[Lower Limb Amputations in Patients with Peripheral Arterial Disease and/or Diabetes in Iceland 2010-2019; revascularisation, comorbidities and risk factors].

Introduction: No recent studies exist on lower extremity amputations (LLAs) in Iceland. The aim of this study was to investigate LLA incidence in Iceland 2010-2019 and preceding procedures in amputations induced by peripheral arterial disease (PAD) and diabetes mellitus (DM).

Material And Methods: Retrospective study on clinical records of all patients (>18 years) who underwent LLA in Iceland's two main hospitals during 2010-2019.

Percutaneous thrombin injection of common carotid artery pseudoaneurysm without cerebral protection.

An 83-year-old man with sepsis sustained right common carotid artery injury during attempted central-line placement. A computed tomographic scan showed a large hematoma in the patient's neck and a carotid pseudoaneurysm. His clinical condition was such that transfer to the interventional suite was judged unsafe.

[The correlation between toe- and ankle pressure, clinical symptoms and angiography in patients with leg ischemia].

Objective: The severity of leg ischemia is usually evaluated by measuring ankle pressure. This is a simple measurement but can be misleading in patients with severe sclerosis in ankle arteries in which case toe pressure is believed to be more reliable. The purpose of this study was to compare toe pressure with ankle pressure, clinical symptoms and angiography and thus evaluate the usefulness of toe pressure in the assessment of leg ischemia.

Carotid artery endarterectomy solely based on duplex scan findings.

The purpose of this study was to review experience with carotid artery surgery based on findings obtained solely from duplex scanning with special regard to unexpected findings during surgery and the early outcome. From January 1993 through December 1999, 271 consecutive patients underwent 287 carotid endarterectomies (CEAs), 229 (80%) of which were performed solely based on duplex scan findings. During the study period 5,932 carotid artery duplex scans were performed in 4,466 patients.

The impact of different spectral Doppler criteria on the proportion of high-grade internal carotid artery stenosis in patients undergoing duplex scanning.

Aim: To investigate the impact of different spectral Doppler criteria on the proportion of high-grade ICA stenosis in patients undergoing carotid artery duplex scanning.

Material And Methods: Duplex scans of 4,548 internal carotid arteries (ICA) in 2,349 patients were retrospectively analyzed. The following different criteria were applied for each scan for definition of ICA stenosis > or = 70%: Criteria I=ICA peak systolic velocity (PSV) > 130 cm/sec and ICA end-diastolic (EDV) > 100 cm/sec, Criteria II=PSV ICA/common carotid artery (CCA) ratio > 4, Criteria III=ICA PSV > or = 230 cm/sec, Criteria IV=ICA PSV > 230 cm/sec and/or ICA EDV > or = 100 cm/sec and/or PSV ICA/CCA ratio > or = 3.

Surgical reconstruction without preoperative angiography in patients with aortoiliac occlusive disease.

The objective of this study was to evaluate the feasibility of performing surgical reconstructions in patients with aortoiliac occlusive disease with findings obtained solely from duplex scanning. Between January 1995 through December 1999, among 112 patients who underwent surgical intervention due to aortoiliac occlusive disease, 44 were operated on with findings obtained solely from preoperative duplex scanning. Deviations from preoperatively planned surgical interventions according to duplex scan findings and the outcome were analyzed.
