RESUMEN

INTRODUCTION: Hypothenar hammer syndrome is a rare cause of upper extremity digital ischemia or Raynaud phenomenon, a diagnosis which should be considered in cases of iterative palmar trauma. Its treatment can be medical or surgical and should not suffer any delay. The best options remain controversial. METHODS: A 65-year-old patient presented with an ischemia of the last three fingers of the left hand. A partially thrombosed aneurysm of the left ulnar artery was diagnosed at imaging. After a partially effective medical treatment, a surgical treatment was performed with resection of the aneurysm and a vascular reconstruction with an autologous vein graft. The postoperative course was uneventful with disappearance of the symptoms and revascularization of the hypothenar area. CONCLUSION: Appropriate treatment for hypothenar hammer syndrome is controversial but whould always begin with medical care. The decision to perform surgery should be based on evidence of ulnar artery lesions and the associated symptoms.

RESUMEN

Persistent blood flow in aneurysmal sac after bypass-exclusion is well documented in the literature. Aneurysm enlargement, local compressive symptoms and even sac rupture are commonly described complications. Late secondary infection of popliteal artery aneurysm (PAA) following ligation and venous bypass is exceptional. We report the case of late PAA infection six years after bypass-exclusion in a 75 year-old man which was diagnosed by 18F-FDG PET/CT. The patient was successfully treated by aneurysm resection and antibiotics. The diagnosis of popliteal aneurysm infection is often clinical, echographic and sonographic, but computed tomography scan can be false negative in chronic low-grade infection. 18F-FDG PET/CT is able to accurately diagnose and localize infection with high sensibility and specificity.

RESUMEN

Thyroid metastasis of solid tumors is rare and often asymptomatic. Differential diagnosis with malignant thyroid tumor is difficult. We report a 65-year-old man who presented with a solitary intrathoracic thyroid nodule of the left lobe, inaccessible to fine needle biopsy. His past medical history was remarkable for a nephrectomy for a kidney clear cell carcinoma one year before. The PET-scan did not show any abnormal fixation. A left lobo-isthmectomy was performed. Histologic examination revealed an intrathyroid metastasis of kidney carcinoma.

RESUMEN

We report a case of a gaseous gangrene of the thigh, six months after setting a polypropylene monofilament suburethral sling on transobturator position. This rare complication has severely engaged the vital prognosis of a 39-years-old woman, operate for stress urinary incontinence. According to the available data, we discuss the predictive factors of such complications.

RESUMEN

OBJECTIVE: To evaluate postoperative and mid-term results of carotid surgery (CS) with somatosensory evoked potentials (SEP) monitoring. METHODS: Between 1998 and 2006, 141 CS in 124 patients were performed under general anesthesia. Selective shunting was based on SEP abnormality. Shunting criteria were: reduction up to 50% of the amplitude or latency increasing up to 10%. Early results and follow-up data are analyzed retrospectively. RESULTS: Shunting rate was 6%, 3 strokes (two transient strokes) occurred and one patient died of perioperative myocardial ischemia. The cumulative stroke and death rate at 30 days was 1.4%. CONCLUSIONS: Intra-operative SEP monitoring with selective shunting may be safely performed in carotid surgery.

