Abstract

ObjectiveTo document the recovery of vascular services in Europe following the first COVID-19 pandemic peak.MethodsAn online structured vascular service survey with repeated data entry between 23 March and 9 August 2020 was carried out. Unit level data were collected using repeated questionnaires addressing modifications to vascular services during the first peak (March - May 2020, "period 1"), and then again between May and June ("period 2") and June and July 2020 ("period 3"). The duration of each period was similar. From 2 June, as reductions in cases began to be reported, centres were first asked if they were in a region still affected by rising cases, or if they had passed the peak of the first wave. These centres were asked additional questions about adaptations made to their standard pathways to permit elective surgery to resume.ResultsThe impact of the pandemic continued to be felt well after countries' first peak was thought to have passed in 2020. Aneurysm screening had not returned to normal in 21.7% of centres. Carotid surgery was still offered on a case by case basis in 33.8% of centres, and only 52.9% of centres had returned to their normal aneurysm threshold for surgery. Half of centres (49.4%) believed their management of lower limb ischaemia continued to be negatively affected by the pandemic. Reduced operating theatre capacity continued in 45.5% of centres. Twenty per cent of responding centres documented a backlog of at least 20 aortic repairs. At least one negative swab and 14 days of isolation were the most common strategies used for permitting safe elective surgery to recommence.ConclusionCentres reported a broad return of services approaching pre-pandemic "normal" by July 2020. Many introduced protocols to manage peri-operative COVID-19 risk. Backlogs in cases were reported for all major vascular surgeries.

8. The contribution of oncovascular surgery in a young patient with idiopathic retroperitoneal fibrosis

Author

Kotsis, Thomas Christoforou, Panagitsa Polydorou, Andreas

Abstract

Surgical resection remains the cornerstone for the treatment of oncological disease. When a critical arterial or venous structure is involved in a tumor mass, successful relief of symptoms and long-term oncological control are achieved through careful preoperative planning by an interdisciplinary team that necessarily includes a vascular surgeon. We describe the involvement of a vascular surgeon in the oncology of a 22-year-old woman, who is diagnosed with idiopathic retroperitoneal fibrosis.

Abstract

Paraganglia are clusters of cells originating from the neural crest with histological and cytochemical characteristics of neuroendocrine cells. Paragangliomas of the head and neck represent less than 0.5% of all head and neck tumors and they usually occur between the ages of 40 and 50. Paragangliomas in childhood and in adolescence are extremely rare; only 23 case reports have been reported in the recent literature. In childhood, the estimation of malignant potential is 3–10%; therefore, early diagnosis and treatment of carotid body paragangliomas are mandatory. However, due to the rarity of these lesions in young patients, they are often not included in the differential diagnosis of solid masses in the neck area, a fact that may lead to misdiagnosis or delay in treatment. We present, herein, two extremely rare cases of patients in adolescence who were diagnosed with a carotid body paraganglioma and were treated surgically in our unit. One of the patients was diagnosed and treated at the age of 15 years while the other had a long-standing tumor in the neck that was followed up by a general surgery outpatient service as a branchial cleft cyst at the age of 15 years and was eventually treated surgically 8 years later. Carotid body tumor was not considered in the initial differential diagnosis because of its rarity at this age range.

Abstract

Objective: This is a prospective study concerning patients with symptomatic or asymptomatic significant carotid stenosis. Preoperative and intraoperative measurements of the peripheral extension of the carotid atherosclerotic plaque have been compared with postoperative measurements to identify a preoperative method that safely allows the performance of eversion carotid endarterectomy (ECEA). Materials and Methods: The study included 37 patients with symptomatic internal carotid stenosis greater than 70% and 43 patients with asymptomatic stenosis greater than 80%. Four methods were used for establishing criteria: preoperative Doppler examination, intraoperative measurement of the carotid atheroma before artery division, measurement of the removed plaque, and histological measurement of the plaque. Results: Preoperative Doppler examination is a method of estimating the actual distal extension of the internal carotid artery (ICA) atheroma, with correction as dictated by the following formula: AL = 0.6704+0.7685. Doppler In all cases, preoperative ultrasound measurements and intraoperative estimation confirmed the correct decision to proceed with the eversion technique. Conclusion: The peripheral extension of the atherosclerotic plaque of the ICA can be assessed with accuracy by preoperative Doppler study, which can be used with safety as a predicting criterion of the existence of healthy peripheral carotid tissue that allows the performance of the eversion endarterectomy technique.

Abstract

Purpose: The aim of the present study was to investigate a potential difference on the arterial stiffness among aneurysm patients and non-aneurysm controls, as well as to explore potential changes between patients treated either with endovascular or open repair. Materials and Methods: A 110 patients with an infrarenal AAA were prospectively enrolled in this study. Fifty-six patients received an EVAR, whereas 54 patients received an open surgical repair. Moreover, 103 gender and age-matched subjects without AAA served as controls. The cardio-ankle vascular index (CAVI) was applied for measurement of the arterial stiffness. Results: CAVI values were statistically higher in the AAA patients when compared with control subjects. Although at 48 hours postoperatively the CAVI values were increased in both groups when compared to baseline values, the difference in CAVI had a tendency to be higher in the open group compared to the endovascular group. At 6 months of follow up the CAVI values returned to the baseline for the patients of the open repair group. However, in the endovascular group CAVI values remained higher when compared with the baseline values. Conclusion: Patients with AAAs demonstrated a higher value of CAVI compared to healthy controls. A significant increase of arterial stiffness in both groups during the immediate postoperative period was documented. The increase in arterial stiffness remained significant at 6 months in EVAR patients. Further studies are needed to elucidate the impact of a decreased aortic compliance after stentgraft implantation on the cardiac function of patients with AAA.

