Transplant Procedure

We evaluated 50 patients who had renal transplants and were sent for Doppler Ultrasound for complications, after the transplant procedure. Ages of the patients ranged from 20 to 65 years, 39 were male and 11 were female. In inclusions only first month post op patients were included and only those patients were considered who had some sort of complications on ultrasound at some stage of the follow up.Following complications were noticed: Diminished corticomedullary demarcations, increased echogenicity with raised R I (20 pt). Perinephric collections other than haematoma (13 pt). Perinephric haematoma (06 pt). Obstructed transplanted kidney ( 05 pt). Diminished arterial vascularity of the kidney (04 pt) Renal vein thrombosis (02 pt). RI was found to be raised in increased echogenicity, obstructed hydronephrotic kidney, diminished arterial supply and was disturbed in RVT.

Radiologic Assessment

Introduction International guidelines propose color Doppler ultrasound (CDUS) and contrast-enhanced computed tomography (CT) as primary imaging techniques in the diagnosis of acute splanchnic vein thrombosis. However, their reliability in this context is poorly investigated. Therefore, the aim of our study was to validate CDUS and CT in the radiologic assessment of acute splanchnic vein thrombosis, using direct transjugular spleno-portography as gold standard. Materials and methods 49 patients with non-malignant acute splanchnic vein thrombosis were included in a retrospective, multicenter analysis. The thrombosis’ extent in five regions of the splanchnic venous system (right and left intrahepatic portal vein, main trunk of the portal vein, splenic vein, superior mesenteric vein) and the degree of thrombosis (patent, partial thrombosis, complete thrombosis) were assessed by portography, CDUS and CT in a blinded manner. Reliability of CDUS and CT with regard to portography as gold standard was analyzed by calculating Cohen’s kappa. Results Results of CDUS and CT were consistent with portography in 76.6% and 78.4% of examinations, respectively. Cohen’s kappa demonstrated that CDUS and CT delivered almost equally reliable results with regard to the portographic gold standard (k = 0.634 [p < 0.001] vs. k = 0.644 [p < 0.001]). In case of findings non-consistent with portography there was no clear trend to over- or underestimation of the degree of thrombosis in both CDUS (60.0% vs. 40.0%) and CT (59.5% vs. 40.5%). Conclusions CDUS and CT are equally reliable tools in the radiologic assessment of non-malignant acute splanchnic vein thrombosis.

Ovarian Vein Thrombosis

Ovarian vein thrombosis is an uncommon clinical entity, most familiar to radiologists as a source of postpartum sepsis, which, if unrecognized and left untreated, has the potential for septic shock, pulmonary thromboembolism, and death. Ovarian vein thrombosis also occurs with other common inflammatory and malignant conditions in the nonobstetrical patient. This article reviews the pathophysiology, predisposing conditions, clinical findings, imaging features on ultrasonography, computed tomography, and magnetic resonance imaging of acute and chronic ovarian vein thrombosis and its appropriate clinical management.

Ovarian Vein Thrombosis

Ovarian vein thrombosis (OVT) is a rare medical disorder, which is most often found in the immediate postpartum period. OVT is rarely considered idiopathic. We report a case of idiopathic OVT with pulmonary embolism in a 33-year-old woman who presented with abdominal pain. Computed tomography and postoperative pathology confirmed the diagnosis of idiopathic OVT. To date, only 12 cases of idiopathic OVT have been reported. In this case report, we present a summary of these cases and a review of literature regarding management of idiopathic OVT.

Abstract Background The anterolateral thigh (ALT) perforator flap is a commonly used flap with a predictable, though often variable, perforator anatomy. Preoperative imaging with color Doppler ultrasound (CDU) and computed tomography angiography (CTA) of ALT flap perforators can be a useful tool for flap planning. This study provides a complete review and analysis of the relevant preoperative ALT imaging literature. Methods Studies related to preoperative CDU and CTA imaging were reviewed, and information related to imaging method, sensitivity, false-positive rates, and perforator course identification (musculocutaneous vs. septocutaneous) were analyzed. Results A total of 23 studies related to preoperative ALT flap CDU and CTA imaging were included for review and analysis. Intraoperative perforator identification was compared with those found preoperatively using CDU (n = 672) and CTA (n = 531). Perforator identification sensitivity for CDU was 95.3% (95% CI: 90.9–97.6%) compared with the CTA sensitivity of 90.4% (95% confidence interval [CI]: 74.4–96.9%). The false-positive rate for CDU was 2.8% (95% CI: 1.1–4.5%) compared with 2.4% (95% CI: 0.7–4.1%) for CTA. Accuracy of perforator course identification was 95.5% (95% CI: 93.6–99.2%) for CDU and 96.9% (95% CI: 92.7–100.1%) for CTA. Conclusion CDU provides the reconstructive surgeon with greater preoperative perforator imaging sensitivity compared with CTA; however, false-positive rates are marginally higher with preoperative CDU. Preoperative imaging for ALT flap design is an effective tool, and the reconstructive surgeon should consider the data presented here when selecting a flap imaging modality.
