Central venous catheter insertion and cancer represent some of the important predisposing factors for deep venous thrombosis (DVT). DVT usually develops in the lower extremities, and venous thrombosis of the upper extremities is uncommon. Early diagnosis and treatment of deep venous thrombosis are of importance, because it is a precursor of complications such as pulmonary embolism and postthrombotic syndrome. A 47-year-old woman visited our department with painful swelling on the left side of her neck. Initial examination revealed swelling of the region extending from the left neck to the shoulder without any redness of the overlying skin...

BACKGROUND: Carotid stent fractures are rare and multiple etiologies have been proposed to explain their occurrence. We present a patient with a internal carotid artery (ICA) stent who developed in-stent restenosis. We performed balloon angioplasty to address in-stent restenosis but post-procedure he developed a carotid stent fracture. To our knowledge, balloon angioplasty has not been reported to cause stent fractures and we report the first case report. CASE DESCRIPTION: 72-year-old male underwent stenting for symptomatic left ICA stenosis with post-stenting residual stenosis of 55%...

Reperfusion, despite being required for myocardial salvage, is associated with additional injury. We hypothesize that infarct size (IS) will be reduced by a period of bloodless reperfusion with hemoglobin-based oxygen carriers (HBOC) before blood-flow restoration. In the pig model, we first characterized the impact of intracoronary perfusion with a fixed volume (600 ml) of a pre-oxygenated acellular HBOC, HBOC-201, on the healthy myocardium. HBOC-201 was administered through the lumen of the angioplasty balloon (i...

Excessive vascular smooth muscle cell (VSMC) proliferation and migration after vascular injury significantly contributes to the development of occlusive vascular disease. Therefore, inhibiting the proliferation and migration of VSMCs is a validated therapeutic modality for occlusive vascular disease such as atherosclerosis and restenosis. In the present study, we screened chemical compounds for their anti-proliferative effects on VSMCs using multiple approaches, such as MTT assays, wound healing assays, and trans-well migration assays...

BACKGROUND During antegrade dissection re-entry (ADR) of chronic total occlusions (CTO), the first-generation Stingray catheter requires the use of large-bore guides (sheathless 7.5 Fr or 8 Fr), which increases the risk for access site-related complications and compromises radial approaches. Smaller guiding sizes necessitate long guidewires (e.g., 300 cm) or guidewire extensions for catheter advancement or removal. However, friction between guides and the Stingray catheter can result in unstable guidewire position or unintentional removal...

We describe a case of septal branch perforation during percutaneous coronary intervention of a right coronary artery chronic total occlusion. The septal branch perforation was treated with administration of autologous fat into the septal branch with significant reduction of extravasation. This treatment was followed by prolonged balloon inflation at the exit point of the septal branch in the donor artery which definitively sealed the perforation.

Percutaneous transhepatic obliteration (PTO) and percutaneous transhepatic sclerotherapy (PTS) are widely performed as an emergency measure in cases of variceal hemorrhage and intractable hepatic encephalopathy. The PTO/PTS technique is capable of directly blocking the blood supply in cases in which balloon-occluded retrograde transvenous obliteration (B-RTO) is not effective, or in cases with complicated collateral flow. Although PTO/PTS is not currently the first choice due to the invasiveness of transhepatic puncture, this procedure can modify the blood flow in an antegrade manner...

Subclavian artery (SCA) perforation is a rare complication while performing SCA intervention. In our present report, a 73-year-old female, with stenosis of the left SCA and situs inversus, presented with exercise-induced left arm weakness. The SCA stenosis was treated with direct stenting with a balloon-expansible Express LD 10×25 mm stent. However, it caused iatrogenic SCA perforation and hemothorax. The perforation was sealed by endovascular repair with operator-modified Endurant II graft stent, which complicated with occlusion of left common carotid artery...

Side branch occlusion, which was one of the common complications in percutaneous coronary interventions, was closely associated with cardiac death and myocardial infarction. Clinical guidelines also support the importance of preservation of physiologic blood flow in SB during PCI to bifurcation lesions. In order to avoid side branch occlusion during stent implantation, we often performed the jailed wire technique, in which a conventional guide wire was inserted to the side branch before stent implantation to the main vessel...

Non-traumatic cardiac arrest is a major public health problem that carries an extremely high mortality rate. If we hope to increase the survivability of this condition, it is imperative that alternative methods of treatment are given due consideration. Balloon occlusion of the aorta can be used as a method of circulatory support in the critically ill patient. Intra-aortic balloon pumps have been used to temporize patients in cardiogenic shock for decades. More recently, resuscitative endovascular balloon occlusion of the aorta (REBOA) has been utilized in the patient in hemorrhagic shock or cardiac arrest secondary to trauma...

BACKGROUND: High-pressure inflation for coronary stent deployment is universally performed. However, the duration of inflation is variable and does not take into account differences in lesion compliance. We developed a standardized "pressure optimization protocol" (POP) using inflation pressure stability rather than an arbitrary inflation time or angiographic balloon appearance for stent deployment. Whether this approach improves long-term outcomes is unknown. METHODS AND RESULTS: 792 patients who underwent PCI using either rapid inflation/deflation (n = 376) or POP (n = 416) between January 2009 and March 2014 were included...

BACKGROUND: Endovascular recanalization of a completely occluded proximal internal carotid artery (ICA) with underlying stenosis may be challenging owing to a possible thrombotic component. This is especially true when the landing zone for a balloon-tipped guiding catheter (BGC) at the bulb portion is insufficient. Sequential application of the balloons of a BGC and an angioplasty catheter may prevent thromboembolism during revascularization. This study analyzed the safety and effectiveness of this relay-balloon technique...

Peripheral arterial disease (PAD), caused by atherosclerotic processes, is allied with an increased risk of ischemic events, limb loss, and death. Recently, the use of a solid-state laser at 355 nm within a hybrid catheter was suggested for that purpose. In this work, short nanosecond pulses of a solid-state laser at 355 nm delivered through a hybrid catheter, composed of optical fibers and a blunt mechanical blade, are used to conduct a pre-clinical study and two clinical cases. The pre-clinical study consisted of an atherosclerotic calcified cadaveric leg and a porcine in vivo trial within the iliac artery, respectively...

Occlusion of an internal iliac artery or its branches is sometimes required prior to abdominal endovascular aneurysm repair. The Amplatzer vascular plug (AVP) is a useful device for this purpose, but it requires a large lumen catheter or guiding sheath to place it in the intended artery. We propose an anchor balloon technique for advancing this guiding sheath/catheter through a tortuous or angulated iliac artery for AVP placement.
