We report the case of a 65-year-old male patient who was deemed unfit for open surgery and underwent zone 0 endovascular repair with a physician-modified fenestrated endograft for a symptomatic penetrating ulcer. A thoracic stent graft was modified creating a large fenestration for the innominate artery and the left common carotid artery, and a second small fenestration for the left subclavian artery and the left vertebral artery, which had a common origin. No bridging stent was used for the left subclavian artery to avoid coverage of the left vertebral artery. The postoperative course was uneventful, and no leaks nor other complications were detected on postoperative computed tomography angiography. Although long-term durability needs to be better assessed, our experience suggests that physician-modified fenestrated endografts are a feasible option for the emergent treatment of aortic arch lesions in unfit patients and provide satisfactory results in the short term.

An 82-year-old man with a secundum atrial septal defect (ASD) underwent transcatheter closure. The patient had a wide area of aortic and superior rim deficiency, with left ventricular diastolic dysfunction and moderate mitral regurgitation. These findings suggested the risk of both cardiac erosion and increased left atrial pressure after closure. To avoid cardiac erosion, a GORE® CARDIOFORM ASD (GCA) occluder (W.L. Gore & Associates, Flagstaff, AZ, USA) was considered an appropriate device in this patient. However, the possibility of excessively high left atrial pressure due to complete defect closure was a concern. Thus, we created a 4.5-mm fenestration using a surgical punch in the fabric membrane of a 44-mm GCA. The device was deployed in an appropriate position, and no significant elevation of pulmonary capillary wedge pressure was observed. One month after the closure, marked improvement in clinical symptoms and continuous flow through the fenestration were observed. This novel fenestration technique may contribute to expansion of the indications for transcatheter ASD closure in patients who require a GCA owing to an anatomically high risk of erosion accompanied by left ventricular diastolic dysfunction.
UNASSIGNED: In elderly patients with left ventricular diastolic dysfunction, transcatheter atrial septal defect (ASD) closure is difficult because rapid resolution of an ASD shunt can cause an increase in left atrial pressure. Previous reports described the creation of a fenestration in the closure device. The use of a GORE® CARDIOFORM ASD (GCA) occluder can reduce the erosion risk; however, creating a stable fenestration is difficult. We developed a novel technique to create a stable fenestration in a GCA.

The presence of facial jewelry and medical devices within a radiographic field of view may promote the formation of artifacts that challenge diagnostic interpretation. The objective of this article is to describe a previously unreported radiographic anomaly produced by an oral piercing site below the lower lip. This unusual artifact masqueraded as a severe resorptive defect, dental caries, or cervical abfraction and occurred following removal of an extremely large labret below the lower lip and subsequent acquisition of a radiographic image. The radiolucency was ultimately attributed to an extensive aperture below the lower lip created by a series of sequentially larger soft tissue expanders. Clinicians should seek correlation of atypical radiographic presentations with soft tissue defects secondary to injury or intentional oral piercing.

Anastomosis of the prosthetic graft to the double-barreled aorta with intimal flap fenestration is a useful technique in surgery for chronic aortic dissection. Conversely, anastomosis to the false lumen\'s outer wall is prone to complications such as pseudoaneurysms, but little is known about the technique of reinforcing the double-barreled aorta. In this report, we describe a surgical case of chronic aortic dissection in which an H-shaped prosthetic graft was sutured to both aortic lumens, including the intimal flap, to prevent complications at the anastomosis site.

