Single-Center Experience with Simultaneous Mural Aortic Thrombosis and Peripheral Obstructive Disease in Pre-COVID-19 and COVID-19 Era.

BACKGROUND: Mural aortic thrombosis associated with chronic peripheral obstruction of the lower limbs is an unusual event. Repeated embolism of instability aortic mural thrombosis caused acute limb ischemia (Rutherford 2 classification) in patients with peripheral arterial disease (PAD). We report a single-center experience for patients with transmural aortic thrombosis and peripheral artery disease. METHODS: We retrospectively analyzed data of 54 patients with aortic mural thrombus disease with PAD presentation, treated at our center between 2013 and 2022. RESULTS: Thirty patients (six with proven SARS-CoV-2 infection) underwent hybrid or staged treatment for an aortic lesion and for lower limb ischemia, by the placement of an endovascular aortic stent graft and a femoro-distal or a popliteal-distal bypass graft. The remaining 24 cases were only subjected to an intravascular treatment of the thoracic or abdominal aorta. Transient renal failure occurred in three patients. No embolic events were detected during the procedures. Aortic-related mortality was reported in just one patient who died from multiple organ failure. There was an embolic stroke in one patient with proven SARS-CoV-2 infection, three major amputations in patients with proven SARS-CoV-2 infection and no aortic-related mortality. CONCLUSIONS: Stent coverage of complex aortic lesions, alone or in association with a distal bypass graft, supports this approach in a variety of settings. The COVID-19 pandemic caused an increased mortality and amputation rate.

Role of Contrast-Enhanced Ultrasound in the Follow-Up after Endovascular Abdominal Aortic Aneurysm Repair.

Background: The aim of this study was to assess whether contrast-enhanced ultrasound (CEUS) shows a false negative rate close to zero and therefore is suitable as the main non-invasive follow-up strategy for long-term monitoring after endovascular aortic repair (EVAR). Methods: We included all consecutive patients who underwent CEUS as follow-up after EVAR at our center between January 2017 and December 2021.The follow-up protocol consisted of Duplex ultrasound (DUS) with CEUS at 1, 3, 6 months postoperatively and every 6 months thereafter. Results: A total of 125 patients underwent 228 CEUS. The aneurysm sac showed shrinkage in 80 (64%) patients, stability in 32 (25.6%), and enlargement in 13 (10.4%). A total of 29 (23.2%) patients showed type 2 endoleak, 6 (4.8%) patients showed type 1 endoleak and 3 (2.4%) patients showed type 3 endoleak. Thirteen patients underwent one or more reinterventions. The sensitivity of CEUS vs. DUS was 100% vs. 75% (p > 0.0001). In classifying type 2 endoleak, CEUS compared to DUS showed a sensitivity of 93.2% vs. 59.4% and a specificity of 99.3% vs. 99.3%. CEUS showed a higher sensitivity compared to DUS in the detection of type 2 endoleak. CEUS permits the identification of a subset of patients requiring a stricter follow-up protocol.

Unusual attempted suicide or covered attempted homicide? A neck stabbing case report and review of literature.

A medico-legal consult is frequently required in a clinical context in order to assess the eventual compatibility of specific wounds with a self- or hetero-infliction. Accordingly, the case of a 52-year-old man with a single, penetrating stab wound of the neck, reported as self-inflicted, is here presented. The forensic aspects, taken into account in order to determine the self- or hetero-infliction nature of the wound, are further discussed and compared to cases described in the literature.

Intra-Arterial Administration of Iloprost in Patients Undergoing Endovascular or Hybrid Revascularization Procedures for Peripheral Arterial Disease.

