Background. To provide optimal nephron mass, two adult kidneys with suboptimal function can be transplanted into one single recipient. All techniques described to date are based on the lengthy sequential transplantation of one allograft after the other, in each iliac fossa, or through one long incision in the right iliac quadrant. Material and Methods. We report on a novel shorter and simpler operative technique allowing the en-bloc transplantation of seven dual adult kidneys with multiple vessels into a single iliac fossa, with revascularization through the donor aorta and vena cava. A proposal for the identification, allocation, procurement, and placement of the dual adult kidneys is presented. Results. There was no primary non-function, no thrombosis, and no urinary leakage. No urosepsis and hydronephrosis were noted during the follow-up. The operative time was 180 min. At 36 months, serum creatinine levels averaged 1.8 mg/dL (range 1.4–1.9 mg/dL). Conclusions. The procedure described permits converting two complex vascular kidneys into one en-bloc graft, which then can be transplanted into a single iliac incision, using only one arterial and one venous anastomoses. It avoids extensive dissection, shortens the operative time, and reduces the complications rate for the elderly recipients. It is applicable to the transplantation of dual kidneys with single or multiple arteries.

Abstract Background Pericardial hematoma is blood accumulation in the pericardial space. Although rare, it could arise in various conditions, such as after cardiac surgery. Clinical diagnosis of pericardial hematoma is implausible; thus, cardiac imaging plays a pivotal role in identifying this condition. We presented a case of multiple pericardial hematomas, which was found as an incidental finding in post-cardiac surgery evaluation. We highlighted the diagnostic challenge and the key features of multi-modality cardiac imaging in pericardial hematoma evaluation. Case presentation An asymptomatic, 35-years old male, who underwent surgical closure of secundum atrial septal defect (ASD) one month ago, came for routine transthoracic echocardiography evaluation. An intrapericardiac hematoma was visualized at the right ventricle (RV) 's free wall side. Another mass with an indistinct border was visualized near the right atrium (RA). This mass was suspected as pericardial hematoma differential diagnosed with intracardiac thrombus. Cardiac computed tomography (CT) scan showed both masses have an attenuation of 30–40 HU; however, the mass's border at the RA side was still not clearly delineated. Mild superior vena cava (SVC) compression and multiple mediastinal lymphadenopathies were also detected. These findings are not typical for pericardial hematomas nor intracardiac thrombus; hence another additional differential diagnosis of pericardial neoplasm was considered. We pursued further cardiac imaging modalities because the patient refused to undergo an open biopsy. Single-photon emission computer tomography (SPECT)/CT with Technetium-99 m (Tc-99 m) macro-aggregated albumin (MAA) and Sestamibi showed filling defect without increased radioactivity, thus exclude the intracardiac thrombus. Cardiac magnetic resonance imaging (MRI) reveals intrapericardial masses with low intensity of T1 signal and heterogeneously high intensity on T2 signal weighted imaged and no evidence of gadolinium enhancement, which concluded the diagnosis as subacute pericardial hematomas. During follow-up, the patient remains asymptomatic, and after six months, the pericardial hematomas were resolved. Conclusion Pericardial hematoma should be considered as a cause of pericardial masses after cardiac surgery. When imaging findings are atypical, further multi-modality cardiac imaging must be pursued to establish the diagnosis. Careful and meticulous follow-up should be considered for an asymptomatic patient with stable hemodynamic.

Thorough study is required to decide the appropriate management of hepatic tumors in children. We present a case report of a hepatic embryonal undifferentiated sarcoma with unfavorable prognosis in a nine-year-old girl. After undergoing a detailed cancer characteristics and extension study, a two-stage surgery approach was decided. The hepatic tumor resection was the first procedure to be performed. One week later, under cardiopulmonary bypass, deep hypothermia, and circulatory arrest, thrombectomy of the inferior vena cava and right atrium was accomplished, plus thromboendarterectomy of the right pulmonary artery. During a four-year follow-up, the patient continues to be disease-free.

Abstract Background Hyperactive dysfunction syndrome (HDS) refers to a constellation of symptoms developing from cranial nerve overactivity caused by neurovascular compression at the root entry or exit zone near the brainstem. Although the combined features of HDS are seen in the elderly, there are no reports of such cases in adolescents, to date. Case presentation A 17-year-old male was diagnosed with right glossopharyngeal neuralgia and treated with microvascular decompression. He experienced new-onset right facial pain later and was diagnosed with right trigeminal neuralgia, which required prompt radiofrequency thermocoagulation of the right mandibular nerve. Follow-up in the third post-treatment year revealed the absence of symptom recurrence. Discussion We report the treatment of a rare case of adolescent-onset combined HDS presenting as trigeminal and glossopharyngeal neuralgia. This report highlights the possibility of combined hyperactive dysfunction syndrome in younger age groups. It is crucial to establish a diagnosis early on for prompt management.

