Genicular Artery Embolization: A New Tool for the Management of Refractory Osteoarthritis-Related Knee Pain.

Osteoarthritis (OA) of the knee is a prevalent cause of chronic pain and disability, particularly affecting women. While traditionally attributed to chronic wear and tear, recent evidence highlights multifactorial pathogenesis involving low-grade inflammation and neoangiogenesis. Current therapeutic options include physical therapy, pharmacotherapy, and total knee arthroplasty (TKA).

Indocyanine green-marked fluorescence-guided off-clamp versus intraoperative ultrasound-guided on-clamp robotic partial nephrectomy: Outcomes on surgical procedure.

Objectives: To compare surgical and functional outcomes between off-clamp robot-assisted partial nephrectomy with indocyanine-green tumour marking through preliminary superselective embolization and on-clamp robot-assisted partial nephrectomy with intraoperative ultrasound identification of the renal mass.

Material And Methods: One hundred and forty patients with a single renal mass underwent indocyanine-green fluorescence-guided off-clamp robot-assisted partial nephrectomy with preoperative superselective embolization (Group A, 70 patients) versus intraoperative ultrasound-guided on-clamp robot-assisted partial nephrectomy without embolization (Group B, 70 patients). We assessed operative time, intraoperative blood loss, complications, length of stay, renal function, need for ancillary procedures and blood transfusions.

Endovascular management of KILT syndrome and COVID-19-related extensive deep vein thrombosis in a pregnant patient: A case report.

We report on a 20-year-old pregnant woman who tested positive for SARS-CoV-2 and was diagnosed with KILT syndrome, a rare condition that increases the risk of thrombotic events. The patient showed signs of deep vein thrombosis that extended from the bilateral iliac vein to the inferior vena cava (IVC), which was treated with placement of an IVC filter and endovascular thromboaspiration/thrombolysis. The IVC was successfully recanalized; however, during follow-up, thrombotic restenosis occurred at the filter level, requiring filter removal.

Prostate Artery Embolization in the Treatment of Massive Intractable Bleeding from Prostatic Neoplasms: A Case Report and Systematic Review.

Lower urinary tract symptoms (LUTS) and hematuria are common symptoms in men with neoplasms, mainly affecting the elderly population. Prostatic arterial embolization (PAE) is a minimally invasive procedure that has shown promising results in managing LUTS and massive intractable prostatic hematuria in patients with benign prostatic hyperplasia (BPH) and prostate cancer (PCa). A few studies, however, have provided valuable insights into the durability and efficacy of PAE focusing on the long-term effectiveness, quality of life, and cancer-specific control of hemostasis and urinary symptoms.

Covered stent assisted coil embolization of large Buhler aneurysm in setting of chronic celiac trunk occlusion.

Background: The arc of Bühler (AOB) is a residual embryonal anastomosis between the celiac artery (CA) and the superior mesenteric artery (SMA). Although usually asymptomatic, it has clinical relevance when compensatory reverse flow between the SMA and the CA in response to celiac artery obstruction leads to aneurysm formation and bleeding. Endovascular coiling is the mainstay therapy because of the deep AOB retropancreatic location, which hinders open surgery.

Transoral percutaneous radiofrequency ablation with a steerable needle and cementoplasty under CBCT and infrared augmented reality navigation system guidance for the treatment of a C1 solitary plasmacytoma: A case report.

We report a case of a 40-year-old female with a solitary plasmacytoma of the right transverse apophysis of C1 who underwent combined transoral ablation using a curved steerable needle and cementoplasty under CBCT and infra-red augmented reality navigation system. An imaging work-up revealed an osteolytic lesion determining partial collapse of the right lateral mass of C1 and involving the vertebral foramen. After a biopsy, that revealed a solid tissue consistent with plasmacytoma, it was decided to proceed with radiation therapy.

Spontaneous Soft Tissue Hematomas in Patients with Coagulation Impairment: Safety and Efficacy of Transarterial Embolization.

