Usefulness of image guidance in the surgical treatment of petrous apex cholesterol granuloma

The petrous apex is a pyramid-shaped structure, located medial to the inner ear and the intrapetrous segment of the internal carotid artery. Lesions of the petrous apex can be surgically treated through different surgical routes. Because of the important neurovascular structures located inside the temporal bone, anatomical 3D knowledge is paramount. For this reason, image-guided surgery could represent a useful tool. We report the case of a young woman who came to our observation for a trigeminal neuralgia due to a petrous apex cholesterol granuloma. The lesion was treated through the placement of a drainage tube via an infracochlear approach, with the aid of neuronavigation and intraoperative MRI. Preoperative CT scan images and intraoperative MRI images were fused for surgical planning. The accuracy of the neuronavigation system has proved to be good, and the safety of the procedure was enhanced. Therefore, neuronavigation and intraoperative MRI, though not available in all neurootological centres, should be considered useful tools in these challenging procedures

acute occlusion of descending thoracic aorta

Acute aortic occlusion is a rare but potentially devastating clinical event, which requires a prompt diagnosis and emergency treatment. Only 5 cases of native thoracic aorta acute occlusion have so far been reported with different pathologic causes. The clinical features depend on the level of occlusion. Sometimes the diagnosis could be misinterpreted as a stroke or other diseases of the central nervous system. This could lead to a delay in the diagnosis and revascularization procedure, followed by a morbidity or mortality increase. Open surgery has been considered the first-line approach. This study is of a female patient suffering from acute descending thoracic aorta occlusion undergoing, for the first time to our knowledge, endovascular surgical treatment

Laparoscopic repair for perforated peptic ulcer: our experience, a comparison with the open approach and a review of the literature.

Backgrounds: The incidence of perforated peptic ulcers has decreased during the last decades but the optimal treatment for these patients remains controversial. At the same time, a laparoscopic approach to this condition has been adopted by an increased number of surgeons. Therefore, this study wants to evaluate the postoperative results of the laparoscopic treatment of perforated peptic ulcer performed in one Italian center with extensive experience in laparoscopic surgery. Methods: This retrospective study includes 94 patients who were operated for perforated peptic ulcer peritonitis at “St. Orsola Hospital - Emergency Surgery Unit - University of Bologna” from May 2014 to December 2019. The patients’ charts were reviewed for demographics, surgical procedure, complications, and short-term outcomes. Results: The diagnosis was made clinically and confirmed by the presence of gas under diaphragm on abdominal X-ray. All patients underwent primary suture repair with or without omentopexy. Boey score 0 or 1 was found in 66 (70%) patients, Boey 2 or 3 in 28 (30%) patients. The operative time was between 35 and 255 minutes, with a mean of 93 minutes. The overall median hospital stay was 9.5 (1-60) days. Post-operative complications occurred in 19 (20%) patients and 18 (19%) patients died. Conclusions: Perforated peptic ulcer is a severe condition that requires early hospital admission and immediate surgery. Laparoscopy in experienced centers and for selected patients is safe, associated with optimal outcomes and should be the preferred approach

Transcatheter Aortic Valve Implantation: The New Challenges of Cardiac Rehabilitation

Transcatheter aortic valve implantation (TAVI) is an increasingly widespread percutaneous intervention of aortic valve replacement (AVR). The target population for TAVI is mainly composed of elderly, frail patients with severe aortic stenosis (AS), multiple comorbidities, and high perioperative mortality risk for surgical AVR (sAVR). These vulnerable patients could benefit from cardiac rehabilitation (CR) programs after percutaneous intervention. To date, no major guidelines currently recommend CR after TAVI. However, emerging scientific evidence shows that CR in patients undergoing TAVI is safe, and improves exercise tolerance and quality of life. Moreover, preliminary data prove that a CR program after TAVI has the potential to reduce mortality during follow-up, even if randomized clinical trials are needed for confirmation. The present review article provides an overview of all scientific evidence concerning the potential beneficial effects of CR after TAVI, and suggests possible fields of research to improve cardiac care after TAVI

Liver Cirrhosis Patients Homozygous for MTHFR C677T Develop Portal Vein Thrombosis 8 Years Earlier Than Wild Type

Background and Aim Age at portal vein thrombosis (PVT) in liver cirrhosis (LC) carriers of the methylene tetrahydrofolate reductase (MTHFR) rs1801133 (C -> T667 transition) polymorphism has never been addressed; we compared age at PVT in LC patients genotyped for the MTHFR and explored the interrelated clinical and laboratory factors predicting age at PVT. Approach and Results Retrospective cross-sectional cohort study. PVT participants: MTHFR CC n = 36, MTHFR CT n = 53, MTHFR TT n = 19; age, sex, age at PVT, Child-Pugh score, rs1799963 PT polymorphisms (G -> A 20,210 transition), plasma HC and natural anticoagulants available for all participants. Age at PVT was lower in MTHFR TT than CT and CC (56 +/- 13 vs. 57 +/- 13 vs. 64 +/- 9 years, p = 0.001); median (IQR) plasma HC was higher in MTHFR TT than in the other groups [(17 (9.4, 23.3) vs 13 (8,14.7) vs 11 (8.9, 12.7) mu mol/l, p = 0.03)]. MTHFR TT, male gender and protein C predicted age at PVT (p = 0.02, p = 0.04 and p = 0.08); MTHFR TT and Child-Pugh score predicted plasma HC (p = 0.005 and p = 0.01) as well as low plasma protein C (p < 0.0001 and p = 0.0002). Plasma HC inversely related to protein C in the MTHFR TT group (p < 0.0001). Compound MTHFR TT with PT GA had lower age at PVT compared to MTHFR TT alone (49 +/- 18 vs 58 +/- 12 years). Conclusions MTHFR TT anticipates PVT associated with LC by an average of 8 years; MTHFR TT associates with severity of liver disease and to high plasma HC; the latter may contribute to the prematurity of PVT by interfering with the anticoagulant activity of protein C