BACKGROUND: The aim of this study was to find out if intra-arterial intraoperative iloprost administration, in selected patients undergoing endovascular revascularization procedures, could lead to better results compared with a control group of patients with similar clinical background and risk factors. METHODS: We prospectively collected data of consecutive patients undergoing endovascular or hybrid revascularization in the period from June 2017 to August 2019, which were then retrospectively analyzed. Those patients were divided into 2 groups: iloprost and control groups. Inclusion criteria were as follows: the presence of an arteriography that included the foot; Rutherford class 4-6; and Rutherford class 3 with at least 2 cardiovascular risk factors or previous revascularization procedures on the same limb. The intraoperative intra-arterial administration of iloprost was the inclusion criterion for the iloprost group. Patients with a compromised cardiological condition were excluded, as this was a contraindication for iloprost administration. Patients from the 2 groups were matched using the propensity score matching (PSM) methodology of Rosenbaum and Rubin. The primary outcome was freedom from target lesion revascularization (TLR). The secondary outcomes were limb salvage and overall survival. RESULTS: During the mentioned period, we treated 190 consecutive limbs. The mean follow-up was 11.73 months (median, 10; interquartile range, 5-19). After PSM, the freedom from TLR was significantly better in the iloprost group (78 ± 7%, 74 ± 8%, and 63 ± 9% vs. 67 ± 8%, 50 ± 9%, and 38 ± 10% at 3, 6, and 12 months, respectively; P = 0.043). No significant difference was found in terms of limb salvage (92 ± 5%, 88 ± 6%, and 88 ± 6% vs. 92 ± 4%, 85 ± 6%, and 81 ± 7% at 3, 6, and 12 months, respectively; P = 0.52) and survival (95 ± 3%, 95 ± 3%, and 95 ± 3% vs. 95 ± 4%, 92 ± 5%, and 71 ± 9% at 3, 6, and 12 months, respectively; P = 0.14) between the 2 groups. CONCLUSIONS: These results seem to encourage considering intraoperative use of this adjunct, at least in endovascular revascularization procedures, to improve distal outflow.

Feasibility and accuracy in performing complete mesocolic excision during laparoscopic left colectomy.

Laparoscopic colorectal surgery for cancer is nowadays performed in several referral centers and has been gaining increasing interest for treatment of colo-rectal cancer. After the introduction of complete mesorectal excision for rectal cancer, complete mesocolic excision has been advocated as an essential surgical step to improve oncologic results for patients with colon cancer. Complete mesocolic excision is a crucial step of hemicolectomy, and consists in the total removal of the mesocolon and its lymph nodes with high ligation of main mesenteric arteries and veins. In laparoscopic surgery, magnification of the images and gas dissection might probably improve the precision and safety of this surgical step. In this paper, the Authors reviewed the Literature and discussed on the feasibility and accuracy of complete mesocolic excision performed during laparoscopic left colectomy for cancer in a preliminary series. KEY WORDS: Colic lymph nodes, Laparoscopic left hemicolectomy, Mesocolon excision.

Late results after splenectomy in adult idiopathic thrombocytopenic purpura.

BACKGROUND: We performed a retrospective study on patients with idiopathic thrombocytopenic purpura (ITP) to evaluate the response to splenectomy in relation to preoperative platelet count. MATERIALS AND METHODS: Two groups of patients operated on with laparoscopic or open splenectomy for ITP, with a platelet count ≤30,000/µL (study group: 22 patients) and >30,000/µL (control group: 18 patients), respectively, were compared. The two groups were homogeneous in relation to age, sex, length of preoperative steroid therapy, and time interval between diagnosis and surgery (Student t test with P > .1). The results of surgery were evaluated at one year after splenectomy. Positive response to surgery, according to the American Society of Hematologic Guidelines, was considered in patients with a postoperative platelet count ≥100,000/µL or in patients with a postoperative platelet count ≥30,000/µL and a twofold increase in platelet count from baseline, in the absence of bleeding. The postoperative platelet count increase rate was statistically related to preoperative platelet count in both the study and control groups. Statistical analysis was performed using the Student's t test for independent sample and the Pearson correlation in a 2-tailed test. RESULTS: No relationship between preoperative platelet count and postoperative platelet percent increase was observed in the control group (r = -0.41; P = .089), whereas a significant negative correlation (r = -0.68; P = .0004) was found in the study group. CONCLUSIONS: A higher increase of postoperative percent platelet count may be predicted in patients with a low preoperative platelet count.

Laparoscopic splenectomy coupled with laparoscopic cholecystectomy.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the results of laparoscopic surgery performed for coexisting spleen and gallbladder surgical diseases. METHODS: Between May 2004 and October 2012, 12 patients underwent concomitant laparoscopic splenectomy and cholecystectomy. Indications for surgery included idiopathic thrombocytopenic purpura in 5 patients, hereditary spherocytosis in 4 patients, and thalassemia intermedia in 3 patients. RESULTS: The mean operative time was 100 minutes (range, 80 -160 minutes), and the blood loss ranged from 0 to 150 mL (mean, 50 mL). The mean longitudinal diameter of the spleen was 14 cm. One patient required conversion to open procedure. An accessory spleen was detected and removed in one case. The mean length of hospital stay was 5 days. No deaths or other major intraoperative and/or postoperative complications occurred. CONCLUSION: Provided that the technique is performed by an experienced surgical team, concomitant laparoscopic splenectomy and cholecystectomy is a safe and feasible procedure and may be considered for coexisting spleen and gallbladder diseases.