UNASSIGNED: Thoracic endovascular aortic repair (TEVAR), originally conceived for deployment distal to the left subclavian artery (LSA), has been recently extended to more proximal landing zones. Among total endovascular solutions, the \"Canaud technique\" for Physician-Modified Thoracic Endovascular Grafts (C-PMEGs) has gained acceptance with good early results. The aim of this study is to report the proportion of patients with zone 0, 1, and 2 aortic arch lesions that could theoretically be treated with a C-PMEG.
UNASSIGNED: Computed tomography angiography (CTA) of all consecutive patient candidates to open, hybrid, or endovascular arch repair from January 2009 to July 2023 at our Institution were analyzed. The assessment of feasibility of C-PEMG was conducted following previously extensively described anatomical criteria.
UNASSIGNED: During the study period, 209 consecutive patients were candidates for an open, hybrid, or endovascular aortic arch repair. Of them, 164 patients had a preoperative CTA scan eligible for analysis. One hundred twenty-six patients were male (76.8 %), with a mean age of 67 ± 10.8 years. Ninety-four patients (57.3%) were affected by atherosclerotic aneurysms, 48 post-dissecting aneurysms (29.3%) and 22 penetrating aortic ulcers (PAUs) (13.4%). Twenty patients (12.2%) were suitable for double-fenestrated C-PMEG, and 34 patients (20.7%) for single-fenestrated C-PMEG, totaling 32.9% of the entire cohort. The combination of supra-aortic trunks (SAT) bypass or the use of covered stent in IA or left common carotid artery (LCCA) as adjunctive maneuvers, would extend the C-PMEGs feasibility to 69 patients (42.1%). The use of an iliac graft conduit in 3 (1.8%) patients with inadequate ileo-femoral accesses would increase the C-PMEG suitability to 72 patients (43.9%). The main reason for exclusion was excessive ascending aortic diameter in 78 patients (47.6%).
UNASSIGNED: The use of C-PMEG was shown to be theoretically feasible in a percentage of patients ranging from 32.9 to 43.9% affected by aortic arch aneurysms, dissections, and PAU. The main reason for exclusion was the dimension of the ascending aorta. The C-PMEG technique is a viable option in aortic arch lesions endovascular treatment. An off-the-shelf device with similar characteristics could also be used in emergency, avoiding the limitations of physician modifications (such as time for back-table procedure, sterility, off-label use).
CONCLUSIONS: Thoracic endovascular aortic repair (TEVAR) has been extended to more proximal landing zones for the treatment of aortic arch aneurysm, dissections, penetrating aortic ulcers. Among total endovascular solutions, the \"Canaud technique\" for Physician-Modified Thoracic Endovascular Grafts (C-PMEGs) has gained acceptance with good early results. The anatomical feasibility in 164 consecutive patients was 69 patients (42.1%), with the combination of supra-aortic trunks (SAT) bypass or the use of covered stent in IA or left common carotid artery (LCCA) as adjunctive maneuvers, showing that the C-PMEG technique is a viable option in aortic arch lesions endovascular treatment.

OBJECTIVE: The traditional treatment of sellar Rathke cleft cysts (RCCs) generally involves transsellar drainage; however, suprasellar RCCs present unique challenges to appropriate management and technical complexity. Reports on overall outcomes for the endoscopic endonasal approach (EEA) for this pathology are limited. The EEA for RCCs allows three surgical techniques: marsupialization, fenestration, and fenestration with cyst wall resection.
METHODS: The authors performed a retrospective review of consecutive patients with RCCs that had been treated via an EEA at a single institution between January 2004 and May 2021. Marsupialization entailed the removal of cyst contents while maintaining a drainage pathway into the sphenoid sinus. Fenestration involved the removal of cyst contents, followed by separation from the sphenoid sinus, often with a free mucosal graft or vascularized nasoseptal flap. Cyst wall resection, either partial or complete, was added to select cases.
RESULTS: A total of 148 patients underwent an EEA for RCC. Marsupialization or fenestration was performed in 88 cases (59.5%) and cyst wall resection in 60 (40.5%). Cysts were classified as having a purely sellar origin (43.2%), sellar origin with suprasellar extension (37.8%), and purely suprasellar origin (18.9%). Radiological recurrence was demonstrated in 22 cases (14.9%) at an average 39.7 months\' follow-up (median 45 months, range 0.5-99 months), including 13 symptomatic cases (8.8%). Cases with cyst wall resection had no significantly different rate of recurrence (11.7% vs 15.9%, p = 0.48) or postoperative permanent anterior pituitary dysfunction (21.6% vs 12.5%, p = 0.29) compared to those of fenestrated and marsupialized cases. There was no significant difference in postoperative permanent posterior pituitary dysfunction based on technique, although such dysfunction tended to worsen with cyst wall resection (13.6% vs 4.0%, p = 0.09). Based on cyst location, purely suprasellar cysts were more likely to have a radiological recurrence (28.6%) than sellar cysts with suprasellar extension (12.5%) and purely sellar cysts (9.4%; p = 0.008). Most notably, of the 28 purely suprasellar cysts, selective cyst wall resection significantly improved the long-term (10-year) recurrence risk compared to fenestration alone (17.4% vs 80.0%, p = 0.0005) without any significant added risk of endocrinopathy.
CONCLUSIONS: Endoscopic endonasal marsupialization or fenestration of sellar RCCs may be the ideal treatment strategy, whereas purely suprasellar cysts benefit from partial cyst wall resection to prevent recurrence. Selective cyst wall resection reduced long-term recurrence rates without significantly increasing rates of hypopituitarism.

