Abstract Antegrade femoral artery access is commonly used for percutaneous transluminal revascularization of ipsilateral lower limbs in patients with critical limb ischemia. While hemostasis at the ...end of the procedure can be achieved by manual compression, this may lead to an increase in local vascular complications. Femoral artery closure devices, such as the Angioseal collagen plug and anchor device, have been approved and shown of benefit after retrograde femoral artery catheterization. To date, there are however no data on the use of such arteriotomy closure device after antegrade femoral access. We hereby report a case series of five patients in whom Angioseal was successfully used after antegrade femoral puncture and below-the-knee percutaneous transluminal angioplasty. In all cases the device enabled immediate and complete hemostasis without major complications, despite the intense antithrombotic regimen, including heparin, aspirin, and clopidogrel in all patients, as well as glycoprotein IIb/IIIa inhibitors (in two patients) and fibrinolytic therapy (in one).
Abstract Antegrade femoral artery access is often used for diagnostic and interventional purposes in patients with critical limb ischemia, given its potential advantages in terms of visualization and ...back-up. However, it may be associated with an increased risk of local vascular complications, especially in the presence of common femoral artery atherosclerosis. We hereby report a case of antegrade femoral access in a previously stented common artery, which enabled successful recanalization of a totally occluded superficial femoral artery. Despite the procedural success, retroperitoneal bleeding occurred after sheath removal, which was nonetheless effectively managed with prolonged balloon inflations by means of contralateral femoral artery access. This clinical vignette, the first to date to report on antegrade access in a stented femoral artery, supports its feasibility despite the presence of a real bleeding risk.

We report a case of Wunderlich's syndrome in an obese woman associated with massive retroperitoneal hemorrhage. Stable hemodynamic patient condition was obtained by selective arterial embolization. ...Since the first embolization of a renal angiomyolipoma in 1976 by Moorhead et al., highly selective renal arterial embolization of angiomyolipoma with rupture has become a procedure that offers greater efficacy, particularly in life-threatening cases.
Symptomatic severe aortic stenosis (AS) in patients with intermediate-to-high surgical risk is currently being treated with transcatheter aortic valve replacement (TAVR). We present a case of a TAVR ...in a severe calcific AS with porcelain aorta and 'gothic' aortic arch. Pre-operative thoraco-abdominal computed tomography angiography showed also severe calcification at the sinotubular junction with protruding huge calcified nodules extending in ascending aorta and multiple calcific stenosis of both iliac-femoral vessels, severely tortuous. The choice of the interventional access was not easy and the high risk of an acute intra-procedural brain event guided the procedural planning. To our knowledge, this is the first case of TAVR with complete cerebral protection with Triguard system device and 'snaring-assisted' valve advancement.
Purpose:
To evaluate axillary artery access for the interventional treatment of carotid or splanchnic arteries that have angulated takeoff or complex anatomy when larger catheters (up to 9 F) are ...needed.
Technique:
The axillary artery approach was used to treat the left internal carotid artery (ICA) in 3 patients (2 angulated takeoffs and 1 bovine arch) and a celiac axis aneurysm. An 8-F, 45-cm-long introducer sheath was inserted for the carotid procedures, whereas a 9-F, 90-cm sheath was chosen for the celiac aneurysm. Cerebral protection and stenting were successfully performed in all carotid patients; an 8times40-mm stent-graft was implanted to exclude the celiac artery aneurysm. An 8-F vascular closure device was used in the axillary arteries; hemostasis was immediate, and no hematoma or other complications were recorded in follow-up.
Conclusions:
This preliminary experience revisits the axillary approach as an alternative access route for interventional procedures. In association with a vascular closure device, this approach should be considered as a useful and safe option for those interventional procedures in which larger sheaths or catheters are required to cope with difficult arterial anatomies.
Objectives This study was designed to better understand the functional correlates and the prognostic relevance of exercise-induced painless ischemia relative to painful ischemia in patients with ...stable coronary artery disease and previous myocardial infarction (MI).
Background The usefulness of exercise testing (ET) for predicting cardiac events, years after MI, although suggested and widely applied, is questionable. In particular, previous studies have reached conflicting conclusions as to whether exercise-induced painless ischemia is related to a less severe myocardial ischemia or to a different prognosis than painful ischemia.
Methods and Results Seven hundred sixty-six consecutive stable patients (mean age 57 ± 8.6 years, 89% men) with previous MI (mean time from MI 2.8 ± 0.75 years) who underwent a Bruce treadmill test and whose data were prospectively entered into our institutional database were enrolled. Patients were followed up for an average of 7 ± 0.6 years. End points were (1) cardiac death, (2) cardiac death or nonfatal reinfarction (primary), (3) cardiac death, nonfatal reinfarction, or unstable angina (secondary), and (4) cardiac death, nonfatal reinfarction, unstable angina, or revascularization procedures (secondary, restricted). These patients were retrospectively classified into 4 groups according to exercise test results: (1) painless ischemia, 156 patients; (2) painful ischemia, 75 patients; (3) negative ET, 99 patients; and (4) nondiagnostic ET, the remaining 436 patients. Patients with painless ischemia had less functional impairment and less exercise ischemia than the symptomatic patients (longer exercise duration
P < .001, higher double product
P < .001, higher ischemic threshold
P < .001, and shorter time to ST normalization
P < .001). Patients with painful ischemia had significantly (
P < .0005) increased 6-year risk rates of secondary and restricted end points (49% and 64%, respectively) versus those with painless ischemia (28% and 35%), no inducible ischemia (25% and 27%), or nondiagnostic ET (32% and 37%). Adverse outcomes were mainly the result of higher incidence of unstable angina or revascularization procedures. At multivariate analysis, neither painless nor painful exercise-induced ischemia were independent predictors of end points.
Conclusions Stable patients with previous MI represent a very low-risk population. In this subset, painless exercise-induced ischemia signifies less severe ischemia than the symptomatic one and has a limited prognostic power. Thus painless exercise-induced ischemia in stable patients with previous MI does not identify patients at increased risk. (Am Heart J 1998;136:894-904.)