Urinary Metanephrines

Abstract Introduction: PPGLs are rare neuroendocrine tumors that arise from chromaffin cells of the adrenal medulla or their neural crest progenitors, being able to secrete catecholamines. Its treatment is primarily surgical; however, for metastatic/inoperable tumors, effective treatments are lacking. The use of TMZ, an oral alkylating agent, has been scarcely reported with variable response rates. We report 2 patients with reasonable clinical, biochemical and structural responses. Case Reports: Case 1) A 14-year old girl presented with neck pain, sweating, hypertension and tachycardia. Urinary hormonal profile revealed metanephrines 80 (up to 320 ug/24h) and normetanephrines 2983 (up to 390 ug/24h). Abdominal MRI showed a 10x6x5 cm retroperitoneal lesion in close contact with celiac trunk, superior mesenteric artery, renal arteries, aorta, left renal vein and vertebral bodies of T10, T11 and T12. A chest CT revealed multiple lung metastases. After 11 months, both the primary abdominal lesion and lung metastases increased in size.. Due to disease severity, after excluding surgical possibilities and confirming diagnosis by lesion biopsy, rescue treatment with TMZ was started for 5 days on a 28-day cycle. After 11 cycles, lung and abdominal lesions decreased more than 30% in size, and urinary metanephrines decreased 53.4%. After 21 cycles, there is no evidence of disease progression. Case 2) A 44-year old female was first diagnosed at the age of 31 with a right adrenal mass invading the kidney and the inferior vena cava associated with hypertension, sweating, headaches and palpitations. She underwent right adrenalectomy and nephrectomy. Immunohistochemistry confirmed the diagnosis of pheochromocytoma. Seven years later, follow-up CT`s showed a 3 x 2 cm liver metastasis, which was resected, and two lung lesions, one located at the right inferior lobe (1.6 cm) and the other at the left superior lobe (0.9 cm), which initially were just followed-up. At this time, a 7-month sorafenib trial was performed but the drug was stopped due to intolerable side effects. After 3 years of follow-up, the lung lesions increased in size and the right lesion was resected, but the patient refused surgery for the remainder left lung lesion. After 1 year, left lung lesion increased to 2.4 cm and mediastinal and paratracheal lymphadenomegaly developed. TMZ in the same aforementioned schedule was prescribed and after 7 cycles a new chest CT revealed complete regression of the lung and lymph node metastases.. Urinary metanephrines were 2.1 times the upper limit of normal before TMZ and decreased to normal range. Conclusion: These cases highlight the promising role of a well-tolerated single drug chemotherapy regimen in severe cases of metastatic and inoperable PPGLs. TMZ could be considered an alternative strategy for the treatment of these cases and, if possible, should be tested in adequate clinical trials.

Introduction. Milligan-Morgan haemorrhoidectomy performed with LigaSure system (LS) seems to be mainly effective where a large tissue demolition is required. This randomized study is designed to compare LigaSure haemorrohidectomy with conventional diathermy (CD) for treatment of IV-degree haemorrhoids. Methods. 52 patients with IV-degree haemorrhoids were randomized to two groups (conventional diathermy versus LigaSure haemorrhoidectomy). They were evaluated on the basis of the following main outcomes: mean operative time, postoperative pain, day of discharge, early and late complications. The time of recovery of work was also assessed. All patients had a minimum follow-up of twelve months (range 12–24). All data were statistically evaluated. Results. 27 patients were treated by conventional diathermy, 25 by LigaSure. The mean operative time was significantly shorter in LS, such as postoperative pain, mainly lower on the third and fourth postoperative day: moreover pain disappeared earlier in LS than CD. The time off-work was shorter in LS, while there was no difference in hospital stay and overall complications rate. Conclusions. LigaSure is an effective instrument when a large tissue demolition is required. This study supports its use as treatment of choice for IV degree haemorrhoids, even if the procedure is more expansive than conventional operation.

Purpose. This study aimed to retrospectively review the diagnosis and surgical treatment of uterine intravenous leiomyomatosis (IVL). Methods. The clinical data of 14 patients with uterine IVL admitted to our hospital between 2013 and 2018 were retrospectively analyzed, including their demographics, imaging results, surgical procedures, perioperative complications, and follow-up results. Results. The tumors were confined to the pelvic cavity in 7 patients, 1 into the inferior vena cava, 4 into the right atrium, and 2 into the pulmonary artery (including 1 into the superior vena cava). Only one case was misdiagnosed as right atrial myxoma before the operation, which was found during the surgery and was treated by staging surgery; all the other patients underwent one-stage surgical resection. Three patients underwent complete resection of the right atrial tumor through the abdominal incision, and one patient died of heart failure in the process of resection of heart tumor without abdominal surgery. During the 6–60 months of follow-up, 4 patients developed deep venous thrombosis of the lower extremity, and 1 patient developed ovarian vein thrombosis and pulmonary embolism. After anticoagulation treatment, the symptoms disappeared. One patient refused hysterectomy and the uterine fibroids recurred 4 years after the operation. Conclusion. Specific surgical plans for uterine IVL can be formulated according to cardiac ultrasound and computed tomography (CT). For the first type of tumor involving the right atrium, the right atrium tumor can be completely removed through the abdominal incision alone to avoid thoracotomy. The disease is at high risk of thrombosis and perioperative routine anticoagulation is required.

