Recurrent epididymitis in a child without genitourinary malformations: a case report

The patient was a 12-year-old boy, who was brought to our hospital with a chief complaint of swelling and pain in the right scrotum. Color Doppler ultrasonography showed blood flow in the right testis and increased blood flow at the right epididymis. Our diagnosis was right epididymitis, and the swelling of the scrotum was improved by antibiotics. Since there was recurrence, right epididymectomy was performed. Histological diagnosis was chronic epididymitis. Postoperative, screening for abnormalities in the urinary tract revealed no malformations. Recurrent epididymitis in a child without genitourinary malformations is a very rare pathology.     

Cystic adventitial disease of the popliteal artery: report of two cases

Cystic adventitial disease (CAD) of the popliteal artery is a rare vascular disorder in which a mucin-containing cyst develops in the adventitial layer of the artery. We report two such cases, each of which was treated differently. The first case was of a 49-year-old man, treated by excision of the involved arterial segment and interposition of an autologous saphenous vein graft. The second case was of a 36-year-old man, treated by local excision of the affected arterial segment and interposition with prosthetic bypass grafting. Both patients presented with rapidly progressing intermittent claudication of the lower extremities, but without remarkable evidence of atherosclerotic disease. Physical examination revealed diminished or absent popliteal, posterior tibial and dorsalis pedis pulses in the lower extremities. Color Doppler ultrasound of the popliteal artery revealed hypoechoic cystic lesions surrounding the vessel, and popliteal arterial stenosis, in both patients. Surgery resulted in immediate improvement of the arterial pulse distal to the lesion. Both patients recovered uneventfully. Thus, resection of the involved artery segment and interposition bypass grafting, using either patient or prosthetic veins, offers favorable results for CAD of the popliteal artery.     

Acute iliac artery thrombosis and pulsatile femoral and popliteal veins in the same extremity: a case report

Systemic venous pressure is elevated in right heart failure, and this elevation may be reflected in pulsatile venous flow when there is significant tricuspid regurgitation. The presence of this systolic reversed flow in the femoral and popliteal veins may result in major difficulties for diagnosis and treatment. We report the case of a patient with signs and symptoms of acute ischemia of the right lower limb with palpable pulse in the groin and popliteal fossa. Tricuspid regurgitation was suspected by clinical examination, and Doppler ultrasonographic examination of the extremity revealed pulsatile flow in the femoral and popliteal veins while the iliac arterial axis was occluded. A preoperative angiogram revealed an underlying iliac artery thrombosis, which was successfully treated.     

Bilateral popliteal vein aneurysms

An 82-year-old man was admitted with a left hip fracture sustained in a fall. The fracture was surgically repaired. Ipsilateral leg swelling developed over the following 2 weeks. A lower extremity venous duplex scan demonstrated isolated dilatation of the popliteal veins in both lower extremities. Chronic thrombosis was noted in both popliteal veins at the level of this dilatation. Initial duplex scanning also revealed acute thrombus in the left popliteal, posterior tibial, and peroneal veins. A repeat scan 1 week later identified propagation of thrombus into the superficial femoral vein. Popliteal vein aneurysms, although rare, can cause significant morbidity and mortality. The literature is also reviewed.Presented at the Second Annual Winter Meeting of the Peripheral Vascular Surgery Society, Breckenridge, Colo., January 25–27, 1992.     

Large uterine fibroids causing mechanical obstruction of the inferior vena cava and subsequent thrombosis: a case report.

A 35-year-old woman presented with severe left leg swelling and pain after a spontaneous abortion of a 20-week fetus. Duplex ultrasound imaging confirmed venous thrombosis of the left iliac, common femoral, superficial femoral, deep femoral, greater saphenous, posterior tibial, and popliteal, peroneal, and soleal veins. A computed tomography scan showed large uterine fibroids that were completely compressing the distal inferior vena cava and both ureters, with associated hydronephrosis. A magnetic resonance venography showed the inferior vena cava proximal to the mechanical obstruction was free of thrombosis but was dilated at 27 mm in the suprarenal location. A hysterectomy was performed and an 8-pound uterus was removed. Intraoperative ultrasound of the inferior vena cava showed a patent crescent shaped vein with no thrombus and adequate venous blood flow. Pathology of the uterus showed a large leiomyoma with necrosis. Her lower extremity symptoms resolved.     