Laparoscopic fenestration is the preferred treatment for symptomatic splenic cysts because it is curative and spleen-sparing. We report a case of a 25-year-old female who underwent laparoscopic fenestration for a giant splenic cyst using a single-incision plus one-port approach. She presented to our hospital with repeated vomiting. Imaging showed a 23 × 18 cm splenic cyst with no solid components, strongly compressing the stomach to the right side. Laparoscopic fenestration was initiated through a 2.5-cm umbilical incision, and a 5-mm port was added in the left abdomen intraoperatively. The drain placement was deemed necessary to prevent abscess formation and post-operative bleeding because of a thick cyst component and unexpectedly thick wall. Splenic cysts are typically benign and commonly develop in young people, hence, organ preservation and cosmetic results are crucial. Laparoscopic fenestration using single-incision plus one-port is considered to be an appropriate procedure for giant splenic cysts with non-serous contents.

OBJECTIVE: The study intends to clarify the optimal endoscopic endonasal surgical strategy for symptomatic Rathke\'s cleft cysts (RCCs).
METHODS: We retrospectively analyzed patients with RCCs that underwent EEA surgery. The strategy for surgical and reconstruction method selection was presented. Patients were split into groups of fenestration open or closed. Pre- and postoperative symptoms, imaging, ophthalmologic, and endocrinologic exams were reviewed. The incidence of complications and the recurrence rates were determined.
RESULTS: The 75 individuals were all received primary operations. The fenestration closed group contained 32 cases, while the fenestration open group contained 43 cases. The median follow-up period was 39 months. The three primary complaints were headache (n = 51, 68.00%), vision impairment (n = 45, 60.00%), and pituitary dysfunction (n = 16, 21.33%). Of the 51 patients with preoperative headaches, 48 (94.12%) reported improvement in their symptoms following surgery. Twenty-three out of 45 patients (51.11%) experienced an improvement in visual impairment. Pituitary dysfunction was found improved in 14 out of 16 individuals (87.50%). There was no discernible difference in the rate of symptom alleviation between both groups. There were three patients (3/75, 4.00%) had cyst reaccumulation. One of them (1/75, 1.33%), which needed reoperation, was healed using pterional approach. In term of complications, cerebral infections occurred in two patients (2/75, 2.67%). Both of them recovered after antibiotic treatment. No postoperative cerebrospinal fluid rhinorrhea occurred. One patient (1/75, 1.33%) in the open group experienced epistaxis. There was no persistent hypopituitarism or diabetes insipidus (DI). Analysis of headache related factors showed that the presence of wax like nodules was related to it.
CONCLUSIONS: RCC was successfully treated with endoscopic endonasal surgery with few problems when the fenestration was kept as open as feasible. Preoperative identification of T2WI hypointense nodules may be a potential reference factor for surgical indication.

OBJECTIVE: To examine the effects of buccal bone fenestration on maxillary anterior implants.
METHODS: Patients who underwent implant placement in the maxillary anterior region between January 2017 and December 2021 and had received final restorations 1 to 6 years prior were screened for inclusion in the present study. Propensity score matching was used to match the two-group sample size and reduce the influence of potential confounding factors. Generalised linear mixed models were employed to evaluate the correlation between buccal bone fenestration and peri-implant marginal bone loss.
RESULTS: A total of 42 patients with 50 implants were included in the study, 16 of whom had buccal bone fenestration (group 1) and 26 of whom did not (group 2). No implant failures occurred, resulting in a cumulative implant survival rate of 100.0%. There was no statistically significant difference between the pink aesthetic scores for the two groups. The mean marginal bone loss was 0.44 ± 0.46 mm for group 1 and 0.33 ± 0.32 mm for group 2 (P > 0.05). Buccal bone fenestration was not the influencing factor of marginal bone loss (P > 0.05). Marginal bone loss was greater around implants used to replace canines than those inserted to replace central incisors (P < 0.05). Far less marginal bone loss occurred around immediately loaded implants than delayed implants with cover screws (P < 0.05). When there is sufficient keratinised mucosa around the implant, marginal bone loss will decrease significantly (P < 0.05).
CONCLUSIONS: Within the limitations of this study, buccal bone fenestration defects around dental implants cannot influence peri-implant bone loss.
BACKGROUND: The authors report no conflicts of interest relating to this study.