An 11 yr old spayed female Labrador retriever was diagnosed with a right adrenal tumor. At surgery, adhesions to the right kidney were dissected, allowing the right kidney to be preserved. The tumor showed extensive invasion into the suprarenal vena cava. It was felt that thrombus removal via venotomy could not be performed. Instead, the vena cava was ligated caudal to the liver and cranial to the right renal vein. The neoplastic gland was then excised en bloc together with the portion of the invaded caudal vena cava. Hind limb edema had developed preoperatively and increased transiently in the first days postoperatively. The animal was discharged 6 days postoperatively with no other clinical disorders, and hind limb edema resolved over time. Histopathology identified a pheochromocytoma. The dog died 49 mo later. A neoplastic thrombus of the vena cava may require venotomy to allow thrombus removal. Occasionally, removal of the thrombus by venotomy may prove impossible. In such a situation, en bloc removal of the concerned portion of the vena cava may be performed with a good long-term outcome provided that gradual occlusion of the vena cava by the thrombus has allowed time for collateral circulation to develop.

Laparoscopic varicocelectomy is suggested only for II-III grade bilateral varicocele. The optical magnification granted by videosurgical techniques, prevents damaging testicular arteries; this possibility, however, requires a considerable amount of time. We performed a laparoscopic “en-bloc” ligation without sparing the artery on 13 patients with bilateral varicocele in order to assess eventual changes in gonadal volume. 10 patients underwent bilateral “en-bloc” ligation of spermatic vessels with an average operating time of 21 minutes. In 3 other patients, “en-bloc” ligation was performed on the right side while on the left side the artery was identified and saved; in these cases the average operating time was 33 minutes. After an average follow-up period of 19 months no cases of testicle atrophy nor of hydrocele were reported. ColorDoppler sonography, performed 3 months later on the 10 patients treated by bilateral “en-bloc” ligation, showed no persistent reflux. No case of homolateral persistent reflux was encountered in the 3 patients who underwent only right-side “en-bloc” ligation, but on the left side, where selective ligation had been performed, persistence of reflux was registered in one patient. Our experience has confirmed that laparoscopic “en-bloc” ligation of the internal spermatic pedicle, sparing vasa deferentia, prevents the persistence of reflux in all cases and allows a reduction in operating time. The opportunity of treating a pathology like bilateral varicocele by means of laparoscopy, which requires general anaesthesia, needs further confirmation and a larger number of case histories.

Introduction. Situs inversus totalis (SIT) represents a total vertical transposition of the thoracic and abdominal organs which are arranged in a mirror image reversal of the normal positioning 1. We presented a successful pre-dialysis kidney transplantation from a living sibling donor with SIT and the longest donor follow-up period, along with analysis of the reviewed literature. Case report. The pair for pre-dialysis kidney transplantation included a 68-year-old mother and 34-year-old daughter at low immunological risk. Comorbidities evidenced in kidney donors with previously diagnosed SIT, included moderate arterial hypertension and borderline blood glucose level. Explantation of the left donor kidney and its placement into the right iliac fossa of the recipient were performed in the course of the surgical procedure. A month after nephrectomy, second degree renal failure was noticed in the donor. A 20-month follow-up of the donor?s kidney and graft in the recipient proved that their functions were excellent. Conclusion. In donors with previously diagnosed SIT the multidisciplinary approach, preoperative evaluation of the patient and detection of possible vascular anomalies are required to provide maximum safety for the donor.

Anomalous Pulmonary Venous Connection

Over the years, different techniques have been introduced for the repair of sinus venosus atrial septal defect (ASD) with anomalous right-sided pulmonary venous connection to the superior vena cava. We report the case of a 9- year-old girl, who presented with dyspnea and peripheral cyanosis. Preoperative echocardiography and angiography findings suggested a partial anomalous pulmonary venous connection. On cardiopulmonary bypass, the ASD was dilated, and the anomalous pulmonary vein was anastomosed to the right atrium and redirected to the left atrium using an intraatrial baffle and a tube graft. The intraoperative and postoperative periods were uneventful, and the patient is currently in good health at 4.5 years’ follow-up.