28. A Pearl-Like 30-Year-Old Moving Phlebolith in the Left Cephalic Vein

Author

Kotsis, Thomas Christoforou, Panagitsa

Abstract

Background: Phleboliths are a common finding, especially in the pelvic veins. There are generally multiple thrombi associated with vascular malformations, trauma, or iatrogenic or noniatrogenic intravenous foreign bodies. Methods: Herein, we report a unique case of a single moving phlebolith in the cephalic vein of a 65-year-old man, not associated with any vascular lesion, trauma, or foreign body. Results: Too many cases of phleboliths have been reported in the literature since 1948, referred to vascular disorders, injuries, or foreign bodies. Only this work we are presenting refers to a phlebolith not associated with other vascular, pathological, or traumatic lesion. Conclusion: Phleboliths not associated with other vascular lesions are not common and less rare when not associated with injuries or iatrogenic interventions. Clinicians should be aware of the existence of this pathology and include it as the differential diagnosis of various pathological conditions.

Abstract

PURPOSE: The purpose of this study was to evaluate the role of immunohistochemical markers in the prediction of malignancy in paragangliomas. METHODS: Our institute's patient records between 1990-2012 were retrieved in order to identify patients who were treated for paragangliomas. Size and location of the tumour, existence of concurrent metastatic disease, patient demographics and survival were recorded. Haematoxylin-eosin stained slides were reviewed and all tumours were stained specifically for neuron specific enolase (NSE), chromogranin, synaptophysin and S100 protein positivity. Positivity and expression patterns of the above markers were evaluated and compared between malignant and benign tumours. Malignant behaviour was defined when patient had concurrent or subsequent lymph node involvement, local recurrence and/or metastases. RESULTS: A total of 22 patients with a diagnosis of paraganglioma were treated in our institutes. Female to male ratio was 1.75: 1. The mean age was 43.5 and 51.6 years for women and men, respectively. In 5 patients the tumors had malignant clinical behavior. Their mean size was 3.65 cm for benign and 4.56 cm for malignant neoplasms. NSE expression was diffuse in 47.1% and 0% for benign and malignant tumors, respectively (p=0.10). S100 expression in the periphery of the tumour was typical in 88.2% and 0% for benign and malignant tumors, respectively (p

Abstract

The third-generation thienopyridine prasugrel has much stronger antiplatelet effect compared to other current antiplatelet inhibitors and exhibits practically zero resistance in healthy people. Prasugrel is used as a pre-and post-treatment in percutaneous coronary or neurovascular interventions with parallel aspirin regime. However, as there is a higher reported bleeding with intraluminal interventions and meticulous technique is recommended, there is nearly non-existent international experience of open surgery under full prasugrel treatment. We present, herein, a case of open carotid endarterectomy with the eversion technique in an asymptomatic patient with carotid stenosis, who was receiving dual antiplatelet therapy with aspirin and prasugrel, due to a previous insertion of two newer drug-eluting stents at the left anterior descending artery and the right coronary artery. The resistance test to prasugrel showed complete inhibition of platelet function. Open surgery was performed under continuation of prasugrel treatment and interruption of aspirin for 3 days before surgery. No perioperative and postoperative neurologic or cardiologic event occurred. No bleeding at the cervical or cerebral area was noted.

Abstract

Surgical resection remains the cornerstone for the treatment of oncological disease. When a critical arterial or venous structure is involved in a tumor mass, successful relief of symptoms and long-term oncological control are achieved through careful preoperative planning by an interdisciplinary team that necessarily includes a vascular surgeon. We describe the involvement of a vascular surgeon in the oncology of a 22-year-old woman, who is diagnosed with idiopathic retroperitoneal fibrosis. [ABSTRACT FROM AUTHOR]

Abstract

Background: Liver regeneration is a complex procedure in which insulin metabolism has been implicated. The aim of this experimental study was to evaluate the role of insulin in rat hepatic regeneration following major hepatectomy (70%), employing an isolated perfused rat liver (IPRL) model to assess the extraction of insulin from the regenerating liver. Methods: Eighty-six male rats were randomized in 9 groups. A group of rats was studied at postoperative day (POD) 1 having a sham operation while control rats had no operation. All other animals were subjected to 70% hepatectomy. In phase B, at POD 1, 2, 3, 5, 7, and 14, the IPRL was applied. The regenerating liver was perfused with insulin (450 mu/ml) at a flow of 1.4 ml/gr liver/min for 20 min. Animal weight, liver weight, glucose, lactate, aspartate transferase (AST), alanine transferase (ALT), total bilirubin, albumin, prothrombin time (PT), insulin clearance, and tissue proliferating cell nuclear antigen (PCNA) expression were recorded. Results: We observed reduction of the liver's biochemical activities resulting in increase of AST (684%), ALT (532%), PT (27.7%), international normalized ratio (72%), and total bilirubin (82.8%) at first POD, while a normalization of the essential liver's functions occurs at fifth POD. Endogenous insulin concentration increased, while insulin extraction by the liver was reduced at the first POD in animals who underwent hepatectomy (13.94 ± 0.8 vs 7.97 ± 1.80 u/ml, p = 0.0005 and 71 ± 9.9 vs 165.88 µU/gr liver/min, respectively, p = 0.0005). Conclusions: Insulin seems to take part in hepatic regeneration, as the pancreas increases insulin production and the liver absorbs less despite the reduced hepatic mass and function.
