PURPOSE: To report the use of the octopus endograft technique to treat a patient with a ruptured thoracoabdominal aortic aneurysm (TAAA). CASE REPORT: A 46-year-old man was diagnosed with a contained rupture of a 9-cm type V TAAA. The presence of an occluded superior mesenteric artery (SMA), a stenotic celiac trunk, an enlarged inferior mesenteric artery (IMA), and rich collaterals with the SMA and celiac trunk made endovascular repair with the octopus endograft technique appear feasible...

Bullet embolization to the right heart through the vasculature is seen infrequently in cases presenting with penetrating trauma. Patients with unstable hemodynamic status are managed operatively. For a patient with stable hemodynamic parameters, diagnostic evaluation such as computed tomography angiogram, echocardiogram, or angiography could be performed to select the best treatment option. Endovascular treatment is employed infrequently in these cases but can be a viable option for select patients. We present a case of a bullet embolus to the right ventricle treated successfully with endovascular approach and discuss the technical aspects of this approach...

Right coronary artery (RCA) originating from the left coronary system is a subtype of single coronary artery (SCA) anomaly, and the origin of RCA as a branch from the left anterior descending artery (LAD) is a very rare variant. A 55-year-old male who had a percutaneous coronary intervention (PCI) history was hospitalized due to acute coronary syndrome. Coronary angiography revealed an aberrant RCA originating from the mid-LAD as well as stent thrombosis. A successful PCI was performed and he was discharged from the hospital three days after the PCI...

Focused ultrasound (FUS) in combination with microbubbles temporally and locally increases the permeability of the blood-brain barrier (BBB) for facilitating drug delivery. However, the temporary effects of FUS on the brain microstructure and microcirculation need to be addressed. We used label-free optical coherence tomography (OCT) and OCT angiography (OCTA) to investigate the morphological and microcirculation changes in mouse brains due to FUS exposure at different power levels. Additionally, the recovery progress of the induced effects was studied...

Complex differential variance (CDV) provides phase-sensitive angiographic imaging for optical coherence tomography (OCT) with immunity to phase-instabilities of the imaging system and small-scale axial bulk motion. However, like all angiographic methods, measurement noise can result in erroneous indications of blood flow that confuse the interpretation of angiographic images. In this paper, a modified CDV algorithm that corrects for this noise-bias is presented. This is achieved by normalizing the CDV signal by analytically derived upper and lower limits...

Introduction: Dysphagia is a risk factor for aspiration pneumonia and acute respiratory failure in acute stroke patients. Dysphagia lusoria is caused by compression on the esophagus from artery lusoria, when the aberrant right subclavian artery arises from the descending aortic arch. We present a rare case report of pre-stroke undiagnosed dysphagia lusoria as a cause of aspiration pneumonia with acute respiratory failure in a 67-year-old female patient admitted with a minor left intracerebral hemorrhage in the left basal ganglia...

An uncommon complication of iodinated contrast administration is the development of bilateral sialadenitis. We report a unique case of hyperacute unilateral parotiditis during diagnostic cerebral angiography of the external carotid artery, which mimicked possible iatrogenic vascular event associated with cerebral endovascular procedures. Discussion includes the differential diagnosis, diagnostic studies, and treatments for this unusual condition.

Pulmonary sequestration is a congenital malformation characterized by dysplastic pulmonary tissue which receives blood supply by arterial systemic system, not in communication with tracheobronchial tree. Although it could be asymptomatic, it can also cause recurrent infections and hemoptysis, rarely massive and fatal. The conventional treatment consists in surgical resection of the pulmonary sequestration, but in the last few years endovascular embolization has been proposed as a valid therapeutic alternative...

Bleeding of an aberrant right subclavian artery following transthoracic en bloc esophagectomy and intrathoracic gastric reconstruction is a rare but severe complication in esophageal surgery. Preoperative diagnosis can be achieved by computed tomography or magnetic resonance angiography (MRA). Various treatment options are available; thus, the treatment can be challenging and should be adjusted to the severity of the symptoms. Bleeding of an aberrant right subclavian artery can result from perioperative vascular injury or various postoperative complications...

