Insight from an Italian Delphi Consensus on EVAR feasibility outside the instruction for use: the SAFE EVAR Study
BACKGROUND: The SAfety and FEasibility of standard EVAR outside the instruction for use (SAFE-EVAR) Study was designed to define the attitude of Italian vascular surgeons towards the use of standard endovascular repair (EVAR) for infrarenal abdominal aortic aneurysm (AAA) outside the instruction for use (IFU) through a Delphi consensus endorsed by the Italian Society of Vascular and Endovascular Surgery (Societa Italiana di Chirurgia Vascolare ed Endovascolare - SICVE). METHODS: A questionnaire consisting of 26 statements was developed, validated by an 18 -member Advisory Board, and then sent to 600 Italian vascular surgeons. The Delphi process was structured in three subsequent rounds which took place between April and June 2023. In the first two rounds, respondents could indicate one of the following five degrees of agreement: 1) strongly agree; 2) partially agree; 3) neither agree nor disagree; 4) partially disagree; 5) strongly disagree; while in the third round only three different choices were proposed: 1) agree; 2) neither agree nor disagree; 3) disagree. We considered the consensus reached when >70% of respondents agreed on one of the options. After the conclusion of each round, a report describing the percentage distribution of the answers was sent to all the participants. RESULTS: Two -hundred -forty-four (40.6%) Italian Vascular Surgeons agreed to participate the first round of the Delphi Consensus; the second and the third rounds of the Delphi collected 230 responders (94.3% of the first -round responders). Four statements (15.4%) reached a consensus in the first rounds. Among the 22 remaining statements, one more consensus (3.8%) was achieved in the second round. Finally, seven more statements (26.9%) reached a consensus in the simplified last round. Globally, a consensus was reached for almost half of the proposed statements (46.1%). CONCLUSIONS: The relatively low consensus rate obtained in this Delphi seems to confirm the discrepancy between Guideline recommendations and daily clinical practice. The data collected could represent the source for a possible guidelines' revision and the proposal of specific Good Practice Points in all those aspects with only little evidence available
Cavoatrial junction stenting in vascular hemodialysis catheter malfunction
: In patients undergoing hemodialytic treatment via intravascular catheters, stenosis or occlusion of central veins is common. Despite an extensive characterization of Superior Vena Cava Syndrome (SVCS) no data is available about CavoAtrial Junction (CAJ) stenosis. We report the case of two patients with a story of multiple catheter failures due to thrombosis or infection. Computed tomography (CT) showed radiological signs of CAJ stenosis confirmed at the following venography. In absence of other feasible options to place a vascular access, the two underwent stenting with Gore Viabahn VBX balloon expandable endoprosthesis (W.L. Gore & Associates, Flagstaff, AZ, USA) of the CAJ stenosis. Completion venography showed complete resolution of the stenosis in both patients. No complications occurred during the procedures. At a mean follow-up of 878 ± 559 days no signs of in-stent restenosis or recoil were found. The present cases emphasize the feasibility and safety of CAJ stenting, underlining the importance of preserving CAJ and upper veins patency in hemodialysis access
Renal artery aneurysm. Treatment by ex vivo reconstruction and autotransplantation: three cases and literature review
Renal artery aneurysms (RAAs) is a rare clinical entity: the prevalence is approximately 0.01%-1% in the general population. Complex aneurysms of the first ramification of the main renal artery often require nephrectomy for adequate excision. From December 2002 to July 2007, we treated 3 patients with complex RAA. All the patients were treated with ex vivo reconstruction of the renal artery followed by autotransplantation of the kidney into the ipsilateral iliac fossa. Observation is suggested for asymptomatic complex renal artery aneurysms measuring less than 2 cm in diameter. Surgical treatment by aneurysmectomy and reconstruction in vivo or ex vivo technique is indicated for RAA causing renovascular hypertension, dissection, embolization, local expansion and for those in women of childbearing age with a potential for pregnancy, or asymptomatic more than 2 cm in diameter. Ex vivo repair and renal autotransplantation is a safe and effective treatment for the management of complex renal artery aneurysms
Fatal complication after Thrombin injection for post-catheterization femoral pseudoaneurysm
[Submandibulectomy in the treatment of pathology of the submandibular gland: our experience 1970-1995].
Submandibular gland excision is proposed in the treatment of neoplastic and non neoplastic diseases; this surgical procedure can be performed by transoral or transcervical approach. The aim of the study is to demonstrate that cervical approach must be preferred because it is safer and allows a wider exposition of the surgical field. From 1970 to June 1995, 54 patients (47 with chronic sialadenitis, 7 with benign tumors and 7 with malignant tumors) were submitted to excision of the submaxillary gland. Of the 54 resections performed, 2 were completed with "functional" cervical lymphadenectomy and 1 with Radical Neck Dissection in pts. with malignant neoplasms. There were no postoperative deaths; complications occurred in 1 patient (1/54 = 1.8%) as a iatrogenic permanent lesion of the maxillary branch of the facial nerve (in detail 0/47 patients with benign disease and 1/7 (14.7%) patients with malignant disease). The cervical approach for the resection of the submaxillary gland is preferred to the transoral approach for the lower risk of iatrogenic lesions of the lingual and hypoglossal nerves and the possibility of curative resections in case of malignant neoplasms. A regulated and experimented technique through the cervical approach also lowers the risk of a lesion of the maxillary branch of the facial nerve
Autotrapianto renale ex vivo negli aneurismi delle arterie renali. Analisi di tre casi e revisione della letteratura
Gli aneurismi complessi dell’arteria renale rappresentano certamente una patologia rara, con una prevalenza nella popolazione generale compresa tra lo 0,01 e 1%. Spesso il trattamento richiede un espianto del rene per una corretta ricostruzione, soprattutto quando sono coinvolti i rami dell’ arteria renale principale.
Dal dicembre 2002 al luglio 2007 abbiamo trattato 3 pazienti affetti da aneurisma complesso dell’arteria renale principale mediante autotrapianto ex vivo con aneurismectomia da banco e successivo reimpianto in fossa iliaca omolaterale. Noi riteniamo in accordo con la letteratura internazionale che aneurismi complessi richiedano la semplice osservazione qualora asintomatici e con diametro massimo inferiore a 2 cm. Aneurismi asintomatici con diametro maggiore di 2 cm, comunque sintomatici per disturbi urologici, ipertensione renovascolare, embolizzazione e quelli in età fertile richiedono un trattamento chirurgico.
Il trattamento extracorporeo dell’aneurisma dell’arteria renale con chirurgia da banco consente un buon risultato anche funzionale
