Objective: The objective of this study was to assess whether functional genetic polymorphisms of matrix metalloproteinases (MMPs) 1, 3, 9, and 12 are associated with arterial enlargements or aneurysms of the thoracic aorta or popliteal arteries in patients with abdominal aortic aneurysm (AAA).
Methods: The associations between MMP1 (-1607 G in/del, rs1799750), MMP3 (-1171 A in/del rs35068180), MMP9 (13-26 CA repeats around -90, rs2234681, rs917576, rs917577), and MMP12 (G/T missense variation, rs652438) polymorphisms and enlargements or aneurysms of the thoracic aorta and popliteal arteries were tested in 169 consecutive AAA patients.
Results: Thoracic aorta enlargement or aneurysm (TE/A; maximum diameter, >35 mm) was detected in 34 patients (20.
Background: We sought to evaluate the midterm results of parallel-graft-endovascular aneurysm repair (pg-EVAR) for complex aortic anatomy in high-risk candidates for open surgical repair of abdominal aortic aneurism (AAA).
Methods: Clinical and radiographic information on 35 patients treated by pg-EVAR between March 2010 and December 2015 was retrospectively reviewed and analyzed. All patients presented with symptomatic aneurysms and were treated within 3 days of clinical presentation.
We report our experience with the urgent treatment of two high-risk patients with infected femoral artery pseudoaneurysms (IFAPs) with the placement of a self-expandable covered stent (SECS). In both cases, there was no perioperative mortality and the aneurysm exclusion was successful without early or late stent thrombosis/stent fracture nor acute or chronic limb ischemia or limb loss. There was no recurrence of local or systemic infection during the follow-up period.

A 75-year-old man presented with pain and swelling of the left buttock 1 month after a bone marrow biopsy of the left iliac crest. The patient was treated by percutaneous ultrasound-guided thrombin injection (UGTI).

We report the case of a cardiac papillary fibroelastoma, arising from the interatrial septum, symptomatic from distal embolization to lower limb arteries. Such a clinical presentation is extremely infrequent for cardiac papillary fibroelastomas.

Genotyping of MMP-1 (-1,607 G+/G-), MMP-3 (- 1,171 6A/5A), and MMP-9 microsatellite (13-26 cytosine-adenosine repeats around -90) from peripheral blood was performed in 137 AAA patients with two AAA diameter measurements (at least 3 months to 1 year apart). When the same technique (either ultrasound or computed tomography) was used for the two measurements, yearly GR was estimated and compared with MMP genotype and clinical features by linear and binary logistic regression.

Methods: MMP-1 (-1607 G in/del), MMP-3 (-1171 A in/del), and MMP-9 microsatellite ((13-26) CA repeats around -90) PMs have been determined (i) in 204 patients with cerebrovascular disease to assess the association with features of vulnerability in carotid plaques and prevalence of stroke, (ii) in 208 patients with UA/NSTEMI to assess the association with in-hospital clinical outcome.
Results: Plaques from carriers of MMP-1 G insertion showed significantly smaller plaques and thicker fibrous cap.
Late spontaneous recanalization of internal carotid artery is a very rare event. We describe three cases which came to our observation in which the occlusion was demonstrated both by angiography and Doppler ultrasound. Two of them had surgical treatment and the histological exam of the plaque showed multiple recanalization foci.

Three main local actions of heparin on the skin can be defined: (1) the anticoagulant action, (2) the microcirculatory-modulatory action determining important control of the microcirculation in case of excessive vasoconstriction or vasodilatation, and (3) the "facilitatory action" on skin permeability, allowing other drugs to diffuse better and faster into the skin (producing a therapeutic effect).

Superficial thrombophlebitis is a minimally thrombotic process of superficial veins associated with inflammatory changes and/or infection. Treatments generally include analgesics, elastic compression, anti-inflammatory agents, exercise and ambulation, and, in some cases, local or systemic anticoagulants.

Materials And Methods: From January 2000 to June 2006, 134 patients (118 men, 16 women; mean age 75.1 years) underwent EVAR.
Intima-media thickening (IMT) of carotid arteries and constrictive remodeling (CR) of atherosclerotic plaques are vascular pathologic characteristics that precede the onset of vascular events. SMC migration and proliferation are linked both to IMT and CR and are matrix metalloproteinase 9 (MMP-9) dependent. A genetic polymorphism (PM) of MMP-9, a CA (13-27) microsatellite in the promoter region, which accounts for differential expression of MMP-9, could be linked to progression of IMT and CR.

Patients with varicose veins, edema, but without initial skin alterations or complications, were included. Measurements of skin laser Doppler (LDF) resting flux (RF) venoarteriolar response (VAR), ankle swelling (RAS), and edema were made within 12 hours before and within 3 hours after the flights.

Case Reports: Two elderly women with histories of chronically infected hip prostheses were found to have iatrogenic leaking pseudoaneurysms of the external iliac artery due to hip surgery trauma in the past. Both were treated successfully with a Jostent Peripheral Stent-Graft.
This case concerns a 61-year-old woman presenting with middle aortic syndrome treated by an aortoaortic thoracoabdominal polytetrafluoroethylene bypass and a right renal Dacron bypass. The case was atypical because of the patient's advanced age at the time of clinical presentation.

Cerebral revascularization is possible only in case of patent carotid bifurcation, three patients, all of them symptomatic (2 TIA's and 1 amaurosis fugax) with a complete common carotid artery occlusion have been treated with a subclavian-carotid artery by-pass (2 PTFE, 1 reversed saphenous vein).

Methods: Seventy-seven consecutive and not selected patients, undergoing a surgical treatment requiring aortic cross clamping, were assessed also with a transthoracic dobutamine stress echocardiography. With electrocardiographic and echocardiographic monitoring ventricular ischemia or wall motion abnormalities, 5 micrograms/kg per min of chlorhydrate dobutamine for 5 minutes were infused, followed by other 10 micrograms/kg per min increased up to 40 micrograms/kg per min.

In their opinion it's very important to select the patients in accordance with some characteristics of the tumor (site, grading, mobility, depth, size, stage, involvement of locoregional nodes, ploidia). Intrarectal ultrasonography is thought be the most important diagnostic tool, both in preoperative diagnosis and in postoperative follow-up; it has a high sensibility to define the parietal invasion of rectal cancer and to recognize metastatic nodes.