The aim of this study is to report the authors' experience of percutaneous transarterial embolization (TAE) in patients with spontaneous soft tissue hematomas (SSTH) and active bleeding with anticoagulation impairment.

Background: Infections following transjugular intrahepatic portosystemic shunt (TIPS) placement have been poorly described. We aim to investigate the rate and the potential predictors of infections occurring after TIPS placement.

Methods: Single center, retrospective, observational study.

Testicular artery originating from the inferior mesenteric artery: an alert for interventionalists - A case report.

Testicular arteries usually arise from the abdominal aorta. During an elective embolization of superior rectal arteries for hemorrhoidal disease performed in a 52-year-old male patient, a previously unreported vascular variant was identified. On selective angiography, the inferior mesenteric artery split into left colic artery and left testicular artery, without any evidence of vascular supply to the hemorrhoidal cushions.

Multivessel endovascular therapy for undiagnosed vascular type Ehlers-Danlos syndrome. Successful percutaneous transcatheter coil embolization of hepatic artery pseudoaneurysm with stenting of right renal and iliac arteries in emergency setting.

Among Ehlers-Danlos syndromes, the vascular type is the most severe because of its vascular complications. Transcatheter embolization of medium-sized arteries has become the first-line therapy for life-threatening hemorrhage. Ongoing multiple lesions causing hemorrhagic or ischemic complications in the acute phase can challenge patient management.

The combined use of stent retriever and neuro-aspiration as successful bail-out reperfusion strategy in a patient with embolic myocardial infarction.

Embolic myocardial infarction account for ≈3% of all ST-segment myocardial infarction and represents a challenge often left no-reperfused because current thrombectomy technologies are inefficient to grab thrombus wedged into distal coronary arteries. We present the case of a 34-year-old man who presented with anterior STEMI and a proximal left anterior descending coronary artery ulcerated plaque with a great thrombus burden, which led to distal embolization. Failure of several attempts of manual and rheolytic thrombectomy, led us to use the "Solumbra technique", the combined use of stent retriever and Penumbra catheter was successful in restoring patency and flow.

Percutaneous Transanastomotic Stent Graft Deployment to Salvage Dysfunctional Native Forearm Radiocephalic Fistulae: Feasibility and Primary Patency at 12 Months.

Purpose: To evaluate feasibility and efficacy of transanastomotic self-expandable polytetrafluoroethylene stent graft placement for salvage of radiocephalic arteriovenous fistulae (RCAVFs).

Materials And Methods: From 2008 to 2016, 26 patients (21 male; age, 38-80 y) with dysfunctional RCAVFs for juxtaanastomotic lesions that were unresponsive to angioplasty underwent transanastomotic stent graft placement. Stenotic and thrombotic lesions were included.

Under-dilated TIPS Associate With Efficacy and Reduced Encephalopathy in a Prospective, Non-randomized Study of Patients With Cirrhosis.

Background & Aims: Portosystemic encephalopathy (PSE) is a major complication of trans-jugular intrahepatic porto-systemic shunt (TIPS) placement. Most devices are self-expandable polytetrafluoroethylene-covered stent grafts (PTFE-SGs) that are dilated to their nominal diameter (8 or 10 mm). We investigated whether PTFE-SGs dilated to a smaller caliber (under-dilated TIPS) reduce PSE yet maintain clinical and hemodynamic efficacy.

Disabling portosystemic encephalopathy in a non-cirrhotic patient: Successful endovascular treatment of a giant inferior mesenteric-caval shunt the left internal iliac vein.

Hepatic encephalopathy is suspected in non-cirrhotic cases of encephalopathy because the symptoms are accompanied by hyperammonaemia. Some cases have been misdiagnosed as psychiatric diseases and consequently patients hospitalized in psychiatric institutions or geriatric facilities. Therefore, the importance of accurate diagnosis of this disease should be strongly emphasized.