Clavicular fracture and upper-extremity deep venous thrombosis

Upper-extremity deep venous thrombosis (DVT) is considered an uncommon clinical event with considerable potential for morbidity. This article presents a case of upper-extremity DVT following a clavicular fracture. A 25-year-old man presented with pain and distortion of the left midclavicular area after falling on his left shoulder during martial arts practice. Following physical examination and radiography, he was diagnosed with a simple displaced clavicle fracture at the middle third. The patient had no previous surgery or medical problem, and did not smoke. No family history of blood clotting disorders were present and neurovascular examination appeared normal on the symmetric contralateral side. A figure-of-8 bandage was applied to support the arm and the patient was discharged. One week later, he returned with swelling and severe pain in his left arm. On examination, a DVT was suspected and the figure-of-8 brace was removed. A Doppler ultrasonography was performed and the presence of a thrombus extending from the brachial axillary veins to the distal subclavian vein with no flow in that segment was revealed. The patient was placed in a sling instead of a figure-of-8 bandage to immobilize the arm, while anticoagulation therapy with enoxaparin was started (1 mg/kg every 12 hours, 80 mg subcutaneous daily for 3 months). The swelling was reduced after 5 days. At 2-week follow-up, the patient had no pain and the swelling had completely disappeared.     

Huge popliteal arterial aneurysms in Behçet's syndrome: is ligation an alternative treatment?

Beh?et's syndrome is a multisystemic disease characterized by relapsing uveitis, oral and genital ulcerations, and vascular system involvement. The vascular involvement is seen as venous occlusion, arterial occlusion, and aneurysm formation in this disease, and the surgical treatment of a Beh?et's aneurysm has technical difficulties. In this report, we suggest that the huge popliteal artery aneurysm in Beh?et's syndrome can be treated by ligation of the popliteal artery. A 58-year-old male patient was admitted to our clinic because of an infrapopliteal great mass at the left leg. Color Doppler ultrasonography and arteriography revealed a 71 x 54 mm aneurysmal dilatation at the distal popliteal artery. Surgery did not reveal any suitable arterial formation for bypass to the distal area of the popliteal artery and tibial arteries. For this reason, we applied ligation of aneurysmal dilatation at the distal popliteal artery. The patient tolerated the operation well and had no signs of ischemia during the postoperative period. In conclusion, especially in aneurysm of arteries such as the popliteal artery, which has critical importance for maintaining distal perfusion, ligation may be a treatment method if there are no other alternatives.     

Trevor disease of the spine. Case report

The authors report the case of a 15-year-old boy who presented with left shoulder pain and paresthesia of the left hand. Imaging studies revealed an osseous lesion compressing the C-8 nerve root. The patient underwent tumor resection followed by instrumentation-augmented fusion. Histological findings were consistent with osteochondroma. The tumor most likely originated from the articular cartilage between the first rib and T-1 or between C-7 and T-1. The correct diagnosis, therefore, was dysplasia epiphysialis hemimelica (DEH), also known as Trevor disease. To the authors' knowledge, this is the first report of DEH involving the spine.     

Adventitial Cystic Disease of the Popliteal Vein: Report of a Case

Adventitial cystic disease (ACD), also known as cystic mucoid or myxomatous degeneration, is a rare vascular disease seen mainly in arteries. It is very unusual for these cystic masses to develop in a vein. We report the case of a 56-year-old woman with leg swelling caused by ACD arising in the popliteal vein. The swelling appeared after a long period of standing. Magnetic resonance imaging (MRI) showed a popliteal cystic mass and venography showed disrupted venous flow. We resected the cyst wall without venous reconstruction, after which venous blood flow normalized and her symptoms subsided. To our knowledge, this is only the third documented case of ACD arising in the popliteal vein. A misdiagnosis could easily have been made, since the mass was not obvious on physical examination and the only symptom was intermittent swelling. Thus, it is important to be aware of ACD as a possible diagnosis when examining patients with a swelling in the leg.     

Giant seminoma in abdominal retention of the testis manifested with unilateral leg pain: a case report

A 26-year-old man was admitted to the department of surgery of our hospital with a complaint of intermittent left leg pain for the past two weeks. Ultrasonography revealed reduced blood flow to the tibial artery, which suggested a vascular disease like arteriosclerosis obliterans. Enhanced computed tomography (CT) revealed a huge abdominal tumor and a 3-dimensional CT scan showed a feeding artery from the left renal artery to the huge tumor. Findings of routine blood and urine examinations were elevated levels of lactate dehydrogenase, alkaline phosphatase, and C-reactive protein. Surgical exploration revealed a giant tumor with clouded ascites in the abdominal cavity containing class V cells revealed by cytological examination. The tumor was easily resected. Its vascular pedicle was thick and hypertrophied. Thus, it could be traced to the origin of left gonadal artery. At this time, the surgeon incidentally noticed the absence of left testis in the patient's scrotum. The resected specimen was 25 x 18 x 12 cm in size, and it weighed 3000 gm. The histological finding was pure seminoma invaded to peritoneum. His leg pain was relieved after the tumor resection.     

