Although there is not uniform definition of high-risk percutaneous coronary intervention (PCI), patients with severe three-vessel disease, left main disease, single remaining patent vessel and/or depressed left ventricular ejection fraction are considered a high-risk population. In this setting, periprocedural hemodynamic instability represents a serious issue. Percutaneous mechanical circulatory support (MCS) devices may improve both safety and efficacy of high-risk PCI. Indeed, MCS help to maintain coronary perfusion pressure and reduce myocardial workload, providing the operator sufficient time to reach the target of complete revascularization. The most used MCS are intra-aortic balloon pump and Impella. There are a plenty of data in literature about the efficacy and safety of the use of MCS in high-risk PCI performed through the femoral access. However, there is a paucity of data about the use of MCS in transradial high-risk PCI. Radial over femoral access has been showed to reduce bleeding complications and therefore may further improve the outcome of high-risk PCI. Herein we report a case of transradial high-risk PCI supported by the Impella 2.5 L and review the available data on this topic.

This study was designed to compare the efficacy and safety of seaprose S and serratio-peptidase in the treatment of venous inflammatory disease. Forty patients entered the study (11 males, 29 females), mean age 54.3 years (range 30-77), mean weight 74.8 kg (range 51-96), with superficial thrombophlebitis. The trial was conducted following a controlled, between patients, randomized experimental design. Seaprose S was administered as 30 mg tablets at a daily dosage of 90 mg (one tab t.i.d.), and serratio-peptidase as 5 mg tablets, at a dose of 30 mg per day (two tabs t.i.d.), both orally, for 14 days. Twenty patients received seaprose S and 20 serratio-peptidase. The findings indicate that seaprose S was more effective and better tolerated than serratio-peptidase. Although the group of patients assigned to seaprose S had considerably more severe initial symptoms, by the end of treatment spontaneous pain was reduced 68.7% from the baseline mean score (from 3.2 to 1.0), as compared with a 63.3% reduction in the serratio-peptidase group (from 3.0 to 1.1). Pain on pressure was reduced 61.1% with seaprose S (from 3.6 to 1.4), compared to 57.6% with the reference treatment (from 3.3 to 1.4). Edema was reduced respectively 75% (from 1.6 to 0.4) and 56.2% (from 1.6 to 0.7); erythema diminished 72.4% (from 2.9 to 0.8) and 58.3% (from 2.4 to 1.0); nighttime cramps were 61.1% less (from 1.8 to 0.7) compared with 52.9% (from 1.7 to 0.8); hemorrhagic suffusion was 53.3% less (from 1.5 to 0.7) compared with 41.7% (from 1.2 to 0.7); cutaneous dystrophy was reduced by 11.1% (from 1.8 to 1.6) and 7.7% (from 1.3 to 1.2). At the end of the treatment with seaprose S efficacy was assessed as good or excellent in 85% of the cases, compared with 65% for serratio-peptidase. Seaprose S caused no adverse reactions. During serratio-peptidase treatment one patient reported diarrhea, requiring temporary dosage reduction and specific treatment. It can thus be confirmed that seaprose S was effective and well tolerated in patients with inflammatory venous diseases.

Objective: To evaluate diagnostic investigations, operative management and long-term outcome of atherosclerotic aneurysms of the subclavian artery., Design: A retrospective clinical study through a follow-up period of 68 months (8 months to 11 years)., Setting: Department of Vascular Surgery, University Hospital., Patients: Between 1983 and 1995, 5 patients with atherosclerotic aneurysms of the extrathoracic subclavian artery were reviewed. All patients presented a pulsatile supraclavicular mass. Ultrasonography and angiography confirmed the diagnosis and were useful in planning the operation., Interventions: Four patients were submitted, through a supraclavicular incision, to resection of the aneurysm and replacement of a prosthetic graft (dacron in 2 cases, PTFE in the remaining 2 cases). In one patient, with a small saccular aneurysm, a tangential aneurysmectomy with a patch angioplasty (PTFE) was performed., Results: All patients recovered after a mean hospital-stay of 9 days and had a valid radial pulsation. During the follow-up period, a dacron graft failure occurred 38 months later in one patient: she remains today asymptomatic., Conclusions: Resection is today recommended for all patients with diagnosed subclavian artery aneurysms. Because of unknown natural history of asymptomatic aneurysms, with an unpredictable risk of complications, more accurate evaluations are required for optimal clinical decision making (early surgery vs watchful waiting?).