Hereditary hemorrhagic telangiectasia or Osler-Weber-Rendu syndrome is a rare autosomal dominant vascular disorder characterized by epistaxis, mucocutaneous telangiectasias, and arteriovenous malformations affecting various organs and systems. The liver is a commonly involved organ (74% of patients with hereditary hemorrhagic telangiectasia), although symptomatic liver disease is quite infrequent. In symptomatic cases, clinical manifestations relate most commonly to the predominant type of vascular shunting present (arteriovenous, arterioportal, or portovenous)...

Interrupted aortic arch is an extremely rare congenital malformation representing about 1% of congenital heart disease. Early symptoms usually occur early in the neonatal period and clinical deterioration is often rapid and long-term prognosis is limited. Nonetheless, this condition has been identified later in adult life in rare cases. We report a case in an adult male with absence of hypertension history and no further cardiac compromise, with a severe posterior chest pain alongside dyspnea and sweating. Computed tomography angiography revealed interrupted aortic arch type A, bivalve aorta, hemopericardium, aortic dissection Stanford A, and important collateral circulation...

A 40-year-old man was admitted to our hospital for chest pain after smoking. Coronary computed tomography angiography showed severe stenosis in the left anterior descending artery. The stenosis site had no plaque on stretched curved multiplanar reconstruction and short-axis images. Coronary angiography revealed improvement of the severe stenosis after the intracoronary administration of isosorbide dinitrate in the left anterior descending artery. Intravascular ultrasound demonstrated negative remodeling without a plaque and diffuse intima with media thickening at the stenosis site...

Background: Duchenne muscular dystrophy (DMD) is an X-linked recessive skeletal muscle myopathy which is caused by mutations in the dystrophin gene. Lack of dystrophin also results to cardiomyopathy, which raises significantly the stroke risk in DMD-patients. However, data about therapeutic opportunities in the acute setting are scarce in literature. So far, only two cases receiving IV thrombolysis are described, one of them with fatal outcome. Method: Case report of a case of successful mechanical thrombectomy (MTE) in an acute ischemic stroke (AIS) patient with DMD and associated dilatative cardiomyopathy...

It is well known that the apparent significant coronary stenosis on angiography sometimes does not cause significant ischemia, and vice versa. For this reason, decision-making based on coronary physiology is becoming more and more important. Fractional flow reserve (FFR), which has emerged as a useful tool to determine which lesions need revascularization in the catheterization laboratory, now has a class IA indication in the European Society of Cardiology guidelines. More recently, the instantaneous wave-free ratio, which is considered easier to use than FFR, has been graded as equivalent to FFR...

RATIONALE: Saphenous vein graft disease remains a major limitation of coronary artery bypass graft surgery (CABG). Up to 20% of vein grafts will occlude within the first year after CABG despite standard aspirin antiplatelet therapy. However, more potent postoperative platelet inhibition with ticagrelor may improve graft patency. The goal of this study will be to evaluate the efficacy of ticagrelor, as compared to aspirin, for the prevention of saphenous vein graft occlusion following CABG...

The purpose of this study was to validate the feasibility of contrast-enhanced transcranial Doppler sonography (CE-TCCD) in the diagnosis of Moyamoya disease (MMD). CE-TCCD data on patients with MMD were analyzed. The CE-TCCD data were classified qualitatively into four patterns by two independent investigators: normal vascular color Doppler signal (pattern 1), augmented color Doppler signal with identifiable vascular structure (pattern 2), confluent color Doppler signal filling more than two-thirds of the display frame without identifiable vascular structure (pattern 3) and confluent color Doppler signal filling full display (pattern 4)...

BACKGROUND: Noninvasive cardiovascular magnetic resonance (CMR) techniques including arterial spin labeling (ASL), blood oxygenation level-dependent (BOLD), and intravoxel incoherent motion (IVIM), are capable of measuring tissue perfusion-related parameters. We sought to evaluate and compare these three CMR techniques in characterizing skeletal muscle perfusion in lower extremities and to investigate their abilities to diagnose and assess the severity of peripheral arterial disease (PAD)...

Vascular complications in the femoral artery puncture site are the most common complications of the coronary angiography. Femoral hematoma is the leading participant of the vascular complications. We investigated the femoral hematoma predictive value of angle of sheath to trochanter major in patients undergoing elective coronary procedures. In this prospective analysis, we evaluated the femoral hematoma predictive value of angle of sheath to trochanter major on 246 patients undergoing elective coronary procedures...