A rare anterior sacral osteochondroma presenting as sciatica in an adult: a case report and review of the literature

Background contextOsteochondroma is the most common primary benign bone tumor and is usually located in the metaphyses of long bones and rarely in the spine or anterior sacrum. To the best of our knowledge, en bloc excision of a solitary osteochondroma of the anterior sacrum in an adult patient has not been previously reported in a peer-reviewed journal.PurposeThe purposes of this study were to document the first report of an osteochondroma of the anterior sacrum along with the clinical course and operative management and review the literature on solitary osteochondroma of the sacrum.Study design/settingThe study setting is an academic institution. This is a case report and review of the literature.Patient sampleThe patient is an adult female.Outcome measuresThe outcome measure is the visual analog score for pain.MethodsA 54-year-old woman presented with 9/10 disabling low back and radicular pain in the left lower extremity. Radiologic studies showed a pedunculated mass occurring from the anterior sacrum thought to be causing nerve root compression. The patient received en bloc excision of the mass through an abdominal retroperitoneal approach. We also conducted a literature review of solitary sacral osteochondroma in peer-reviewed journals.ResultsHistologic studies confirmed the mass to be an osteochondroma without pathologic signs of malignant transformation. The patient complained of dysesthesia in the left leg after surgery, which progressively improved completely over 8 months after the operation. At the 2-year follow-up, there was no evidence of local recurrence and she was pain free. A literature review revealed one previous case of en block resection of a solitary osteochondroma, but it involved the posterior sacrum.ConclusionsSolitary osteochondroma can rarely present in the sacrum as low back pain and sciatica. In general, when osteochondroma causes pain in an adult, we should think that some structure is impinged or that it could have initiated a malignant transformation, so en bloc excision should be used to remove the tumor and histologic studies performed to assess for malignant transformation. Battered nerve root syndrome may take up to 8 months to resolve.

An unusual presentation of a popliteal arteriovenous fistula after primary total knee arthroplasty

Iatrogenic popliteal arteriovenous fistula after total knee arthroplasty is extremely rare (Int Surg. 1998 Jul-Sep;83(3):198-201). We report this complication in a 78-year-old female patient 3 years after total knee arthroplasty. She presented with symptoms of persistent swelling and recurrent cellulitis of the operated leg. A fistula was detected between the popliteal artery and vein by vascular duplex scan and confirmed by peripheral arteriography. This was successfully treated by resection of the fistula and direct repair of the artery and vein.     

Unusual presentation of an osteochondroma

Osteochondromas or exostoses are the most common benign tumours of the bone. They occur during the growth period and are rarely responsible for vascular complications. We report a case of a patient with osteochondroma in the lower limb and vascular complication caused by compression of the popliteal artery. The patient presented with the gangrene of the medial three toes at the ipsilateral right lower limb. Magnetic resonance angiography and radiography screening identified the vascular lesion and the bone tumour. Surgical treatment of osteochondroma was performed with satisfactory postoperative evolution.     

A case of primary adenocarcinoma of the epididymis

A 68-year-old man presented with right intrascrotal swelling. On palpation, a hard tumor without pain was recognized at the head of the right epididymis. Power Doppler ultrasonography revealed blood flow signals within the tumor. Surgical exploration was performed under the tentative diagnosis as possible malignant tumor of the epididymis. The right epididymis adhered to the testis so strongly, that the epididymis was resected with the testis. Pathological diagnosis was moderately differentiated adenocarcinoma of the epididymis. The results of general examinations on possible presence of primary lesions in other organs were all negative. Finally, the diagnosis of primary adenocarcinoma of the epididymis was obtained. He remains free of disease 17 months after surgery.     

Sequelae after limb-sparing surgery with major vascular resection for tumor of the lower extremity

