Posterior nutcracker syndrome occurs when a retroaortic left renal vein becomes compressed between the abdominal aorta and the lumbar spine. Although open surgical approaches remain the treatment of choice, endovascular stenting has been used successfully. We describe a case of a 28-year-old man who presented with microscopic hematuria, left-sided flank pain, and testicular swelling. Computed tomography findings were consistent with posterior nutcracker syndrome. He underwent a novel hybrid operation that included left renal vein transposition followed by endovascular stenting...

Novel endovascular techniques hope to offer patients aortic arch repair with reduced morbidity compared to conventional arch surgery; however, current endovascular strategies remain challenged by the proximal seal zone, higher stroke rates, long-term durability and select anatomy. Hybrid arch repair offers patients a less invasive alternative that can treat more distal aorta than conventional arch repair yet still be performed via standard sternotomy. Areas Covered: This review will discuss the current evidence and future development of hybrid aortic arch and frozen elephant trunk reconstruction...

A 65-year-old gentleman with claudication underwent contrast-enhanced computed tomography. The scan showed occlusion of the infrarenal abdominal aorta and a 6.0 × 3.7 cm saccular zone-3 arch aneurysm. The left ventricular ejection fraction was 35% and a coronary angiogram revealed triple-vessel disease. In view of the patient's high risk with EuroSCORE II 20.34%, coronary artery surgery was combined with hybrid type I arch aneurysm repair. An endovascular stent was delivered in an antegrade manner. Open heart surgery and a hybrid type I arch intervention can be performed simultaneously through a midline sternotomy approach...

OBJECTIVES: To evaluate the procedural success and outcome of inter-atrial stenting. BACKGROUND: Inter-atrial stenting has been shown to be an effective way to maintain inter-atrial blood flow, however it is considered a high risk procedure, usually performed urgently in patients with significant hemodynamic compromise. METHODS: Between September 2004 and August 2016, inter-atrial stenting was attempted in 29 children. Procedural, clinical, and follow-up data were collected retrospectively...

A 63-year-old man presented with an asymptomatic infrarenal abdominal aortic aneurysm. He had scoliosis and atrophic right leg change as sequelae of poliomyelitis. The patient was not a candidate for endovascular aneurysm repair because of anatomic unsuitability. An open surgical repair was performed by the retroperitoneal approach because of severe scoliosis and left lateral aneurysm deviation. To minimize contralateral exposure, the Viabahn stent graft (W. L. Gore & Associates, Flagstaff, Ariz) was inserted in the right external iliac artery and anastomosed with the right expanded polytetrafluoroethylene graft limb...

A multilevel aneurysmatic lesion of the aorta is a rare pathology. The authors describe herein a clinical case report regarding stage-wise treatment of a patient presenting with aneurysms of the thoracic and abdominal portions of the aorta and a haemodynamically significant lesion of coronary and carotid arteries. Strategy of surgical management was decided upon collegially. Successful endoprosthetic repair of the aneurysm of the thoracic portion of the aorta required closure of the left carotid artery with a graft, which, taking into consideration an existing occlusion of the right internal carotid artery, demanded preliminary carotid-subclavian bypass grafting...

BACKGROUND: The technical and clinical success of the thoracic aortic endovascular procedures rests mainly on the choice of the proximal sealing zone (PSZ). The latter can be the affected by multiple complications, all of them having a potential gravity and a direct link with the quality of the PSZ. The objective of this study was to analyze the risk factors of the occurrence of complications of the PSZ. METHODS: Between 2007 and 2015, all the patients treated by a thoracic stentgraft in zones 2, 3, or 4 were retrospectively reviewed, with analysis of the pre- and postoperative angio-CT...

Chimney EVAR (CHEVAR) and Fenestrated EVAR (FEVAR) are two options for management of very complex abdominal aortic aneurysm (AAA). While some anatomical factors may favor one strategy over the other, there are some cases where the anatomical challenges may require using a hybrid approach. We are reporting the case of an 84-year-old male with a 6.8×5.7cm infrarenal abdominal aortic aneurysm that arises immediately below the level of the renal arteries and extends down to just above the iliac bifurcation with occluded celiac and inferior mesenteric arteries and severe bilateral renal artery stenosis with caudally oriented right renal and cranially oriented left renal artery...

INTRODUCTION: Conventional techniques of surgical correction of arch and descending aortic diseases remains as high-risk procedures. Endovascular treatments of abdominal and descending thoracic aorta have lower surgical risk. Evolution of both techniques - open debranching of the arch and endovascular approach of the descending aorta - may extend a less invasive endovascular treatment for a more extensive disease with necessity of proximal landing zone in the arch. OBJECTIVE: To evaluate descending thoracic aortic remodeling by means of volumetric analysis after hybrid approach of aortic arch debranching and stenting the descending aorta...

A 4-year-old male with headaches, papilledema, intracranial hypertension, and bilateral transverse sinus (TS) stenosis underwent attempted percutaneous placement of a right TS stent. Stent deployment was not technically feasible due to the stiffness of the stent and tortuosity of the patient's jugular bulb. Therefore, the patient underwent hybrid endovascular stenting of the right TS using neuronavigation and direct access of the TS following a single burr hole craniectomy. Two Express 8 mm × 17 mm balloon-mounted stents were deployed into the right TS, which resulted in obliteration of the preexisting trans-stenosis pressure gradient and decreased intracranial parenchymal pressure as monitored through an intracranial pressure bolt...

BACKGROUND: In chronic type B aortic dissection, late distal stent graft-induced new entry (SINE) has a possible negative role in long-term aortic remodeling. This study aimed to investigate the impact of SINE occurrence on survival by evaluating true and false lumen remodeling in thoracic and abdominal segments at midterm surveillance. METHODS: This study enrolled 65 patients with chronic type B aortic dissection (DeBakey type IIIb), who had received hybrid thoracic endovascular aortic repair (TEVAR) and had completed surveillance for at least 3 years...

A 26-year-old man presented with gunshot wound to the epigastrium. At surgery, he was hemodynamically stable and had a tense hematoma with thrill in zone 2 (right side) and porta triad. After liver injury was controlled, he underwent percutaneous stenting of a renal artery-vena cava fistula and the hepatic artery injury was followed. Historically, penetrating injury to zone 2 has mandated operative exploration. However, with the advent of endovascular options, in stable patients, catheter-based options offer a reasonable alternative with less risk of blood loss and possible nephrectomy...

Medicine and engineering are in collaboration to assist in the tackling of daunting surgical techniques which are associated with high rates of morbidity and mortality, in exchange for minimally invasive approaches with lower procedural risk. Endovascular procedures in general have already reduced the risk of surgery by limiting the extent of open surgery and often replacing it with purely percutaneous or hybrid procedures. Here, we describe a patient who had complex staged surgery with open repair of a proximal portion of a type A aortic dissection followed by a staged endovascular reconstruction of the arch and descending aorta by means of a fenestrated stent-graft to secure the left subclavian artery and the posterior cerebral circulation...
