RR5. Surgical Treatment of Popliteal Aneurysms Using a Posterior Approach: Thirteen Years' Follow-up
OBJECTIVES : Long-term results of posterior approach (PA) for the treatment of popliteal artery aneurysms are lacking in the literature. We compared our results with this access with those from a standard medial approach over a 13-years\u2019 period.
METHODS: Clinical data of all patients treated for a popliteal aneurysm between 2/1998 and 10/2011 were retrospectively reviewed and outcomes analyzed: Kaplan-Meier method with log-rank, chi2 and Wilcoxon test were employed for analysis.
RESULTS : A total of 78 aneurysms were treated in 66 patients (65 men). Mean age was 68 years (range 48-96 years).
Thirty-six aneurysms were asymptomatic (46%). Mean sac diameter was 2.9\ub11 cm. A PA was used in 43 cases (55%) and a medial approach (MA) in 35. All PA consisted in aneurysmectomy with an interposition graft with end to end anastomoses; among MA 25 interposition grafts and 10 bypass were performed. A PTFE graft was used mostly (57 cases). The two groups differed for age only (median 65.4 for PA vs. 72.9 for MA p=0.01). Five patients had an early thrombosis and required a Fogarty thrombectomy (2 PA and 3 MA, all PTFE grafts). Mortality rate at 30 days was 0%.
One patient suffered a peroneal nerve lesion (permanent) and another one a major wound necrosis with tissue loss (both PA). There were no early amputations. Median follow-up was 58.8 months (range 5 days-166.7 months).
Nine patients died during follow-up for unrelated causes. The 5-year primary and secondary patency rates were 58.9%\ub18,7% and 96.4%\ub13.5% respectively for PA, and 67.4%\ub110,4% and 81.3%\ub18,9% respectively for MA (p=0.41 for primary patency rate and 0.28 for secondary patency rate). Limb salvage was 100% and 93.3%\ub16.4% at 5 and 10 years respectively for PA and 91.5%\ub15.6% at both time points for MA (p=0.3).
CONCLUSIONS : PA in our experience was burdened by a few more early complications compared to MA. However in the long term it provided results which compare favorably to MA.

How the First Year of the COVID-19 Pandemic Impacted Patients’ Hospital Admission and Care in the Vascular Surgery Divisions of the Southern Regions of the Italian Peninsula
Background: To investigate the effects of the COVID-19 lockdowns on the vasculopathic population. Methods: The Divisions of Vascular Surgery of the southern Italian peninsula joined this multicenter retrospective study. Each received a 13-point questionnaire investigating the hospitalization rate of vascular patients in the first 11 months of the COVID-19 pandemic and in the preceding 11 months. Results: 27 out of 29 Centers were enrolled. April-December 2020 (7092 patients) vs. 2019 (9161 patients): post-EVAR surveillance, hospitalization for Rutherford category 3 peripheral arterial disease, and asymptomatic carotid stenosis revascularization significantly decreased (1484 (16.2%) vs. 1014 (14.3%), p = 0.0009; 1401 (15.29%) vs. 959 (13.52%), p = 0.0006; and 1558 (17.01%) vs. 934 (13.17%), p < 0.0001, respectively), while admissions for revascularization or major amputations for chronic limb-threatening ischemia and urgent revascularization for symptomatic carotid stenosis significantly increased (1204 (16.98%) vs. 1245 (13.59%), p < 0.0001; 355 (5.01%) vs. 358 (3.91%), p = 0.0007; and 153 (2.16%) vs. 140 (1.53%), p = 0.0009, respectively). Conclusions: The suspension of elective procedures during the COVID-19 pandemic caused a significant reduction in post-EVAR surveillance, and in the hospitalization of asymptomatic carotid stenosis revascularization and Rutherford 3 peripheral arterial disease. Consequentially, we observed a significant increase in admissions for urgent revascularization for symptomatic carotid stenosis, as well as for revascularization or major amputations for chronic limb-threatening ischemia

Relevance of inflammation and matrix remodeling in abdominal aortic aneurysm (AAA) and popliteal artery aneurysm (PAA) progression.
Aneurysm is a multifactorial degenerative disease characterized by focal dilatation of blood vessels. Although abdominal aortic (AAA) and popliteal aneurysms (PAA) are the most common dilatative vascular diseases and share some features, a comparison between the different anatomical sites and the relative pathophysiological differences has not been established. In order to gain deeper insights to AAA and PAA, we have characterized the role of matrix remodelling, vascular cells phenotype depletion and the inflammatory process in both diseases. Results show a more extensive presence of T-cell, B-cell and monocyte-macrophage infiltration in AAA with respect to PAA. Concurring with this aspect, IL-6, IL-8 and MCP-1 are 10-fold increased in AAA. Moreover, MMP-9, and metalloproteinase inhibitor 3 (TIMP3) resulted up-regulated in AAA tissues. Regarding the catalytic activity, which is tightly related to the oxidative stress, we found an up-regulation of superoxide dismutase [Mn] mitochondrial (SODM), glutathione peroxidase 3 (GPX3) and peroxiredoxin-1 (PRDX1). Histological analyses clearly showed a massive elastin fragmentation in AAA. This may enhance the inflammatory response, which has a prevalent role in AAA, while PAA is mainly guided by a loss of the contractile phenotype. These findings suggest insight in these potentially devastating diseases in term of their progression, aiming to identify potential specific markers respectively for AAA and PAA treatment
Focus on the Most Common Paucisymptomatic Vasculopathic Population, from Diagnosis to Secondary Prevention of Complications
Middle-aged adults can start to be affected by some arterial diseases (ADs), such as abdominal aortic or popliteal artery aneurysms, lower extremity arterial disease, internal carotid, or renal artery or subclavian artery stenosis. These vasculopathies are often asymptomatic or paucisymptomatic before manifesting themselves with dramatic complications. Therefore, early detection of ADs is fundamental to reduce the risk of major adverse cardiovascular and limb events. Furthermore, ADs carry a high correlation with silent coronary artery disease (CAD). This study focuses on the most common ADs, in the attempt to summarize some key points which should selectively drive screening. Since the human and economic possibilities to instrumentally screen wide populations is not evident, deep knowledge of semeiotics and careful anamnesis must play a central role in our daily activity as physicians. The presence of some risk factors for atherosclerosis, or an already known history of CAD, can raise the clinical suspicion of ADs after a careful clinical history and a deep physical examination. The clinical suspicion must then be confirmed by a first-level ultrasound investigation and, if so, adequate treatments can be adopted to prevent dreadful complications
