Arterial ligation has been described in the literature as a safe and effective procedure with a relatively low number of patients requiring major amputations.
Horseshoe kidney is a congenital abnormality, with an incidence of 0.25% of the total population. Only 0.12% of patients who undergo an abdominal aortic aneurysm repair might also have a coexisting horseshoe kidney. We present a series of ten cases auspiciously treated with an endovascular approach along with their respective patient evolutions. A review of the literature is also presented.
The results of different chimney techniques in different zones of aortic arch were analyzed, so as to provide clues to decrease the complications of chimney thoracic endovascular repair (cTEVAR).
A maneuver is explained to show arterial flow and its runoff in patients with acute limb ischemia in whom neither the angiography nor the baseline Doppler can obtain a diagnosis of permeability. During the maneuver, the Doppler color scale should be set to the lowest speed. Plantar compression may result in an inverted flow in the artery since the arteriovenous precapillary communications are open. During the plantar decompress, the negative venous pressure created allows a transient arterial flow by aspira...
A man in very poor general condition, was admitted for acute thrombosis of the infrarenal aorta associated to a penetrating ulcer (PAU) of the distal thoracic aorta.
In critical limb ischemia patients, an association is assumed between depression and worse outcome for morbidity, such as major limb amputation. After major amputation, anxiety and depression are common. We aimed to determine the association of depressive and anxiety symptoms in the elderly with critical limb ischemia, especially after major limb amputation.
We report long-term survival in open surgical and endovascular patients treated for descending thoracic aortic aneurysms at a single tertiary center from 1984 - 2014 to study the impact of transition to TEVAR for thoracic aortic aneurysm repair.
Vascular Blowout Syndrome (VBOS) is a life-threatening condition secondary to direct tumor encasement or invasion in advanced stage malignancies. Endovascular management can be an alternative to surgical treatment in this fragile patient population providing a minimally invasive measure both acutely and prophylactically.
The protective effect of diabetes on the prevalence and growth rate in AAA has been shown in several recent studies. Whether the benefits of diabetes exist in patients following AAA repair is unknown. The aim of this review was to analyze the effects of diabetes on long-term mortality following AAA repair.
We prospectively evaluated the modified sandwich technique for treatment of complex aorto-iliac arterial lesions using commercial stent grafts selected according to the arterial cross-sectional area. The primary outcomes were technical feasibility and mid-term follow-up results.
This report describes our centres experience of a new approach using coil embolisation for femoral pseudo-aneurysms (PSA) in intravenous drug users (IVDU). Current treatment options for this challenging patient group currently include femoral/external iliac artery ligation and excision of the PSA, with or without revascularization. Radiological thrombin injection, endoluminal stent grafting and coil embolisation have not been widely studied in this patient group and are most commonly reserved for sterile ps...
Phleboliths are a common finding, especially in the pelvic veins. There are generally multiple thrombi associated with vascular malformations, trauma or iatrogenic or non-iatrogenic intravenous foreign bodies.
It has long been reported that cryogenic allografts have sub-optimal mid and long-term patencies and consequently, are only used in the absence of autologous vein, predominantly in lower extremity limb salvage situations. As such, we felt that our recent experience with an upper extremity bypass for limb salvage using a cryogenic saphenous vein allograft, which aneurysmally degenerated after one-month and required multiple endovascular rescues, serves to re-emphasize such concerns as well as the importance ...
Radiation therapy may accelerate atherosclerosis with progressive stenosis and occlusions of the supra-aortic trunks.
Critical Limb Ischemia (CLI) patients who do not undergo revascularization are at great risk for major lower extremity amputation. It has been reported that less than half (49%) of a reference Medicare amputation population had any diagnostic vascular evaluation prior to a major lower extremity (LE) amputation. We were surprised by these data so we reviewed the preoperative evaluation in all patients who had a major LE amputation. We propose that significantly more patients will have a vascular evaluation p...
