Detection of renal artery pseudo-aneurysm six months after robotic assisted partial nephrectomy in a patient whose only complaint was flank pain.

Urol Case Rep 2020 Nov 24;33:101259. Epub 2020 May 24.

Division of Urology, Department of Surgery, University of Pennsylvania Health System, Philadelphia, PA, USA.

Renal artery pseudoaneurysm (RAP) is a potentially life-threatening complication after partial nephrectomy (PN). Studies suggests that most cases present within 15 days post operatively with one of three classic symptoms: gross hematuria, flank pain and/or anemia. However, there are a limited number of reports in the literature regarding delayed RAP (≥four months). Read More

Atypical renal artery preservation with an iliac branch device in an infrarenal abdominal aortic aneurysm.

Ann Vasc Surg 2020 May 27. Epub 2020 May 27.

Department of Endovascular Therapy, Hospiten Rambla, Santa Cruz de Tenerife, Tenerife, Canary Islands, ES; Department of Medical Science and Surgery, University of Las Palmas de Gran Canaria, Las Palmas de Gran Canaria, Canarias, ES.

Anatomical variations of the renal arteries may complicate endovascular repair of infrarenal abdominal aortic aneurysms (AAA). Occlusion of renal branches may be necessary to seal the aneurysm sac efficiently. Depending on the size of the affected renal arteries and the supplied parenchyma, this can lead to loss of renal function. Read More

Patient radiation dose from x-ray guided endovascular aneurysm repair: A Monte Carlo approach using voxel phantoms and detailed exposure information.

J Radiol Prot 2020 May 19. Epub 2020 May 19.

Academic Department of Vascular Surgery, School of Cardiovascular Medicine and Sciences, BHF Centre of Excellence at Guy's and St Thomas' NHS Foundation Trust, King's College London, London, London, UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND.

Endovascular aneurysm repair (EVAR) is a well-established minimally invasive technique that relies on x-ray guidance to introduce a stent through the femoral artery and manipulate it into place. The aim of this study was to estimate patient organ doses from EVAR procedures using anatomically realistic computational phantoms and detailed exposure information from radiation dose structured reports (RDSR). Methods: Lookup tables of conversion factors relating kerma area product (PKA) to organ doses for 49 different beam angles were produced using Monte Carlo simulations (MCNPX2. Read More

Maximizing Proximal Seal Zone in Fenestrated Endografting: Evolution in the Approach to Graft Configuration.

J Vasc Surg 2020 Apr 21. Epub 2020 Apr 21.

University of Pennsylvania, Philadelphia, PA, United States.

Objectives: Fenestrated endografting for juxta- and para-renal abdominal aortic aneurysms (AAA) affords the ability to seal stent grafts in normal aorta at and above the renal arteries. The Zenith fenestrated graft (ZFEN, Cook Medical, Bloomington, IN) is custom-made to surgeon specification, subject to certain manufacturing limitations. The most common configuration in the pivotal trial and in post-approval commercial use has been a scallop for the superior mesenteric artery (SMA) and two small fenestrations for the renal arteries (configuration "A").

Allograft artery mycotic aneurysm after kidney transplantation: A case report and review of literature.

World J Clin Cases 2020 Mar;8(5):912-921

Renal Transplantation, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan 20122, Italy.

Background: Allograft artery mycotic aneurysm (MA) represents a rare but life-threatening complication of kidney transplantation. Graftectomy is widely considered the safest option. Due to the rarity of the disease and the substantial risk of fatal consequences, experience with conservative strategies is limited. Read More

Microcatheter injection reduces the amount of contrast medium during middle cerebral artery aneurysm embolization in a patient with chronic kidney disease.

Radiol Case Rep 2020 May 6;15(5):542-544. Epub 2020 Mar 6.

Department of Neurosurgery, Kobe University Graduate School of Medicine, 7-5-1, Kusunoki-cho, Chuo-ku, Kobe 650-0017, Japan.

