Anastomotic Line

Anastomotic pseudoaneurysm remains one of the main life-threatening complications of cardiac and thoracic aorta surgery. We report a rare case of infected pseudoaneurysm at the anastomotic line found during follow-up. Blood culture results suggested Enterococcus faecium infection. Transthoracic echocardiography and computed tomography scans revealed the presence of a pseudoaneurysm of the ascending aorta. The pseudoaneurysm was resected and the ascending aorta was reconstructed with an artificial vascular patch without complications. Reducing the anastomotic tension, with complete hemostasis at the anastomotic incision, is the most important means of preventing the formation of pseudoaneurysm.

We reported a rare case of spontaneous frank rupture of a small (4 mm) penetrating aortic ulcer in the ascending aorta resulted in catastrophic bleeding. The ulcer only created a pinhole wound in the adventitia without saccular aneurysms, intramural hematomas, or aortic dissections. Notably, the wound could be directly closed because the aortic wall was intact only 5 mm away from the bleeding site. The postoperative course was uneventful, and the patient was discharged on the 11th postoperative day. After 8 months, follow-up computed tomography showed no abnormality of the aortic wall at the repair site.

Pseudocyst Formation

Despite its numerous benefits, peritoneal dialysis (PD) can rarely result in dangerous and even life-threatening complications, including peritonitis, hernias, encapsulating peritoneal sclerosis (EPS), and rarely peritoneal pseudocysts. Herein, we present a rare case of a giant intra-peritoneal pseudocyst that presented four months following the discontinuation of a 5-year course of complicated PD. Despite the initially successful drainages, the patient’s symptoms continued to recur, and the imaging findings were concerning for underlying neoplastic processes. As such, a staged surgical approach was performed, starting with a diagnostic laparoscopy and was subsequently followed with cyst excision and marsupialization to the peritoneal cavity. While previous reports of such rare pseudocyst have been documented in the literature as a complication of PD, to our knowledge, this is the second case of pseudocyst formation to occur months after the discontinuation of PD therapy. This case emphasizes the importance of close follow-up in PD patients and showcases how a staged surgical approach can be utilized to accurately diagnose and manage such complicated cases.

We report our experience with the repair of the orbital floor fractures and present new technical findings. We evaluated 30 subjects with pure blowout fractures treated at the Department of Maxillofacial Surgery of the Federico II University of Naples, Italy, between 2005 and 2007. A preoperative examination by computed tomography scans provided classification of the orbital floor fractures into small and large fractures by measurement of the bone defect to choose the appropriate reconstructive implant materials, resorbable or nonresorbable. The clinical follow-up has been performed at 1 week, 1 month, 3 months, and 6 months. We observed a resolution of preoperative symptoms. The scar was not evident, and there was an absence of postoperative complications. We concluded that the use of resorbable materials for small orbital floor fractures and nonresorbable materials for large orbital floor fractures offers satisfactory results in both functional and aesthetic considerations. Furthermore, the new technical findings allow standardization of the surgical technique to be more accurate, also reducing the economic costs.

Although an ascending aortic thrombus is a rare condition, it can cause serious complications of thromboembolism. Here we present a rare case of a patient who was hospitalized due to ileal arteries embolization caused by emboli from a giant thrombus in the ascending aorta. After 10 days anti-coagulation therapy, we performed a surgery to replace the ascending aorta containing the strip organized thrombus with a synthetic graft. During two years of postoperative follow-up, no recurrence of aortic thrombosis was found. Although the exact cause of this thrombus remains unclear, we believe that it is important to perform a surgery as soon as the presence of an ascending aortic thrombus is confirmed, which could help preventing the major recurrent embolic events.

