherapy. Several cases involving various arterial sites, mostly in the thoracic or abdominal aorta, have been described in the literature. BCG immunotherapy rarely causes false aneurysms and open surgical repair using an in situ prosthetic graft is most commonly performed. Further to this, targeted antituberculous treatment is required for at least one year following surgery. ⋯ Endovascular repair can be considered a valid option in an emergency. A hybrid approach was chosen due to the need for urgent action and the poor condition of the patient who was hemodynamically unstable. In particular, the implantation of an aortouniiliac endoprosthesis at the level of the contralateral iliac axis allowed us to avoid the release of an endoprosthesis at the infected area level. Close patient follow-up with clinical evaluation every 3 months and a computed tomography scan yearly is mandatory following the intervention and during antibiotic therapy. A systematic review of the literature has been subsequently carried out on this specific clinical case, highlighting 47 cases described from 1988.

Three-dimensional (3D) printing, also known as rapid prototyping or additive manufacturing, is a novel adjunct in the medical field. The aim of this systematic review is to evaluate the role of 3D printing technology in the field of contemporary vascular surgery in terms of its technical aspect, practicability, and clinical outcome. ⋯ 3D printing was recognized and gradually incorporated as a useful adjunct in the field of vascular and endovascular surgery. The production of an accurate anatomic patient-specific replica was shown to bring significant impact in patient management in terms of anatomic understanding, procedural planning, and intraoperative navigation, education, and academic research as well as patient communication. Further analysis on cost-effectiveness was indicated to guide decisions on applicability of such promising technology on a routine basis.