PURPOSE: Limb-sparing procedures have recently replaced amputations as the treatment for tumors invading major vessels of the lower extremity. Major arteries must be reconstructed for limb salvage. The veins are not usually reconstructed. This study was undertaken to investigate the sequelae such as chronic venous disease after venous resection for tumors. METHODS: Ten patients who underwent limb-sparing surgery for a tumor of the lower extremity or retroperitoneum that required major vascular resection were studied. The median follow-up period was 48 months. After combined resection of a major artery and vein, arterial reconstruction was performed. The veins were not reconstructed. The resected veins included the inferior vena cava (n = 2), the external iliac and common femoral veins (n = 3), the superficial femoral vein (n = 3), and the popliteal vein (n = 2). The main outcome measures were clinical classification of chronic venous disease in 10 patients and air plethysmography in seven patients. RESULTS: Clinical classification was C(0A) in 6 patients, C(3A) in 1 patient, C(3S) in 2 patients, and C(4S) in 1 patient. Venous claudication with uncontrollable edema was observed in two patients with C(3S) disease. Pain and itching with inflammatory skin changes were observed in one patient with C(4S) disease. These three patients had undergone resection of the femoral vein, including the deep femoral vein along with proximal adductor muscles. Air plethysmography revealed that the ejection fraction was significantly lower and the residual volume fraction was significantly higher in the three patients with symptoms than in symptom-free patients. CONCLUSIONS: Significant chronic venous disease was observed in the patients who underwent combined resection of the femoral vein, the deep femoral vein, and the adductor muscles for a tumor.     

Sciatica: an early manifestation of thoracic vertebral osteochondroma

We describe a 36-year-old woman with a thoracic vertebral osteochondroma who presented with radicular leg pain. This benign tumor is uncommon in the vertebral column, and radicular pain is an unusual manifestation of a thoracic spinal lesion. Myelography and computed tomography aided in diagnosis; surgical resection resulted in an excellent clinical response.     

Increased locoregional blood flow in brain tumors after cervical spinal cord stimulation

OBJECT: Patients with high-grade gliomas have poor prognoses following standard treatment. Generally, malignant brain tumors have a decreased blood flow that results in increased resistance to radiation and reduced delivery of chemotherapeutic agents and oxygen. The aim of the present study was to assess the effect of spinal cord stimulation (SCS) on locoregional blood flow in high-grade tumors in the brain. METHODS: Fifteen patients (11 with Grade III and four with Grade IV brain tumors) had SCS devices inserted prior to scheduled radiotherapy. Both before and after SCS, the patients underwent the following procedures: 1) single-photon emission computerized tomography (SPECT) scanning; 2) middle cerebral artery (MCA) blood flow velocity measurements (centimeters/second) with the aid of transcranial Doppler (TCD) ultrasonography; and 3) common carotid artery (CCA) blood flow volume quantification (milliliters/minute) based on time-domain processing by using color Doppler ultrasonography. The indices demonstrated on SPECT scanning before SCS were significantly lower (p < 0.001) in tumor sites compared with those in peritumoral sites (32%) and healthy contralateral areas (41%). Poststimulation results revealed the following: 1) a mean increase of 15% in tumor blood flow in 75% of patients (p = 0.033), as demonstrated on SPECT scanning: 2) a mean increase of greater than 18% in systolic and diastolic blood flow velocities in both tumorous and healthy MCAs in all but one patient (p < 0.002), as exhibited on TCD ultrasonography; and 3) a mean increase of greater than 60% in blood flow volume in tumorous and healthy CCAs in all patients (p < 0.013), as revealed on color Doppler ultrasonography studies. CONCLUSIONS: Preliminary data show that SCS can modify locoregional blood flow in high-grade malignant tumors in the brain, thus indicating that SCS could be used to improve blood flow, oxygenation, and drug delivery to such tumors and could be a useful adjuvant in chemoradiotherapy.

Magnet Resonance Angiography versus Conventional Angiography for the Planning of Reconstructive Surgeries

Abstract Summary: Assessing the vascular status and anatomy of the lower extremity is of crucial importance when planning the coverage of a tissue defect with a free flap. The standard techniques comprise the clinical examination, Doppler ultrasound and Doppler sonography for healthy patients without suspected direct trauma to the vascular system, and conventional digital subtraction angiography (DSA), respectively, in case of traumatized vessels or patients with peripheral arterial obstructive disease. Materials: We have conducted a prospective study for the comparison of the magnetic resonance angiography (MRA) to the conventional DSA. Fourteen patients were examined presurgically by means of both a conventional DSA and an MRA before undergoing planned microvascular coverage of tissue defects of the lower extremity. The surgeon, based on a questionnaire, assessed and compared both examination results according to their information content. Furthermore, the presurgically planned level and localization of the vascular anastomoses and the intraoperative findings were compared postoperatively. Results: The MRA examination yielded sufficient information on the vascular anatomy to enable the surgeon to carry out a detailed presurgical planning. Additionally, the use of MRA showed clear advantages with regard to both patient and user comfort. Conclusion: Taking into account the advantages for the assessment of vessels using MRA, in particular when considering the impact of the frequently varying vascular anatomy of the lower leg on reconstructive surgery, as well as the significantly lower morbidity rate of the examination itself, then the MRA must be regarded as a safe alternative to the DSA.