We describe a unique technique to reduce the amount of contrast medium by injecting diluted contrast medium from the microcatheter during neurointervention. A patient with severe renal impairment due to polycystic kidney was referred for endovascular surgery for wide-neck middle cerebral artery aneurysm. In order to reduce the amount of contrast medium, contrast medium was injected from the microcatheter placed in the middle cerebral artery during coil embolization; renal function decline was not observed after the procedure.

Geometric and hemodynamic analysis of fenestrated and multibranched aortic endografts.

J Vasc Surg 2020 Mar 12. Epub 2020 Mar 12.

Department of Angiology and Vascular Surgery, Hospital Clínico Universitario de Valladolid, Valladolid, Spain.

Objective: The objective of this study was to determine the influence of hemodynamic force on the development of type III endoleak and branch thrombosis after complex endovascular thoracoabdominal aortic aneurysm repair.

Methods: Patients with thoracoabdominal aortic aneurysm, within surgical range, treated with a fenestrated or branched endovascular aneurysm repair from 2014 to 2018 and with 3-month control computed tomography angiography were selected. Demographic variables, aneurysm anatomy, and endograft conformation were analyzed retrospectively from a prospective registry. Read More

Endovascular repair of an abdominal aortic aneurysm associated with crossed fused renal ectopia.

J Vasc Surg Cases Innov Tech 2020 Mar 3;6(1):140-142. Epub 2020 Mar 3.

Department of Vascular and Endovascular Surgery, General Regional Hospital Ente Ecclesiastico "F.Miulli", Acquaviva delle Fonti, Italy.

Chimney/snorkel endovascular aneurysm repair (Ch-EVAR) enables the minimally invasive treatment of abdominal aortic aneurysm in anatomically challenging and high-risk surgical cases. Here, we present the case of a 77-year-old man with an abdominal aortic aneurysm associated with crossed fused renal ectopia and an ectopic renal artery arising directly from the aneurysm sac. After successful implementation of Ch-EVAR, computed tomography angiography at 18 months revealed no endoleaks, patency of the parallel graft, and normal renal vascularization and function.

Systematic and Multidisciplinary Evaluation of Fibromuscular Dysplasia Patients Reveals High Prevalence of Previously Undetected Fibromuscular Dysplasia Lesions and Affects Clinical Decisions: The ARCADIA-POL Study.

Hypertension 2020 Apr 9;75(4):1102-1109. Epub 2020 Mar 9.

From the Departments of Hypertension (E.W.-C., A.P., P.D., E.F., K.J.-P., M.K., M.P., K.H., P.T., M.S., K.K., A.J.), Institute of Cardiology, Warsaw, Poland.

Fibromuscular dysplasia (FMD), regarded as a generalized vascular disease, may affect all vascular beds and may result in arterial stenosis, occlusion, aneurysm, or dissection. It has been proposed to systematically evaluate all vascular beds in patients with FMD, regardless of initial FMD involvement. However, the impact of this approach on clinical decisions and on management is unknown. Read More

Niger J Clin Pract 2020 Mar;23(3):310-314

Department of Radiology, Federal Medical Centre, Owerri, Imo State, Nigeria.

Background: The abdominal aorta is the largest artery in the human body. Sonographic assessment of the abdominal aortic diameter is presently the preferred screening method for an aortic aneurysm. However, there are no customized nomograms for our population and the recommended cutoffs for screening may be inappropriate. Read More

Brain Sci 2020 Feb 27;10(3). Epub 2020 Feb 27.

Department of Neurosurgery, 5001 Kantonsspital Aarau, Switzerland.

Intracranial aneurysms (IA) are characterized by weakened cerebral vessel walls that may lead to rupture and subarachnoid hemorrhage. The mechanisms behind their formation and progression are yet unclear and warrant preclinical studies. This systematic review aims to provide a comprehensive, systematic overview of available animal models for the study of IA pathobiology. Read More