Increased arterial stiffness has been related to altered cardiovascular hemodynamics, left ventricular hypertrophy and a higher risk for cardiac events. Pulse wave velocity has been used as a surrogate marker for arterial stiffness. Treatment of abdominal aortic aneurysms (AAAs) involves insertion of a rigid graft or endograft inside the arterial system which has been shown to increase arterial stiffness, but the cardiac implications of these alterations are mostly unknown. We report a case of a patient wit...
The aim of our study was to assess the prevalence of concomitant arterial abnormalities (true aneurysms of iliac, common femoral, renal, visceral arteries and stenoses of iliac and renal arteries) in patients with abdominal aortic aneurysm, and to evaluate whether the type of the aneurysm (suprarenal versus solely infrarenal) is associated with this prevalence.
Aortic graft infections are a feared complication of aortic bypass operations and impart significant morbidity and mortality when they occur. The most common etiology is bacterial, with a presentation ranging from subclinical to acute depending on the organism. Fungal infections of prosthetic grafts are rare, especially in immunocompetent patients. Graft infections remain a clinical diagnosis. We report a rare case of an aortobifemoral graft infection with Histoplasma capsulatum that was diagnosed on surgic...
We present the case of an 89-year-old man with 3-month history of hoarseness and no other significant clinical manifestations. Flexible laryngoscopy revealed a paralyzed left vocal cord, and contrast-enhanced computed tomography showed a thoracic dissecting aortic aneurysm of the distal aortic arch and proximal descending aorta. The aortic aneurysm was repaired through implantation of an endovascular stent graft and the patient was discharged uneventfully after a week. The false lumen was completely thrombo...
A 21-year-old man was referred to our department for treatment of multiple aneurysms, including bilateral renal artery aneurysms. He was clinically diagnosed with Loeys-Dietz syndrome. So, we developed a two-stage surgical strategy. The first surgery involved reconstructing the right renal artery and replacing part of the abdominal aorta, bilateral common iliac artery, and bilateral internal and external iliac arteries with a synthetic graft. Although stent grafting of the left renal artery aneurysm had bee...
A 67-year-old man was admitted to the emergency unit with abdominal pain. An infrarenal aortic aneurysm with a diameter of 70 millimeters was detected by computed tomography (CT). In the catheter laboratory, graft stents were implanted into the infrarenal aorta total occlusion of the right renal artery was seen in angiography. The graft stent was punctured with a 30° angled Brockenbrough catheter and another stent was implanted.
Hepatic Hydatid cyst (HHC) are common in endemic areas. Mostly they are asymptomatic but some cause serious complications. We report two cases of HHC complicated arterial bleeding. Due to signs of active bleeding, the patients were treated with selective embolization of the hepatic artery to stop the bleeding and stabilize the patients' condition. Subsequently, partial hepatectomy of the involved liver lobe was performed in an elective setting and without post-operative complications. We recommend bridging ...
Pseudoaneurysm after pancreas transplantation has a reported incidence of 1.4% to 8.0% and may be caused by perioperative infection. Subsequent pseudoaneurysm rupture is a rare cause of arterioenteric fistula. Only 28 cases of arterioenteric fistula after pancreas transplantation have been reported in the past 20 years. We experienced a rare case of arterioenteric fistula resulting from pseudoaneurysm rupture after pancreas transplantation. We successfully treated the arterioenteric fistula with multi-stage...
Hypothenar Hammer Syndrome (HHS) is an uncommon vascular syndrome of upper extremity. HHS should be considered in patients who are presented with digital ischemia. Distal ulnar artery compression at the level of Guyon's canal with trauma result in thrombus or aneurysm. It may be observed following repetitive chronic trauma or acute blunt trauma to hypothenar eminence. Middle-aged male laborers, smokers and dominant hands are affected frequently. Hand pain, discoloration or ulceration of digits, cold intoler...
We report a case of saphenous vein bypass aneurysm and arteriovenous fistula in a 65-year-old man, 20 years after an in-situ vein bypass for occlusive disease. He was found to have patent venous branches which kept the bypass open despite distal anastomotic occlusion. The saphenous vein was successfully excised without distal revascularization, due to sufficient native arterial flow. This is the first reported case of aneurysmal degeneration of an in-situ vein conduit with occluded distal anastomosis and pa...