Pancreatic Head Tumor

There have been no reports of ruptured solid pseudopapillary neoplasm (SPN) into adjacent organs. A 22-year-old female was referred to our hospital for treatment of a pancreatic head tumor. Computed tomography (CT) examination at our hospital showed a 5-cm tumor containing air, although CT at a previous hospital revealed an 8-cm tumor without air. Thus, a spontaneous rupture of the tumor into the duodenum was suspected. Subtotal stomach preserving pancreaticoduodenectomy with combined resection of the portal vein was performed. Contrast radiography of resected specimen showed the medium injected into the tumor leaking out from the 2nd portion of the duodenum. Histologically, the patient was diagnosed as SPN. Microscopic invasion to the portal vein and duodenum were also confirmed. She did not experience any postoperative complications and has remained well without any signs of recurrence during 2 years of follow-up. Although there have been 14 studies reporting ruptured SPN, this is the first report of SPN that spontaneously ruptured into the duodenum. An extremely rare case of SPN of the pancreatic head that spontaneously ruptured into the duodenum was reported.

Paragangliomas can be found from the skull base to the sacrum. Sinonasal paragangliomas are infrequent. A 16-year-old female reported spontaneous discrete bilateral epistaxis once a month beginning when she was 3 years of age. Computed tomography showed an expansive hypervascular mass occupying the right nasal cavity and nasopharynx. Sinonasal paragangliomas usually occur in middle-aged women. Radiologic investigation is essential for the diagnosis of sinonasal paragangliomas and evaluating extension of the lesion. Endoscopic and conventional approaches are effective, and preoperative embolization is paramount for reducing bleeding risk. Histopathological features cannot differentiate benign from malignant paragangliomas, and since metastasis may eventually occur, follow-up must be carried out for a long period of time.

Abstract BACKGROUND: Reconstruction of the thoracolumbar spine after corpectomy is a challenge for fractures, infections, and tumors. OBJECTIVE: To analyze fusion rates, clinical outcomes, and the percent of vertebral body coverage achieved by using stackable carbon fiber–reinforced polyetheretherketone cages in thoracolumbar corpectomies, and to measure the actual size of the cages and compare this measurement with the size of the vertebra(e) replaced by the cage. METHODS: A retrospective study of 40 patients who underwent thoracolumbar corpectomies was performed. Preoperative imaging included plain films, computed tomography scans, and magnetic resonance imaging. Postoperatively, plain films and computed tomography scans were obtained, and the width of decompression and cross-sectional area of the cage were measured. The ratio of the area of the cage to the calculated area of the replaced vertebral body was used to determine the percent of vertebral body coverage. RESULTS: The mean follow-up period was 43 months. Successful fusion was observed in 39 patients. One patient experienced cage subsidence with kyphosis. One additional patient incurred a neurological complication that was corrected without long-term consequence. The mean correction of sagittal alignment was 10°, and the mean width of bony decompression was 20 mm. The mean ratio of the area of the carbon fiber cage to the area of the resected vertebral body was 60%. CONCLUSION: Stackable carbon fiber cages are effective devices for achieving thoracolumbar fusions. No failures of the cages occurred over long-term follow-up. Excellent clinical and radiographic results were achieved by covering a mean of 60% of the vertebral body with the cage.

Ravitch technique of chest correction has been considered, although invasive, as safe and efficacious surgical method. We describe a case of 35-year-old woman with cardiac tamponade and in cardiogenic shock due to exceptional late complication after pectus excavatum reconstruction by means of classic Ravitch technique 19 years earlier. This very late adverse event was caused by broken metal sternal wire that injured the wall of the ascending aorta. Patient underwent salvage repair of this segment of aorta in cardiopulmonary bypass. Postoperative course and post-discharge 3-year follow-up have been uneventful.

Abstract Background Aneurysmal degeneration of the coronary button after aortic root replacement using the button technique is a rare but potentially life-threatening complication. However, the appropriate management of this complication, including the indications for conservative and surgical treatment, is still unknown. Case presentation Here we present a 38-year-old woman who successfully underwent surgical repair of a left coronary button aneurysm using the graft interposition technique 24 years after aortic root replacement. Because follow-up computed tomography after aortic root replacement showed a progressively enlarging left coronary button aneurysm, the patient was judged an acceptable candidate for surgical treatment, considering the potential risk of aneurysmal rupture and subsequent myocardial infarction. The postoperative recovery was uneventful. The patient is doing well 1 year after the surgery. Conclusions We believe that serial follow-up using computed tomography is mandatory for coronary button aneurysms, and surgical intervention may be considered if progressive enlargement of the aneurysm is observed, especially in younger patients.
