Venous thoracic outlet syndrome.

Venous thoracic outlet syndrome (vTOS) is a spectrum of disease caused by external compression of the subclavian vein as it passes through the costoclavicular space. Paget-Schroetter's Syndrome (PSS) or effort thrombosis is a subtype of vTOS where compression and microtrauma to subclavian vein from repetitive arm movements results in venous thrombosis. PSS or effort thrombosis mostly affects young otherwise healthy active individuals, and this further highlights the importance of this condition.

Nutcracker syndrome: diagnosis and therapy.

Nutcracker syndrome (NCS) is an extrinsic compression of the left renal vein (LRV) by the superior mesenteric artery (SMA) anteriorly and aorta posteriorly resulting in renal vascular congestion manifesting as hematuria, proteinuria, orthostatic hypotension, pain, or even renal dysfunction. Long-standing venous compression can encourage collateral drainage pathways through gonadal and pelvic veins, which may explain reported symptom and syndrome overlap with pelvic congestion syndrome. Diagnosis can be challenging and variable, frequently involving a combination of ultrasound Doppler, cross-sectional, and invasive imaging.

Safety and Feasibility of Ultrasound-Guided Gastric Access for Percutaneous Transabdominal Gastrostomy Tube Placement.

Background: The aim of the study was to evaluate the safety and feasibility of ultrasound guidance gastric access for percutaneous retrograde transabdominal gastrostomy (G)-tube placement.

Methods: Twenty-eight patients undergoing 31 percutaneous retrograde transabdominal G-tube placements utilizing ultrasound-guided gastric accesses were retrospectively identified.

Results: All patients had successful placement of G tubes with ultrasound-guided gastric access.

Endovascular Therapy for Vasculogenic Erectile Dysfunction: A Systematic Review and Meta-Analysis of Arterial and Venous Therapies.

Purpose: To systematically review and perform a meta-analysis on the safety and efficacy of endovascular therapy in the treatment of the two most common etiologies of vasculogenic erectile dysfunction (ED): veno-occlusive dysfunction (VOD) and arterial insufficiency (AI).

Materials And Methods: PubMed, Web of Science, ScienceDirect, and Scopus databases were searched for published English literature regarding endovascular ED treatments. Case series (n ≥ 3) were included.

Transcatheter Embolization of Cystic Artery Pseudoaneurysms Secondary to Acute Cholecystitis.

Cystic artery pseudoaneurysm is a rare entity most closely associated with trauma to the biliary vasculature (usually iatrogenic) or inflammation from adjacent cholecystitis. Most cases are treated intraoperatively during cholecystectomy. We describe 3 cases of cystic artery pseudoaneurysms secondary to acute cholecystitis, 2 with active hemobilia, treated with transcatheter embolization at our institution.

No catheter angiography is needed in patients with an obscure acute gastrointestinal bleed and negative CTA.

Purpose: To evaluate the negative predictive power of computed tomography angiography (CTA) for the identification of obscure acute gastrointestinal (GI) bleeding (GI bleeding not visualized/treated by endoscopy) on subsequent mesenteric angiography (MA) with the intention to treat.

Materials And Methods: A retrospective chart review of patients was performed who underwent mesenteric angiography for the evaluation/treatment of acute GI bleeding between November 2012 and July 2016. Patients with negative CTA examinations that proceeded to MA were identified.

Endovascular Management of Recurrent Spontaneous Hemarthrosis After Arthroplasty.

Purpose: Recurrent spontaneous hemarthrosis is an infrequent but debilitating late complication of joint replacement, affecting up to 1.6% of patients with arthroplasty of the affected joint. Repeated episodes of bleeding result in an inflammatory cascade that further propagates bleeding events.

Endovascular Treatment of a Dorsalis Pedis Artery Pseudoaneurysm.

Pseudoaneurysm of the dorsalis pedis artery (DPA) is an extremely rare entity that most commonly occurs secondary to trauma or surgery. All reported cases describe surgical treatment. We illustrate a case of enlarging DPA pseudoaneurysm causing pain and disability in a 49-year-old woman who was treated with transcatheter embolization and pseudoaneurysm aspiration resulting in near-immediate resolution of symptoms.

The MILLER banding procedure as a treatment alternative for dialysis access steal syndrome: a single institutional experience.

Objective: To describe a single institutional experience with minimally invasive limited ligation endoluminal-assisted revision (MILLER) for treatment of dialysis access steal syndrome (DASS).

Materials And Methods: Twenty patients were retrospectively identified that underwent 30 MILLER band procedures for DASS at our institution from March 2010 to December 2014. Technical success was defined by successful creation of MILLER band with preservation of flow for hemodialysis.

Ethylene vinyl alcohol copolymer (onyx) embolization for acute hemorrhage: a systematic review of peripheral applications.

Purpose: To evaluate the endovascular use of ethylene vinyl alcohol (EVOH) copolymer (Onyx; ev3 Endovascular, Inc, Plymouth, Minnesota) for the treatment of acute peripheral nonneurologic hemorrhage.

Materials And Methods: MEDLINE and PubMed databases were searched for articles published in English from 1946 to August 2014 describing patients treated for hemorrhage with EVOH copolymer outside of its usual neurovascular applications. Additional cases were collected from the bibliographies of relevant articles.

Isolation and characterization of Erythrobacter sp. strains from the upper ocean.

Seven strains of marine aerobic anoxygenic phototrophs belonging to the genus Erythrobacter were isolated. The strains were characterized regarding their physiological and biochemical properties, 16S rDNA and pufM gene sequences, morphological features, substrate preference, as well as pigment and lipid composition. All strains had functional type-2 reaction centers containing bacteriochlorophyll, served by small, light-harvesting complex 1, and were photosynthetically competent.