RESUMEN

OBJECTIVES: To report on the value of diagnostic videothoracoscopy in patients with possible penetrating cardiac wounds. METHODS: Thirteen patients admitted over a 4 year period with hemodynamic stability and a penetrating injury in cardiac proximity had exploratory videothoracoscopy. All data related to those patients were retrospectively reviewed. RESULTS: Eighty-five percent of patients had videothoracoscopy within 8 h of trauma. In most cases (eight of 13), operations were performed on patients in the supine position with the chest slightly rotated. Nine patients had a left hemothorax, five had pulmonary lacerations and five had a bleeding parietal vessel. Pericardial exploration was achieved either by direct vision (nine patients), or by the performance of a pericardial window (four patients). Acute hemopericardium related to a cardiac wound was diagnosed in two patients. Procedures included evacuation of clotted hemothorax (six patients), stapling of pulmonary laceration (four patients), and electrocoagulation of bleeding parietal vessel (four patients). Four patients required conversion to thoracotomy: two for repair of a cardiac wound, one for adequate exposure of the pericardium and one for ligation of a bleeding intercostal artery. The mean operative time was 37+/-23 min. Two patients experienced postoperative complications (coagulopathy, subcutaneous emphysema) and the in-hospital mortality was 0%. The mean hospital stay was 10+/-4 days. CONCLUSIONS: In the hands of an experienced surgeon, videothoracoscopy may represent a valid alternative to subxiphoid pericardial window in patients with hemodynamic stability and a suspected cardiac wound. Videothoracoscopy can rule out a cardiac injury and allows for the performance of associated procedures such as diaphragm assessment/repair, evacuation of clotted hemothorax, hemostasis of parietal vessels or pulmonary laceration and removal of projectiles.

RESUMEN

Wuchereria bancrofti gravid adult female worms were detected in a mediastinal lymph node in a 76-year old man. The patient also had lung carcinoma. A blood cell counts did not show any eosinophilia, and three consecutive night blood samples were also negative for microfilariae. Filariasis and neoplasm association was purely coincidental. Epidemiological and histopathological aspects of adult filariasis are described.

RESUMEN

We report a new case of pleomorphous adenoma of the submaxillary glands with multiple lung metastases. Histological proof was obtained on the thoracoscopic surgical specimen. Clinically, this benign tumor presents as a malignant tumor. Diagnosis has been a subject of debate; surgical resection is indicated. Diagnosis is achieved by elimination in a patient with one or several nodules occurring in a context of recurrent pleomorphous adenoma.

RESUMEN

BACKGROUND: The goal of the study was to report our 7-year experience with single-stage bilateral videothoracoscopy for bleb excision and pleural abrasion in patients suffering primary spontaneous pneumothorax. METHODS: From November 1992 through June 1999, 12 men were operated on in our department. Preoperative chest computed tomographic scans were obtained for all patients. Operative indications included simultaneous bilateral pneumothorax (n = 2), contralateral recurrence (n = 1), ipsilateral recurrence with contralateral blebs or bullae, and job restrictions (n = 9). RESULTS: Mean age at operation was 26+/-6 years. All patients had multiple blebs or bullae located in upper lobes, and 4 patients (33%) had pleural adhesions. All blebs or bullae were resected at operation. The mean number of staple cartridges was 5 per patient (range, 3 to 8). All patients had bilateral pleurabrasion. There were no perioperative complications and no conversion to thoracotomy. The mean operative time was 168+/-17 minutes (range, 140 to 190 minutes). The mean drainage time was 5 days (range, 4 to 26 days) and the mean hospital stay was 7.7+/-1.4 days for 11 of 12 patients. Postoperative complications included prolonged air leak (16.5%), incomplete lung reexpansion (25%), and pleural effusion (8.5%). One patient required reoperation on the right side through transaxillary thoracotomy within 1 month of videothoracoscopy for pleurodesis failure. Follow-up was 100% complete. Mean follow-up is 50+/-34 months (range, 9 to 88 months) and no patient has had recurrence of pneumothorax. All patients except one returned to full occupational activity within 5 weeks of surgery. CONCLUSIONS: Single-stage bilateral videothoracoscopy for bilateral bleb excision and pleurabrasion is a safe procedure that does not result in major complications and provides excellent long-term results. This approach could be considered in young patients with bilateral primary spontaneous pneumothorax, or in those requiring radical therapy for the prevention of ipsilateral and contralateral recurrences.

RESUMEN

We report two cases of obturator hernia diagnosed on CT scans. This examination contributes to both diagnosis and evaluation of prognosis allowing for improved treatment by reducing the number of intestinal resections. Abdominal CT is becoming the first line examination for all occlusion or subocclusion syndromes with no obvious diagnosis.
