First-in-Human Clinical Application of the Medyria TrackCath System in Endovascular Repair of Complex Aortic Aneurysms (ACCESS Trial): A Prospective Multicenter Single-Arm Clinical Trial.

Purpose: The Medyria TrackCath Catheter (MedTCC) is an innovative, thermal convection-based blood flow velocity (BFV) tracking catheter that may be used during complex aortic endovascular procedures for identification and catheterization of target orifices. The ACCESS Trial analyzes the safety and performance of the MedTCC for targeted vessel catheterization to generally evaluate the feasibility of thermal convection-based BFV.

Materials And Methods: We performed a first-in-human, proof-of-concept, prospective single-arm multicenter clinical trial between March 2018 and February 2019 in patients who underwent endovascular aortic procedures at 4 high-volume centers.

Contemporary Surgical Management of Aberrant Right Subclavian Arteries (Arteria Lusoria).

Background: An aberrant right subclavian artery (ARSA) is in most cases an asymptomatic aortic arch anomaly. However, dysphagia, aneurysm formation (ARSAA), associated Kommerell diverticulum, or cerebellar/arm malperfusion may require invasive therapy. Large-scale clinical trials do not exist in current literature.

Endovascular Occlusion of a Renal Arteriovenous Fistula with Renal Vein Aneurysm Formation for Rupture Prevention.

Purpose: To report the effectiveness of left renal artery (LRA) occlusion using Amplatzer Vascular Plug (AVP) II as treatment for a high-flow renal arteriovenous fistula (RAVF) with multiple renal vein aneurysms (RVA) to prevent aneurysm rupture and cardiac decompensation.

Case Report: A 59-year-old female suffering from a post-traumatic RAVF presented with tachycardia and increased cardiac output (CO). Doppler ultrasonography and computed tomography (CT) scan revealed a high-flow RAVF with multiple RVAs and unilateral critically reduced kidney function.

The JOTEC iliac branch device for exclusion of hypogastric artery aneurysms: ABRAHAM study.

Objective: Hypogastric artery aneurysms (HAAs) are rare but life-threatening in cases of rupture. Open or endovascular techniques traditionally aimed at occluding the hypogastric artery (HA) have considerable risk of pelvic ischemia. Iliac branch devices (IBDs) are indicated for aortoiliac aneurysms; however, they have also been used lately for HAAs.

Spinal meningioma, aortic aneurysms and the missing link of observation: the anchoring heuristic approach.

Over the last three decades, the development of systematic and protocol-based algorithms, and advances in available diagnostic tests have become the indispensable parts of practising medicine. Naturally, despite the implementation of meticulous protocols involving diagnostic tests or even trials of empirical therapies, the cause of one's symptoms may still not be obvious. We herein report a case of chronic back pain, which took about 5 years to get accurately diagnosed.

Acute Limb Ischemia-Much More Than Just a Lack of Oxygen.

Acute ischemia of an extremity occurs in several stages, a lack of oxygen being the primary contributor of the event. Although underlying patho-mechanisms are similar, it is important to determine whether it is an acute or chronic event. Healthy tissue does not contain enlarged collaterals, which are formed in chronically malperfused tissue and can maintain a minimum supply despite occlusion.

Temporal artery biopsy in the diagnosis of giant cell arteritis: Bigger is not always better.

Objective: Accurate early giant cell arteritis (GCA) diagnosis can be established through temporal artery biopsy (TAB). We herein investigate the relationship between specimen length and positive TAB result in a tertiary-care hospital in Germany during a 8-year period. Secondarily, we studied the relationships of specific epidemiological and laboratory parameters with positive TABs.

Open vascular treatment of median arcuate ligament syndrome.

Background: Median arcuate ligament syndrome is a rare condition with abdominal symptoms. Accepted treatment options are open release of median arcuate ligament, laparoscopic release of edian arcuate ligament, robot-assisted release of median arcuate ligament and open vascular treatment. Here we aimed to evaluate the central priority of open vascular therapy in the treatment of median arcuate ligament syndrome.

Outcomes after Open Surgery for Inflammatory Abdominal Aortic Aneurysm: A 10-Year Single-Center Experience.

Background: Inflammatory abdominal aortic aneurysms (IAAAs) are rare clinical entities with an exaggerated inflammatory component. The aim of this study is to report outcomes of a single-center 10-year experience in open surgical management of IAAA and to compare the results with noninflammatory, atherosclerotic abdominal aortic aneurysms (non-IAAAs).

Methods: We retrospectively reviewed the medical records of 18 patients with IAAA selected out of patients with AAA who underwent open surgery in the Department of Vascular and Endovascular Surgery at the University Hospital Dusseldorf from January 2006 to December 2015.

Pilomatrix carcinoma: More malignant biological behavior than was considered in the past.

Pilomatrix carcinoma is a very rare malignancy, with ~130 cases reported in the literature. In the past, pilomatrix carcinoma was considered to be a low-grade malignant tumor. Currently, however, its significant recurrence and metastatic potential has been well documented.

Chronic Mesenteric Ischemia: Patient Outcomes Using Open Surgical Revascularization.

Background: Chronic mesenteric ischemia (CMI) is a rare disease. Open treatment (OT) remains a valuable treatment option. We analyzed patient outcomes after OT and investigated health-related quality of life (HRQoL).

Iatrogenic Femoral Pseudoaneurysm and Secondary Ipsilateral Deep Vein Thrombosis: An Indication for Early Surgical Exploration.

Pseudoaneurysm formation often complicates transfemoral interventional procedures. Nonsurgical treatment consists of femoral compression and thrombin injection under ultrasound guidance. We report a 74-year-old man who was diagnosed with a pseudoaneurysm, following coronary angiography.

Deep Vein Thrombosis and True Crural Aneurysm: Misdiagnosis or Causal Relation?

True crural artery aneurysm is a rare clinical entity. Crural artery aneurysms are most frequently seen in men in their sixth decade without major cardiopulmonary diseases and are often associated with injury, superinfection, or vasculitis. We report the case of a 44-year-old man with a history of idiopathic deep vein thrombosis (DVT) as the first manifestation of a true crural artery aneurysm.

Ruptured Mycotic Aortic Aneurysm after Bacille Calmette-Guerin Therapy.

To report a case of a ruptured mycotic abdominal aortic aneurysm (MAA) after intravesical Bacille Calmette-Guerin (BCG) therapy because of bladder carcinoma. A 57-year-old male patient was admitted to our hospital for follow-up computed tomography 14 months after transurethral resection of a papillary carcinoma of the bladder and intravesical BCG therapy. The CT scan revealed a ruptured MAA aneurysm and the patient underwent an endovascular repair with an aorto-bi-iliac stent graft.
