REVIEW
Ioannis Bountouris, Georgia Kritikou, Nikolaos Degermetzoglou, Konstantinos Ioannis Avgerinos
The number of patients in dialysis increases every year. In this review, we will evaluate the role of percutaneous transluminal angioplasty (PTA) according to patency of arteriovenous fistula and grafts. The main indication of PΤΑ is stenosis > 50% or obstruction of the vascular lumen of an arteriovenous fistula and graft. It is usually performed under local anesthesia. The infection rate is as low as the number of complications. Fistula can be used in dialysis in the same day without the need for a central venous catheter...

We reported a case of ruptured tracheoinnominate fistula in a 14-year-old boy with history of repeated sternotomy. Tracheostomy was performed at age 2 years. Slide tracheoplasty was done at age 13 years. He presented to outpatient clinic with episodic hemosputum. Massive blood emanated from stoma during bronchoscopy evaluation. Venous-arterial extracorporeal membrane oxygenation was installed for resuscitation. A contrast-enhanced computed tomography (CT) and angiography confirmed the diagnosis. Immediate control of bleeding was achieved by an endovascular stent graft deployed at innominate artery...

Resection of the inferior vena cava (IVC) is a rare surgical technique that is occasionally combined with nephrectomy in the setting of renal malignancy with intravascular tumor extension. While this may be fairly well tolerated in some patients due to extensive collateralization in the venous system, there is a clear potential for lower extremity venous insufficiency and deep vein thrombosis (DVT). This report describes a patient who underwent right nephrectomy and segmental IVC resection from the subhepatic space to the iliac confluence, which was complicated by profoundly symptomatic lower extremity DVT and gastrointestinal hemorrhage due to system-to-portal shunting...

INTRODUCTION: Creating and maintaining a functional vascular access(VA) is a critical factor in the survival of a dialysis patient. However, it will not function forever, implying a creative attitude from the vascular surgeon either to maintain its functionality or built a new one wherever possible, being it autologous or synthetic. METHODS: Describe the VA history of a 59years-old male with morbid obesity and end-stage chronic kidney disease. RESULTS: His VA construction started in2012 with failed attempts in both forearms until a functional brachiocephalic artery-venous fistula(AVF) in the right upper limb was achieved, but was deemed to ligation as severe venous hypertension secondary to central venous disease related to CVC use...

OBJECTIVE: A suitable ipsilateral great saphenous vein (GSV) autograft is widely considered the best material for arterial reconstruction of a popliteal artery aneurysm (PAA). There are, however, cases in which such a GSV is absent, diseased, or of too small diameter for this use. Alternatives to GSV are synthetic conduits, but with a reduced long-term patency, in particular for infragenicular bypass; other venous autografts of marginal use; and stent grafts still in the first stages of their evaluation...

Stents are ubiquitously utilized in coronary and peripheral arterial disease. Interventional nephrologists, however, place stents in the venous outflow of the arteriovenous access. Stenosis is the predominant pathology that causes access dysfunction and will ultimately lead to thrombosis if uncorrected. Angioplasty and stent deployment are the current techniques available to combat stenosis. From initial bare metal stainless steel stents, the current generations of stents used are predominately covered nitinol stents...

Drug eluting stents (DES) have been increasingly being used for treatment of coronary artery disease (CAD) and have been shown to be very effective in prevention of primary in-stent restenosis (ISR). However DES have been increasingly associated with acute to subacute risk of stent fractures (SF). There is also a paucity of data about different management strategies for SF, especially in the long term. We present a case of recurrent ISR in an area of previous acute SF at the touchdown of saphenous venous graft (SVG) to first diagonal artery (D1)...

RATIONALE: Thrombosis due to anastomotic site stenosis is the most common complication in patients with brachio-axillary arteriovenous graft (AVG). Intravascular stent placement may play a special role in the salvage of dialysis grafts that have been previously performed percutaneous angioplasty or surgical procedure on the graft. Herein, we applied a novel stent named Supera which has a high degree of flexibility and resistance to external compression for treating a patient with recurrent venous anastomotic stenosis of brachio-axillary AVG...

BACKGROUND: Liver resection for intrahepatic cholangiocarcinoma (ICC) with invasion of the inferior vena cava (IVC) and hepatic veins (HV) is a challenging procedure. CASE PRESENTATION: We report a case of a 63-year-old woman with a 6-cm, centrally located liver mass. Her biochemistry results were normal except for a Ca19-9 level of 1199 U/ml. The liver biopsy was consistent with ICC and 60% macrosteatosis. Abdominal CT scans revealed a large central mass invading the left HV, middle HV and right HV, infringing on their junction with the vena cava...

BACKGROUND: There is no unanimous strategy for treating stenosis of the venous anastomosis (VA) of an occluded arteriovenous graft (AVG) following surgical thrombectomy. In this study, we compared classical surgical treatment and endovascular treatment procedures with the use of stent- graft in a single center study. The aim was to evaluate whether, the VA stenosis of thrombosed AVG treated endovascularly by stent-graft implantation, have as good results as surgical VA treatment, so that it may be considered the method of choice...

OBJECTIVES: Long-term patency of saphenous vein grafts (SVGs) remains a concern after coronary artery bypass grafting. Interventions to overcome this problem include monitoring intraoperative flow profile and, more recently, external stenting of SVGs. It is not known to what extent external stenting changes the perioperative flow characteristics of SVGs. The aim of this study was to assess whether the presence of an external stent affects perioperative graft flow parameters as evaluated by transit time flowmetry...

Iliac venous aneurysms are rare vascular abnormalities that may be manifested by abdominal masses, pelvic tenderness, or hypovolemia and may lead to rupture, thrombosis, pulmonary embolism, paradoxical embolism, or death. Inferior vena cava agenesis, like venous aneurysm, is an uncommon condition that may present with deep venous thrombosis. This report describes a patient with inferior vena cava agenesis and iliac venous aneurysm rupture treated with emergent iliocaval reconstruction and endovascular stent graft placement...

Despite the apparent superiority of arterial conduits for coronary artery bypass grafting (CABG), the long saphenous vein remains the most commonly used graft. The high failure rate of long saphenous vein grafts (SVGs) over time is therefore an important limiting factor for the long-term outcomes of CABG. Various methods to improve SVG patency have been proposed, although few have had a significant impact on clinical practice. External SVG supports have been a focus of research over the past 50 years, with their use intended to minimize well-documented pathophysiological changes that occur in the SVG following implantation into the coronary circulation...

INTRODUCTION: Suprahepatic caval resection and replacement of inferior vena cava (IVC) is standard procedure in deceased donor liver transplantation for patients with Budd-Chiari syndrome (BCS). However, replacement of IVC in living donor liver transplantation (LDLT) is difficult. We report a case of BCS successfully treated by LDLT without replacement of IVC. PRESENTATION OF CASE: A 52-years-old female with a primary BCS due to IVC thrombosis. A vena cava (VC) stent placed after angioplasty without improvement of the hepatic, portal venous flow and liver functions, Transjugular intrahepatic portosystemic shunt was considered and the patient had a rapid deterioration and increased ascites...
